     A steep correction in technology and telecommunications stocks, a steadily
broadening stock market, and increasing signs of a slowing economy led to
improved returns for value-oriented investors over the six-month period  covered
in this report. American Century's conservative equity funds  provided positive
returns in this  environment, even as the overall market, measured by the S&P
500 Index, posted negative results.

     Turning to corporate matters, Chase Manhattan Corp. recently announced
plans to acquire J.P. Morgan & Co., a substantial minority shareholder in
American Century Companies, Inc. since 1998. If the transaction is completed as
expected, J.P. Morgan Chase, the new enterprise, will own the shares of American
Century currently held by Morgan. Corporate control of American Century is not
affected by this transaction. We will be exploring ways to partner with J.P.
Morgan Chase for the benefit of fund shareholders.

     In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to share chairman of the
board responsibilities, and also named American Century President William M.
Lyons chief executive officer, giving him ultimate management responsibility for
the entire company.

     These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue additional worthwhile endeavors. For example, Jim Stowers III will focus
more on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next  generation of portfolio management
technologies). However, his first priority will be continuing involvement on the
investment teams responsible for Ultra and Veedot Funds.

     As always, we appreciate your continued confidence in American Century.

Sincerely,
/s/James E. Stowers, Jr.                  /s/James E Stowers III

Report Highlights
--------------------------------------------------------------------------------

Investment terms are defined in the Glossary on pages 51-52.

MARKET PERSPECTIVE

*   The six months ended September 2000 saw major shifts in sentiment, as
    investors concerned about high technology valuations and a slowing economy
    sought the relative security of Old Economy companies before returning to
    the tech arena with a new-found sense of discrimination.

*   Against a backdrop of volatility driven by uncertainty and persistent
    inflation concerns, the market appeared to broaden. In a brief respite from
    the technology run-up, companies with solid fundamentals gained strength,
    particularly mid-capitalization firms valued at levels investors deemed
    reasonable.

VALUE

*   Value gained 7.01% during the period, outperforming its benchmark, the
    Lipper Multi-Cap Value Index, which gained 4.70%. The S&P 500 fell 3.60%.

*   Banks and financial services firms were Value's strongest contributors to
    performance, as investors gained confidence that interest rate increases
    might cease for now. Electrical utility companies also helped performance.

*   Value's holdings of telecommunications companies, particularly those in the
    long-distance industry, detracted from performance. These firms suffered in
    a highly competitive environment, and were further restrained by the
    downturn in technology.

EQUITY INCOME

*   Equity Income gained 9.60%, beating its benchmark, the Lipper Equity Income
    Index, which returned 4.73%.

*   A diverse group comprised Equity Income's best contributors, including
    stocks of chemical companies, insurance and financial services firms, banks,
    and electrical utilities.

*   Technology holdings restrained performance, as did those of
    telecommunications firms struggling with tough competition and the broader
    technology decline.

SMALL CAP VALUE

*   Small Cap Value gained 13.58% during the period, surpassing its benchmark,
    the S&P SmallCap 600/BARRA Value Index, which returned 9.75%.

*   Holdings in energy exploration and production firms, built during an earlier
    downturn in this industry, provided the largest contribution to the fund's
    performance during the period. Strength in the utility sector was also
    beneficial.

*   The financial sector also contributed positively to performance, as smaller
    insurance companies emerged from an unfavorable market perception related to
    the rising interest-rate environment.

*   Select stocks, including those of an engineering software firm and a forest
    and paper products company, dampened performance.

LARGE CAP VALUE

*   Large Cap Value gained 4.14%, exactly matching the return posted by its
    benchmark, the S&P 500/BARRA Value Index.

*   Holdings in several industries contributed to performance, including
    financial services, property and casualty insurance, defense/aerospace, and
    pharmaceuticals.

*   Holdings in telecommunications companies hurt performance, as such firms
    suffered from an intensely competitive environment and the downturn in
    technology.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------

Mark Mallon, chief investment officer, specialty, asset allocation, and growth
and income equities

A RENAISSANCE FOR VALUE STOCKS

     Value stocks rebounded during the six months ended September 30, 2000,
proving to be among the market leaders in that timeframe. During the second and
third quarters of 2000, the Standard & Poor's 500/BARRA Value Index returned
4.14%, while the S&P 500  fell 3.60%.

SHIFTS AMID QUARTERS

     At the start of the six-month period, the market experienced a shift away
from New Economy technology companies. By April 10, a steady drumbeat of Fed
interest rate increases, the judgment against Microsoft, and rich valuations
across the technology sector propelled investors into other sectors of the
market.

     This shift played to value-oriented funds, as Old Economy companies became
beacons for defensive-minded investors. Then, late in the second  quarter,
investors began moving back into technology stocks -- albeit with a greater
degree of discrimination --  as concerns about interest rates and  inflation
began to cool.

VALUE BACK IN VOGUE

     In the third quarter, though, value was back in style. Investors began to
doubt the sustainability of earnings implicit in many technology company share
prices. Coming off the speculative froth that drove technology shares higher in
late 1999 and early 2000, investors paid much closer attention to what they were
paying for a company's earnings.

     Looking for alternatives, they found solid fundamentals in three areas that
had helped populate the value universe during the tech run-up. First was the
utilities sector, offering relative safety, healthy dividends, and the fruits of
deregulation. Second was energy, where rising oil and natural gas prices lifted
most shares. Finally, the perception that the Fed had, for at least the time
being, finished raising rates boosted the previously downtrodden financial
sector.

     Overall, mid-capitalization stocks provided the best performance among
value companies. During the third  quarter, the S&P MidCap 400/BARRA Value Index
returned 13.05%, while the S&P 500 lost 0.97%.

OPPORTUNITIES STILL REMAIN

     Many intriguing values still beckon in the aftermath of the narrow market
advance we saw in late 1999 and early 2000. The question going forward: Will the
market's appetite for reasonably priced stocks continue?

     The value style is a time-tested approach for making money with stocks. If
the  market continues to reward those companies that are rebounding from
temporary difficulties or that have fallen out of favor, it's our goal to  be
positioned so that fund shareholders fully participate.

Value--Q&A
--------------------------------------------------------------------------------

[photo of Phil Davidson (left) and Scott Moore]

     An interview with Phil Davidson (left) and Scott Moore, portfolio managers
on the Value investment team.

HOW DID VALUE PERFORM FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2000?

     Value was up 7.01%* for the period. Its benchmark, the Lipper Multi-Cap
Value Index, gained 4.70% for the six months. The fund's previous benchmark, the
S&P 500/BARRA Value Index, rose 4.14% in the same time frame, while the S&P 500
Index, considered to be representative of the broad market declined 3.60%.

WHY WAS THE FUND'S BENCHMARK CHANGED?

     Value's original benchmark, the S&P 500/BARRA Value Index, reflects the
performance of S&P 500 stocks that have characteristics associated with
value-style securities. But because the index tracks stocks in the S&P 500, it
reflects the performance of generally larger companies. In contrast, Value tends
to invest across the capitalization spectrum.

     In September 1999, Lipper Inc., the leading mutual fund ranking
organization, introduced value-oriented indices based on investment style as
well as  capitalization. Its new Lipper Multi-Cap Value Index is not restricted
by capitalization, and reflects the performance of small-, medium- and large-cap
value stocks. In our opinion, it is more representative of Value's portfolio.

WHAT FACTORS CONTRIBUTED TO VALUE'S  PERFORMANCE?

     First and foremost, the market played more to our strength. With the
economy appearing to slow after six interest rate increases by the Federal
Reserve since mid-1999, investors grew more nervous about corporate earnings,
especially for richly valued technology companies and larger multinationals with
exposure to a plummeting European currency. Their trepidation seemed justified
during the third quarter, when several household-name technology companies and
consumer products giants warned of lower-than-expected earnings. The news took
money out of growth stocks, as investors sought more reasonably priced companies
with predictable earnings prospects -- Value's hunting ground.

     During the past several years, which have been exceedingly frustrating for
value-oriented investors, we've detailed our intention to stick closely with our
disciplined value approach, despite the temptation to try what was working in
the market at the time. Our positive results for this short-term period help
illustrate why we refused to budge.

WHICH INDUSTRIES OR STOCKS CONTRIBUTED THE MOST TO RETURNS?

     Banks and financial services firms were among Value's top contributors. The
financial sector, which includes banks, brokerages, credit card companies,
insurance providers and financial services firms, generally struggled as
interest rates rose. However, in the second and third quarters, investors grew
increasingly confident that the Fed would not raise rates further and began to
look more favorably on bank stocks.

     Although a number of holdings in this group fared well during the period,
two firms -- Summit Bancorp and First Virginia Banks, Inc. -- should be noted.

Value--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

     We built a position in each firm on the basis of its sound fundamentals.
New Jersey-based Summit, the 25th-largest bank holding company in the United
States, struggled moderately with rising rates, but nonetheless held its own via
the introduction of new products and some recent acquisitions. Summit's stock
was further enhanced by speculation that it would be acquired by FleetBoston
Financial -- a deal that was announced the day after the third quarter closed.

     First Virginia is another strong regional bank, with nearly 400 offices
serving Virginia, Maryland and Tennessee. This stock has been volatile in recent
months, following a sharp selloff that started in late 1999 when rates began
rising. First Virginia's low price, combined with its strong underwriting,
deposit franchise, and equity capitalization, has led us to maintain our
position.

ASIDE FROM BANKS, WERE THERE OTHER HOLDINGS IN THE FINANCIAL SECTOR THAT
PERFORMED WELL?

     Yes. We were pleased with our stake in MGIC Investment, a holding company
whose primary subsidiary is Mortgage Guaranty Insurance Corporation (MGIC). MGIC
is the leading provider of private mortgage insurance. A weak
mortgage-origination market and rising rates had weighed on the firm, and it
additionally struggled as an Old Economy stock. We were confident in MGIC's
fundamental health and bought into its price weakness. MGIC subsequently enjoyed
a dramatic recovery -- our shares essentially doubled in value during the
period.

WHICH OTHER INDUSTRIES OR STOCKS ADDED TO RETURNS?

     Electric utilities were another bright spot for Value, buoyed by FPL Group,
Inc. FPL's principal subsidiary, Florida Power and Light, serves more than seven
million customers on the eastern seaboard and in southern Florida. This is a
sound, well-managed firm whose balance sheet is one of the industry's strongest.
FPL's stock began to rebound in April as investors began exiting technology, and
rose again in July when the company announced it would merge with Entergy
Corporation to become one of the largest U.S. electric utilities and power
producers.

     A second winner in the utility space was another Florida company, Florida
Progress Group, which supplies electricity to western and central Florida. This
stock began moving up with the industry in general when investors began looking
for safer havens in March and April. More recently, Florida Progress Group's
shareholders approved a proposed acquisition by Carolina Power and Light in a
combination cash-and-stock deal, to which investors responded quite positively.

     Incidentally, we don't specifically hunt for companies "in play." The same
characteristics that make a company attractive to us as a potential portfolio
candidate -- a sound balance sheet, a strong underlying business, and a low
price relative to its fair market value -- are also attractive to companies
shopping for acquisition candidates. This was the case in the examples we
mentioned.

WHICH SECTORS OR STOCKS WERE  DISAPPOINTING?

     Value's positions in telecommunications companies (mainly on the
long-distance side of the industry) detracted the most from performance. A
highly competitive environment, as well as "guilt by association" during the
recent downturn in technology-oriented companies, have pressured telecom firms.
Our greatest detractor in this group was Sprint Corp., a provider of local
tele-

Value--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

phone and long-distance services. Sprint agreed in October 1999 to be
acquired by WorldCom, Inc., a deal we thought would enhance both firms. However,
in June, regulators blocked the deal on the belief that the combined company
would have unfair market advantages and reduce competition. This decision, along
with slowing growth in Sprint's core long-distance business and increased
dilution of the company's shares to fund new growth initiatives, resulted in
poor performance. Looking longer term, we believe that Sprint's strategically
well positioned assets and solid financial position,  coupled with the
industry's excellent growth prospects, bode well for the firm. We are holding
this position.

     Large-cap technology firms also struggled as a group during the six months.
Value was underweight in  technology companies because their valuations usually
fall outside of our price-driven parameters. Unfortunately, the few large
technology firms we held were liabilities. Our worst tech disappointment was
Xerox, which has  suffered sharp earnings disappointments following a difficult
realignment of its sales force and slow sales of its higher-end products. In
addition, the company recently came under investigation by the Securities and
Exchange Commission regarding accounting issues in its Mexican operations. That
was enough for us -- we sold our entire position at prices significantly higher
than where the stock is now.

WHAT CHANGES HAVE YOU MADE TO THE PORTFOLIO SINCE THE LAST REPORT?

     We substantially reduced our exposure to the food and beverage group, from
7.45% of investments at the start of the period to less than 3% at its close, as
several key holdings reached what we perceived to be fair market value. We also
trimmed our stake in several  medical providers, including HCA -- The Healtcare
Co., which was a top  contributor to performance. Finally, based on our belief
that prices for oil and gas have plateaued, we moved out of Baker Hughes.

     On the buy side, we added to our stake in transportation with the purchase
of Union Pacific Railroad (UNP). Its stock has been hurt by rising oil prices --
fuel is a major cost for UNP -- and by its 1999 acquisition of Southern Pacific
Railroad (SPR), which resulted in serious operating problems. The company has
now completed integration of SPR, and we're optimistic that any move in oil
prices to a more normal range will increase margins. We also built an overweight
position in several high-quality specialty chemical companies, including Praxair
and Air Products and Chemicals, as fundamentals continued to improve for these
companies.

WHAT'S YOUR OUTLOOK FOR VALUE INVESTING?

     We're optimistic. As we stated earlier, it's too soon to know if what we're
seeing is a true and sustainable rotation. In the meantime, we remain committed
to our discipline of buying undervalued, leading businesses that have transitory
issues affecting the price of their stocks. In recent months, broad market
factors, rather than company-specific issues, have further depressed prices, so
we are finding an abundance of compelling stocks that meet our investment
criteria. We believe that these stocks offer investors good opportunities for
handsome, risk-adjusted returns at  reasonable prices.

*Futures contracts typically are based on a stock index, such as the S&P 500,
and tend to track the performance of the index while remaining very liquid (easy
to buy and sell). By investing its cash assets in index futures, the fund can
have full exposure to stocks and have easy access to the money. Temporary cash
investments, less the required reserves for futures contracts, are 4.7%.

Equity Income--Q&A
--------------------------------------------------------------------------------

     An interview with Phil Davidson and Scott Moore, portfolio managers on the
Equity Income investment team. A photo of Phil and Scott appears on page 5.

HOW DID EQUITY INCOME PERFORM DURING THE FIRST HALF OF ITS FISCAL YEAR?

     Equity Income gained 9.60%* for the six months ended September 30, 2000,  a
significantly higher gain than the 4.73% increase posted by its benchmark, the
Lipper Equity Income Index. In contrast, the S&P 500 Index declined 3.60% over
the same period.

     The third quarter of 2000 was particularly rewarding for the fund: It
gained 8.45% from July through September. Taking a longer view, Equity Income's
average annual return of 15.39% for the past five years compares favorably
against the 13.56% average annual return for the average equity income fund
tracked by Lipper Inc.

WHAT FACTORS CONTRIBUTED TO THE FUND'S PERFORMANCE?

     Significantly, the market played more to our strength. With the economy
appearing to slow after six interest rate increases by the Federal Reserve since
mid-1999, investors became nervous about corporate earnings, particularly for
technology companies and multinational firms with exposure to a plummeting
European currency. Investors' trepidation seemed justified during the third
quarter, when several technology companies and consumer products giants warned
of lower-than-expected earnings. The news drove money out of growth stocks as
investors sought more reasonably priced companies with predictable  earnings
prospects -- Equity Income's hunting ground.

     Over the past several years, which have been exceedingly frustrating for
value-oriented investors, we detailed our intention to stick closely with our
disciplined value approach, despite the temptation to try what was "working" in
the market at the time. Our positive results for this short-term period help
illustrate why we refused to budge.

WHAT STOCKS OR SECTORS CONTRIBUTED TO THE FUND'S PERFORMANCE?

     Specialty chemical company Bush Boake Allen was Equity Income's top
contributor to performance. Bush Boake is a global producer of flavor,
fragrance, and aroma chemicals used in consumer products. We bought the stock
due to BBA's strong fundamentals and reasonable valuation. In April,
International Paper put up for sale its nearly 70% ownership in the company to
fund an acquisition in its core paper business. Industry leader International
Flavors  and Fragrances announced in early September that it would buy Bush
Boake Allen. We sold the stock at a gain to the fund.

     Another top pick was insurance  and financial services firm MetLife. We
bought MetLife's convertible preferred stock in the spring on the company's
initial public offering. MetLife's new  status was well received, and we sold
our position at a significant gain.

     Our bank stocks were also strong contributors. The improving interest rate
environment benefited most financial stocks, particularly banks. Summit Bancorp,
our second-largest contributor to performance, is an excellent example. We liked
Summit's dominant market share and quality balance sheet. The company's
fundamentals remained solid

Equity Income--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

during the previous two quarters despite industry pressure, and its stock
price was further lifted by speculation that it would be acquired by FleetBoston
Financial, a deal that was announced the day after the third quarter.

WERE THERE OTHER HOLDINGS THAT  CONTRIBUTED SIGNIFICANTLY?

     Our holdings in electric utilities are an example of the virtue of
patience. This was another classic value group that was passed over during the
tech rally, but it recovered when investors rediscovered the industry's
dependable earnings, attractive yields and consistent growth opportunities. FPL
Group is benefiting from strong customer growth and rising per-customer usage,
and has exceeded earnings expectations over the past few quarters. Additionally,
the announcement in July that FPL would merge sometime next year with Entergy
Corporation to form one of the largest utility companies in the country was
received favorably by the market and the stock appreciated substantially.

     UST Inc., the dominant player in the smokeless tobacco market, was also a
positive contributor. In early 2000, we took advantage of depressed prices and
bought the stock when we felt it was unfairly punished over an antitrust ruling.
The stock recovered, and speculation that UST may be a takeover candidate
further boosted its value.

WHAT STOCKS OR SECTORS DETRACTED FROM EQUITY INCOME'S PERFORMANCE?

     We could not completely dodge the technology sector's broad decline,
although strong stock selection and our  underweight position helped mitigate
the impact. Xerox was one holding that detracted from performance. We cut our
losses and sold the position before the stock's value further declined when the
company unexpectedly announced that third-quarter sales would come in below
expectations.

     Equity Income's position in telecommunications companies (mainly on the
long-distance side of the industry) also detracted from performance. A highly
competitive environment, as well as "guilt by association" during the recent
downturn in technology-oriented companies, have pressured telecom firms. Our
greatest detractor in this group was Sprint Corp., a provider of local telephone
and long-distance services. Sprint agreed in October 1999 to be acquired by
WorldCom -- a deal we thought would enhance both firms. However, in June,
regulators blocked the deal on the belief that the combined company would have
unfair market advantages and reduce competition. This decision, along with
slowing growth in Sprint's core long- distance businesses and increased
dilution of the company's shares to fund new growth initiatives, resulted in
poor performance. Looking longer term, we believe that Sprint's strategically
well positioned assets and solid financial position, coupled with the industry's
excellent growth prospects, bode well for the firm. We are holding this
position.

WHAT SIGNIFICANT CHANGES DID YOU MAKE TO THE PORTFOLIO DURING THE SIX MONTHS?

     We reduced our exposure to the food and beverage industry. We see less
investment opportunity in this area, but will continue to hold names we believe
can withstand the difficult competitive environment. We also trimmed our  stake
in the bank industry due to the outperformance of the group.

WHAT ARE ATTRACTIVE AREAS GOING FORWARD?

     Information Services is an industry that has served us well and one in
which we see many attractive investments. Many investors discarded these stocks
during the first quarter after the group in general completed one-time-only
business related to Y2K. In our case, we believe our holdings in this area will
continue to contribute to performance  as industry leaders, such as Computer
Sciences, benefit from the worldwide trend of outsourcing information
technology services.

     We also increased our weighting  in railroads, including Union Pacific,
believing the industry -- and this  company especially -- has worked through
operational issues arising from merger activity and is now in a position to
regain market share lost to truckers. These companies would also benefit from
declining fuel costs. This convertible preferred is an attractive vehicle for
this fund.

WHAT IS YOUR OUTLOOK FOR THE MARKET  AND THE FUND?

     We are optimistic. Although it's too soon to know if the resurgence we're
seeing in value-oriented investing is  sustainable, we remain committed to our
disciplined investment strategy.  We continue to search for undervalued
businesses that have temporary problems affecting their stock price. The good
news is that we are finding a wealth of compelling stocks that meet our
investment criteria. We believe that these companies offer investors good
opportunities for handsome, risk- adjusted returns at reasonable prices.

*Futures contracts typically are based on a stock index, such as the S&P 500,
and tend to track the performance of the index while remaining very liquid (easy
to buy and sell).  By investing its cash assets in index futures, the fund can
have full exposure to stocks and have easy access to the money. Temporary cash
investments, less the required reserves for futures contracts, are 2.2%.

GROWTH OF $10,000 OVER LIFE OF FUND

The graph at left shows the growth of a $10,000 investment over the life of the
fund, while the graph below shows the fund's year-by-year performance. The S&P
SmallCap 600/BARRA Value Index is provided for comparison in each graph. Small
Cap Value's total returns include operating expenses (such as transaction costs
and management fees) that reduce returns, while the total returns of the S&P
SmallCap 600/BARRA Value Index do not. The graphs are based on Investor Class
shares only; performance for other classes will vary due to differences in fee
structures (see the Total Returns table above). Past performance does not
guarantee future results. Investment return and principal value will fluctuate,
and  redemption value may be more or less than original cost.

Small Cap Value--Q&A
--------------------------------------------------------------------------------

[photo of Todd Vingers (left) and Ben Giele]

     An interview with Todd Vingers (left) and Ben Giele, portfolio managers on
the Small Cap Value investment team.

HOW DID SMALL CAP VALUE PERFORM  DURING THE SIX MONTHS ENDED  SEPTEMBER 30,
2000?

     Small Cap Value gained 13.58%*, outperforming its benchmark, the S&P
SmallCap 600/BARRA Value Index, which posted a 9.75% return. The average
small-cap value fund tracked by Lipper Inc. returned 7.95% in the last six
months.

     Small Cap Value's longer-term performance also has been strong. Since the
fund's inception on July 31, 1998, it has posted an annualized return of 10.61%,
significantly outpacing the 6.02% return of its benchmark. Small Cap Value also
has outperformed most of its peers.

WHAT FACTORS CONTRIBUTED TO THE FUND'S PERFORMANCE?

     To begin with, the market could no longer ignore the prices at the small
end of the value universe. The bull market in large-cap and technology stocks
triggered tremendous cash flows from small-cap value stocks during the last few
years. Over time, this continual sell-off led to increasingly more attractive
valuations on many small, fundamentally strong and profitable companies. We
stuck to our disciplined value approach, and took advantage of those conditions
to build a portfolio of inexpensive, solid stocks. Our shareholders were
well-positioned when investors rediscovered value stocks in the third quarter of
2000 -- Small Cap Value gained almost 10% during those three months alone.

     An environment in which small, sound businesses languish also creates
opportunities for companies looking to make acquisitions. Some of the factors
that make a company attractive to us -- good fundamentals at a low price --  are
also attractive to potential acquirers. This scenario played out several times
in our portfolio. One example was  Lilly Industries, Small Cap Value's top
contributor for the period. Lilly produces industrial coatings and specialty
chemical products. Attractively priced but unable to command attention from
investors, Lilly was bought out by a competitor, Valspar Corp., at a healthy
gain for investors.

     Other acquisitions that contributed to the fund's performance during the
period included buyouts of Keystone Financial, Inc. and Splash Technologies, a
manufacturer of hardware and software that link computers with color laser
copiers.

WHICH INDUSTRIES CONTRIBUTED THE MOST  TO RETURNS?

     Energy exploration and production companies provided outstanding returns
for the fund during the period. Because we had taken advantage of an earlier
downturn in this industry to buy attractively priced companies, the portfolio
was ready and waiting when these stocks moved up.

     Our best performers in this area were Pure Resources, Inc. and Swift
Energy. We were attracted to them because of their financial strength and their
positions in the natural gas market. Both companies have performed well as
rising demand for the limited supply of domestic natural gas has driven up
prices.

Small Cap Value--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

     Small Cap Value also has benefited from strong performance in the utility
sector. This is another area where we built a healthy weighting while stock
prices were depressed. Because utilities generally are viewed as safe harbors,
these stocks were lifted when investors began running for cover during April's
technology meltdown. Utilities also have benefited from sentiment that interest
rates have peaked, which tends to bode well for this capital-intensive sector.

     Because we bought our holdings when valuations were low, we caught the
earliest stages of the utility rally. Some of the companies that provided
favorable returns were Northwest Natural Gas, Maine Public Service  and People's
Energy.

WERE YOU ABLE TO TAKE ADVANTAGE OF THE STRENGTH IN THE FINANCIAL SECTOR?

     Yes, but while banks and financial services companies were grabbing
headlines, we found our success in smaller insurance companies. Many insurers
have had great fundamentals for the last two years. However, their stock prices
had been beaten down because of the perception that they would suffer in a
rising interest-rate environment.

     The truth is that some insurers, particularly mortgage insurance companies,
actually benefit from modest interest rate increases. Lenders require homebuyers
who make small down payments to carry private mortgage insurance until they
achieve 20% equity in their homes. When interest rates are flat or rising, fewer
homeowners refinance their loans. This reduces the chances that homeowners will
drop their mortgage insurance or change insurance providers. Radian and PMI, key
players in this market, have benefited from these conditions. They were two of
the best performers in our portfolio during the last six months.

     HCC Insurance Holdings, a property and casualty insurance broker, also was
a significant contributor. It has little exposure to the risk-bearing portion of
the insurance business and has taken advantage of its competitive position and
pricing power to increase fees, which has been good for earnings.

THE TECHNOLOGY SECTOR WAS VOLATILE DURING THE PERIOD. HOW DID THIS AFFECT THE
FUND?

     Technology was a mixed bag. On  the positive side, Structural Dynamics
Research, a designer of engineering software, was one of our top contributors.
This stock was punished by investors who worried the firm was losing market
share. This was not the case at all; Structural Dynamics enjoys a very  stable,
established customer base. We aggressively built our position, which
subsequently performed well.

     Technology also produced some  disappointments, including Brightpoint and
ScanSoft. Brightpoint is a cellular phone distributor that has not been able to
overcome the slowdown in demand for cellular phones. We mentioned ScanSoft in
our last report because it had purchased one of our holdings, Caere Corporation.
With Caere in the fold, ScanSoft held a dominant position in the scanning
software market during the last six months, but aggressive  discounting has hurt
the company's profits. We sold our stake in Brightpoint, but continue to hold
ScanSoft on the belief that it can turn its market position into pricing power.

Small Cap Value--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

WHAT WERE SOME OF THE OTHER  DISAPPOINTMENTS DURING THE PERIOD?

     Wausau-Mosinee Paper Corp., a  significant presence in the forest and paper
products industry, was one of  the largest detractors. In addition to
experiencing operational difficulties, this company has been suffering from weak
earnings caused by rapidly increasing pulp prices and softening demand for paper
products.

     We were also disappointed by the performance of Lancaster Colony
Corporation. A diversified company, Lancaster Colony's stock was hurt by  a
downturn in its candle business. However, we still like this solid company and
its attractive return on capital.

DID YOU MAKE ANY SIGNIFICANT CHANGES TO THE PORTFOLIO SINCE THE ANNUAL REPORT?

     Slowing sales growth has caused investors to shy away from restaurant
stocks, which has created some pretty compelling valuations relative to good
growth prospects. We've used this opportunity to build our position.

     As we mentioned earlier, utilities have enjoyed a nice rally because
investors recognized the attractive  valuations in this area at about the  same
time they were looking for safety in a volatile market. Because we had
overweighted positions in utilities while valuations were low, we took advantage
of the run-up to trim our position.

     Small Cap Value maintains significant positions in property and casualty
insurance companies and in the food and beverage industry.

THE FUND'S SUCCESSES HAVE NOT BEEN  LIMITED TO TRADITIONAL VALUE SECTORS.  CAN
YOU EXPLAIN HOW YOUR PROCESS  KEEPS THE WHOLE INVESTMENT LANDSCAPE OPEN TO YOU?

     Yes. We use a bottom-up approach, examining each company we consider
investing in individually, on its own merits. The starting point is finding
stocks that meet our initial valuation  criteria. We then dig deeper, winnowing
the universe to identify sound companies trading at a discount to fair value,
regardless of sector or industry. This bottom-up approach enables us to step
outside traditional value arenas --  railroads, steel companies, and cyclicals
-- and search for value opportunities in non-traditional sectors such as
software and medical products.

WHAT IS YOUR OUTLOOK FOR THIS APPROACH  TO INVESTING?

     Though investors have begun to  recognize the attractive pricing in the
small-cap value realm, we continue to see opportunities for the fund. We are
applying our investment process to build positions in inexpensively priced,
solid companies, which we believe will benefit our investors when these stocks
are discovered by the market.

Large Cap Value--Q&A
--------------------------------------------------------------------------------

[photo of Mark Mallon and Chuck Ritter]

     An interview with Mark Mallon and Chuck Ritter, portfolio managers on the
Large Cap Value investment team.

HOW DID LARGE CAP VALUE PERFORM  DURING THE SIX MONTHS ENDED  SEPTEMBER 30,
2000?

     Large Cap Value gained 4.14%, in line with its benchmark, the S&P 500/
BARRA Value Index, which also returned 4.14%. The S&P 500 Index, considered to
be representative of the broad market, declined 3.60%.

WHAT CONTRIBUTED TO LARGE CAP VALUE'S PERFORMANCE?

     Several factors played a role. First, we positioned Large Cap Value
conservatively, with smaller stakes in areas of the market, such as technology,
that proved the most volatile during the period.

     A second -- and significant -- factor was that the market was kind to value
stocks, particularly in the second half of the period. With the economy
appearing to slow, investor concerns about earnings intensified. Then, in the
third quarter, several well-known consumer products companies and leading
technology firms warned that earnings would be lower than expected. This news
sent money out of growth and technology stocks and into the types  of stocks
found in Large Cap Value's portfolio -- reasonably priced on  conservative
earnings expectations.

FINANCIAL STOCKS REPRESENTED THE FUND'S LARGEST SECTOR WEIGHTING AT THE END  OF
SEPTEMBER. WHAT WAS THE  ATTRACTION THERE?

     The financial sector is broad, encompassing banks, brokerages, credit card
firms, financial services firms and insurance providers. However, the group in
general has struggled in the wake of the Federal Reserve's series of interest
rate hikes, which were designed to moderate economic growth and head off
inflation. Higher rates reduce the margins between the rates lending
institutions pay depositors and those they charge for loans. As investors
shunned the group in lieu of faster-growing areas of the market, a number of
financial firms became very attractively valued. Later, as signs of slowing
growth emerged, the market became convinced that the Fed had reached or was
nearing the end of its rate-hike program, and financial stocks -- and bank
shares in particular -- rebounded smartly. With about a quarter of Large Cap
Value's assets in financials, the fund was well positioned to gain from this
shift in sentiment.

WERE THESE SOME OF THE STOCKS  THAT PROVED TO BE TOP PERFORMERS  DURING THE
PERIOD?

     Yes. For example, Washington Mutual, a thrift, and Household International,
a high-quality financial services company, were downtrodden for some time,
mostly due to investor concerns about how the companies might perform in a
rising rate environment. As rates stabilized, though, confidence in the
companies' prospects grew and their share prices responded accordingly.

     Within the financial sector, the fund also profited from its investments in
property and casualty insurance

Large Cap Value--Q&A
--------------------------------------------------------------------------------

                                                                    (Continued)

companies. One top contributor was Allstate. Like other insurers, Allstate
was hurt by intensive rate competition and the costs of spring storms in the
Midwest. As insurance rates began to increase during the third quarter, however,
the company rebounded strongly.

WHICH OTHER STOCKS CONTRIBUTED TO PERFORMANCE?

     Two top contributors we'd like to highlight are Boeing, the world's biggest
maker of jet planes, and drug giant Eli Lilly. Last year, investors appeared
concerned that orders for Boeing's  airplanes would decline. Instead, with the
global economy on the rebound, Boeing's orders have improved, along with its
production outlook for the next few years. In addition, Boeing has
significantly raised the productivity of its assembly lines, resulting in more
profit per plane.

     Our investment in Lilly reflects our strategy of investing in high-quality
growth companies when their share prices become cheap relative to their
long-term prospects. Lilly, a large  pharmaceutical company, suffered  last year
from concerns about patent expirations among its key products. However, this
firm, a leader in its  industry, has a strong research effort. The stock soared
this year in response to news about promising developments in its research
laboratories, and we sold at a very nice gain.


WHAT ABOUT DISAPPOINTMENTS?

     Telecommunications companies detracted most from performance during the
period. This industry has become increasingly competitive, and has also
struggled in recent months in sympathy with the downturn in technology-oriented
firms. Telephone service providers have had the toughest time. The biggest
detractors in this group were Sprint and WorldCom, whose problems were
compounded when their proposed merger was disallowed by federal regulators on
the belief that the combined organization would have unfair market advantages
and reduce competition. AT&T also hurt performance. These firms struggled with
weakness in consumer long-distance pricing and the developing perception that
the voice long-distance business may be in a serious decline.

     Another holding, Computer Associates, also slowed our progress during the
quarter, but we believe  the company remains a solid value opportunity. This
business, which  sells mainframe software, saw revenues slow as IBM, the leader
in mainframes, embarked upon a major upgrade  cycle. Because we believe Computer
Associates' current troubles are transitory, we added to the fund's position.

ENERGY STOCKS REPRESENT A SUBSTANTIAL PORTION OF INVESTMENTS. WHAT ATTRACTED
YOU TO THIS SECTOR?

     Energy proved to be a fruitful sector for the fund, as rising energy prices
lifted most stocks in that realm. Although we've done well in this group, we
have remained relatively cautious and, in fact, are underweight compared to the
index. We generally believe that many companies have reached their peak in
earnings and no longer trade at the bargain prices we look for. Our investments
remain focused among integrated oil firms, such as Exxon/Mobil and Royal Dutch
Petroleum. These firms offer a chance to participate in the sector's  success,
and also offer a measure of  stability. We have avoided some of the more richly
valued energy service companies whose earnings are dependent on even higher
energy prices.

WHAT ABOUT CONSUMER CYCLICALS?

     This sector is at the opposite end of the spectrum from energy. While many
energy firms' prices reflect an increasingly optimistic outlook, many consumer
cyclical companies are currently valued as if a recession is imminent. While
history tells us that a recession is inevitable at some point, we do not believe
it's right around the corner. For that reason, we've taken substantial positions
in economically sensitive  sectors, such as consumer cyclicals and industrials,
where stock prices appear to have been driven down to levels that are
interesting to us. We feel these areas offer good value and opportunities.

WHAT IS YOUR OUTLOOK FOR THE REST OF 2000 AND THE BEGINNING OF 2001?

     Over the short term, we anticipate a relatively benign interest-rate
environment. We also expect that economic growth will continue to be healthy,
but will proceed at a slower rate than the pace it has set over the past few
years. As a result, we're not positioning the fund for an imminent economic
downturn. Instead, we continue to look for fundamentally sound firms that appear
to be undervalued. Many Old Economy stocks came down severely over the past
year, and the marketplace is offering a diverse menu of value opportunities.

     As far as the future of value-oriented investing is concerned, we've seen
indications in recent months that investors have begun to pay attention to the
price they're willing to pay for a company's business prospects. This is a
profound reversal in sentiment from 1999 and early 2000, when price momentum,
rather than relative value or fundamentals, drove the market. This development
is an encouraging sign for investors pursuing a value strategy.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as  securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results  in the fund's NET
ASSETS. For each class of shares, the net assets divided by shares outstanding
is the share price, or NET ASSET VALUE PER SHARE. This statement also breaks
down the fund's net assets into capital (shareholder investments) and
performance (investment income and gains/losses).

Notes to Financial Statements
--------------------------------------------------------------------------------

SEPTEMBER 30, 2000 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Capital Portfolios, Inc. (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. Value Fund (Value), Equity Income Fund
(Equity Income), Small Cap Value Fund (Small Cap Value), and Large Cap Value
Fund (Large Cap Value) (the funds) are four of the six funds issued by the
corporation. The funds are diversified under the 1940 Act. The investment
objective of Value, Small Cap Value and Large Cap Value is long-term capital
growth. The production of income is a secondary objective. Value, Small Cap
Value and Large Cap Value seek to achieve their investment objective by
primarily investing in equity securities of companies that management believes
to be undervalued at the time of purchase. Small Cap Value invests in companies
with smaller market capitalization, Value invests in companies with medium to
large market capitalization, and Large Cap Value invests in companies with
larger market capitalization. The investment objective of Equity Income is the
production of current income through investments in income-producing equity
securities. Capital appreciation is a secondary objective. The following
significant accounting policies are in accordance with generally accepted
accounting principles; these policies may require the use of estimates by fund
management.

    MULTIPLE CLASS -- The funds are authorized to issue three classes of shares:
the Investor Class, the Advisor Class, and the Institutional Class. The three
classes of shares differ principally in their respective shareholder servicing
and distribution expenses and arrangements. All shares of each fund represent an
equal pro rata interest in the assets of the class to which such shares belong,
and have identical voting, dividend, liquidation and other rights and the same
terms and conditions, except for class specific expenses and exclusive rights to
vote on matters affecting only individual classes. Sale of the Advisor Class and
Institutional Class had not commenced for Large Cap Value as of September 30,
2000.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no last sales price is available.
Securities traded over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price, depending on local convention or regulation. Debt securities not
traded on a principal securities exchange are valued through a commercial
pricing service or at the mean of the most recent bid and asked prices. When
valuations are not readily available, securities are valued at fair value as
determined in accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date. Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    FUTURES CONTRACTS -- The funds may enter into stock index futures contracts
in order to manage each fund's exposure to changes in market conditions. One of
the risks of entering into futures contracts is the possibility that the change
in value of the contract may not correlate with the changes in value of the
underlying securities. Upon entering into a futures contract, each fund is
required to deposit either cash or securities in an amount equal to a certain
percentage of the contract value (initial margin). Subsequent payments
(variation margin) are made or received daily, in cash, by the funds. The
variation margin is equal to the daily change in the contract value and is
recorded as unrealized gains and losses. The fund recognizes a realized gain or
loss when the contract is closed or expires. Net realized and unrealized gains
or losses occurring during the holding period of futures contracts are a
component of realized gain (loss) on investments and unrealized appreciation
(depreciation) on investments, respectively.

    REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with
institutions that the fund's investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. Each fund requires that the collateral, represented by securities,
received in a repurchase transaction be transferred to the custodian in a manner
sufficient to enable each fund to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure the value, including accrued interest, of the
securities under each repurchase agreement is equal to or greater than amounts
owed to each fund under each repurchase agreement.

    JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, each fund, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid quarterly. Distributions from net realized gains are generally declared
and paid annually.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    At March 31, 2000, Large Cap Value had accumulated net realized capital loss
carryovers for federal income tax purposes of $4,788 (expiring in 2008) which
may be used to offset future taxable gains.

    For the five month period ended March 31, 2000, Value, Equity Income, and
Small Cap Value incurred net capital losses of $173,002,368, $25,386,721, and
$73,910, respectively. The funds have elected to treat such losses as having
been incurred in the following fiscal year.

Notes to Financial Statements
--------------------------------------------------------------------------------

                                                                    (Continued)

--------------------------------------------------------------------------------
2. TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the funds with investment advisory and management services
in exchange for a single, unified management fee per class. The Agreement
provides that all expenses of the funds, except brokerage commissions, taxes,
interest, expenses of those directors who are not considered "interested
persons" as defined in the 1940 Act (including counsel fees) and extraordinary
expenses, will be paid by ACIM. The fee is computed daily and paid monthly based
on each fund's class average daily closing net assets during the previous month.
Following are the management fee schedules for the funds:

                  Value     Equity      Small Cap           Large Cap
                            Income        Value               Value
Investor          1.00%     1.00%         1.25%           0.70% to 0.90%
Advisor           0.75%     0.75%         1.00%           0.45% to 0.65%
Institutional     0.80%     0.80%         1.05%           0.50% to 0.70%

    The management fee for Large Cap Value varies depending on fund asset
levels. As fund assets increase, the fee applied decreases. For the period ended
September 30, 2000, the effective annual Investor Class management fee for Large
Cap Value was 0.90%.

    The Board of Directors has adopted a Master Distribution and Shareholder
Services Plan (the plan) for the Advisor Class, pursuant to Rule 12b-1 of the
1940 Act. The plan provides that the funds will pay ACIM an annual distribution
fee equal to 0.25% and service fee equal to 0.25%. The fees are computed daily
and paid monthly based on the Advisor Class's average daily closing net assets
during the previous month. The distribution fee provides compensation for
distribution expenses incurred in connection with distributing shares of the
Advisor Class including, but not limited to, payments to brokers, dealers, and
financial institutions that have entered into sales agreements with respect to
shares of the funds. The service fee provides compensation for shareholder and
administrative  services rendered by ACIM, its affiliates or independent third
party providers. Fees incurred under the plan during the six  month period ended
were $164,102, $50,194, and $3,508 for Value, Equity Income, and Small Cap
Value, respectively.

    Certain officers and directors of the corporation are also  officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, the
distributor of the corporation, American Century Service, Inc., and the
corporation's transfer agent, American Century Services Corporation.

This table itemizes investment results and distributions on a per-share basis to
illustrate share price changes for each of the last five fiscal years (or less,
if the share class is not five years old). It also includes several key
statistics for each reporting period, including TOTAL RETURN, INCOME RATIO (net
investment income as a percentage of average net assets), EXPENSE RATIO
(operating expenses as a percentage of average net assets), and PORTFOLIO
TURNOVER (a gauge of the fund's trading activity).

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Three classes of shares are authorized for sale by the funds: Investor
Class, Advisor Class and Institutional Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares is 0.25% higher than the total expense ratio of the Investor Class
shares.

    INSTITUTIONAL CLASS shares are available to endowments, foundations, defined
benefit pension plans or  financial intermediaries serving these investors. This
class recognizes the relatively lower cost of serving institutional customers
and others who invest at least $5 million in an American Century fund or at
least $10 million in multiple funds. In recognition of the larger investments
and account balances and comparatively lower transaction costs, the total
expense ratio of the Institutional Class shares is 0.20% less than the total
expense ratio of the Investor Class shares.

    All classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.

RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke  your election at any time by sending a written notice
to us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY & POLICIES

American Century offers 15 growth and income funds including domestic equity,
balanced, asset allocation, and specialty. Value, Equity Income, Small Cap
Value, and Large Cap Value are general equity funds managed to provide growth
over time with less volatility than more aggressive growth funds. Stock
purchases are based on a company-by-company analysis to determine whether a
stock is trading below what the fund management team  considers fair value.
Equity Income may buy stocks that are trading at fair value if the stock pays a
generous dividend. In all four funds, broad diversification across many
industries is stressed to prevent the performance of one sector from dominating
fund returns.

     AMERICAN CENTURY VALUE invests in the equity securities of seasoned,
established businesses that the management team believes are temporarily
undervalued. This is determined by comparing a stock's share price with key
financial measures, including earnings, book value, cash flow and dividends. If
the stock's price relative to these measures is low and the company's balance
sheet is solid, its securities are candidates for purchase. The management team
may look secondarily for income.

     AMERICAN CENTURY EQUITY INCOME purchases the securities of seasoned
companies that pay steady income, with the goal of providing shareholders a
higher yield than the aggregate yield of the stocks making up the S&P 500. The
team may secondarily search out stocks whose share prices are undervalued or
fairly valued. Under normal circumstances, the fund can be expected to have less
share-price volatility than American Century Value.

     AMERICAN CENTURY SMALL CAP VALUE focuses on the stocks of small companies
with market capitalizations of less than the largest company in the S&P SmallCap
600/BARRA Value Index. Historically, small-cap stocks have been more volatile
than the stocks of larger, more established companies. The fund seeks capital
appreciation over time by investing in common stocks that the management team
believes to be undervalued. Income is a secondary objective.

     AMERICAN CENTURY LARGE CAP VALUE seeks long-term capital growth with income
as a secondary objective. The fund invests primarily in equity securities of
large well-established companies that have good cash flow and reasonable growth
prospects, and appear to be undervalued at the time of purchase. It uses a
relative value approach, which considers the price for a  company's fundamentals
within the context of its historical relationship to the overall market.

COMPARATIVE INDICES

     The following indices are used in the report to serve as fund performance
comparisons. They are not investment products available for purchase.

     THE S&P 500 INDEX is a capitalization- weighted index of the stocks of 500
publicly  traded U.S. companies that are considered to be leading firms in
leading industries. Created by Standard & Poor's, it is intended to be a broad
measure of U.S. stock market performance.

     THE S&P 500/BARRA VALUE INDEX is a  capitalization-weighted index
consisting of S&P 500 stocks that have lower price-to-book ratios and, in
general, share other characteristics  associated with value-style stocks.

     THE LIPPER EQUITY INCOME FUND INDEX is a non-weighted index of the 30
largest equity income mutual funds. Lipper, Inc., is an independent mutual fund
ranking service.

     THE LIPPER MULTI-CAP VALUE INDEX consists of the largest funds tracked by
Lipper Inc., that seek long-term growth of capital by investing  in companies of
all capitalization sizes that are considered to be undervalued relative to a
major unmanaged stock index based on price-to- current earnings, book value,
asset value, or  other factors.

     THE S&P SMALLCAP 600/BARRA VALUE INDEX is a capitalization-weighted index
consisting of S&P SmallCap 600 stocks that have lower price-to-book ratios. The
S&P SmallCap 600 Index consists of 600 domestic stocks chosen  for market size,
liquidity, and industry group  representation.

Glossary
--------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 39-48.

INVESTMENT TERMS

* MEDIAN MARKET CAPITALIZATION-- market capitalization (market cap) is the total
value of a company's stock and is calculated by multiplying the number of
outstanding common shares by the current share price. The company whose market
cap is in the middle of the portfolio is the median market cap. Half the
companies in the portfolio have values greater than the median, and half have
values that are less. If there is an even number of companies, then the median
is the average of the two companies in the middle.

* WEIGHTED AVERAGE MARKET CAPITALIZATION-- average market capitalization
represents the average value of the companies held in a portfolio. When that
figure is weighted, the impact of each company's capitalization on the overall
average is proportional to the total market value of its shares.

* NUMBER OF COMPANIES-- the number of different companies held by a fund on a
given date.

* PORTFOLIO TURNOVER-- the percentage of a fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

* PRICE/BOOK RATIO-- a stock value measurement calculated by dividing a
company's stock price by its book value per share, with the result expressed as
a multiple instead of as a percentage. (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)

* PRICE/EARNINGS (P/E) RATIO-- a stock value measurement calculated by dividing
a company's stock price by its earnings per share, with the result expressed as
a multiple instead of as a percentage. (Earnings per share is calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)
When this figure is weighted, the impact of each company's P/E ratio is in
proportion to the percentage of the fund that the company represents.

* DIVIDEND YIELD -- a stock value measurement calculated by dividing the
12-month dividend per share by the current price of the share. Dividend yields
for each of the stocks held in the fund are then weighted according to their
proportion of fund assets and the resulting figures are averaged to arrive at
the fund's dividend yield.

TYPES OF STOCKS

* BLUE CHIP STOCKS-- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* CYCLICAL STOCKS-- generally considered to be stocks whose price and earnings
fluctuations tend to follow the ups and downs of the business cycle. Examples
include the stocks of automobile manufacturers, steel producers and textile
operators.

* GROWTH STOCKS-- stocks of companies that have experienced above-average
earnings growth and are expected to continue such growth. These stocks often
sell at high P/E ratios. Examples can include the stocks of high-tech,
healthcare and consumer staple companies.

* LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $9.9 billion. This is Lipper's market capitalization breakpoint as of
September 30, 2000, although it may be subject to change based on market
fluctuations. The Dow Jones Industrial Average and the S&P 500 Index generally
consist of stocks in this range.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
between $2.3 billion and $9.9 billion. This is Lipper's market capitalization
breakpoint as of September 30, 2000, although it may be subject to change based
on market fluctuations. The S&P 400 Index and Russell 2500 Index generally
consist of stocks in this range.

* SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of less
than $2.3 billion. This is Lipper's market capitalization breakpoint as of
September 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 600 Index and the Russell 2000 Index generally consist of
stocks in this range.

* VALUE STOCKS-- generally considered to be stocks that are purchased because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

FUND CLASSIFICATIONS

    Please be aware that a fund's category may change over time. Therefore, it
is important that you read the fund's prospectus or fund profile carefully
before investing to ensure its objectives, policies and risk potential are
consistent with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.


* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with correspondingly high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price-fluctuation risk.

with your needs. For a definition of fund categories, see the Glossary.

* While listed within the Income investment objective, the Target funds do not
  pay current dividend income. Income  dividends are distributed once a year in
  December. The Target funds are listed in all three risk categories due to the
  dramatic price volatility investors may experience during certain market
  conditions. If held to their target dates,  however, they can offer a
  conservative, dependable way to invest for a specific time horizon. Target
  2000 will close on December 15, 2000. The fund closed to new investors on
  10/1/2000, and will no longer accept investments from current shareholders
  beginning 11/01/2000.

     The six months covered by this report saw investors begin to look beyond
technology stocks for ways to diversify and broaden their holdings. Many of them
found a previously out-of-favor sector that offered attractive valuations and
stability -- real estate investment trusts (REITs).

     Those two qualities alone were significant contributions during one of the
most volatile periods in the market's history. But REITs also provided investors
with solid earnings growth and the opportunity to take part in a neglected
sector with strong fundamentals. That shift in investors' focus, along with
intelligent stock selections, resulted in superior performance by American
Century Real Estate.

     Turning to corporate matters, Chase Manhattan Corp. recently announced
plans to acquire J.P. Morgan & Co., a substantial minority shareholder in
American Century Companies, Inc. since 1998. If the transaction is completed as
expected, J.P. Morgan Chase, the new enterprise, will own the shares of American
Century currently held by Morgan. Corporate control of American Century is not
affected by this transaction. We will be exploring ways to partner with J.P.
Morgan Chase for the benefit of fund shareholders.

     In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to share the chairman of
the board position and named American Century President William M. Lyons chief
executive officer, giving him ultimate management responsibility for the entire
company.

     These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue additional worthwhile endeavors. For example, Jim Stowers III will focus
more on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next generation of portfolio management
technologies). However, his first priority will be continuing involvement on the
investment teams responsible for the Ultra and Veedot funds.

     We appreciate your continued confidence in American Century.

Sincerely,

/signature/                             /signature/

Report Highlights
--------------------------------------------------------------------------------

MARKET PERSPECTIVE

*  After several years of focusing almost exclusively on technology stocks,
   investors broadened their holdings during the six months ended September
   30, 2000, boosting real estate investment trusts (REITs) and other
   underappreciated sectors of the market.

*  Many investors were drawn to the attractive valuations and stability of REITs
   as an alternative to the volatility and rich prices of most tech stocks.

*  Another attraction was the favorable fundamentals of the REIT market. Real
   estate demand has been outstripping supply, leading to steady earnings
   growth for REITs. While the Nasdaq Composite Index declined in four of the
   six months during the period, the Morgan Stanley REIT Index advanced in
   each month.

*  Every industry within the REIT sector turned in solid returns during the
   period. In particular, office and industrial REITs benefited from declining
   vacancies, rising rents, and a lag in the construction of new space.

ACRE

*  The American Century Real Estate Fund (ACRE) posted a return of 20.05% during
   the six months ended September 30. ACRE outperformed the Morgan Stanley
   REIT Index, which gained 18.99%. The fund also surpassed the 19.37% average
   return of the real estate funds tracked by Lipper Inc. The S&P 500 declined
   3.60% during the period.

*  ACRE focused on well-managed REITs that operate properties in tight markets
   and high-growth regions. These companies tended to outperform their weaker
   peers. The fund also benefited from overweight positions in office and
   industrial REITs, which were the top two performers in the REIT market.
   Merger and acquisition activity boosted the performance and long-term
   strategies of several fund holdings.

*  The long-term performance of the REIT market is driven by the attractive
   income and steady growth of the underlying properties. While the sector's
   performance so far in 2000 has been strong, it still hasn't made up for two
   years of negative returns. Nonetheless, the fundamentals of the real estate
   market remain attractive, and REIT earnings continue to grow at a healthy
   pace.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------

funds at American Century

PERFORMANCE OVERVIEW

     The winds of change blew through the U.S. stock market during the six
months ended September 30, 2000. After posting returns of 20% or more for the
past five years, the broader market declined as signs of a slowing global
economy led to concerns about corporate profits. In contrast, real estate
investment trusts (REITs), which invest in shopping centers, apartments and
other rental property, produced very strong returns after more than two years of
disappointing performance (see the table at right).

AN ALTERNATIVE TO TECHNOLOGY

     The REIT market has been in a rut since late 1997, when investors began
focusing their attention almost exclusively on technology stocks. Investors
embraced the potential of electronic commerce and bid up the stock prices of
"dot-coms" and other Internet- and computer-related companies. As technology
stocks soared throughout 1998 and 1999, REITs were largely ignored, posting
negative returns.

     However, this year brought a sharp reversal in investor sentiment. After
the tech sector peaked in March and began its precipitous decline, investors
began to question sustainability and profitability in the technology sector.
Many began to seek out opportunities in undervalued, underappreciated sectors of
the market, such as REITs.

     The graph at right shows the degree to which REITs and technology stocks
moved in opposite directions during the past six months. The Nasdaq Composite
Index, which is dominated by tech stocks, fell in four of the six months, while
the Morgan Stanley REIT Index rose in each of those months.

     Here's another illustrative statistic -- according to a study done by J.P.
Morgan & Co., the Nasdaq and the Morgan Stanley REIT Index have had a
correlation of approximately -0.6 this year. A correlation of 1.0 means they
move an equal amount in the same direction; a correlation of -1.0 means they
move an equal amount in the opposite direction.

FUNDAMENTALLY STRONG

     Investors returned to the REIT sector in part because it had been beaten
down, but they were also attracted by the favorable fundamentals in the property
market.

     Demand has remained consistently strong, especially for commercial real
estate, while supply has grown increasingly constrained. Construction of new
space is under way, but it hasn't been enough to keep up with demand. As a
result, rents have risen steadily, fueling healthy earnings growth for many
REITs.

SECTOR PERFORMANCE

     Every industry within the REIT sector produced solid returns during the
period. Industrial and office companies were the top performers. Rent growth has
been especially high among office buildings and industrial complexes, thanks to
low vacancy rates. Again, supply of new space isn't meeting demand.

BUT THEY WERE ALSO ATTRACTED BY THE FAVORABLE FUNDAMENTALS IN THE PROPERTY
MARKET."

ACRE--Q&A
--------------------------------------------------------------------------------

[photo of Daniel O'Connor]

     An interview with Daniel O'Connor, a portfolio manager on the American
Century Real Estate (ACRE) fund investment team. Mr. O'Connor works for J.P.
Morgan Investment Management, which took over day-to-day management
responsibilities of ACRE from RREEF America on January 1, 2000.

HOW DID ACRE PERFORM DURING THE SIX MONTHS ENDED SEPTEMBER 30, 2000?

     The fund returned 20.05%, reflecting the strong recovery of real estate
investment trusts (REITs).* This performance beat both the 18.99% return of its
benchmark, the Morgan Stanley REIT Index, and the 19.37% average return of the
real estate funds tracked by Lipper Inc. (See the previous page for additional
fund performance comparisons.) The S&P 500, a broad stock market measure, fell
3.60%.

WHY DID THE FUND PERFORM SO WELL COMPARED WITH ITS BENCHMARK AND PEERS?

     The most important factor was probably our decision to overweight office
and industrial REITs compared with the index. These two areas of the market were
the best performers during the six-month period, and they made up more than a
third of the fund's portfolio.

     We've been attracted to office REITs -- and this applies to industrial
REITs as well -- because they have the strongest fundamentals in the real estate
sector. Low vacancy rates, consistently strong demand for office space, and a
limited amount of new construction has led to healthy rent increases, which, in
turn, have produced spectacular earnings growth for office REITs.

CAN YOU GIVE SOME EXAMPLES OF YOUR FAVORITE OFFICE AND INDUSTRIAL HOLDINGS?

     One of ACRE's better performers was Arden Realty, an office REIT based in
Southern California. The company's properties benefited from declining vacancies
and increasing rental rates. In addition, Arden is finally getting recognition
for its exposure to the Los Angeles-San Diego area, one of the strongest office
markets in the country. Arden shares were up more than 30% during the six-month
period.

     The fund also benefited from positions in Spieker Properties (up 33%) and
Mission West Properties (up 67%), two office REITs with sizable property
portfolios in Silicon Valley. The Valley is one of the strongest markets in the
country -- earlier this year, property owners were seeing rental rate increases
in excess of 50% on new leases.

     Among industrial REITs, Prologis (up 27%) was the fund's best performer and
a top-10 holding. Low vacancies in its property portfolio, combined with a
high-yielding development pipeline, boosted the company's operating profits.
Prologis, and others in that field, rent buildings to light manufacturing
businesses.

THE FUND'S LARGEST HOLDING IS ANOTHER OFFICE REIT, EQUITY OFFICE PROPERTIES,
WHICH MAKES UP NEARLY 10% OF THE PORTFOLIO. WHY SUCH A LARGE POSITION?

     Equity Office is the largest REIT in the nation, partly because of its
recently completed acquisition of Cornerstone

ACRE--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

Properties, another big office REIT. The combined company now constitutes
more than 7% of the Morgan Stanley REIT Index.

     We hold a larger percentage because we think the long-term outlook for the
company is excellent. We expect greater profit growth as Equity Office leverages
its dominant position in a number of high-growth markets. In addition, the
acquisition of Cornerstone has provided exposure to the strong Northern
California market, and the embedded rental increases in this area should add to
the company's bottom line.

WERE THERE ANY OTHER IMPORTANT MERGERS IN THE REIT MARKET?

     A couple of REITs were bought by other companies and taken private. The
most significant of these was the acquisition of Urban Shopping Centers, a
high-quality shopping mall REIT, by Rodamco, a Dutch real estate company.
Rodamco paid a substantial premium for Urban's properties, and that drove
Urban's share price up by nearly 70%. ACRE held an overweight position in
Urban.

     Another important acquisition was one that never took place. Mack-Cali
Realty, an office REIT, agreed to acquire Prentiss Properties in June. The move
made little economic sense -- our view was that Mack-Cali was overpaying for a
company that would dilute its property portfolio's exposure to tightly
constrained markets. The market registered its protest by punishing Mack-Cali's
share price, and by September, the two companies had called off the deal.

     When the merger was originally announced, we shifted from an overweight in
Mack-Cali to an overweight in Prentiss, figuring that Prentiss would benefit
whether the merger happened or not. This proved to be true, and we reduced our
stake in Prentiss after the deal was abandoned.

ACRE HAD PLENTY OF SUCCESSES DURING THE PERIOD, BUT WAS THERE ANY BAD NEWS IN
THE PORTFOLIO?

     With so few REITs posting negative returns, the main weaknesses in the
portfolio were missed opportunities -- underweights that performed well.

     A good example is Archstone Community Properties, a residential REIT that
returned 27% during the period. We'd been avoiding Archstone because many of its
properties were in weak, overbuilt markets. However, Archstone has been
repositioning its property portfolio into more desirable markets, and the
company also agreed to buy back some of its shares.

     Although we added Archstone to the fund late in the period, we missed out
on just about all of its gains.

HAVE THERE BEEN ANY NEW TRENDS DEVELOPING IN THE REIT MARKET?

     We're beginning to see a few firms issue new equity. In the mid-1990s,
REITs raised the funds needed to buy properties by issuing new shares. But when
REITs fell out of favor in 1998, that source of funding dried up, so companies
stopped issuing equity. Instead, they started selling properties that were
unprofitable or in weak markets and used the proceeds to buy new, more
attractive properties.

     In the past few months, however, Kimco Realty issued 1.8 million new
shares, and Equity Office Properties issued $300 million in convertible
securities. Although the sizes of these offerings are relatively small, the
market's tolerance for equity issuance --

even if only by a select group of premier companies--is a positive sign.

     That said, we don't expect a huge rash of new equity issuance in the months
ahead. REITs appear to be showing remarkable restraint given the sector's
previous excesses. Most companies have become cautious in their use of capital
markets, and they continue to recycle their property portfolios into more
promising projects rather than tap the equity markets.

DO YOU THINK REITS CAN MAINTAIN THEIR STRONG PERFORMANCE GOING FORWARD?

     Probably not at the same pace, but our outlook is still positive. Even
though REITs have done well this year, it's really been a recovery from the
excessive pessimism that produced the bear market of 1998 and 1999. If you look
at the three-year returns of the fund and Morgan Stanley REIT Index, you can see
that they're slightly negative, which means this year's healthy returns haven't
yet made up for the declines of the previous two years.

     As a result, we still think the REIT market is fundamentally attractive.
Supply remains constrained in most markets and property types. And while REIT
performance has been essentially flat to slightly negative over the past three
years, funds from operations (FFO) -- the REIT equivalent of earnings -- have
averaged double-digit annual growth during that time.

     We're also seeing a quality distinction in the REIT market. Well-managed
companies operating in tight markets and high-growth regions have been
outperforming their weaker peers. We expect this trend to continue as investors
cautiously return to the market.

     However, the REIT market doesn't operate in a vacuum -- its performance may
be affected by upheaval in the broader equity market. Cash flows into REITs so
far this year have mirrored flows out of the technology sector, and we may see
this effect continue in the coming months.

     It's important to remember, though, that the long-term performance of the
REIT market is driven by the underlying properties. Except for a few rare
moments, core real estate returns reflect a mix of attractive income -- REITs
have a current yield of 7% on average -- supported by steady growth.

HOW WILL THIS OUTLOOK AFFECT YOUR PLANS FOR ACRE IN THE COMING MONTHS?

     Our focus will remain on quality firms that are well-positioned in strong
markets. We still like the outlook for office and industrial companies. In
recent months, we've seen increased development in the office sector, with the
bulk of new construction concentrated in tight markets, such as Boston, New
York, Portland, and San Francisco. Overall, though, demand is still outstripping
supply, and the low vacancy rates should be positive for rent growth.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other payables) as of the last day of the reporting period.
Subtracting the liabilities from the assets results in the fund's NET ASSETS.
For each class of shares, the net assets divided by shares outstanding is the
share price, or NET ASSET VALUE PER SHARE. This statement also breaks down the
fund's net assets into capital (shareholder investments) and performance
(investment income and gains/losses).

Notes to Financial Statements
--------------------------------------------------------------------------------

SEPTEMBER 30, 2000 (UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Capital Portfolios, Inc. (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. Real Estate Fund (the fund) is one of
the six funds issued by the corporation. The fund is non-diversified under the
1940 Act. The fund's investment objective is long-term capital appreciation with
income as a secondary objective. The fund seeks to achieve its objective by
investing primarily in securities issued by real estate investment trusts and in
the securities of companies which are principally engaged in the real estate
industry. There are certain additional risks involved in investing in the fund
as compared to investing in a more diversified portfolio of investments. The
fund may be subject to certain risks similar to those associated with direct
ownership of real estate including but not limited to: local or regional
economic conditions, changes in zoning laws, credit risk, and interest rate
risk. The following significant accounting policies are in accordance with
generally accepted accounting principles; these policies may require the use of
estimates by fund management.

    MULTIPLE CLASS -- The fund is authorized to issue three classes of shares:
the Investor Class, the Advisor Class, and the Institutional Class. The three
classes of shares differ principally in their respective shareholder servicing
and distribution expenses and arrangements. All shares of the fund represent an
equal pro rata interest in the assets of the class to which such shares belong,
and have identical voting, dividend, liquidation and other rights and the same
terms and conditions, except for class specific expenses and exclusive rights to
vote on matters affecting only individual classes.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no last sales price is available.
Securities traded over-the-counter are valued at the mean of the latest bid and
asked prices or at the last reported sales price. When valuations are not
readily available, securities are valued at fair value as determined in
accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal and state income tax purposes.

    INVESTMENT INCOME -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date. Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with
institutions that the fund's investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. The fund requires that the collateral, represented by securities, received
in a repurchase transaction be transferred to the custodian in a manner
sufficient to enable the fund to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure that the value, including accrued interest, of
the securities under each repurchase agreement is equal to or greater than
amounts owed to the fund under each repurchase agreement.

    JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME TAX STATUS -- It is the policy of the fund to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid quarterly. Distributions from net realized gains are declared and paid
annually.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    At March 31, 2000 the fund had accumulated net realized capital loss
carryovers for federal income tax purposes of $17,682,932 (expiring in 2007
through 2008) which may be used to offset future taxable gains.

    For the five month period ended March 31, 2000, the fund incurred net
capital losses of $17,337,181. The fund has elected to treat such losses as
having been incurred in the following fiscal year.

2. TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the fund with investment advisory and management services in
exchange for a single, unified management fee per class. The Agreement provides
that all expenses of the fund, except brokerage commissions, taxes, interest,
expenses of those directors who are not considered "interested persons" as
defined in the 1940 Act (including counsel fees) and extraordinary expenses,
will be paid by ACIM. The fee is computed daily and paid monthly based on the
fund's class average daily closing net assets during the previous month.

  The annual management fee for each class of Real Estate is as follows:

                              INVESTOR       ADVISOR       INSTITUTIONAL

Over $100,000,000 ...........  1.15%          0.90%            0.95%

    ACIM has entered into a Subadvisory Agreement with J.P. Morgan Investment
Management (JPMIM) on behalf of the fund. The subadvisor makes investment
decisions for the fund in accordance with the fund's investment objectives,
policies, and restrictions under the supervision of ACIM and the Board of
Directors. ACIM pays all costs associated with retaining JPMIM as the subadvisor
of the fund. JPMIM is a wholly owned subsidiary of J.P. Morgan & Co.
Incorporated, an equity investor in American Century Companies, Inc.

    The Board of Directors has adopted a Master Distribution and Shareholder
Services Plan (the plan) for the Advisor Class, pursuant to Rule 12b-1 of the
1940 Act. The plan provides that the fund will pay ACIM an annual distribution
fee equal to 0.25% and service fee equal to 0.25%. The fees are computed daily
and paid monthly based on the Advisor Class's average daily closing net assets
during the previous month. The distribution fee provides compensation for
distribution expenses incurred by financial intermediaries in connection with
distributing shares of the Advisor Class including, but not limited to, payments
to brokers, dealers, and financial institutions that have entered into sales
agreements with respect to shares of the fund. The service fee provides
compensation for shareholder and administrative services rendered by ACIM, its
affiliates or independent third party providers. Fees incurred under the plan
for the six month period ended September 30, 2000 were $16,040.

    Certain officers and directors of the corporation are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, the
distributor of the corporation, American Century Services, Inc., and the
corporation's transfer agent, American Century Services Corporation.

--------------------------------------------------------------------------------
3. INVESTMENT TRANSACTIONS

    Purchases and sales of investment securities, excluding short-term
investments, for the six month period ended September 30, 2000, were
$110,124,674 and $130,487,950, respectively.

    As of September 30, 2000, accumulated net unrealized appreciation was
$9,213,654, based on the aggregate cost of investments for federal income tax
purposes of $81,149,914, which consisted of unrealized appreciation of
$11,341,212 and unrealized depreciation of $2,127,558.

This table itemizes investment results and distributions on a per-share basis to
illustrate share price changes for each of the last five fiscal years (or less,
if the share class is not five years old). It also includes several key
statistics for each reporting period, including TOTAL RETURN, INCOME RATIO (net
income as a percentage of average net assets), EXPENSE RATIO (operating expenses
as a percentage of average net assets), and PORTFOLIO TURNOVER (a gauge of the
fund's trading activity).

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Three classes of shares are authorized for sale by the fund: Investor Class,
Advisor Class and Institutional Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares is 0.25% higher than the total expense ratio of the Investor Class
shares.

    INSTITUTIONAL CLASS shares are available to endowments, foundations, defined
benefit pension plans or financial intermediaries serving these investors. This
class recognizes the relatively lower cost of serving institutional customers
and others who invest at least $5 million in an American Century fund or at
least $10 million in multiple funds. In recognition of the larger investments
and account balances and comparatively lower transaction costs, the total
expense ratio of the Institutional Class shares is 0.20% less than the total
expense ratio of the Investor Class shares.

    All classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.

RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers 15 growth and income funds including domestic
equity, balanced, asset allocation, and specialty. Specialty equity funds
concentrate their holdings in specific industries or sectors of the stock
market. These funds typically respond differently than general equity funds to
changing market or economic conditions. The funds are managed to provide a broad
representation of their respective industries.

     AMERICAN CENTURY REAL ESTATE FUND'S primary investment objective is
long-term capital appreciation, with income as a secondary objective.

     ACRE typically invests at least 80% of its assets in the equity securities
of real estate investment trusts (REITs) and other companies engaged in the real
estate industry. The fund's management team evaluates potential investments
based on cash flow, property types, and exposure to growing property markets.

     Real estate investing involves inherent risks, including interest rate
fluctuations, credit risk, and the impact of changing economic conditions. In
addition, by focusing on a specific market sector, the fund may experience
greater volatility than do funds with a broader investment strategy. The fund is
not intended to serve as a complete investment program by itself.

FUND MANAGEMENT TEAM

     RREEF America LLC, and its predecessor company, served as the fund's
investment subadvisor from its inception until it resigned on December 31, 1999.
In connection with its resignation, RREEF informed ACIM and the fund that RREEF
had entered into an arrangement with J.P. Morgan Investment Management Inc.
(JPMIM), providing for RREEF's resignation as subadvisor and the purchase by
JPMIM from RREEF of certain books and records relating to the fund. JPMIM began
subadvising the fund on January 1, 2000. JPMIM's parent company is a significant
minority shareholder of ACIM's parent company. (See Note 2 in Notes to Financial
Statements.)

FUND BACKGROUND

     To better serve investors, RREEF and American Century merged an existing
fund managed by RREEF, RREEF Real Estate Securities Fund, into ACRE on June 13,
1997.

     The RREEF fund commenced operations on September 21, 1995, and had $25
million in assets at the time of the merger. ACRE was offered to the public by
American Century on June 16, 1997.

COMPARATIVE INDICES

     The following indices are used in the report as fund performance
comparisons. They are not investment products available for purchase.

     The S&P SMALL CAP 600 INDEX consists of 600 domestic stocks chosen for
market size, liquidity, and industry group representation.

     The S&P MIDCAP 400 INDEX is the medium capitalization sector of the U.S.
market. Created by Standard & Poor's, it is considered to represent the
performance of mid-cap stocks in general.

     The S&P 500 INDEX is a capitalization-weighted index of 500 widely traded
stocks. Created by Standard & Poor's, it is considered to represent the
performance of the stock market in general.

     The MORGAN STANLEY REIT INDEX is a market capitalization-weighted
total-return index of real estate investment trusts (REITs) that meet certain
liquidity requirements. The index was designed to track the total-return
performance of a broad group of REIT stocks, assuming dividend reinvestment in
the index on the ex-dividend date.

     The WILSHIRE REIT INDEX (full name: Wilshire Real Estate Securities Index -
REIT component) is a market capitalization-weighted index composed of 98 equity
REITs. It does not include special purpose or healthcare REITs.

Glossary
--------------------------------------------------------------------------------

RETURNS

*   TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

*   AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 16-18.

INVESTMENT TERMS

*   FUNDS FROM OPERATIONS (FFO)-- FFO is the most commonly used measure of a
REIT's earnings performance. It is similar to the net income of non-real estate
companies. FFO is the company's net income with real estate depreciation and
amortization (excluding deferred financing costs) added back in. The FFO ratio
is the price of the stock divided by the company's FFO. It is comparable to a
P/E ratio. The median FFO is in the middle of the REIT's portfolio. Half the
companies in the portfolio have FFOs greater than the median, and half have FFOs
that are less. If the portfolio contains an even number of companies, then the
median is the average of the two company FFOs in the middle.

*   MEDIAN MARKET CAPITALIZATION-- market capitalization (market cap) is the
total value of a company's stock and is calculated by multiplying the number of
outstanding common shares by the current share price. The company whose market
cap is in the middle of the portfolio is the median market cap. Half the
companies in the portfolio have values greater than the median, and half have
values that are less. If there is an even number of companies, then the median
is the average of the two companies in the middle.

*   WEIGHTED AVERAGE MARKET CAPITALIZATION-- average market capitalization
represents the average value of the companies held in a portfolio. When that
figure is weighted, the impact of each company's capitalization on the overall
average is proportional to the total market value of its shares.

*   NUMBER OF COMPANIES-- the number of different companies held by a fund on a
given date.

*   PORTFOLIO TURNOVER-- the percentage of a fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

*   PRICE/BOOK RATIO-- a stock value measurement calculated by dividing a
company's stock price by its book value per share, with the result expressed as
a multiple instead of as a percentage. (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)

*   PRICE/EARNINGS (P/E) RATIO-- a stock value measurement calculated by
dividing a company's stock price by its earnings per share, with the result
expressed as a multiple instead of as a percentage. (Earnings per share is
calculated by dividing the after-tax earnings of a corporation by its
outstanding shares.) When this figure is weighted, the impact of each company's
P/E ratio is in proportion to the percentage of the fund that the company
represents.

TYPES OF STOCKS

*   BLUE CHIP STOCKS-- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

*   CYCLICAL STOCKS-- generally considered to be stocks whose price and earnings
fluctuations tend to follow the ups and downs of the business cycle. Examples
include the stocks of automobile manufacturers, steel producers and textile
operators.

*   GROWTH STOCKS-- stocks of companies that have experienced above-average
earnings growth and are expected to continue such growth. These stocks often
sell at high P/E ratios. Examples can include the stocks of high-tech,
healthcare and consumer staple companies.

*   LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
more than $9.9 billion. This is Lipper's market capitalization breakpoint as of
September 30, 2000, although it may be subject  to change based on market
fluctuations. The Dow Jones Industrial Average and the S&P 500 Index generally
consist of stocks in this range.

*   MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
between $2.3 billion and $9.9 billion. This is Lipper's market capitalization
breakpoint as of September 30, 2000, although it may be subject to change
based on market fluctuations. The S&P 400 Index and Russell 2500 Index
generally consist of stocks in this range.

*   SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
less than $2.3 billion. This is Lipper's market capitalization breakpoint as
of September 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 600 Index and the Russell 2000 Index generally consist
of stocks in this range.

*   VALUE STOCKS-- generally considered to be stocks that are purchased because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

FUND CLASSIFICATIONS

    Please be aware that the fund's category may change over time. Therefore, it
is important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies and risk potential are consistent
with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

*   CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

*   INCOME -- offers funds that can provide current income and competitive
yields, as well as a strong and stable foundation and generally lower volatility
levels than stock funds.

*   GROWTH & INCOME -- offers funds that emphasize both growth and income
provided by either dividend-paying equities or a combination of equity and
fixed-income securities.

*   GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with correspondingly high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

*   CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

*   MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

*   AGGRESSIVE -- these funds generally provide high return potential with
correspondingly high price-fluctuation risk.

  2000 will close on December 15, 2000. The fund closed to new investors on

James E. Stowers, Jr., standing, with James E. Stowers III

   U.S. stocks sputtered during the second and third quarters of 2000 as rising
oil prices and a plummeting euro--the European currency--created new concerns
for investors. The period was marked by heightened nervousness about corporate
earnings, especially for richly priced technology companies. Investors punished
growth stocks nearly across the board in September, when several bellwether tech
companies warned of lower-than-expected third quarter earnings. As a result,
Equity Index, which closely tracks the S&P 500 Index, finished the six months
with a modest decline.

   Turning to corporate matters, Chase Manhattan Corp. recently announced plans
to acquire J.P. Morgan & Co., a substantial minority shareholder in American
Century Companies, Inc. since 1998. If the transaction is completed as expected,
J.P. Morgan Chase, the new enterprise, will own the shares of American Century
currently held by Morgan. Corporate control of American Century is not affected
by this transaction. We will be exploring ways to partner with J.P. Morgan Chase
for the benefit of fund shareholders.

   In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to share chairman of the
board responsibilities, and also named American Century President William M.
Lyons chief executive officer, giving him ultimate management responsibility for
the entire company.

   These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue additional worthwhile endeavors. For example, Jim Stowers III will focus
more on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next generation of portfolio management
technologies). However, his first priority will be continuing involvement on the
investment teams responsible for the Ultra and Veedot funds.

   As always, we appreciate your continued confidence in American Century.

Sincerely,

/signature/James E.Stowers, Jr and James E. Stowers III

* U.S. stocks struggled during the second and third quarters of 2000 as rising
  oil prices, a slowing economy and a plummeting euro created new concerns for
  investors.

* The period was marked by heightened nervousness about corporate earnings,
  especially for technology companies. Investors generally punished growth
  stocks in September, when several bellwether tech companies warned of
  lower-than-expected third quarter earnings.

* In this environment, the Standard & Poor's 500 Index posted a modest loss of
  3.60%. As an indication of the change in investor sentiment toward
  technology-oriented companies, the Nasdaq Composite Index fell 19.68% during
  the same period.

EQUITY INDEX

* Equity Index declined 3.94% for the six months ended September 30, 2000. The
  fund's slight underperformance versus that of the S&P 500 Index, which it
  tracks, takes into account the fund's management fee.

* The fund was slowed by a sharp correction in technology and telecommunications
  stocks, which had been market leaders during the previous six months. With the
  economy appearing to slow after six interest rate hikes by the Federal Reserve
  since mid-1999, investors had little patience with richly priced technology
  companies whose earnings came in below the market's very high expectations.

* Weakness in the technology sector was fairly broad-based, with industries such
  as computer hardware, software, electrical equipment and semiconductors all
  posting losses for the six months.

* In this uncertain climate, investors sought companies that could provide more
  predictable earnings. That mission took them to utilities, the best performing
  sector in the S&P 500 for the period, and healthcare companies, particularly
  pharmaceutical firms, hospitals and HMOs.

* The financial sector, which had been slowed by rising interest rates,
  rebounded strongly toward the end of the period as investors became
  increasingly confident that the Federal Reserve would not be moving interest
  rates higher in the short term. Among the biggest beneficiaries of this
  sentiment were banks and property and casualty insurers.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------

Mark Mallon, chief investment officer, specialty, asset allocation, and growth
and income equities

The six months ended September 30, 2000, proved to be difficult for stock market
investors. The Standard & Poor's 500 Index posted a negative return of 3.60% for
the period, as the previously high-flying technology and telecommunications
sectors suffered significant losses. At the same time, sectors that had been
out-of-favor, such as financials and utilities, witnessed a rebound.

    Investors who had been willing to pay exorbitant prices for some stocks that
offered only the promise of future earnings became spooked by a slew of earnings
warnings from some prominent tech and telecom companies. Much of the downdraft
occurred in September, after the technology-laden Nasdaq Composite Index had
reached lofty heights in August.

REBIRTH FOR OLD ECONOMY STOCKS

    The market witnessed a sea change during the period, as investors focused
much more on what they were paying for a company's earnings. For that reason,
many Old Economy stocks witnessed a rebound, while many New Economy firms were
brought back down to earth. Investors also felt more comfortable widening their
scope; the economy showed enough signs of a slowdown that the Federal Reserve
Board felt it could forego further increases in interest rates. With more
Interest rate stability, financial stocks posted noteworthy gains. Another
sector of the Old Economy that attracted interest was energy, where skyrocketing
oil and natural gas prices helped lift the share prices of most companies.

INVESTORS LOOK FOR SAFETY, AND SHIFT TO VALUE AND MID-CAP STOCKS

    Within a fairly volatile stock market environment, sectors that offered some
modicum of protection led the way. The utilities sector offered the best
absolute returns within the S&P 500. There, investors found stable earnings and
the promise offered by industry deregulation. These stocks also tend to be
interest rate sensitive, so the Fed's lack of action also helped lift their
shares. Other sectors offering steady, regular earnings -- such as food,
beverage, and healthcare stocks -- became market leaders.

    Overall, the market turned away from the high-growth, large-capitalization
tendencies it had exhibited over the past several years. Once investors started
looking elsewhere, they found particular value in many pockets of the market,
including mid-cap stocks. As a result, mid-capitalization companies posted the
most significant gains during the period; the S&P MidCap 400 returned a very
healthy 8.45%.

A FOCUS ON EARNINGS AND PRICE

    The U.S. economy appears to have lost some of its momentum, reflecting that
corporate earnings growth appears to have slowed. Market volatility could remain
part of the picture, as investors look for companies whose earnings meet or beat
expectations and shun those that do not. With interest rates stable, a company's
earnings growth and stock valuation should become more significant factors in
determining whether or not it performs well.

Equity Index--Q&A
--------------------------------------------------------------------------------

     An interview with Barclays Global Investors, the subadvisor on the Equity
Index Fund.

HOW DID EQUITY INDEX PERFORM DURING THE SIX MONTHS ENDED SEPTEMBER 30, 2000?

     Equity Index declined 3.94%* during the period compared to a 3.60% decline
for the Standard & Poor's 500 Index.

WHY DID THE MARKET POST NEGATIVE RETURNS FOR THE SIX-MONTH PERIOD?

     Several key sectors witnessed sharp declines during this time. Most notable
was technology -- the largest sector within the S&P 500 at around 32% -- which
had been riding high in late 1999 and early 2000. With some large technology
companies struggling to meet their earnings targets, investors became less
inclined to maintain investments in companies whose stock prices reflected, in
some cases, unreasonably promising earnings trends. In addition, the
telecommunications sector stumbled, knocked off-balance by a number of issues,
including the collapse of the WorldCom/ Sprint merger. Finally, certain cyclical
sectors -- those whose prospects move in synch with the economy -- were caught
in a downdraft, some due to concerns that the economy would cool off
significantly because of Federal Reserve Board interest rate hikes, others
because of poor commodity pricing.

NEVERTHELESS, THERE MUST HAVE BEEN POCKETS OF OPPORTUNITY...

     Absolutely. With many technology stocks on the decline, investors turned
their attention to the Old Economy stocks that were neglected during the
record-shattering days of the fourth quarter of 1999 and the first quarter of
2000.

     The best-performing sector was utilities. These stocks were considered safe
havens amid the stock market volatility of the past six months. In addition,
utilities investments were helped by the growing perception that the Fed might
be nearing or reaching the end of its most recent rate hike cycle. Stocks of
utilities are very sensitive to changes in interest rates because they generally
generate healthy dividend income. Finally, deregulation in the industry put some
wind in these companies' sails. Among the stocks in the sector that performed
best were AES Corp., Entergy, Reliant Energy, and PPL Corp.

     Health care also proved to be fertile ground, with pharmaceutical
companies, hospitals and HMOs among its leaders. These companies attracted
investors because they tend to offer steady earnings -- a positive
characteristic in an uncertain environment -- and were selling at more
reasonable share prices than were the technology and telecommunications sectors.
The same attributes drew investors to consumer non-cyclical stocks, such as food
and beverage and supermarket companies. Among the health care and consumer
non-cyclical stocks that posted significant share-price gains were Cardinal
Health, Allergan, Alza Corp., Unitedhealth Group, Bestfoods, and Nabisco.

WHAT ABOUT FINANCIAL STOCKS, WHICH MAKE UP THE SECOND-LARGEST SECTOR OF THE S&P
500?

     This sector rebounded smartly. Share prices in the financial sector had
been beaten down steadily over the past 12 to 18 months because of the negative
influence of Federal Reserve rate hikes. As the second and third quarters of

Equity Index--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

2000 progressed, emerging data pointed to a slowing economy, and the Fed stopped
raising rates. In response, investors became more willing to look at the
long-term prospects of financial companies and sentiment toward them improved.
Banks such as Mellon Financial performed particularly well. Other strong
performers in the sector included property and casualty insurers, such as
Allstate, which benefited from an improved pricing environment.

HAVE HIGHER ENERGY PRICES BOOSTED ENERGY COMPANY SHARES?

     Yes. Remember, it wasn't that long ago that oil prices were extremely low
and energy companies lagged well behind New Economy firms. As the Organization
of Petroleum Exporting Countries (OPEC) tightened production quotas, oil prices
marched steadily upward to 30-year highs. This, despite political pressure that
encouraged OPEC to increase production modestly, and President Clinton's
decision to tap into the national strategic petroleum reserve in an attempt to
keep prices down. We witnessed rekindled activity for companies whose earnings
are highly sensitive to the price of oil, namely energy services providers and
exploration and production firms. The performance of many of these companies was
further buoyed by increases in the price of natural gas. As with oil, demand for
natural gas continued to grow while supply grew even tighter.

WHICH SECTORS PROVED TO BE THE MOST DISAPPOINTING DURING THE PERIOD?

     As we said, technology really dragged the S&P 500 down during the six
months in question. Weakness in the sector was fairly broad-based, with
industries such as computer hardware, software, electrical equipment, and
semiconductors posting losses. On the computer side, Apple and Dell suffered
from earnings shortfalls, while software provider Computer Associates was
dragged down by a lag in the production of a new mainframe by its number one
client, IBM. Within the sector, however, there were some pockets of solid
performance. Corning's leadership position as a fiberoptic network equipment
provider helped insulate it from many of the problems encountered within the
electrical equipment industry. And, defense and aerospace offered healthy
returns, paced by the strong performance of Northrop Grumman, Lockheed Martin,
and Boeing. Last year, investors appeared worried that Boeing's airplane orders
would decline. However, with the global economy on the rebound, Boeing's
production outlook for the next few years has improved. In addition, the company
became more efficient, significantly improving profits per plane.

     Telecommunications were another problem spot. The failed merger between
WorldCom and Sprint put a damper on the excitement inspired by potential
consolidation activity, which had been encouraged by the telecommunications
deregulation legislation of 1996. In addition, other companies, such as AT&T,
suffered from a weak long-distance pricing climate.

WHAT IS THE OUTLOOK?

     While it's impossible to predict the direction of the stock market, we can
review the factors that might color the market backdrop. First, the
interest rate environment appears to be more favorable than in the past year or
so. There

have been signs that the economy is slowing and that inflation appears under
control. These factors, coupled with the upcoming presidential election, will
probably keep the Fed on the sidelines for the foreseeable future. That should
be a positive for the stock market. What's more uncertain is the effect of
rising energy prices. Will they effectively dampen growth by limiting economic
activity, or will they spark more broad-based inflation? Other issues that could
be influential are the results of the election itself, as well as  turmoil in
the Middle East and the continuing struggles of the euro.

  In the short term, with interest rates firm and inflation still benign, the
main driver of the market is likely to be corporate earnings. That said, we will
have to wait and see if investors continue to evaluate more closely what they
are paying for a company's earnings. Or, like last year, will they pay any price
for the market's best earnings growth? What kinds of stocks will lead the market
averages? Old Economy? New Economy? Only time will provide the answers.

*Futures contracts typically are based on a stock index, such as the S&P 500,
and tend to track the performance of the index while remaining very liquid (easy
to buy and sell).  By investing its cash assets in index futures, the fund can
have full exposure to stocks and have easy access to the money. Temporary cash
investments, less the required reserves for futures contracts, are 0.1% of total
investments.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other payables) as of the last day of the reporting period.
Subtracting the liabilities from the assets results in the fund's NET ASSETS.
The net assets divided by shares outstanding is the share price, or NET ASSET
VALUE PER SHARE. This statement also breaks down the fund's net assets into
capital (shareholder investments) and performance (investment income and
gains/losses).

Notes to Financial Statements
--------------------------------------------------------------------------------

SEPTEMBER 30, 2000 (UNAUDITED)
--------------------------------------------------------------------------------
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Capital Portfolios, Inc. (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. American Century Equity Index Fund (the
fund) is one of the six funds issued by the corporation. The fund is
non-diversified under the 1940 Act. The investment objective of the fund is
long-term capital growth. The fund seeks to achieve this objective by matching,
as closely as possible, the investment results of the Standard & Poor's 500
Composite Stock Price Index. The following significant accounting policies are
in accordance with generally accepted accounting principles; these policies may
require the use of estimates by fund management.

    MULTIPLE CLASS -- The fund is authorized to issue two classes of shares: the
Investor Class and the Institutional Class. The two classes of shares differ
principally in their respective shareholder servicing and distribution expenses
and arrangements. All shares of the fund represent an equal pro rata interest in
the assets of the class to which such shares belong, and have identical voting,
dividend, liquidation and other rights and the same terms and conditions, except
for class specific expenses and exclusive rights to vote on matters affecting
only individual classes.

    SECURITY VALUATIONS --  Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no last sales price is available. When
valuations are not readily available, securities are valued at fair value as
determined in accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS --  Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME --  Dividend income less foreign taxes withheld (if any)
is recorded as of the ex-dividend date. Interest income is recorded on the
accrual basis and includes accretion of discounts and amortization of premiums.

    FUTURES CONTRACTS --  The fund may enter into stock index futures contracts
in order to manage the fund's exposure to changes in market conditions. One of
the risks of entering into futures contracts is the possibility that the change
in value of the contract may not correlate with the changes in value of the
underlying securities. Upon entering into a futures contract, the fund is
required to deposit either cash or securities in an amount equal to a certain
percentage of the contract value (initial margin). Subsequent payments
(variation margin) are made or received daily, in cash, by the fund. The
variation margin is equal to the daily change in the contract value and is
recorded as unrealized gains and losses. The fund recognizes a realized gain or
loss when the contract is closed or expires. Net realized and unrealized gains
or losses occurring during the holding period of futures contracts are a
component of realized gain (loss) on investments and unrealized appreciation
(depreciation) on investments, respectively.

    REPURCHASE AGREEMENTS --  The fund may enter into repurchase agreements with
institutions that the fund's investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. The fund requires that the collateral, represented by securities, received
in a repurchase transaction be transferred to the custodian in a manner
sufficient to enable the fund to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure the value, including accrued interest, of the
securities under each repurchase agreement is equal to or greater than amounts
owed to the fund under each repurchase agreement.

    JOINT TRADING ACCOUNT --  Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME TAX STATUS --  It is the fund's policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS --  Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid quarterly. Distributions from net realized gains are declared and paid
annually.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    For the five month period ended March 31, 2000, Equity Index incurred net
capital losses of $856,910. The fund has elected to treat such losses as having
been incurred in the following fiscal year.

2. TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the fund with investment advisory and management services in
exchange for a single, unified management fee per class. The Agreement provides
that all expenses of the fund, except brokerage commissions, taxes, interest,
expenses of those directors who are not considered "interested persons" as
defined in the 1940 Act (including counsel fees) and extraordinary expenses,
will be paid by ACIM. The fee is computed daily and paid monthly based on the
fund's class average daily closing net assets during the previous month. The
annual management fee is 0.49% and 0.29% for the Investor and Institutional
Class, respectively.

    ACIM has entered into a Subadvisory Agreement with Barclays Global Fund
Advisors (BGFA) on behalf of the fund. The subadvisor makes investment decisions
for the fund in accordance with the fund's investment objectives, policies and
restrictions under the supervision of ACIM and the Board of Directors. ACIM pays
all costs associated with retaining BGFA as the subadvisor of the fund.

    Certain officers and directors of the corporation are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, the
distributor of the corporation, American Century Services, Inc., and the
corporation's transfer agent, American Century Services Corporation.

--------------------------------------------------------------------------------
3. INVESTMENT TRANSACTIONS

    Purchases and sales of investment securities, excluding short-term
investments, for the six months ended September 30, 2000, were $56,956,968 and
$14,330,366, respectively.

    On September 30, 2000, accumulated net unrealized appreciation on
investments was $50,452,771, based on the aggregate cost of investments for
federal income tax purposes of $441,999,296, which consisted of unrealized
appreciation of $101,457,094 and unrealized depreciation of $51,004,323.

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Two classes of shares are authorized for sale by the fund: Investor Class
and Institutional Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    INSTITUTIONAL CLASS shares are available to endowments, foundations, defined
benefit pension plans or financial intermediaries serving these investors. This
class recognizes the relatively lower cost of serving institutional customers
and others who invest at least $5 million in an American Century fund or at
least $10 million in multiple funds. In recognition of the larger investments
and account balances and comparatively lower transaction costs, the total
expense ratio of the Institutional Class shares is 0.20% less than the total
expense ratio of the Investor Class shares.

    All classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.


RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

    American Century offers 15 growth and income funds including domestic
equity, balanced, asset allocation, and specialty.

    The Equity Index Fund seeks to match, as closely as possible, the investment
characteristics and results of the S&P 500 Index. The S&P 500 Index comprises
500 selected common stocks, most of which are listed on the New York Stock
Exchange. The fund is managed by buying and selling stocks and other securities
in order to build an investment portfolio that will match, as closely as
possible, the investment characteristics of the S&P 500 Index.

    Standard & Poor's, a division of The McGraw-Hill Companies, Inc., chooses
the stocks included in the S&P 500 Index on a market capitalization-weighted
basis. The weightings of stocks in the S&P 500 Index are further based on each
stock's total market capitalization relative to the other stocks contained in
the index. Because of this weighting, the fund expects that the 50 largest
companies will make up a large proportion of the S&P 500 Index.

    The advisor generally will select stocks for the fund's portfolio in order
of their weightings in the S&P 500 Index, beginning with the heaviest-weighted
stocks. The fund attempts to be fully invested at all times in the stocks that
make up the S&P 500 Index, and, in any event, at least 80% of the fund's total
assets will be so invested.


FUND MANAGEMENT

    Barclays Global Fund Advisors (BGFA), a subsidiary of Barclays Global
Investors (BGI), serves as subadvisor of the American Century Equity Index Fund,
with oversight by American Century's quantitative equity group.

    In 1971, BGI introduced the concept of indexing. With assets under
management of more than $600 billion, BGI is the world's largest institutional
investment firm. BGI's clients include corporate and government retirement
plans, universities, foundations, financial planning advisors, mutual fund
distributors and central banks. A subsidiary of London, UK-based Barclays PLC,
BGI is headquartered in San Francisco, CA, and has offices worldwide.

COMPARATIVE INDICES

    The following indices are used in the report for fund performance
comparisons. They are not investment products available for purchase.

    The S&P 500 is a capitalization-weighted index of the stocks of 500 publicly
traded U.S. companies that are considered to be leading firms in dominant
industries. Created by Standard & Poor's, it is considered to be a broad measure
of U.S. stock market performance.

    The S&P MIDCAP 400 is the medium capitalization sector of the U.S. market.
Created by Standard & Poor's, it is considered to represent the performance of
mid-cap stocks generally.

    The RUSSELL 2000 INDEX was created by the Frank Russell Company. It measures
the performance of the 2,000 smallest of the 3,000 largest publicly traded U.S.
companies based on total market capitalization. The Russell 2000 represents
approximately 10% of the total market capitalization of the top 3,000 companies.
The average market capitalization of the index is approximately $420 million.

Glossary
--------------------------------------------------------------------------------

RETURNS

*   TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

*   AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 21-22.

INVESTMENT TERMS

*   MEDIAN MARKET CAPITALIZATION-- market capitalization (market cap) is the
total value of a company's stock and is calculated by multiplying the number of
outstanding common shares by the current share price. The company whose market
cap is in the middle of the portfolio is the median market cap. Half the
companies in the portfolio have values greater than the median, and half have
values that are less. If there is an even number of companies, then the median
is the average of the two companies in the middle.

*   WEIGHTED AVERAGE MARKET CAPITALIZATION-- average market capitalization
represents the average value of the companies held in a portfolio. When that
figure is weighted, the impact of each company's capitalization on the overall
average is proportional to the total market value of its shares.

*   NUMBER OF COMPANIES-- the number of different companies held by a fund on a
given date.

*   PORTFOLIO TURNOVER-- the percentage of a fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

*   PRICE/BOOK RATIO-- a stock value measurement calculated by dividing a
company's stock price by its book value per share, with the result expressed as
a multiple instead of as a percentage. (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)


*   PRICE/EARNINGS (P/E) RATIO-- a stock value measurement calculated by
dividing a company's stock price by its earnings per share, with the result
expressed as a multiple instead of as a percentage. (Earnings per share is
calculated by dividing the after-tax earnings of a corporation by its
outstanding shares.) When this figure is weighted, the impact of each company's
P/E ratio is in proportion to the percentage of the fund that the company
represents.

TYPES OF STOCKS

*   BLUE CHIP STOCKS-- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

*   CYCLICAL STOCKS-- generally considered to be stocks whose price and earnings
fluctuations tend to follow the ups and downs of the business cycle. Examples
include the stocks of automobile manufacturers, steel producers and textile
operators.

*   GROWTH STOCKS-- stocks of companies that have experienced above-average
earnings growth and are expected to continue such growth. These stocks often
sell at high P/E ratios. Examples can include the stocks of high-tech,
healthcare and consumer staple companies.

*   LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $9.9 billion. This is Lipper's market capitalization breakpoint as of
September 30, 2000, although it may be subject to change based on market
fluctuations. The Dow Jones Industrial Average and the S&P 500 Index generally
consist of stocks in this range.

*   MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
between $2.3 billion and $9.9 billion. This is Lipper's market capitalization
breakpoint as of September 30, 2000, although it may be subject to change based
on market fluctuations. The S&P 400 Index and Russell 2500 Index generally
consist of stocks in this range.

*   SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
less than $2.3 billion. This is Lipper's market capitalization breakpoint as of
September 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 600 Index and the Russell 2000 Index generally consist of
stocks in this range.

*   VALUE STOCKS-- generally considered to be stocks that are purchased because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

FUND CLASSIFICATIONS

    Please be aware that a fund's category may change over time. Therefore, it
is important that you read the fund's prospectus or fund profile carefully
before investing to ensure its objectives, policies and risk potential are
consistent with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

*   CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

*   INCOME -- offers funds that can provide current income and competitive
yields, as well as a strong and stable foundation and generally lower volatility
levels than stock funds.

*   GROWTH & INCOME -- offers funds that emphasize both growth and income
provided by either dividend-paying equities or a combination of equity and
fixed-income securities.

*   GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with correspondingly high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

*   CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

*   MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

*   AGGRESSIVE -- these funds generally provide high return potential with
correspondingly high price-fluctuation risk.

The investment objective may be based on the fund's objective as stated in its
prospectus or fund profile, or the fund's categorization by independent rating
organizations based on its management style.

The classification of funds by risk category is based on quantitative historical
measures as well as qualitative prospective measures. It is not intended to be a
precise indicator of future risk or return levels. The degree of risk within
each category can vary significantly, and some fund returns have historically
been higher than more aggressive funds or lower than more conservative funds.
Please be aware that a fund's category may change over time. Therefore, it is
important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies and risk potential are consistent
with your needs. For a definition of fund categories, see the Glossary.

* While listed within the Income investment objective, the Target funds do not
  pay current dividend income. Income  dividends are distributed once a year in
  December. The Target funds are listed in all three risk categories due to the
  dramatic price volatility investors may experience during certain market
  conditions. If held to their target dates,  however, they can offer a
  conservative, dependable way to invest for a specific time horizon. Target
  2000 will close on December 15, 2000. The fund closed to new investors on
  10/1/2000, and will no longer accept investments from current shareholders
  beginning 11/01/2000.

Please call 1-800-345-2021 for a prospectus or profile on any American Century
fund. These documents contain important information including charges and
expenses, and you should read them carefully before you invest or send money.
