Item 1. Report to Shareholders.

The Fund’s semi-annual report transmitted to shareholders pursuant to Rule 30e-1
under the Investment Company Act of 1940 is as follows:

Welcome, Shareholder

In this report, you’ll learn about how your investment in Van Kampen Money Market Fund, formerly Reserve Fund, performed during the semiannual period. The portfolio management team will provide an overview of the market conditions and discuss some of the factors that affected investment performance during the reporting period. In addition, this report includes the fund’s financial statements and a list of fund investments as of November 30, 2008.

This material must be preceded or accompanied by a prospectus for the fund being offered. The prospectus contains information about the fund, including the investment objectives, risks, charges and expenses. Please read the prospectus carefully before investing.

Market forecasts provided in this report may not necessarily come to pass. There is no assurance that a mutual fund will achieve its investment objective. Funds are subject to market risk, which is the possibility that the market values of securities owned by the fund will decline and that the value of the fund shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in this fund.

An investment in a money market fund is neither insured nor guaranteed by the Federal Deposit Insurance Corporation nor any other government agency. Although money market funds seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit vankampen.com or speak with your financial advisor. Investment returns and principal value will fluctuate and fund shares, when redeemed, may be worth more or less than their original cost.

Average annual total return includes a contingent deferred sales charge of 4.00 percent for Class B shares (in the first and second year and declining to zero after year five), a contingent deferred sales charge of 1.00 percent for Class C shares in year one and combined Rule 12b-1 fees and service fees of up to 0.15 percent for Class A shares and up to 0.90 percent for Class B and C shares. The Since Inception and 10-year returns for Class B shares reflect the conversion of Class B shares into Class A shares eight years after purchase. The fund’s adviser has waived or reimbursed fees and expenses from time to time; absent such waivers/reimbursements, the fund’s returns would have been lower. Periods of less than one year are not annualized.

Figures shown above assume reinvestment of all dividends and capital gains. The returns shown in this report do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance of share classes will vary due to differences in sales charges and expenses.

Fund Report

For the six-month period ended November 30, 2008

Market Conditions

The U.S. economy weakened considerably during the six-month review period. After rising in the first two quarters of 2008, gross domestic product (GDP) growth fell to –0.5 percent in the third quarter in a decline which is widely expected to have accelerated into the fourth quarter. Other economic data reflected the weakness, with employment figures negative for every month of 2008 to date and the Institute for Supply Management (ISM) Index, a measure of manufacturing activity, falling to its lowest level in more than 25 years. The residential housing market remained depressed, as home sales and prices continued to decline. Although commodity and fuel prices declined sharply during the period, consumer confidence continued to wane as fears of recession grew. These fears were realized in November when it was declared that the U.S. economy had, in fact, slid into recession.

The weakening economic outlook, coupled with credit and liquidity constraints and mortgage defaults, made for an extremely volatile market throughout the period under review. The Federal Reserve (the “Fed”) and the Treasury made considerable efforts to support both the market and the economy, including a range of innovative programs as well as aggressive reductions in the federal funds target rate and discount rate. These actions were often taken in coordination with central banks across the developed world. At the end of the period, these measures had in part helped to reduce the credit bellwether London Interbank Offered Rate (LIBOR) from its prior record levels, though LIBOR remained well above the Fed’s policy target for federal funds of 1 percent.

Performance Analysis

For the six-month period ended November 30, 2008, the Fund provided a total return of 0.67 percent (Class A shares). For the seven-day period ended November 30, 2008, the Fund provided an annualized yield of 0.05 percent, while its 30-day average annualized yield was 0.10 percent for the Class A shares. Yield quotations more closely reflect the current earnings of the portfolio.

Total returns for the six-month period ended November 30, 2008


Class A			Class B			Class C

	0.67	%		0.42	%		0.42	%

The performance for the three share classes varies because each has different expenses. The Fund’s total return figures assume the reinvestment of all distributions, but do not reflect the deduction of any applicable sales charges. Such costs would lower performance. Past performance is no guarantee of future results. See Performance Summary for standardized performance information.

As of the end of the period, the Fund had net assets of approximately $906 million. The average maturity of the portfolio was 12 days.

Throughout the reporting period, the Fund continued to seek high liquidity and preservation of capital while generating a yield reflecting prevailing money market conditions. To do this, the management team continued its long standing policy of purchasing only high quality, very liquid, money market securities. The Fund’s portfolio did not contain any derivative securities as of the end of the reporting period.

There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Fund in the future.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including contingent deferred sales charges on redemptions of Class B and Class C Shares; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 6/1/08 - 11/30/08.

Actual Expense

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or contingent deferred sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your cost would have been higher.

	Account Value		Account Value		During Period*

	6/1/08		11/30/08		6/1/08-11/30/08

*		Expenses are equal to the Fund’s annualized expense ratio of 0.83%, 1.31% and 1.31% for Class A, B and C Shares, respectively, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). These expense ratios reflect an expense waiver.

Assumes all dividends and distributions were reinvested.

Van Kampen Money Market Fund

Notes to Financial Statements n November 30, 2008 (Unaudited)

1. Significant Accounting Policies

Van Kampen Money Market Fund (formerly Reserve Fund) (the “Fund”) is organized as a Delaware statutory trust. The Fund is an open-end diversified management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s investment objective is to seek protection of capital and high current income. The Fund’s investment adviser seeks to achieve this objective through investments in U.S. dollar denominated money market securities. The Fund commenced investment operations on July 12, 1974. The Fund offers Class A Shares, Class B Shares and Class C Shares. Each class of shares differs by its initial sales load, contingent deferred sales charges, the allocation of class-specific expenses and voting rights on matters affecting a single class.

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

A. Security Valuation Investments are valued at amortized cost, which approximates market value. Under this valuation method, a portfolio instrument is initially recorded at cost, any discount is accreted and any premium is amortized on a straight-line basis to the maturity of the instrument.

The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”), effective June 1, 2008. In accordance with FAS 157, fair value is defined as the price that the Fund would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. FAS 157 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund’s investments. The inputs are summarized in the three broad levels listed below.


Level 1—	quoted prices in active markets for identical investments
Level 2—	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)
Level 3—	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Van Kampen Money Market Fund
Notes to Financial Statements n November 30, 2008 (Unaudited) continued

The following is a summary of the inputs used as of November 30, 2008 in valuing the Fund’s investments carried at value:


	Investments in
Valuation Inputs	Securities

Level 1—Quoted Prices	$	-0-
Level 2—Other Significant Observable Inputs		907,198,253
Level 3—Significant Unobservable Inputs		-0-

Total	$	907,198,253

B. Security Transactions Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis.

The Fund may invest in repurchase agreements, which are short-term investments in which the Fund acquires ownership of a debt security and the seller agrees to repurchase the security at a future time and specified price. The Fund may invest independently in repurchase agreements, or transfer uninvested cash balances into a pooled cash account along with other investment companies advised by Van Kampen Asset Management (the “Adviser”) or its affiliates, the daily aggregate of which is invested in repurchase agreements. Repurchase agreements are fully collateralized by the underlying debt security. The Fund will make payment for such securities only upon physical delivery or evidence of book entry transfer to the account of the custodian bank. The seller is required to maintain the value of the underlying security at not less than the repurchase proceeds due the Fund.

C. Income and Expenses Interest income is recorded on an accrual basis. Income and expenses of the Fund are allocated on a pro-rata basis to each class of shares, except for distribution and service fees and incremental transfer agency costs which are unique to each class of shares.

D. Federal Income Taxes It is the Fund’s policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income, if any, to its shareholders. Therefore, no provision for federal income taxes is required. The Fund adopted the provisions of the Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”) Accounting for Uncertainty in Income Taxes on November 30, 2007. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in “Interest Expense” and penalties in “Other” expenses on the Statement of Operations. The Fund files tax returns with the U.S. Internal Revenue Service and various states. Generally, each of the tax years in the four year period ended May 31, 2008, remains subject to examination by taxing authorities.

The Fund intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset such losses against any future realized capital gains. During the prior fiscal year, the Fund utilized capital losses carried forward of $8,792. At May 31, 2008, the Fund had an

Van Kampen Money Market Fund
Notes to Financial Statements n November 30, 2008 (Unaudited) continued

accumulated capital loss carryforward for tax purposes of $7,248, which will expire according to the following schedule.


Amount		Expiration

$	6,842		May 31, 2012
	406		May 31, 2013

E. Distribution of Income and Gains The Fund declares dividends daily from net investment income and automatically reinvests such dividends daily. Shareholders can elect to receive the cash equivalent of their daily dividends at each month end. The Fund distributes capital gains, if any, to shareholders at least annually.

The tax character of distributions paid during the year ended May 31, 2008 was as follows:


Distributions paid from:
Ordinary income	$	18,175,822

As of May 31, 2008, the component of distributable earnings on a tax basis was as follows:


Undistributed ordinary income		$	279,747

F. Credits Earned on Cash Balances During the six months ended November 30, 2008, the Fund’s custody was reduced by $17,355 as a result of credits earned on cash balances.

2. Investment Advisory Agreement and Other Transactions with Affiliates

Under the terms of the Fund’s Investment Advisory Agreement, the Adviser will provide investment advice and facilities to the Fund for an annual fee payable monthly as follows:


Average Daily Net Assets	% Per Annum

First $250 million		.450	%
Next $500 million		.375
Next $500 million		.325
Next $250 million		.300
Next $250 million		.275

Next $2.50 billion		.199
Next $7.50 billion		.198
Next $5.00 billion		.197
Over $30.00 billion		.196

For the six months ended November 30, 2008, the Fund recognized expenses of approximately $5,200 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such firm and he and his law firm provide legal services as legal counsel to the Fund.

Van Kampen Money Market Fund
Notes to Financial Statements n November 30, 2008 (Unaudited) continued

Under separate Accounting Services and Chief Compliance Officer (CCO) Employment agreements, the Adviser provides accounting services and the CCO provides compliance services to the Fund. The costs of these services are allocated to each fund. For the six months ended November 30, 2008, the Fund recognized expenses of approximately $24,400 representing Van Kampen Investments Inc.’s or its affiliates’ (collectively “Van Kampen”) cost of providing accounting services to the Fund, as well as the salary, benefits and related costs of the CCO and related support staff paid by Van Kampen. Services provided pursuant to the Accounting Services and CCO Employment agreement are reported as part of “Accounting and Administrative Expenses” on the Statement of Operations.

Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser, serves as the shareholder servicing agent for the Fund. For the six months ended November 30, 2008, the Fund recognized expenses of approximately $332,100 representing transfer agency fees paid to VKIS and its affiliates. Transfer agency fees are determined through negotiations with the Fund’s Board of Trustees.

Certain officers and trustees of the Fund are also officers and directors of Van Kampen. The Fund does not compensate its officers or trustees who are also officers of Van Kampen.

The Fund provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation. Amounts deferred are retained by the Fund and, to the extent permitted by the 1940 Act, may be invested in the common shares of those funds selected by the trustees. Investments in such funds of approximately $116,100 are included in “Other” assets on the Statement of Assets and Liabilities at November 30, 2008. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee’s years of service to the Fund. The maximum annual benefit per trustee under the plan is $2,500.

For the six months ended November 30, 2008, Van Kampen, as Distributor for the Fund, received net commissions on redeemed shares which were subject to a contingent deferred sales charge (CDSC) of approximately $311,600. Sales charges do not represent expenses to the Fund.

4. Distribution and Service Plans

Shares of the Fund are distributed by Van Kampen Funds Inc. (the “Distributor”), an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act, and a service plan (collectively, the “Plans”) for Class A Shares, Class B Shares and Class C Shares to compensate the Distributor for the sale, distribution, shareholder servicing and maintenance of shareholder accounts for these shares. Under the Plans, the Fund will incur annual fees of up to .15% of Class A average daily net assets and up to .90% each of Class B and Class C average daily net assets. These fees are accrued daily and paid to the Distributor monthly. The Distributor is currently waiving a portion of the distribution and service fees for Class B Shares and Class C Shares. For the six months ended November 30, 2008, the Distributor waived $260,984 of distribution and service fees. Due to the voluntary waiver, the aggregate distribution and service fees are currently .14%, .61% and .62% for Class A Shares, Class B Shares and Class C Shares, respectively. This waiver is voluntary in nature and can be discontinued at any time.

The amount of distribution expenses incurred by the Distributor and not yet reimbursed (“unreimbursed receivable”) was approximately $4,320,000 and $18,600 for Class B and Class C Shares, respectively. These amounts may be recovered from future payments under the distribution plan or CDSC. To the extent the unreimbursed receivable has been fully recovered, the distribution fee is reduced.

Notes to Financial Statements n November 30, 2008 (Unaudited) continued

5. Indemnifications

The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

6. Accounting Pronouncement

On March 19, 2008, Financial Accounting Standards Board released Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (FAS 161). FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of FAS 161 is required for fiscal years and interim periods beginning after November 15, 2008. At this time, management is evaluating the implications of FAS 161 and its impact on the financial statements has not yet been determined.

7. Subsequent Event

Effective January 20, 2009, Van Kampen Reserve Fund has been renamed Van Kampen Money Market Fund.

8. U.S. Treasury Temporary Guaranty Program

The Board of Trustees approved the participation by the Fund in the U.S. Department of the Treasury’s Temporary Guaranty Program (“Program”) for money market funds. Although the Fund has continued to maintain a net asset value of $1.00 per share, the Fund believes that participation in the Program will provide an added level of assurance for its shareholders. The Program provides a guarantee to participating money market mutual fund shareholders based on the number of shares invested in the Fund at the close of business on September 19, 2008. Any increase in the number of shares an investor holds after the close of business on September 19, 2008, will not be guaranteed. If a customer closes his/her account with the Fund or broker-dealer, any future investment in the Fund will not be guaranteed. If the number of shares an investor holds fluctuates over the period, the investor will be covered for either the number of shares held as of the close of business on September 19, 2008, or the current amount, whichever is less. The Program had originally been set to expire on December 18, 2008, but was recently extended by the Treasury Department until April 30, 2009. The expense of the Program, amounting to $177,237, is born by the Fund and amortized on a straight line basis over the term of the Program’s coverage.
