Item 9.  Regulation FD Disclosure.

On October 24, 2002, MicroStrategy Incorporated (the "Company") issued a press
release (the "Press Release") providing financial guidance for the fourth
quarter of 2002. Revenue was expected to be in the range of approximately $35 to
$39 million. Pro forma results of operations, excluding special items, were
expected to range from breakeven to a profit of $2 million. Pro forma earnings
per share, excluding special items and assuming a diluted weighted average share
count, was expected to range from approximately breakeven to $0.15 per share.
Average share count in the quarter using the diluted weighted average share
count method was expected to be 13 to 14 million. A copy of the Press Release
was filed with the Company's Current Report on Form 8-K, dated October 24, 2002,
as Exhibit 99.1.

On December 10, 2002, in response to an investor inquiry, the Company said that
it was comfortable with the fourth quarter financial guidance provided in the
Press Release.

This report contains statements that constitute "forward-looking statements,"

(collectively, the "Company") to differ materially from the forward-looking
statements. Factors that could contribute to such differences include: the
Company's ability to secure financing for its current operations and long-term
plans on acceptable terms; the ability of the Company to implement and achieve
widespread customer acceptance of its MicroStrategy 7i software on a timely
basis; the Company's ability to recognize deferred revenue through delivery of
products or satisfactory performance of services; the Company's ability to
effect the sale of non-core assets on reasonable terms; continued acceptance of
the Company's products in the marketplace; the timing of significant orders;
delays in the Company's ability to develop or ship new products; market
acceptance of new products; competitive factors; general economic conditions;
currency fluctuations; and other risks detailed in the Company's registration
statements and periodic reports filed with the Securities and Exchange
Commission. By making these forward-looking statements, the Company undertakes
no obligation to update these statements for revisions or changes after the date
of this release.
