On November 4, 2004, eSpeed, Inc. (the "Registrant") issued a press release announcing its preliminary operating statistics for the quarter ended September 30, 2004. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in this Current Report on Form 8-K and the Exhibit attached to this Current Report on Form 8-K are being furnished under Item 2.02 of Form 8-K. The information shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934 (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such filing.

In the press release, the Registrant uses non-GAAP financial measures of revenues, income before income tax provision, net income and earnings per share to supplement its consolidated financial statements presented in accordance with generally accepted accounting principles, or GAAP, and to better reflect its quarter-over-quarter and comparative quarterly operating performance. The Registrant also provides a computation of free cash flows. These non-GAAP financial measures do not replace the presentation of GAAP financial results but are provided to enhance overall understanding of the Registrant's current financial performance and prospects for the future. Specifically, the Registrant's management believes that the non-GAAP financial results provide useful information to both management and investors regarding certain additional financial and business trends relating to its financial condition and results from operations. In addition, management uses these measures for reviewing the Registrant's financial results and evaluating its financial performance.
