U.S. District Judge Denise Cote refused to set aside the verdict and dismiss the indictment against Aleynikov, or alternatively to grant him a new trial, court records dated Wednesday show.
The decision clears the way for Aleynikov to be sentenced on March 18. Federal prosecutors have requested a 97- to 121-month prison sentence. Aleynikov is seeking probation.
Kevin Marino, a lawyer for Aleynikov, did not immediately return a call seeking comment.
Cote last month jailed Aleynikov pending his sentencing, after prosecutors contended he could be a flight risk.
Aleynikov holds dual citizenship in the United States and Russia, and the court had heard that his wife was seeking a divorce and that he had become estranged from his in-laws.
A Manhattan federal jury last December 10 convicted Aleynikov on charges he copied and removed high-frequency trading code from Goldman in 2009, prior to taking a new job at a Chicago start-up firm.
The case is U.S. v. Aleynikov, U.S. District Court, Southern District of New York, No. 10-00096.
