A US special forces soldier, Gannon Ken Van Dyke, has pleaded not guilty to charges that he used classified information about the mission to capture former Venezuelan leader Nicolas Maduro to win more than $400,000 on the prediction market Polymarket.

The 38-year-old entered his plea in Manhattan federal court after being charged with unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud, and making an unlawful monetary transaction.

Van Dyke was released on a $250,000 bail and is restricted to traveling within specific areas of New York, North Carolina, California, and the segments necessary to travel between them.

The case against Van Dyke includes evidence obtained through grand jury subpoenas, cryptocurrency exchange records, search warrants, and social media accounts.

Defense attorney Zach Intrater expressed skepticism over potential disputes but acknowledged that motions could significantly impact the case's outcome.

A pretrial conference is scheduled for June 8.
