Army Sergeant Charged in Polymarket Insider Trading Case
US Army Special Operations sergeant Gannon Van Dyke pleaded not guilty in a Manhattan federal court to felony charges alleging he used confidential military information to win about $409,000 on the Polymarket prediction market related to the Maduro operation. A judge set bail at $250,000 with firearm surrender and travel restrictions to California, New York, and North Carolina. Prosecutors say he placed 13 bets totaling $33,000 between Dec 27, 2025 and Jan 2, 2026, with Polymarket flagging his winnings. He faces counts including unlawful use of confidential government information for personal gain, theft of non-public information, commodities fraud, wire fraud, and money laundering; he remains on leave from the Army and is due back in court on June 8.
