Polymarket insider trading trial set for Dec. 7 in Manhattan

A Manhattan federal court has scheduled a Dec. 7 trial for U.S. Army soldier Gannon Van Dyke in what prosecutors call the first U.S. insider trading case tied to a prediction market. The Polymarket insider trading allegations claim he used classified military intelligence related to a January operation involving Venezuelan President Nicolás Maduro to place profitable bets. Court filings say Van Dyke made 13 Venezuela-related Polymarket wagers over seven days in late December, turning about $33,000 into more than $410,000 profit. He pleaded not guilty in April and now faces three Commodity Exchange Act counts plus wire fraud and unlawful monetary transaction charges. The defense is expected to seek dismissal, with a motion reportedly planned by the end of next month, and prosecutors also allege he tried to delete his Polymarket account after settlement. Outside the criminal case, Polymarket faces mounting regulatory pressure. A House Oversight request targets documents and communications tied to the Maduro operation. South Korea has opened a related investigation into domestic users, and the U.S. CFTC has filed a civil complaint, with Chair Mike Selig warning of enforcement against fraud, manipulation, and insider trading in regulated markets. For crypto traders, this Polymarket insider trading case is a clear reminder that prediction-market activity can draw both criminal and civil enforcement—raising compliance and counterparty-risk premiums near-term.
