U.S. Army soldier Gannon Ken Van Dyke is the defendant in the Polymarket insider trading case, and a tentative trial date was set for December 7 in Manhattan. Van Dyke, 38, pleaded not guilty in April and faces five federal charges: three counts of violating the Commodity Exchange Act, wire fraud, and making an unlawful monetary transaction. Prosecutors allege he placed 13 bets on Venezuela-related outcomes over seven days beginning in late December and netted $410,000 from an initial $33,000 investment.
Gannon Ken Van Dyke is charged in federal court with five criminal counts: three counts of violating the Commodity Exchange Act, one count of wire fraud, and one count of making an unlawful monetary transaction. He pleaded not guilty in April to the five federal crimes, including commodities fraud. Prosecutors have included the commodities-related counts among the charges brought against him.
Following his arraignment, Van Dyke was released on a $250,000 personal recognizance bond. Prosecutors allege Van Dyke attempted to delete his Polymarket account to cover his tracks. The defense plans to file a motion to dismiss the case by the end of next month. The matter is described as the government’s first insider trading case involving a prediction market in the Southern District of New York.
The investigation into the Polymarket wagers was triggered by inquiries from the House Oversight Committee. Committee Chair James Comer requested documents and internal communications from Polymarket related to wagers on Venezuela’s president, and those requests prompted further scrutiny of the platform’s activity. The committee’s inquiry focused on records and communications that could shed light on how specific wagers were placed and reported.
The Commodity Futures Trading Commission filed its own complaint separately from the other actions related to the matter. CFTC Chair Mike Selig said, “Anyone who engages in fraud, manipulation, or insider trading in any of our markets will face the full force of the law,” and the Commission emphasized enforcement against fraud and insider trading in prediction markets. Investigators have identified the activity under review as centering on wagers tied to the January removal of Nicolás Maduro. The CFTC complaint was lodged independently of the committee’s document requests and the criminal proceedings.
Van Dyke allegedly attempted to delete his Polymarket account to cover his tracks. He was released on a $250,000 personal recognizance bond after arraignment. The attempted account deletion is an allegation raised by prosecutors. During the hearing, Van Dyke arrived wearing a dark suit jacket, a black shirt, and no tie.
The matter has been described as the government’s first insider trading case involving a prediction market in the Southern District of New York. That description frames the case as a novel enforcement action in prediction market oversight.
