Federal prosecutors in the Southern District of New York unsealed an indictment on April 23, 2026, charging U.S. Army Master Sgt. Gannon Ken Van Dyke, 38, of Fayetteville, North Carolina, with five counts arising from his alleged use of classified military intelligence to place winning bets on the prediction market platform Polymarket [1]. Van Dyke allegedly wagered approximately $33,000 and collected roughly $409,881 in profits by exploiting advance knowledge of a covert operation [1][2]. He was arrested and released on a $250,000 bond [1].
The charges, filed by the U.S. Attorney's Office for the Southern District of New York, include unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud, and an unlawful monetary transaction [1]. The Commodity Futures Trading Commission filed a parallel civil complaint the same day, asserting jurisdiction over prediction market contracts as commodity instruments [1][3]. The conduct at issue centers on Operation Absolute Resolve, a U.S. military operation executed on January 3, 2026, that resulted in the capture of Venezuelan President Nicolás Maduro [2][3]. Van Dyke allegedly participated in the planning and execution of that operation and placed his bets before the outcome was publicly known [1][2].
The prosecution marks the first time federal authorities have brought criminal charges alleging insider trading on a prediction market using classified government information [2]. Polymarket, a crypto-based platform incorporated offshore but accessible to U.S. users, has grown substantially as a venue for wagering on geopolitical and electoral outcomes. The CFTC has previously asserted regulatory authority over certain prediction contracts, and its parallel civil action signals that agency's intent to treat information-based manipulation on such platforms as a cognizable commodities violation [1][3]. U.S. Attorney Jay Clayton and Deputy Attorney General Todd Blanche are among the senior officials associated with the case [1].
Van Dyke has not entered a plea. The indictment stands as an accusation, and he is presumed innocent. The dual-track structure, criminal charges in federal district court alongside a CFTC civil enforcement action, gives prosecutors and regulators independent remedial paths. Sentencing exposure on the combined counts is substantial, and the commodities fraud charge in particular carries significant statutory penalties. The case is expected to draw scrutiny from the prediction market industry and from legal commentators focused on the intersection of national security law and financial regulation.
