A federal grand jury in the Southern District of New York indicted Master Sergeant Gannon Ken Van Dyke, 38, of Fayetteville, North Carolina, on five counts arising from his alleged use of classified military intelligence to place winning bets on a prediction market [1]. The charges include unlawful use of confidential government information, theft of nonpublic government information, commodities fraud, wire fraud, and unlawful monetary transaction [1]. Prosecutors allege Van Dyke staked more than $33,000 on Polymarket and netted approximately $409,881 in profit [1][2].
The indictment centers on Operation Absolute Resolve, a U.S. military operation resulting in the capture of Venezuelan President Nicolás Maduro [2]. Van Dyke, an active-duty Army Special Forces soldier, allegedly had access to classified information about the operation and used that knowledge to bet on Polymarket contracts tied to Maduro's removal from power before the outcome became public [1][3]. Polymarket is a decentralized prediction market platform on which users trade on the probability of real-world events. The Commodity Futures Trading Commission, which regulates certain prediction market contracts, filed a parallel civil complaint against Van Dyke seeking disgorgement of profits and civil monetary penalties [1][2].
U.S. Attorney Jay Clayton of the Southern District of New York announced the charges, framing the case as a test of whether government insiders can exploit classified knowledge for personal financial gain in emerging financial markets [1]. The CFTC's simultaneous civil action signals coordinated enforcement across criminal and regulatory channels. Prosecutors in the Southern District of New York are handling the criminal case, while the CFTC action proceeds on a separate civil track [1][2]. Van Dyke faces substantial prison exposure on the fraud counts alone, with the unlawful monetary transaction charge carrying additional penalties tied to the size of the proceeds.
The case establishes what prosecutors and regulators are positioning as the first U.S. criminal prosecution for classified-information insider trading on a prediction market [1][3]. It raises unresolved legal questions about how existing commodities fraud and theft-of-government-property statutes apply to prediction market instruments, which occupy contested regulatory ground. The outcome of the criminal case, and whether the CFTC civil action proceeds to a contested hearing or settles, will shape enforcement expectations for both government personnel and prediction market operators [2][3]. Arraignment scheduling and Van Dyke's entry of a plea had not been publicly reported as of the indictment date.
