Federal prosecutors in the Southern District of New York unsealed a five-count indictment on April 23, 2026, charging Army Master Sergeant Gannon Ken Van Dyke with using classified military information to place profitable trades on Polymarket, a cryptocurrency-based prediction market platform [1]. Van Dyke allegedly netted approximately $409,881 through contracts tied to a covert U.S. military operation [1]. The Commodity Futures Trading Commission filed a parallel civil enforcement action the same day [1].
The criminal charges span unlawful use of classified government information, commodities fraud, wire fraud, and money laundering [1]. According to the indictment, Van Dyke had access to nonpublic information about Operation Absolute Resolve, a classified mission resulting in the capture of Venezuelan President Nicolás Maduro [1]. Prosecutors allege he used that foreknowledge to purchase prediction-market contracts on the outcome before the operation became public, then collected winnings once the event resolved [1]. Polymarket operates on blockchain infrastructure and settles contracts in cryptocurrency, a structure that the CFTC has asserted brings such instruments within its regulatory jurisdiction over commodity interests [1].
The case is notable for its legal novelty. Prior insider-trading prosecutions have targeted equity and derivatives markets; this marks the first federal criminal charge alleging that a service member exploited classified national security information to trade on a prediction market [1]. Jay Clayton, U.S. Attorney for the Southern District of New York, announced the charges [1]. The FBI investigated the matter [1]. The parallel CFTC action indicates the government is pursuing both criminal accountability and civil disgorgement simultaneously, a posture consistent with the agency's recent efforts to assert enforcement authority over decentralized prediction platforms.
Van Dyke faces potential consecutive sentences on each count if convicted. The money-laundering charge, in particular, carries a statutory maximum of 20 years under 18 U.S.C. § 1956 and may be used to reach proceeds already moved or converted. The simultaneous civil action gives the CFTC an independent path to recover the alleged $409,881 in gains regardless of the criminal outcome. Defense counsel had not entered a public response as of the filing date.
The case is expected to draw scrutiny from legal practitioners and national security officials alike, as it raises unsettled questions about whether prediction markets constitute commodity markets under the Commodity Exchange Act and how classified-information statutes interact with financial fraud theories when the underlying asset is a geopolitical event contract rather than a traditional security.
