The Department of Justice unsealed an indictment on April 23, 2026, charging Master Sergeant Gannon Ken Van Dyke, 38, a U.S. Army Special Forces soldier, with five counts arising from his alleged use of classified military intelligence to place winning wagers on the prediction market platform Polymarket [1]. The charges 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]. Van Dyke pleaded not guilty at his arraignment on April 28 [3].
According to the indictment, Van Dyke possessed classified knowledge of Operation Absolute Resolve, the January 2026 U.S. military operation that resulted in the capture of Venezuelan President Nicolás Maduro [1][2]. Prosecutors allege he used that foreknowledge to invest approximately $33,034 on Polymarket, a blockchain-based prediction market, generating roughly $409,881 in profit once the operation became public [1][2]. The commodities fraud count is grounded in the Commodity Exchange Act, under which the Commodity Futures Trading Commission has asserted regulatory jurisdiction over prediction market contracts [1]. The U.S. Attorney's Office for the Southern District of New York, led by U.S. Attorney Jay Clayton, is prosecuting the case [1]. Van Dyke is represented by defense attorney Mark Geragos [3].
The prosecution marks the first federal criminal case in which the government has applied insider-trading-style liability to a prediction market platform [1]. While the CFTC has previously regulated certain event contracts, federal prosecutors had not before this case used commodities fraud statutes to target a defendant who allegedly exploited classified government information to wager on geopolitical outcomes. The theory tracks the same logic courts have applied to securities insider trading: material, nonpublic information obtained through a position of trust cannot be converted to personal financial gain [2].
Van Dyke's arraignment entered a not-guilty plea, and the case now proceeds toward pretrial litigation in the Southern District of New York [3]. Defense counsel has not publicly detailed a trial strategy. Key legal questions ahead include whether prediction market contracts qualify as commodities under the CEA, the scope of the government information statutes charged, and whether classified-information procedures under the Classified Information Procedures Act will govern discovery [2][3]. A conviction on all counts could result in a substantial custodial sentence, and the case is expected to draw close attention from the CFTC, prediction market operators, and national security practitioners.
