In April 2026, U.S. Army Special Forces Master Sergeant Gannon Ken Van Dyke was charged for allegedly profiting over $400,000 on bets placed on an offshore cryptocurrency-based prediction platform using classified information related to a military operation targeting former Venezuelan President Nicolás Maduro. The prosecution of Van Dyke reflected the government’s position that prediction markets are subject to the Commodity Exchange Act’s (CEA) anti-fraud and insider trading prohibitions.
Less than six weeks later, federal prosecutors have filed a second insider trading claim involving prediction markets–this time alleging use of confidential corporate data on Polymarket, the world’s largest online prediction marketplace.
