A US Army Special Forces sergeant has become the first person criminally charged for alleged insider trading on a political prediction betting platform. The soldier reportedly profited heavily by placing wagers based on classified military operation details.
The serviceman, identified as Staff Sergeant Gannon Ken Van Dyke, participated in planning and executing the operation to capture Venezuelan President Nicolás Maduro last December. Shortly after joining the mission, he created an account on Polymarket, a political forecasting betting site.
Over 13 separate bets placed on outcomes including US military entry into Venezuela and Maduro’s removal, Van Dyke turned approximately $33,000 into roughly $410,000—a staggering return of more than twelve times his initial investment.
According to federal prosecutors, the sergeant attempted to destroy evidence by transferring most of his winnings to cryptocurrency storage accounts using pseudonymous email addresses. He also requested account deletion in early January, falsely claiming he’d lost access credentials.
This marks the Justice Department’s inaugural prosecution applying insider trading laws to prediction market platforms—a landmark case that could open the door to further investigations.
Suspicions of similar activity have emerged surrounding other major events. Hours before the President announced a ceasefire with Iran earlier this month, at least 50 newly created Polymarket accounts placed concentrated bets on that exact outcome. One account established just 12 minutes before the betting option appeared wagered over $31,000 and collected $48,500.
During the recent Iran conflict, multiple suspicious betting patterns raised red flags. These incidents have prompted bipartisan Congressional action, with lawmakers from both parties co-sponsoring legislation to formally extend insider trading prohibitions to prediction betting markets.
The case represents growing concerns about the intersection of classified government information and unregulated betting platforms, where sensitive details about military operations or policy decisions could potentially be exploited for financial gain.
