A U.S. Army Special Forces master sergeant, Gannon Ken Van Dyke, was charged by federal prosecutors for using classified information to profit from bets on Polymarket regarding a military operation to capture Nicolás Maduro. Van Dyke allegedly bet approximately $33,000 on outcomes related to the Venezuela operation, eventually profiting around $409,881 after US special forces apprehended Maduro. He then attempted to conceal his identity and withdraw funds.
In a separate but related development, a KPMG employee, who had access to confidential information about a merger between two major companies, also allegedly made profitable bets on Polymarket. While specific details of the KPMG case are still emerging, it highlights the broader concern that prediction markets are being exploited for insider trading beyond military secrets. Polymarket, a popular prediction platform with billions in weekly trading volume, has recently come under scrutiny.
The Anti-Corruption Data Collective identified 152 accounts that allegedly profited about $8 million on war markets, including those related to the Iran war, exhibiting hallmarks of insider activity such as remarkably well-timed bets from new wallets with long-shot odds and a 97% win rate. Polymarket itself has referred dozens of these suspicious accounts to the Justice Department for investigation. These revelations underscore a growing concern among federal authorities about the misuse of confidential information on prediction platforms.
