U.S. Army Special Forces Sergeant Gannon Van Dyke has been indicted for allegedly using classified military information to codedly predict the arrest of Venezuelan President Nicolás Maduro on the prediction market platform Polymarket, illegally profiting over $400,000. Notably, Van Dyke attempted to open an account on the competing platform Kalshi, but was rejected due to failed identity verification and KYC checks. Polymarket stated that it proactively reported his suspicious trading activity to law enforcement and fully cooperated with the investigation. This case is considered the first major criminal case of insider trading in the prediction market sector, and has once again raised market concerns about the risks of insider trading on prediction platforms.
