In the Polymarket illegal gains of $400,000, a US soldier was once rejected from opening an account by Kalshi

Odaily News: U.S. Army Special Forces Command Sergeant Major Gannon Van Dyke has been charged with illegally profiting over $400,000 by allegedly using classified military intelligence on the prediction market platform Polymarket to speculate on the arrest incident of Venezuelan President Nicolas Maduro. Notably, Van Dyke had previously 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 activities to law enforcement authorities and fully cooperated with the investigation. This case is considered the first major insider trading criminal case in the prediction market sector, once again drawing market attention to the risk of insider trading on prediction platforms.
