Polymarket faces scrutiny as soldier charged with insider trading on military secrets

Polymarket is facing intense regulatory and national security scrutiny following the insider trading prosecution of U.S. Army Master Sgt. Gannon Ken Van Dyke, who allegedly used classified details from the raid on Nicolas Maduro to net $404,000. New research from the Anti-Corruption Data Collective reveals that over 150 'Orca' wallets have similarly traded on military secrets, generating $8 million and attracting copycat bets from automated bots. In response, Polymarket CEO Shayne Coplan disclosed that the platform employs a former FBI staffer full-time to run custom surveillance software on its public, on-chain transactions.
