Polymarket users reportedly profited from insider information regarding the arrest of Venezuelan President Nicolás Maduro by U.S. forces. According to Lookonchain, three addresses on the prediction market platform placed bets on Maduro's removal days before the event, earning a total of $630,400. The most significant address, 0x31a5, invested $34,000 and gained $409,900, betting on the U.S. military action before it was publicly known. The U.S. military operation to capture Maduro occurred on January 3, 2026, but insiders began placing bets as early as December 27, 2025. This incident highlights the potential for prediction markets like Polymarket to be used for insider trading, as they offer anonymity and lack strict KYC requirements. The event has sparked discussions about regulatory measures to prevent such activities, with U.S. Representative Ritchie Torres proposing legislation to restrict insider trading in prediction markets.
