According to data from blockchain analytics company Bubblemaps, six Polymarket accounts profited approximately $1.2 million after accurately predicting the U.S. attack on Iran on February 28. Most wallets topped up within 24 hours of the attack and bought "Yes" shares just before reports of the explosion emerged. One account purchased over 560,000 shares at a price of $0.108 each, netting nearly $560,000 in profit. Previously, competitor platform Kalshi recently took enforcement action, and U.S. regulators (including the U.S. Commodity Futures Trading Commission CFTC) are considering regulating insider trading on prediction markets.
