Stanford Study Uncovers $8.2M Rigged Bitcoin Bets on Polymarket
A groundbreaking study from Stanford and Singapore Management University has exposed systematic settlement manipulation within Polymarket’s Bitcoin betting products. A small group of sophisticated traders successfully extracted $8.2 million by exploiting the final seconds of five-minute contracts.
By aggressively pushing the spot price on Binance just before settlement, these actors were able to manipulate the outcome of high-speed prediction markets. This revelation underscores a significant security flaw in how decentralized prediction platforms rely on external price feeds for contract resolution.
The method was precise: traders manipulated the spot price on Binance during the final 10 seconds of five-minute Bitcoin contracts. This micro-manipulation ensured the settlement price favored their specific bets, effectively rigging the outcome. The study serves as a stark warning regarding the risks of price manipulation in crypto-based prediction markets and the necessity for more robust settlement mechanisms.
