Why a $150M Polymarket bet could pay the side that appeared to lose
A nearly $150 million Polymarket market over whether Strategy would sell any Bitcoin by May 31 turned chaotic after the company’s June 1 8-K confirmed it had sold 32 BTC during the deadline window. Traders who thought that proved a “Yes” win were denied payouts because Polymarket said only public confirmation by May 31 counted, despite the contract wording and the market staying open after the sale occurred. Critics called this a trap and accused the platform of hiding an unwritten rule. The dispute highlights a deeper problem in Polymarket’s resolution system: contested markets are decided through UMA token voting, where large holders can influence outcomes and resolution can diverge from objective facts. Analysts say this creates vulnerability to manipulation and conflicts of interest. The controversy arrives as prediction markets like Polymarket and Kalshi surge in volume and gain institutional ties, even as their dispute mechanics remain experimental and fragile.
