Polymarket fine print voids student's $35K bet
Hunter Guo, a 20-year-old King's College London student, lost roughly $35,000 in bets on Polymarket after the platform's fine-print terms voided what appeared to be a winning position, according to a Wall Street Journal report. Guo believed he held a near-guaranteed win, but Polymarket changed its contractual terms in a way that wiped out his wager. The incident highlights how prediction market platforms can alter contract details to nullify apparent victories, even after traders have taken positions. Both Bitget.com and MSN.com reported that the fine-print modification transformed the student's seemingly safe bet into a total loss, drawing attention to the enforceability and transparency of terms-of-service provisions on crypto-based prediction markets.
Polymarket's ability to retroactively amend contract terms and zero out customer positions gives CFTC and state attorneys general fresh ammunition to argue that prediction-market fine print deserves heightened disclosure scrutiny. Any regulatory rulemaking or settlement that follows will force the platform to pre-publish term-change protocols or forfeit the flexibility it just exercised against Guo.
