Polymarket users cry foul after Strategy sale market resolves to ‘no’

Summary

Polymarket’s market on whether Strategy sold Bitcoin by May 31 resolved to “No” after two dispute rounds, even though Strategy later disclosed it sold 32 BTC during the market period. UMA token holders overwhelmingly backed the “No” outcome, with 98.6% of 607 voters in favor. Polymarket said only information confirmed within the market’s timeframe counted, so the later filing did not qualify. The outcome intensified criticism of Polymarket’s UMA-based, token-weighted dispute system, where large token holders have outsized influence. Critics argued the market should have followed when the sale happened, not when it was publicly confirmed. A trader reportedly lost $500,000, and more than $80 million was wagered on the contract. The dispute followed other contentious resolutions and renewed concerns about whale manipulation, governance attacks, and prediction-market integrity.
