UMA vote backs Polymarket No settlement in Strategy bitcoin sale as users accuse platform of changing rules

Crypto Briefing reported that users accused Polymarket of changing its settlement rules to void a winning bet on whether Strategy sold bitcoin before the market’s deadline, warning the move could undermine trust in prediction markets ^[1].

Polymarket referred the dispute to UMA governance; UMA voters ruled that Strategy’s June 1 disclosure applied to the June contract and the market was finalized with a “No” outcome after 98.6% of UMA voting power backed the decision, despite Strategy saying it sold bitcoin during the final week of May ^{[2] [3] [4]}.

The contested market was settled via on-chain governance, but commentators cautioned the episode could deter participation and affect the integrity of prediction markets ^{[4] [1]}.
