Nine whale wallets reportedly steer Polymarket dispute outcomes

ME News reported on May 26 (UTC+8) that Polymarket's dispute resolution votes are increasingly concentrated among a small group of UMA holders. Data show that out of more than 6,400 addresses that have taken part in Polymarket dispute-resolution voting over the past three years, just nine whale addresses control about half of total UMA voting power and have backed the eventual winning outcome in nearly all disputes. In April 2026, roughly 230 contracts with combined trading volume above $1 billion entered the dispute process. While this was less than 1% of all Polymarket contracts, disputes were more common among higher-volume markets. Some traders argue the setup effectively gives anonymous whale holders incentive-driven, de facto decision-making power. Proposed improvements previously pledged by Polymarket and Risk Labs, the team behind UMA, have reportedly been paused. (Source: BlockBeats)
