Bloomberg: Nine Whale Wallets Hold Sway Over Polymarket's Billion-Dollar Dispute Resolutions

PANews, May 26 — Bloomberg reports that disputed contract outcomes on Polymarket are increasingly being decided by a small group of UMA token holders. Bloomberg data show that out of more than 6,400 addresses that have taken part in dispute-resolution voting on Polymarket over the past three years, just nine large wallets controlled about half of all UMA voting power and backed the winning side in nearly every dispute. In April 2026, roughly 230 contracts — with combined trading volume topping $1 billion — entered the dispute-resolution process. That figure represents less than 1% of all Polymarket contracts, though disputes tend to become more common as trading volume rises. Some traders argue the system effectively gives anonymous whales financial incentives to determine "facts," while earlier pledges by Polymarket and Risk Labs to improve the process have been paused.
