According to Bloomberg, the rulings on controversial contracts on Polymarket are being dominated by a small number of UMA holders. Bloomberg's statistics show that among over 6,400 addresses that participated in Polymarket's controversial ruling votes over the past three years, only 9 large wallets contributed about half of the UMA voting power and sided with the winning side in almost all disputes.
In April 2026, about 230 contracts with a total trading volume exceeding $1 billion entered the controversial ruling process, accounting for less than 1% of all contracts on Polymarket, but the frequency of disputes increased with the trading scale. Some traders criticized that this mechanism effectively grants anonymous whales "fact-determining power" driven by economic interests, while Polymarket and Risk Labs, responsible for UMA, had originally promised to improve the relevant processes, which has now been shelved.
