Bloomberg has reported that nine whale wallets have dominated the decision-making process in Polymarket's dispute resolutions, controlling nearly half of the UMA voting power. Over the past three years, these wallets have consistently sided with the winning outcomes in disputes. In April 2026, approximately 230 contracts, with a total transaction value exceeding $10 billion, entered the dispute resolution process. This represents less than 1% of all Polymarket contracts, but the frequency of disputes increases with transaction size. Critics argue that this system grants anonymous whales undue influence, while promised improvements to the process by Polymarket and Risk Labs have been shelved.
