According to Bloomberg, about 230 Polymarket contracts with more than $1 billion in trading entered UMA dispute resolution in April 2026, while planned reforms by Polymarket and Risk Labs were shelved.
Bloomberg reported that nine large wallets accounted for about half of the voting power used in UMA dispute rulings tied to Polymarket, a crypto-based prediction market. Around 230 Polymarket contracts entered dispute resolution in April 2026, representing less than 1% of all contracts but more than $1 billion in total trading volume. Bloomberg also said planned process reforms by Polymarket and Risk Labs were shelved. The report highlights both the concentration of influence in oracle-based dispute systems and the large economic value attached to a relatively small share of disputed markets.
