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.
