Nine anonymous crypto wallets now control how disputed bets are settled on Polymarket, according to Bloomberg. These whales have the final say on billions of dollars in prediction market bets. Whenever there is a disagreement about a result, these wallets decide the outcome for thousands of contracts.

How does voting power concentrate in Polymarket disputes?
Polymarket relies on UMA’s Optimistic Oracle to settle disputes when users challenge market results. To vote, users need to stake UMA tokens. In the past year, almost 2,000 contracts about elections, world events, and other topics have needed this kind of resolution.
As more people use the platform, voting power has become even more concentrated. For example, in April, 230 contracts worth over $1 billion needed outside review, compared to just 79 contracts six months before. Now, these nine big wallets often vote together to influence results, which makes people question if the system is really decentralized.
Polymarket is under increasing pressure to clarify its contracts, but the platform has not yet upgraded its system to address these issues. The planned changes would help spread out voting power and make dispute resolution fairer. However, Polymarket has repeatedly put off these upgrades.
Critics warn that without changes, a small group of wealthy users can decide who wins or loses. This puts everyday traders at risk and, if many people bet on public events, only a few hidden wallets decide who gets paid.
Regulatory challenges for Polymarket
Recently, House Oversight Chair James Comer launched an insider trading investigation into prediction platforms Kalshi and Polymarket, demanding internal transaction records by June 5.
The probe was moved by suspiciously timed bets placed hours before classified U.S.-Israeli military operations against Iran, and a separate case involving a U.S. soldier charged with using classified information to earn over $400,000 on Polymarket
Regulators globally, particularly the US Commodity Futures Trading Commission (CFTC), maintain a strict stance on derivative-like betting markets.
Meanwhile, Indonesia’s Ministry of Communication and Digital Affairs has blocked access to Polymarket, saying the platform is an illegal online gambling site. The decision came after users were able to place bets on whether President Prabowo Subianto would leave office before his term ends in 2029.
