Polymarket Faces Criticism Over UMA Dispute in Zelenskyy Suit Market
Polymarket is under scrutiny after a controversial ruling on whether Ukrainian President Volodymyr Zelenskyy wore a suit, raising doubts about the platform’s decentralized dispute resolution.
The resolution was handled by UMA, a decentralized oracle protocol that settles disputes through token-holder voting. However, critics say UMA’s system allows large token holders to dominate decisions, compromising decentralization.
Controversial Ruling Sparks Backlash
Despite reports from outlets like the BBC and New York Post confirming Zelenskyy wore a suit, UMA ruled “No” on a nearly $200 million market asking if he did. This left many users frustrated and distrustful.
Trader Highlights Flaws in Voting Incentives
Top Polymarket trader RememberAmalek argues that UMA’s voting model pressures participants to vote with the majority to avoid losing staked tokens, rather than on facts.
RememberAmalek, known for making over $1 million on Polymarket, including a big win on the New York mayoral primary, calls UMA’s governance “susceptible to manipulation.”
Whale Influence Raises Decentralization Concerns
UMA’s system penalizes voters who disagree with the consensus, encouraging conformity. Large token holders (“whales”) control about 95% of UMA tokens, giving them outsized influence.
Betting on Outcomes Instead of Reality
RememberAmalek admits he now bets based on expected rulings, not actual events, reflecting a fundamental flaw in UMA’s model.
Calls for Centralized Resolution
Despite advocating decentralization, RememberAmalek believes Polymarket should take over dispute resolution to improve fairness and trust.
He concludes: “This isn’t decentralized.”
