The platform, which relies on UMA’s Optimistic Oracle for settling markets, came under fire after traders discovered that a single entity had cast 5 million UMA tokens to sway the outcome.
According to a report by Colin Wu, the whale placed last-minute votes through three separate accounts to influence the result of a poll regarding former President Donald Trump’s alleged Ukrainian mineral deal.
The wallet’s actions accounted for 25% of the total votes, tipping the scales and enabling them to profit from a disputed resolution.
More than $7 million was at stake in the market. Many traders who bet against the outcome lost thousands after the manipulated vote forced an artificial result.
Traders Demand Refunds, Polymarket Stands Firm
The manipulated resolution sparked outrage, with Polymarket users calling for refunds. Many traders argued there was no verifiable proof that Trump had signed a deal with Ukraine, making the final result inaccurate.
Despite the uproar, Polymarket refused to issue refunds, claiming the situation did not qualify as a market failure.
Users took to X to vent their frustrations. One trader accused Polymarket of enabling rigged resolutions, pointing out that the system allowed wealthy participants to buy influence and skew results.
“The resolution is done through a vote of owners of the crypto UMA, and one person purchased ~$5 million of this coin, giving them near veto power,” the trader wrote.
Another user warned against trading on Polymarket, arguing that whales could manipulate outcomes to serve their interests.
Polymarket’s Rise and a Growing Credibility Issue
Polymarket has seen a surge in popularity, especially during the recent U.S. presidential election, which saw Donald Trump secure a historic second term. The platform gained attention from high-profile figures, including Elon Musk and Trump himself.
Despite its hype, the latest controversy raises questions about the integrity of Polymarket’s resolution process.
While the platform has vowed to address vote manipulation concerns, traders remain skeptical about the fairness of its governance system.
