Polymarket announced on its official Discord that it has identified a situation regarding the "Ukrainian Rare Earth Market" prediction event. The resolution of this market contradicts the expectations of Polymarket users. Polymarket stated that since this is not a market failure, there will be no refunds. Meanwhile, after negotiations with the UMA team, Polymarket will establish systems and monitoring to ensure that such situations do not recur. According to previous community news, a user manipulated the results of the "Ukrainian Rare Earth Market" prediction event on Polymarket by hijacking the oracle UMA.
