According to Odaily, Polymarket announced on its official Discord that it has identified issues related to the 'Ukraine Rare Earth Market' prediction event. The resolution of this market did not meet the expectations of Polymarket users. Polymarket clarified that since this was not a market failure, refunds will not be issued. In collaboration with the UMA team, Polymarket plans to establish systems and monitoring measures to prevent similar incidents in the future. Previously, community reports indicated that a user manipulated the outcome of the 'Ukraine Rare Earth Market' prediction event on Polymarket by hijacking the UMA oracle.
