Polymarket suffered the most severe oracle manipulation attack since the establishment of the project, resulting in a prediction pool with a bet size exceeding $7 million giving incorrect result judgments. In the end, users who bet on the correct result suffered heavy losses, while users who bet on the wrong result took away all the funds in the prize pool. Surprisingly@ Polymarket officials announced on Discord this morning that they have been informed of the unexpected situation, but are unable to issue refunds to users.
