Polymarket temporarily suspended trading on its international platform on Oct. 29 after reports that users’ accounts had been drained and positions closed without authorization, in a security incident later linked to a compromised third-party provider. The disruption lasted about an hour, with trading eventually resuming after the platform said its systems were operational. However, the extent of the reported losses, the number of affected users and the precise cause of the fund compromise remained unclear as the company launched an investigation.
Polymarket did not immediately provide a detailed public accounting of the cause or scope of the reported fund drain at the time of the initial reports. Details on the amount of funds affected, the mechanism of the reported drain, and the number of users impacted were not immediately disclosed in the early coverage [1][2].
