Polymarket’s third-party service provider was hacked early this morning, halting trading for approximately one hour.

According to Polymarket’s status page, at 2:05 AM Beijing Time on October 30, the platform switched to a cancel-only mode and suspended relay operations. About an hour later, Polymarket announced it had identified and fixed issues with its international site, stating that a third-party service provider had been compromised, the incident was referred to law enforcement, and affected users would receive full compensation. Trading resumed shortly after, and the status page marked the incident as resolved. Per Bubblemaps monitoring, over 700 users were impacted in this crypto theft, with stolen funds totaling roughly $2.7 million. This marks Polymarket’s third security incident of the year: In May, an internal operations wallet was hacked due to a six-year-old private key leak, leading to around $700,000 in losses; on June 25, a third-party vendor breach resulted in malicious script injection into the frontend, with approximately $3 million in user funds stolen (affecting fewer than 15 accounts), and the platform pledged full compensation. There is currently no evidence linking this incident to the Binance event.
