POLYMARKET HALTS TRADING AFTER THIRD-PARTY SECURITY BREACH! Prediction market platform Polymarket temporarily suspended trading after discovering a security incident involving one of its third-party service providers. The incident triggered a major outage in its Predictions Trading API, forcing the platform to switch to "cancel-only" mode. This meant users could cancel existing orders, but placing new orders or executing trades was temporarily unavailable. The disruption came after several users claimed that funds had disappeared from their accounts, with some alleging that their positions were sold without authorization. Blockchain analytics reports also identified a suspected attacker wallet holding approximately $2.65 million worth of POL tokens following the incident.
