The nearly hour-long suspension of Polymarket's international platform ended at 3 p.m. ET once the vendor compromise was contained. Analytics firm DebugBear confirmed on social media that it suffered an ongoing security incident, which attackers used to compromise platform funds. Blockchain analysis from Arkham indicated that approximately $2.65 million in cryptocurrency was drained during the breach. This security disruption adds friction as the high-volume platform also navigates regulatory oversight battles and internal election-betting probes.
