According to Blockonomi, Polymarket restored trading on its international platform following a security breach at a third‑party vendor on October 29. Researchers identified malicious code in a website performance‑monitoring service as the source of the incident. Bubblemaps estimated that approximately $2.7 million was taken from around 700 users; Polymarket has not confirmed this amount. The company’s regulated platform, Polymarket US, remained unaffected by the breach aside from the need to address vendor security issues.
