## Summary

Polymarket halted trading on its international platform while investigating a breach at a UK-based third-party vendor. The incident matters because traders’ accounts were drained, though the company said it would refund those affected and that its US platform was not impacted.

Blockchain analytics firm Bubblemaps estimated that about 700 users lost approximately $2.7 million. UK law enforcement was notified, and trading was paused for several hours. Polymarket operates a cryptocurrency-based international market and a separate federally regulated US exchange; the international platform also suffered a breach in June 2026, causing more than $2 million in losses.
