What happened
Polymarket's international platform suspended trading on 29 October 2026 after a compromised third-party provider led to unauthorised withdrawals and closed positions. Reporting links the incident to DebugBear, a website performance monitoring service, though Polymarket's statement did not name the vendor. Outside estimates cited by CNBC put withdrawals at at least $2.7 million across 710 wallets, and the company has pledged to make users whole.

What to do
- If you have an account with the company, change that password, and anywhere you used the same one.
- Turn on two-step sign-in where you can.
- Expect scam emails and texts that mention the breach: contact the company yourself, not through links.
