Polymarket suspends trading after third-party breach

2026-10-29 · 1 source · CoinDesk

In short

Polymarket said one of its outside service providers was hacked after users said their accounts were drained. The company then suspended trading.

This matters because users may have lost funds and the platform has paused activity while the breach is checked. The report does not say how many users were affected or how large the losses were.

What the reporting says

Polymarket said a third-party provider was breached after users reported their accounts were drained, according to the summary. The company responded by suspending trading, but the reporting does not identify the provider, the number of affected users or the size of the losses. The immediate consequence is a halt in trading while the security incident is investigated.

Why it matters

Polymarket suspended trading after saying a third-party provider was breached and users reported drained accounts. The report ties the action to a security incident involving an outside vendor, but it does not name the provider or quantify user losses. The immediate effect is negative for users and the platform’s operations while the incident is investigated.
