Polymarket suspends trading after third-party breach drains accounts

Polymarket has suspended trading after users reported their accounts being drained, with the prediction platform attributing the incident to a breach at one of its third-party providers. The company said a provider was compromised, but disclosed no details on which provider, how much was taken, or how many users were affected.

• Trading remains halted while the incident is investigated; no restoration timeline has been given.
• The breach adds to a rough stretch for Polymarket, which is already under CFTC scrutiny over its U.S. platform compliance and recently fired its CMO after an internal misconduct probe.
