Polymarket Halts International Exchange Trading After Third-Party Provider Breach, Stolen Funds Reported

Polymarket temporarily halted trading on its international exchange on Thursday after reporting that a third-party software provider was compromised, following user complaints about stolen funds on the platform's Discord chatroom. The prediction market did not disclose how users were affected, identify the provider, or specify what caused the outage. The company said anyone impacted "will be made whole" and that it had referred the incident to law enforcement authorities in the UK. Trading resumed after about an hour, Polymarket said in a follow-up post.
