Hackers Take Some Polymarket User Funds, Exchange Refers Case to U.K. Authorities

Prediction market Polymarket says hackers have stolen funds from some of its users. The company has referred the matter to U.K. authorities, according to the report this article is based on.

The incident coincided with an outage on the platform. That timing matters because Polymarket had been preparing for a surge in activity tied to the U.S. midterm elections, when traders typically pile into election contracts and the site is under its heaviest load. An outage at that point puts pressure on the company to show users their money and their trades are secure.

The source material does not say how many users were affected, how much was taken, or how the attackers gained access. Those details will determine how serious the damage is and whether the losses can be recovered. Until the company publishes more, the most useful thing for users is to check their account activity and treat any unexpected withdrawal or login as a security issue.

Investors and users should watch for a fuller account from Polymarket, including any compensation plans and a timeline for restoring service before the election period.
