Some users of prediction market platform Polymarket's international exchange had funds stolen from their accounts due to a hack an unnamed third-party provider.
Polymarket has contacted law enforcement and pledged to reimburse any trader impacted. It's unclear how many users were impacted. The U.S. platform was not comprimised.
Traders first reported on social media platforms that they were seeing unauthorized withdrawals from their accounts on Thursday afternoon. In response, the company halted trading on its international platform.
Polymarket said that it has fixed the issue on its end, and that trading resumed at 3:00 p.m. ET.
A Polymarket spokesperson said it has referred the matter to U.K. law enforcement, as that is the country of operation for the third-party provider.
