Polymarket says hackers stole users’ funds

Polymarket said it is refunding users whose funds were stolen after a third-party breach. The company did not provide additional details in the brief report about the attacker, affected users, or total losses.

The incident underscores how crypto and prediction market platforms remain exposed to risks beyond their own core systems. As platforms handle more user funds, pressure will grow for stronger vendor security controls and clearer breach disclosures.
