Polymarket confirmed that a third-party vendor compromise allowed hackers to inject malicious code into its website for some users, resulting in stolen cryptocurrency funds. The company stated it has contained the incident and is contacting affected victims to refund them in full.
TechCrunch reported that Polymarket spokesperson Connor Brandi confirmed the breach led to users’ funds being stolen but declined to provide further details or answer specific questions.
Blockchain monitoring firm PeckShield reported on X that a phishing campaign targeted Polymarket users and estimated that hackers stole around $3 million worth of cryptocurrency. A blockchain analyst reported similar losses and stated that the funds were taken from more than 11 victims. Two people on social media claimed in recent days that their Polymarket funds had been stolen.
Polymarket offers users the possibility of being paid in cryptocurrency. The incident follows an earlier report on Sunday that Polymarket paid online creators to post deceptive videos showing fake wins on lucrative bets. In response to that report, the company said it would audit its promotional content.
