Prediction Market Giant Polymarket Hit by Cyberattack, with Company Confirming User Funds Stolen — Here Is What We Know
Polymarket said it contained the breach and is refunding affected users in full after hackers stole about $3 million in cryptocurrency.
- On Thursday, Polymarket confirmed that a third-party vendor compromise allowed hackers to inject malicious code into its website, resulting in an estimated $3 million in losses for users.
- The breach follows a Wall Street Journal investigation revealing Polymarket paid online creators to post deceptive videos showing fake wins, using "near-perfect copies of its website" for simulated trades.
- According to blockchain monitoring firm PeckShield and SpecterAnalyst, the attacker drained funds from more than 11 victim wallets holding PUSD, swapping stolen assets for ETH before consolidating proceeds.
- Polymarket head of experience William LeGate confirmed the company "contained" the incident and is contacting affected victims, "refunding them in full" to address losses.
- These security concerns contrast sharply with recent praise for Polymarket's ad campaign featuring music producer Rick Rubin, which earlier this week earned endorsement from CNBC's Andrew Ross Sorkin.
