Polymarket Is Returning $3.9 Million After International Platform Attack

Polymarket is returning $3.9 million after an Oct. 29 attack on its international platform drained user wallets and disrupted trading, with the payout covering stolen funds and losses tied to a temporary halt. The company’s Oct. 30 update divided the total into $2.7 million for drained wallets and $1.2 million for pause-related losses. It said 95% of wallets affected by the hack had been fully refunded by that afternoon. Users who believe their reimbursement is wrong can ask Polymarket to review it. Polymarket said attackers changed a performance-monitoring script supplied by an unnamed third-party provider.
