Polymarket Sets $3.9 Million in Compensation After Script Attack

Polymarket said it will compensate traders $3.9 million after an Oct. 29 script compromise on its international platform, covering positions sold through user sessions and some trading-pause losses. The prediction-market platform’s postmortem, published Oct. 30 at 4:07 p.m. ET (20:07 UTC), split the amount into $2.7 million tied to the attack and $1.2 million for pause-related losses. The total is a compensation figure, not a confirmed estimate of funds taken from traders. Polymarket described an attacker substituting a third-party monitoring script loaded by Polymarket.com.
