Polymarket issued goodwill compensation on Sept. 11 to users affected by an earlier CLOB (central limit order book) outage, with about 3,000 wallets receiving payments automatically. Users who believe they were affected but did not receive compensation can email detailed information before Sept. 18 for manual review. Polymarket’s status page said on Aug. 31 that a major trading API failure caused delayed responses when users checked unfilled orders.
