In January 2025, KuCoin's operating company pleaded guilty in the Southern District of New York to operating an unlicensed money transmitting business. Prosecutors said KuCoin never registered with FinCEN and, for years, ran without a working anti-money-laundering or know-your-customer program, despite serving around 1.5 million US customers and earning at least $184.5 million in fees from that business. KuCoin did not introduce KYC checks until August 2023.
The company agreed to pay penalties totaling about $297.4 million, and its co-founders each agreed to forfeit $2.7 million personally and step away from management. As part of the settlement, KuCoin agreed to exit the US market, and in March 2026 a federal court approved a CFTC consent order that converted the withdrawal into a permanent bar on serving US customers. In plain terms: KuCoin admitted to running an unlicensed, poorly policed money-transmission business in the US for years, paid close to $300 million to settle it, and is now permanently locked out of the US market.
