In September 2023, US federal prosecutors indicted KuCoin CEO Johnny Lyu and CFO Ke Tang on charges of willful failure to implement anti-money laundering controls and conspiracy to commit money laundering. The indictment alleged the exchange processed transactions from sanctioned jurisdictions and did not conduct adequate customer verification, according to court filings.
Neither executive has been arrested or appeared in US court. KuCoin has not been formally charged as an entity, and the exchange maintains it complies with applicable laws where it operates. The company did not respond to requests for comment on the allegations or their operational impact.
Despite the US case, KuCoin reported $4.6 billion in daily trading volume as of early 2024, making it the eighth-largest exchange globally by volume. The platform lists over 1,000 trading pairs and reports $3.24 billion in verified exchange reserves. US-based users cannot access margin trading or derivatives on KuCoin, though spot trading remains available to some accounts depending on state residency.
European licensing shift
KuCoin has pursued regulatory approval in Europe over the past two years. The exchange obtained a Markets in Crypto-Assets Regulation (MiCA) license in multiple EU member states, allowing it to offer services including spot trading and staking to European customers. This geographic pivot reflects a broader industry pattern: exchanges facing US enforcement action often expand licensing in jurisdictions with clearer rulebooks.
The MiCA framework requires exchanges to maintain segregated customer assets, implement transaction monitoring, and report suspicious activity. Compliance with these rules does not resolve the outstanding US indictment.
What US users should know
American customers can still access KuCoin's spot trading product, but the exchange restricts access to leverage and derivatives accounts. Some states have additional restrictions. The indictment does not prevent the platform from operating, but it creates legal uncertainty for the company and raises questions about future US regulatory action.
The reserve figure KuCoin cites (audited to some extent by third parties) is a standard metric exchanges use to demonstrate liquidity, though audits of crypto exchange reserves vary widely in scope and methodology. No single audit guarantees solvency or customer fund safety.
