Binance founder Changpeng Zhao has asked the U.S. Bankruptcy Court in Delaware to throw out a clawback suit filed by the FTX bankruptcy estate that seeks as much as $1.8 billion. In a motion submitted on Monday, Zhao’s lawyers said the court lacks personal jurisdiction because the former exchange chief, who now lives in the United Arab Emirates, was improperly served and has no substantive ties to Delaware. The estate sued Zhao, Binance and several former executives in November 2024, alleging that a July 2021 deal in which FTX bought back a roughly 20% stake held by Binance was funded with customer assets misappropriated by Sam Bankman-Fried. The complaint seeks to recover about $1.76 billion to help repay creditors of the exchange, which collapsed in November 2022. Zhao contends he was only a nominal counterparty in the transaction and never received the assets in question. The filing further argues that U.S. bankruptcy statutes do not extend to the extraterritorial transfers at issue and that the estate’s constructive-fraud claims are blocked by safe-harbor provisions covering securities contracts. Two other former Binance executives moved last month to dismiss the same suit on similar grounds. Zhao stepped down as Binance chief executive after pleading guilty in a U.S. anti-money-laundering case that yielded a $4.3 billion settlement; he served a four-month federal sentence. Bankman-Fried, FTX’s founder, is serving 25 years for fraud and conspiracy. The Delaware court has not yet scheduled a hearing on Zhao’s motion.
