Summary
BitMEX, the crypto derivatives exchange operated by HDR Global Trading Limited, faces a proposed class-action filed July 23, 2026 in the U.S. District Court for the Southern District of New York alleging systematic liquidation fraud and insider trading spanning at least eight years. Plaintiffs BKX Services Inc. and David Namdar allege BitMEX operated a secret internal trading desk with privileged 'god access' to private customer position data, enabling it to front-run customers during engineered server freeze events, and that the exchange retained 622.66 BTC (approximately $40.7 million) in excess collateral through unfair liquidation mechanics. The lawsuit coincides with BitMEX's announced full shutdown on September 23, 2026, raising concerns about legal uncertainty for users with outstanding funds.
