Crypto Exchange BitMEX Faces Class Action Lawsuit Over Manipulated Liquidations
On the same day that crypto derivatives platform BitMEX announced its closure in September, it was hit with a class action lawsuit by BKX Services and David Namdar.
The plaintiffs accuse the platform of manipulating forced liquidations through internal trading privileges and system design, resulting in a total loss of 622.66 BTC for users, and are seeking restitution and damages.
The lawsuit is event-driven, with funds and attention shifting to other derivatives exchanges, benefiting competitors with more transparent liquidation mechanisms, while BitMEX's remaining users and insurance fund are under pressure.

BitMEX, founded by Arthur Hayes and others, is known for its 100x leverage perpetual contracts and has faced multiple U.S. regulatory challenges and class action lawsuits since 2020. A similar liquidation-related lawsuit was voluntarily withdrawn in 2025.
In terms of capital flow, the platform profits from automatically liquidating remaining collateral into the insurance fund, while its internal trading team can continue operations during user server freezes, motivated by maximizing liquidation profits in a high-leverage market.
Similar cases can be seen with FTX and Celsius prior to their bankruptcies, currently transitioning from traditional high-leverage exchanges exiting to compliant platforms taking over liquidity.
This situation fundamentally reflects regulatory changes, where the mechanisms of high-leverage liquidation rules and information asymmetry allow the platform to systematically profit during extreme volatility, ultimately leading users to seek recourse through litigation.
