The crypto derivatives platform BitMEX faces a class action lawsuit for 622.66 bitcoins, filed on July 24, 2026, before the federal court in New York. The plaintiffs accuse the exchange of orchestrating fraudulent liquidations to seize their clients’ bitcoins. This legal action coincides with the very day BitMEX announces the end of eleven years of operation.
The case does not come out of nowhere. As early as 2020, a first class action led by Brett Messieh already pointed to similar practices at BitMEX, accusing the platform of manipulating its liquidation engine to the detriment of traders. This procedure was voluntarily dropped without prejudice on June 30, 2025, but suspicions never completely disappeared.

According to the court document, an internal trading desk had access to confidential client information and could continue operating during server freezes that prevented ordinary users from accessing or closing their positions.
BitMEX rejects these accusations. “BitMEX has already faced many similar complaints in its history and has successfully handled them all“, a spokesperson for the platform told Cointelegraph.
This is yet another opportunistic baseless complaint; we will vigorously defend ourselves once again.
The timing of this lawsuit coincides with the shocking announcement of BitMEX’s closure, scheduled for next September 23. A coincidence that the plaintiffs’ lawyers will surely exploit.
At the heart of the dispute is BitMEX’s liquidation mechanism. The platform allowed its clients to use leverage up to 100 times their collateral and then automatically liquidated positions. The problem, according to the plaintiffs, lies in what the exchange did with the remaining bitcoin after liquidation.
According to the complaint, positions were liquidated while the collateral was still worth about twice the losses incurred. The excess BTC was not returned to the traders but transferred to the platform’s insurance fund. A mechanism that, if proven, would turn every liquidation into a source of profit for the exchange.
BKX Services claims at least 305.81 BTC, while David Namdar demands more than 316.85 BTC. Both plaintiffs seek to represent all American clients who have bought derivative products on BitMEX since July 23, 2018. They request the return of the allegedly confiscated bitcoins, as well as compensatory and punitive damages.
The extreme leverage offered by BitMEX has long been its hallmark. But it also exposes the platform to recurring criticism about the transparency of its liquidation engine. The trial’s central question will be whether BitMEX abused this mechanism to enrich itself at the expense of its own clients.
The closure announcement is a seismic event for the crypto ecosystem. BitMEX has stopped accepting new registrations and will block the opening of new positions as of August 26. This decision, made after a strategic review by its parent company HDR Global Trading, caused the utility token BMEX to collapse, plunging about 90% shortly after.
The platform had already begun downsizing in July by removing 65 trading pairs and several derivative products from its offer. However, these warning signs had not foretold such a rapid total closure.
The irony of the timing is not lost on anyone: the day BitMEX announces its farewell, a New York court files a complaint that could cost the exchange dearly. BitMEX’s defense will have to convince the court that the contested liquidations were part of the normal market functioning and not a deliberate strategy for enrichment.
In sum, the fate of BitMEX illustrates the increasing pressure faced by traditional crypto platforms, caught between increasingly assertive regulators and clients who no longer hesitate to bring their grievances to court.
The drop of the BMEX token, the multiplication of class actions targeting exchanges, and the context of a sharp closure paint an unequivocal picture: the era of opaque platforms is coming to an end. The question remains whether the 623 bitcoins claimed will one day return to the wallets of their legitimate owners.
