A proposed US class action lawsuit has been filed against BitMEX in the US District Court for the Southern District of New York, alleging the cryptocurrency derivatives exchange engineered customer liquidations to retain Bitcoin before its planned September shutdown. According to court filings, BKX Services Inc. and trader David Namdar filed the complaint on July 23, alleging they lost a combined 622.66 BTC through forced liquidations on BitMEX. BKX claims losses of at least 305.81 BTC, while Namdar alleges losses exceeding 316.85 BTC. The plaintiffs argue that BitMEX offered leveraged trading of up to 100 times customers' collateral but allegedly liquidated positions before all available collateral had been exhausted, with customers often losing their positions while remaining Bitcoin collateral was still worth substantially more than trading losses. The lawsuit seeks the return of the allegedly withheld Bitcoin along with compensatory and punitive damages, representing US customers who traded Bitcoin perpetual swap products dating back to July 23, 2018. The complaint alleges that BitMEX and co-founders Arthur Hayes, Ben Delo and Samuel Reed designed a system to retain customers' collateral and transfer the remaining Bitcoin to the platform's insurance fund, while an internal trading desk had access to private customer information and could continue trading during server freezes that prevented other users from closing their positions.
According to latest reports, BitMEX is removing 65 trading pairs and derivatives in July 2026 as the crypto exchange prepares for its final closure on September 23, 2026 at 04:00 UTC. The July delistings include 21 derivatives removed on July 2, nine spot pairs on July 16, and 35 derivatives scheduled for early settlement on July 30. The exchange attributed the first two July rounds to "insufficient trading interest," with the July 2 batch including contracts tied to Apple, Amazon, Avalanche, BMEX, Meta and Near Protocol. The final July round will remove crypto, foreign exchange, commodities and equity-linked products, including AAVEUSDT, COINUSDT, GOOGLUSDT, MSTRUSDT, NVDAUSDT, TSLAUSDT and WTIUSDT. This represents a sharp increase from the first half of 2026, when BitMEX removed only 19 contracts across January-June compared to the current 65 removals.
The closure represents a dramatic fall from BitMEX's former dominance in the cryptocurrency derivatives market. According to CoinGecko data, BitMEX ranked 9th by August 2023, holding just 0.9% of derivatives trades, while Binance captured 47.4% of the market. The decline has accelerated significantly, with market tracker Kaiko now placing BitMEX's share below 0.01% as of the latest data. Daily trading volume has dropped to approximately $400,000, representing a substantial decline from the exchange's peak position. The market shift occurred as traders migrated to larger venues, with the exchange's invention of the perpetual swap being copied by virtually every competitor. As reported by Reuters, this market share erosion made the exchange increasingly difficult to sell to potential buyers, despite its former leadership position in the leveraged crypto trading sector.
The most significant factor driving BitMEX's closure decision is its massive $270 million insurance fund, which has become a liability rather than an asset. According to on-chain data analysis, the fund peaked near 37,795 Bitcoin (BTC) in October 2021 but now holds approximately 3,694 BTC, representing a 90% decline from its peak. The fund also contains roughly $30.8 million in Tether (USDT). BitMEX deliberately reduced the fund in November 2025 but still maintained far more coverage than competitors, with its cushion covering 0.88 times open bets compared to Binance's 0.11 times. During the October 10, 2021 crash when traders lost $19.35 billion, BitMEX experienced only $38.5 million in losses with the fund giving up only about $2 million. However, analysts argue this massive fund made the exchange too difficult to sell, with crypto researcher Hasu noting that "it started as the golden goose, and then became the noose." The fund's existence raises questions about its future disposition after the September closure, with neither BitMEX nor founder Arthur Hayes having announced its destination.
As reported by BitMEX, the exchange has implemented a phased wind-down process beginning August 26, 2026. From this date, the platform will block new positions and allow only reductions of existing positions. The exchange will then force close open trades to settle the market in order, with any positions left open at closure getting closed automatically. During the following weeks, BitMEX will progressively force close outstanding positions to ensure what it described as an orderly shutdown of its markets. The company has also indicated that contracts with limited liquidity will undergo early settlement using its existing settlement procedures, with advance notice provided to affected users. This structured approach aims to ensure a smooth transition for all users, with the wind-down ending an 11-year run for the Seychelles-incorporated venue that debuted in 2014. Trading will continue until 04:00 UTC on July 30, after which the exchange will stop new funding calculations, cancel open orders and settle positions at stated prices without charging settlement fees.
The exchange's closure has triggered a dramatic collapse in its native token BMEX, which crashed nearly 90% in one day following the shutdown announcement. According to latest data, BMEX now trades near $0.0068, with its entire supply worth just $680,000. The token, launched by BitMEX in 2022, offered staking benefits including lower trading fees and other perks that became worthless once the exchange confirmed its closure. BMEX now trades about 98% below its price a year ago, hitting a record low near $0.0033 on Thursday before bouncing back slightly. The lawsuit also points to an earlier class action brought in 2020 by Brett Messieh and other traders, who made similar allegations under the Commodity Exchange Act, with that case being voluntarily dismissed without prejudice on June 30, 2025, allowing similar claims to be brought again. The exchange's closure follows a strategic review by HDR Global Trading and a wider management shake-up, with BitMEX losing its CEO, chief financial officer and head of growth last month, with general counsel Peter Wilkinson taking over as CEO. The closure serves as a warning to other exchanges, particularly those offering high leverage with limited spare cash and carrying legal baggage, as the market continues to consolidate around regulated rivals.
