BitMEX Faces $491M Celsius Lawsuit Over ‘Black Thursday’ Liquidations Amidst Exchange Closure

In a dramatic turn of events as it winds down over a decade of pioneering crypto trading, derivatives exchange BitMEX finds itself embroiled in a high-stakes legal battle. The asset managers for the bankrupt crypto lending platform, Celsius Network, have initiated legal proceedings in a U.S. court. They seek to reclaim approximately 6,360 Bitcoin (BTC), an amount currently valued at nearly $491 million, which was liquidated during the infamous “Black Thursday” market crash in March 2020.

Court documents from the U.S. Bankruptcy Court for the Southern District of New York reveal that Celsius-related entities, acting through the Blockchain Recovery Investment Consortium (BRIC), filed the lawsuit on September 12. The suit targets five entities associated with BitMEX: HDR Global Trading, ABS Global Trading, 100x Holdings, Shine Effort, and HDR Global Services.

Notably, this legal challenge emerged just 11 days before BitMEX’s official cessation of all trading services, slated for September 23 at 04:00 UTC. BitMEX had previously announced its strategic decision to exit the exchange business in July and had even begun prematurely delisting and settling major perpetual and futures contracts, including XBTUSD and ETHUSD, on September 16.

Celsius Alleges Over 6,360 BTC Lost in Two-Phase Liquidation

The core of Celsius’s complaint centers on two distinct liquidation events during the tumultuous market period of March 2020. On March 12, a leveraged position held by Celsius was allegedly force-liquidated by BitMEX, resulting in a loss of approximately 1,325.84 BTC. The following day, an additional 5,034.33 BTC belonging to the investment fund JST was reportedly liquidated. JST subsequently transferred its claims to Celsius’s bankruptcy estate, bringing the total contested amount to 6,360.1666 BTC. [IMAGE-PLACEHOLDER-1]

Based on CoinMarketCap data, which priced Bitcoin at approximately $77,195 on September 18, this substantial sum of BTC now commands a market value approaching half a billion dollars.

The Heart of the Dispute: BitMEX’s Liquidation Engine Under Scrutiny

This lawsuit transcends a typical “margin call” dispute. Celsius’s allegations strike at the very heart of BitMEX’s liquidation mechanism during the extreme volatility of March 2020. [IMAGE-PLACEHOLDER-2]

The complaint asserts a significant conflict of interest, claiming BitMEX simultaneously controlled the price triggers for liquidations, the engine executing these liquidations, and the insurance fund that ultimately received a portion of the liquidated assets. Celsius further alleges that some liquidation sell orders were executed at prices more than 24% below the platform’s next best bid, arguing that this surge of automated liquidations created undue selling pressure, artificially depressing Bitcoin’s price.

Historical data from March 12-13, 2020, indeed shows Bitcoin plummeting from around $7,300 to approximately $3,900. The U.S. Commodity Futures Trading Commission (CFTC), citing data from Coin Metrics and Skew, previously noted that an estimated $1.1 billion in BitMEX contracts were liquidated during this period. Market analysts at the time identified the sell pressure from these automated liquidations as a contributing factor to the sharp decline.

Adding another layer of controversy, BitMEX experienced a reported DDoS attack at 02:16 UTC on March 13, leading to trading disruptions. While BitMEX acknowledged the incident delayed or blocked some user requests, attributing the downtime to the DDoS attack, Celsius now presents this interruption as crucial evidence. They contend that once the liquidation engine temporarily ceased operations, market selling pressure rapidly subsided, suggesting that BitMEX’s automated system may have significantly amplified the market downturn.

It is crucial to note, however, that these remain allegations put forth by Celsius in their lawsuit and have not yet been substantiated or recognized as facts by the court. The questions of whether BitMEX engaged in market manipulation, unlawful liquidation practices, or improper appropriation of client assets will be determined through subsequent judicial proceedings.

Final Legal Battle for BitMEX: A New Hope for Celsius Creditors

BitMEX has clarified that its decision to close the exchange was not driven by financial distress, cyberattacks, or immediate regulatory pressures, but rather a strategic board review to exit the market. With trading slated to cease on September 23, any remaining open positions will be forcibly settled by the system.

For the multitude of Celsius creditors, this lawsuit could represent a significant new avenue for asset recovery. If the court ultimately rules in favor of Celsius, the claim would not be based on the modest value of BTC at the time of liquidation in 2020 (when it was worth only a few thousand dollars per coin). Instead, it demands the return of the Bitcoin itself, or compensation calculated at its current, substantially higher market value.

This dramatic development transforms a six-year-old leveraged liquidation dispute from a historical market incident into a near half-billion-dollar bankruptcy recovery case, largely fueled by Bitcoin’s meteoric price appreciation since 2020.
