On July 23, BitMEX published a farewell letter on its official website.
This exchange will stop trading services on September 23, 2026, without providing a more specific reason, only stating that the board decided to shut down the exchange after reviewing the company and the entire cryptocurrency industry.
In today's crypto market, BitMEX is no longer considered a mainstream exchange. Binance, OKX, and Bybit dominate the centralized contract market, while on-chain platforms like Hyperliquid have attracted a new generation of traders. Many users who have just entered the industry may not even know BitMEX.
However, its exit is still worth noting seriously.
Today, the most important product of almost all crypto exchanges, perpetual contracts, was developed by BitMEX and introduced to the entire industry. It also brought high leverage, funding rates, mark prices, and automatic liquidations into the crypto market, shaping the trading methods for the next decade.
If stablecoins brought the US dollar into the crypto world, then perpetual contracts represent another opposite route: a financial product that matured in the crypto market and was accepted by traditional finance.
Exchanges may die, but perpetual contracts will not; this is probably the most dignified eulogy BitMEX leaves to this industry.
Three People, One Hundred Times
In 2014, former Deutsche Bank and Citigroup trader Arthur Hayes registered a company called BitMEX in Hong Kong, which stands for Bitcoin Mercantile Exchange. His partners were mathematician Ben Delo and programmer Samuel Reed.
Three people, one vision: to bring Wall Street’s derivatives gameplay to Bitcoin and crank up leverage to levels unimaginable on Wall Street.
One hundred times.
In the world of traditional finance, retail investors typically encounter leverage of two to five times, while futures professionals rarely exceed twenty times. BitMEX directly offered one hundred times, meaning that a 1% reverse price movement would wipe out the position. Critics called it the “Bitcoin casino,” and Hayes never defended it; he publicly wore a T-shirt emblazoned with “100x” and embraced the casino's neon lights as brand assets.
The early crypto market provided the best soil for such radical approaches. There was no regulation, no KYC; one email was enough to open an account, and gamblers and traders from around the world poured into the same order book. By 2019, BitMEX’s daily trading volume exceeded $16 billion, moving into the Cheung Kong Center in Hong Kong, renting the most expensive office in Asia at that time, right downstairs from Li Ka-shing.
In July of that year, Hayes debated “Dr. Doom” Nouriel Roubini in Taipei, with a full house. A Wall Street dropout, relying on an offshore casino, reached a level where he could spar with mainstream economists.
This was the peak of BitMEX and the peak of the old-era crypto industry: barbaric, lucrative, only a time zone away from the iron fist of regulation.
One Contract, Reshaping Market Structure
Viewing BitMEX solely as a casino misses some key information.
In May 2016, BitMEX launched XBTUSD, the first perpetual contract in human financial history.
To understand its significance, one must first grasp the troubles of traditional futures: futures have expiration dates, delivered once every quarter, forcing traders to constantly roll over contracts, with liquidity fragmented across contracts of different months, like a river split into segments by a dam.
Perpetual contracts removed all the dams. They have no expiration date and can be held indefinitely, anchoring spot prices with a mechanism called the funding rate: when the contract price is higher than the spot price, longs pay a small fee to shorts every eight hours; when it is lower, the opposite occurs. The further the price deviates, the higher the rate, enticing arbitrageurs to enter and pull the price back to the anchor point.
No need for delivery or rollovers, one river flows from start to end, with all liquidity converging into the same pool.
The brilliance of this design lies in its use of a simple economic incentive to replace the entire complex delivery and clearing system of traditional futures.
Its far-reaching impact can be seen more clearly in a broader context: stablecoins solved the “cash” problem in the crypto world, allowing dollars to circulate on-chain in token form; perpetual contracts addressed the “risk transfer” problem, enabling anyone to express their views on price at any time in any direction.
In over a decade of the crypto industry, the truly original financial engineering that has been exported back to traditional finance can be counted on one hand, and these two stand at the forefront.
The adoption curve is the best evidence.
Perpetual contracts first dominated the crypto derivatives market: Binance, OKX, and Bybit completely replicated them, FTX rose on their back, and Hyperliquid brought them on-chain. Today, trading volume in crypto derivatives surpasses spot trading by several multiples, with perpetual contracts being the main players.
Then, traditional finance also began to study this “offshore casino invention”: US regulators openly discussed introducing perpetual contracts into regulated markets, and compliant exchanges lined up to apply for perpetual products.
In May 2026, the US Commodity Futures Trading Commission (CFTC) officially approved the listing of Bitcoin perpetual contracts, with Kalshi and Coinbase being the first to receive approval.
Students became teachers, and tools invented by casinos are being repackaged back into mainstream finance by people in suits.
312 and October 1
In the script of rise and fall, BitMEX had two precise dates for its turning points.
On March 12, 2020, global markets crashed, and Bitcoin plunged from nearly $8,000 to $3,600. The longs on BitMEX faced a chain liquidation, and the clearing engine poured sell orders onto a thin order book, overwhelming the buy side, causing prices to plummet uncontrollably.
In the midst of the deepest fear in the market, BitMEX announced a “hardware failure” and went into maintenance. During the downtime, prices on other exchanges stopped falling and began to rise.
FTX founder SBF later said that if BitMEX had not gone offline, Bitcoin’s price might have gone to zero.
One incident showed the entire market clearly: this exchange’s clearing mechanism had become so significant that it could independently determine the life and death of Bitcoin.
Also starting from March 12, the window of opportunity for competitors began to open, with Binance, Bybit, and FTX continually siphoning off its market share in the following year.
On October 1, 2020, an even heavier blow fell.
The US Department of Justice and CFTC struck simultaneously, suing Hayes, Delo, Reed, and executive Dwyer for violating the Bank Secrecy Act, with the core accusation being that they knowingly allowed US users to trade on the platform while refusing to establish anti-money laundering and KYC systems.
Reed was arrested in the US, while Hayes fled to Singapore and later turned himself in. The three founders collectively withdrew from management, pleading guilty one after another. Hayes was sentenced to probation and home confinement, with Delo, once the youngest self-made billionaire in the UK, also pleading guilty and serving time.
At the corporate level, BitMEX pleaded guilty and was imposed an additional $100 million fine by FinCEN in early 2025.
In March 2025, Trump pardoned the four, legally closing the chapter, but the death sentence in commercial terms had already been executed five years prior.
After mandated KYC, BitMEX lost its oldest moat: anonymity and no entry barriers. Compliant, it couldn't compete with Binance's scale, Bybit's product iterations, or even the on-chain native Hyperliquid.
Market share shrank from absolute dominance at its peak to a section in statistical charts that requires magnification to see.
A Prolonged Farewell
In the last six years, BitMEX changed CEOs four times.
After Hayes came Höptner, who left during the bear market in 2022, and was succeeded by Lutz.
By early 2025, the company was reported to be seeking a full sale, but after a year and a half, no buyers were willing to take over.
At the end of June 2026, executives Lutz, CFO Steiner, and growth officer Polansky left on the same day, without even an official announcement; the outside world pieced together the truth only through LinkedIn title changes. The new CEO, Wilkinson, came from a legal background, and the market understood this signal: a ship led by a lawyer usually has its destination at the dock dismantling factory, and this time, not even the factory awaited a buyer.
Looking back, BitMEX's life is a complete specimen of the wild era of the crypto industry: a regulatory arbitrage window, a group of smart people who understood derivatives, an original product that reshaped market structure, a delayed but inevitable enforcement action, a period of share loss that no one could escape, and a curtain call with no one willing to take over.
After September 23, bitmex.com will become an empty domain name. However, on trading terminals around the world, funding rates will still be settled every eight hours, with longs paying shorts, or vice versa, like tides occurring on time.
The company that invented this tide has sunk, yet the tide itself continues to push the entire market forward.
