The King of Leverage Bows Out: BitMEX Is Dead, Perpetual Contracts Are Immortal

Author: Xiao Bing

On July 23, BitMEX published a farewell letter on its official website.

The exchange will cease trading services on September 23, 2026. No specific reason was given, only that the board decided to close the exchange after reviewing the company and the entire crypto 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 taken away a new generation of traders. Many users who just entered the industry do not even know BitMEX.

But its exit is still worth being seriously recorded.

Today, almost the most important product for all crypto exchanges, perpetual contracts, was productized and introduced to the entire industry by BitMEX. It also brought high leverage, funding rates, mark price, and auto-deleveraging into the crypto market, shaping the trading methods of the subsequent decade.

If stablecoins brought the U.S. dollar into the crypto world, then perpetual contracts represent another opposite route: a financial product that matured in the crypto market being accepted by traditional finance.

Exchanges will die, perpetual contracts will not. This is probably the most decent obituary BitMEX left for this industry.

Three People, One Hundred Times

In 2014, Arthur Hayes, a former trader at Deutsche Bank and Citibank, registered a company called BitMEX in Hong Kong, full name Bitcoin Mercantile Exchange. His partners were mathematician Ben Delo and programmer Samuel Reed.

Three people, one vision: to move Wall Street's derivatives gameplay onto Bitcoin, and to turn leverage up to levels Wall Street dared not imagine.

One hundred times.

In the world of traditional finance, the leverage retail investors can touch is usually two to five times, and futures professionals stretch it to twenty times at most. BitMEX directly gave one hundred times, meaning a 1% adverse price movement would zero out the position. Critics called it a "Bitcoin casino," but Hayes never argued. He wore T-shirts printed with "100x" in public, treating the casino's neon lights as brand assets.

The early crypto market provided the best soil for this radicalism. No regulation, no KYC, an email address was enough to open an account. Gamblers and traders from all over the world flocked to the same order book. By 2019, BitMEX's daily trading volume exceeded 16 billion U.S. dollars. It moved into the Cheung Kong Center in Hong Kong, renting the most expensive office in Asia at the time, right below Li Ka-shing.

In July of that year, Hayes debated with "Doctor Doom" Roubini in Taipei, and the venue was packed. A Wall Street outcast, relying on an offshore casino, sat in a position to argue with mainstream economists.

This was the peak of BitMEX, and also the peak of the old era crypto industry: savage, profitable, and only a time zone away from the iron fist of regulation.

One Contract, Rewriting Market Structure

Viewing BitMEX only as a casino would miss some key information.

In May 2016, BitMEX launched XBTUSD, the first perpetual contract in human financial history.

To understand its weight, one must first understand the trouble with traditional futures: futures have expiration dates, settling once every quarter. Traders have to constantly roll positions, and liquidity is chopped into contracts of different months, like a river segmented by dams.

Perpetual contracts removed all dams. They have no expiration date and can be held forever, anchored to the spot price by a mechanism called funding rate: if the contract price is higher than spot, longs pay shorts a small sum every eight hours; if lower than spot, vice versa. The further the price deviates, the higher the rate. Arbitrageurs smell the money and enter the market, pulling the price back to the anchor point.

No settlement, no rolling positions, a river flowing from start to end, all liquidity converging into the same pool.

The brilliance of this design lies in using a simple economic incentive to replace the entire complex settlement and clearing system of traditional futures.

Its profound impact can only be seen clearly in a larger coordinate system: stablecoins solved the "cash" problem in the crypto world, allowing U.S. dollars to circulate on-chain in token form; perpetual contracts solved the "risk transfer" problem, allowing anyone to express views on price in any direction at any time.

In over ten years of the crypto industry, original financial engineering truly exported back to traditional finance can be counted on one hand, and these two rank at the very front.

The adoption curve is the best evidence.

Perpetual contracts first swallowed the crypto derivatives market: Binance, OKX, and Bybit copied it entirely, FTX rose on it, Hyperliquid moved it on-chain. Nowadays, crypto derivatives trading volume crushes spot by several times, with perpetuals being the main force.

Then, traditional finance also began to look back and study this "invention of the offshore casino": U.S. regulators publicly discussed introducing perpetual contracts into regulated markets, and compliant exchanges queued up to apply for listing perpetual products.

In May 2026, the U.S. Commodity Futures Trading Commission (CFTC) officially approved the listing of Bitcoin perpetual contracts, with Kalshi and Coinbase receiving approval first.

The student became the teacher; tools invented by casinos are being repackaged into mainstream finance by people in suits.

312 and October 1st

In the script of rise and fall, BitMEX has two precise turning point dates.

On March 12, 2020, the global market crashed, and Bitcoin plummeted from nearly 8,000 U.S. dollars to 3,600 U.S. dollars. Long positions on BitMEX liquidated in a chain reaction, the liquidation engine poured sell orders into the thin order book, sell pressure ate through buy orders, and prices fell out of control.

In the deepest fear of the market, BitMEX announced a "hardware failure" and went offline for maintenance. During the downtime, prices on other exchanges stopped falling and rebounded.

FTX founder SBF later said that if BitMEX had not gone offline, the Bitcoin price might have gone to zero.

One accident made the whole market see clearly: this exchange's liquidation mechanism had become large enough to single-handedly decide the life and death of Bitcoin.

Also starting from 312, the window of opportunity for competitors began to open, with Binance, Bybit, and FTX continuously carving up its market share over the following year.

On October 1, 2020, a heavier hammer fell.

The U.S. Department of Justice and CFTC acted simultaneously, suing Hayes, Delo, Reed, and executive Dwyer for violating the Bank Secrecy Act. The core charge was knowingly allowing U.S. users to trade on the platform while refusing to establish an anti-money laundering and KYC system.

Reed was arrested in the U.S., Hayes fled to Singapore before returning to the U.S. to surrender. The three founders collectively exited management, pleading guilty one after another. Hayes was sentenced to probation plus home confinement, and Delo, once the youngest self-made billionaire in the UK, also pleaded guilty and received a sentence.

At the company level, BitMEX pleaded guilty and was fined an additional 100 million U.S. dollars by FinCEN in early 2025.

In March 2025, Trump pardoned the four individuals. The period in the legal sense was closed, but the death penalty in the business sense had been executed five years earlier.

After mandatory KYC, BitMEX lost its most primitive moat: anonymity and no barriers. Compliant, it could not compete with Binance's scale, Bybit's product iteration, let alone on-chain native Hyperliquid.

Market share shrunk from absolute dominance at its peak to a color block in statistical charts that needed zooming in to be seen.

A Long Farewell

In the last six years, BitMEX changed four CEOs.

After Hayes came Höptner, Höptner left during the 2022 bear market, and Lutz took over.

In early 2025, the company was exposed to be seeking an overall sale. A year and a half passed, and no buyer was willing to take over.

At the end of June 2026, three 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 relying on title changes on LinkedIn. The succeeding CEO Wilkinson was from a legal background. The market understood this signal at the time: a ship with a lawyer as captain usually heads for a shipbreaking yard. This time, it didn't even wait for a buyer at the shipbreaking yard.

Looking back, BitMEX's life is a complete specimen of the barbaric era of the crypto industry: a window period of regulatory arbitrage, a group of smart people who understood derivatives, an original product that rewrote market structure, enforcement that was late but inevitable, a share loss that no one could escape, and a curtain call with no one to take over.

After September 23, bitmex.com will become an empty domain. And on trading terminals around the world, funding rates will still settle every eight hours, longs paying shorts, or shorts paying longs, punctually like the tides.

The company that invented this tide has sunk, but the tide itself is still pushing the entire market forward.
