杠杆之王谢幕：BitMEX死了，永续合约永生

Original Author: Xiaobing

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 stating that the board of directors decided to close the exchange after reviewing the company and the broader crypto industry.

In today's crypto market, BitMEX is no longer considered a mainstream exchange. Binance, OKX, and Bybit dominate the centralized derivatives market, while on-chain platforms like Hyperliquid have attracted a new generation of traders. Many users new to the industry don't even know about BitMEX.

Yet its exit is still worthy of a serious record.

The most important product of virtually all crypto exchanges today—the perpetual contract—was productized and introduced to the entire industry by BitMEX. It also brought high leverage, funding rates, mark prices, and auto-deleveraging into the crypto market, shaping the way trading has been conducted for the past decade.

If stablecoins brought the US dollar into the crypto world, then perpetual contracts represent the opposite trajectory: a financial product matured within the crypto market, now being embraced by traditional finance.

Exchanges may die, but perpetual contracts will not. This is perhaps the most dignified epitaph BitMEX leaves for this industry.

Three People, One Hundred Times Leverage

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

Three people, one vision: Bring Wall Street's derivatives playbook to Bitcoin, with leverage levels Wall Street wouldn't dare to imagine.

One hundred times.

In the traditional financial world, retail investors typically have access to leverage of 2x to 5x, with professional futures traders maxing out at 20x. BitMEX offered 100x directly, meaning a 1% adverse price move would liquidate a position. Critics called it a "Bitcoin casino." Hayes never defended it; he wore T-shirts emblazoned with "100x" in public, turning the casino's neon lights into a brand asset.

The early crypto market provided the perfect soil for such aggression. No regulation, no KYC, just an email address to open an account, funneling gamblers and traders from around the world into a single order book. By 2019, BitMEX’s daily trading volume exceeded $16 billion. It moved into Hong Kong's Cheung Kong Center, leasing what was then Asia's most expensive office space, with Li Ka-shing's headquarters just downstairs.

In July of that year, Hayes debated "Dr. Doom" Nouriel Roubini on stage in Taipei to a packed house. A Wall Street outcast, thanks to an offshore casino, found himself in a shouting match with a mainstream economist.

This was BitMEX's zenith, and also the zenith of the old-school crypto industry: Wild, hyper-profitable, and just one time zone away from the regulatory hammer.

One Contract, Reshaping Market Structure

Viewing BitMEX only as a casino misses a crucial point.

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

To understand its significance, one must first grasp the headache of traditional futures: they have expiration dates, requiring quarterly settlement. Traders must constantly roll over positions, fragmenting liquidity across different contract months like a river dammed into multiple sections.

Perpetual contracts removed all the dams. They have no expiration date and can be held indefinitely. A mechanism called the funding rate anchors the contract price to the spot price: if the contract price is higher than the spot, longs pay a small fee to shorts every eight hours; if lower, the reverse happens. The further the price deviates, the higher the rate, attracting arbitrageurs who smell profit and pull the price back to the anchor.

No expiration, no rolling over. One river flows uninterrupted from start to end, channeling all liquidity into a single pool.

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

Its profound impact is best understood within a larger framework: stablecoins solved the "cash" problem in the crypto world, allowing the US dollar to circulate on-chain in token form; perpetual contracts solved the "risk transfer" problem, allowing anyone to express a view on price direction at any time.

In over a decade of the crypto industry, the original financial engineering successfully exported back to traditional finance can be counted on one hand. These two innovations are at the top of that list.

The adoption curve is the best evidence.

Perpetual contracts first consumed the crypto derivatives market: Binance, OKX, and Bybit copied them entirely, FTX rose on their back, and Hyperliquid moved them on-chain. Today, crypto derivatives trading volume dwarfs spot by multiples, almost entirely driven by perpetuals.

Then, traditional finance began to look back and study this "invention from an offshore casino": US regulators publicly discussed introducing perpetual contracts into regulated markets, and compliant exchanges lined up to launch perpetual products.

In May 2026, the US Commodity Futures Trading Commission (CFTC) formally approved the listing of Bitcoin perpetual contracts, with Kalshi and Coinbase being the first to receive approval.

The student became the teacher. A tool invented in a casino is being repackaged by people in suits and brought into mainstream finance.

March 12 and October 1

In the story of hitting a peak followed by decline, BitMEX's turning points are marked by two precise dates.

On March 12, 2020, global markets crashed. Bitcoin plummeted from nearly $8,000 to $3,600. Long positions on BitMEX were liquidated in a cascade, with the liquidation engine flooding the thin order book with sell orders. Selling pressure overwhelmed buy support, and the price spiraled down uncontrollably.

In the deepest fear of the market, BitMEX announced a "hardware malfunction" and halted maintenance. During the shutdown, prices on other exchanges stabilized and recovered.

FTX founder SBF later said that if BitMEX hadn't stopped trading, the Bitcoin price might have gone to zero.

This single incident made the entire market realize: BitMEX's liquidation mechanism had grown so large that it could single-handedly determine Bitcoin's fate.

Starting from 3/12, the window of opportunity for competitors began to open. Binance, Bybit, and FTX steadily chipped away at its market share over the following year.

On October 1, 2020, a heavier hammer fell.

The US Department of Justice and the CFTC simultaneously took action, suing Hayes, Delo, Reed, and executive Dwyer for violating the Bank Secrecy Act. The core charge was knowing US users were trading on the platform but refusing to establish anti-money laundering and KYC systems.

Reed was arrested in the US. Hayes fled to Singapore before returning to the US to surrender. All three founders collectively stepped down from management and pleaded guilty. Hayes received probation and home confinement. Delo, once Britain's youngest self-made billionaire, also pleaded guilty and received a sentence.

At the corporate level, BitMEX pleaded guilty and was fined an additional $100 million by FinCEN in early 2025.

In March 2025, President Trump pardoned the four individuals. The legal chapter closed, but the commercial death sentence had already been executed five years prior.

After being forced to implement KYC, BitMEX lost its moat: anonymity and barrier-free access. Compliant, it couldn't compete with Binance's scale, Bybit's product iteration, or even the natively on-chain Hyperliquid.

Its market share shrank from absolute dominance to a sliver on the chart, barely visible without zooming in.

A Long Farewell

Over the final six years, BitMEX went through four CEOs.

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

In early 2025, the company was rumored to be seeking a full sale. A year and a half passed without a buyer willing to take over.

At the end of June 2026, three senior executives—CEO Lutz, CFO Steiner, and Growth Officer Polansky—departed on the same day. Without an official announcement, the outside world pieced the news together only from LinkedIn title changes. The incoming CEO, Wilkinson, had a legal background. At the time, the market clearly read the signal: hiring a lawyer to captain a ship usually means its destination is a scrapyard. And this time, not even a scrapyard buyer showed up.

Looking back, BitMEX's lifecycle is a complete specimen of the crypto industry's wild west era: a window of regulatory arbitrage, a group of smart people who understood derivatives, a groundbreaking original product that reshaped market structure, a belated but inevitable enforcement action, an unavoidable loss of market share, and a final curtain call without a buyer.

After September 23, bitmex.com will become an empty domain name. But on trading terminals worldwide, the funding rate will still settle every eight hours—longs paying shorts, or shorts paying longs—as reliably as the tides.

The company that invented this tide has sunk, but the tide itself continues to push the entire market forward.
