Summary of Key Points
BitMEX, an exchange that once redefined the rules of crypto trading with its "100x leverage" and "perpetual contracts," has announced it will cease operations in September 2026. Its closure marks the end of an era of rapid growth in the crypto industry: from a "offshore casino" created by outsiders from Wall Street, to the invention of perpetual contracts that influenced traditional finance, to a company that lost its competitive edge due to regulatory pressures and was eventually overtaken by competitors. However, the perpetual contracts it introduced continue to drive the crypto market today.
I. BitMEX: The "Rule Breaker" of the Crypto World and Inventor of Perpetual Contracts
BitMEX's most significant contribution was the introduction of perpetual contracts to the market. Traditional futures have expiration dates, requiring traders to constantly rollover their positions, which divides liquidity into multiple segments. In contrast, perpetual contracts have no expiration date and are priced in relation to the spot price through a "fees structure." If the contract price is higher than the spot price, long holders pay fees to short holders; otherwise, short holders pay fees to long holders. This mechanism prevents prices from deviating too far from the spot price and ensures that all liquidity remains in one pool.
How important are perpetual contracts? Currently, the trading volume of crypto derivatives (such as contracts) is several times that of spot transactions, with perpetual contracts being the dominant type. Even traditional finance has begun to adopt them—The U.S. CFTC has approved the listing of Bitcoin perpetual contracts, and compliant exchanges are eager to offer them. It can be said that stablecoins brought the dollar into the crypto world, while perpetual contracts have had a reverse impact on Wall Street.
II. 100x Leverage + Lack of Regulation: BitMEX as a "Paradise for Gamblers"
BitMEX was founded by three individuals with backgrounds in Wall Street: former Deutsche Bank trader Arthur Hayes, mathematician Ben Delo, and programmer Samuel Reed. They offered aggressive leverage to retail investors—up to 100x, compared to a maximum of 5x in traditional finance and 20x for professional traders. This meant that even a 1% reversal in Bitcoin's price could result in the loss of all positions.
In the early days of the crypto market, there was little regulation, and no KYC (know-your-customer) requirements were necessary; investors from around the world flocked to BitMEX. At its peak in 2019, its daily trading volume exceeded $16 billion, and it rented the most expensive office in all of Asia in Hong Kong (right next to Li Ka-shing's property). Hayes even debated with renowned economist Nouriel Rubini, demonstrating how an offshore platform could compete on equal terms with mainstream economists—a testament to the wild growth and high profits of that era.
III. Turning Points: The 2020/312 Crash and Regulatory Stricts
BitMEX's decline was triggered by two major events:
1. The 2020/312 Crash: Bitcoin prices plummeted from $8,000 to $3,600, causing numerous long positions on BitMEX to become liquidated. The exchange's clearing system experienced technical failures, leading to a shutdown. While other exchanges recovered, SBF (the former owner of FTX) suggested that without the shutdown, Bitcoin prices might have dropped to zero. This incident highlighted BitMEX's vulnerability and exposed its risks, prompting competitors (such as Binance, Bybit, and FTX) to gain market share.
2. Regulatory Actions in October 2020: The U.S. Department of Justice and CFTC sued BitMEX's founders for failing to implement anti-money laundering and KYC requirements for American users. The founders were either arrested or surrendered, and the company was fined $100 million. After being forced to adopt KYC, BitMEX lost its key advantages of anonymity and accessibility, making it unable to compete with larger, more compliant exchanges.
IV. Why Close Now?
BitMEX's fate was largely predetermined:
- Lack of Competitive Advantages: After becoming compliant, it lacked the scale of Binance or the rapid product development of Bybit. Even decentralized platforms like Hyperliquid attracted new users.
- Management Instability: The company changed CEOs four times in six years and attempted to sell itself in 2025 without a buyer. In 2026, most of its management resigned (which was only discovered through LinkedIn). Hiring a CEO with legal experience signaled that BitMEX was preparing for its end.
V. The Legacy: The Exchange May Disappear, but Perpetual Contracts Live On
BitMEX's closure does not mark the end of its impact. Its perpetual contracts have become an essential part of the crypto industry infrastructure. The fees structure it introduced is still in use globally, with settlements occurring every eight hours, like a regular tide. Regardless of BitMEX's fate, this mechanism continues to drive market activity.
BitMEX's story encapsulates the wild growth of the crypto industry: it capitalized on regulatory loopholes and innovative products to dominate for a time but was ultimately defeated by regulation and competition. However, truly valuable innovations transcend their creators and become an integral part of the industry. Although BitMEX is closing, the legacy it left behind will continue to shape the crypto landscape.
In Summary: BitMEX was a pioneer in the crypto world, gaining fame for its boldness and innovation. Although it ultimately succumbed to regulation and changing times, its inventions have permanently changed the financial landscape.
