BitMEX has closed after 11 years, ending the exchange that invented the perpetual swap

What happened

BitMEX announced on 23 July 2026 that the exchange would cease operations at 04:00 UTC on 23 September 2026. It did. The home page at www.bitmex.com now reads "BitMEX has closed." and states that "Trading ceased on 23 September 2026 at 04:00 UTC" and that "All exchange services have ended", while users can still log in and withdraw. Its owner and operator, HDR Global Trading Limited, said the decision followed a strategic review of the business and the broader crypto industry. The wind-down ran to the schedule the July notice published. New account registrations stopped with immediate effect on 23 July. From 04:00 UTC on 26 August risk limits stopped users opening positions, leaving them able only to reduce, and BitMEX said it would force close existing positions "to ensure an orderly wind down of the market", with anything still open at the closure time closed immediately. Staked BMEX tokens were unstaked and returned to holder accounts. Verified users who have not withdrawn are "charged an account fee of 1% per annum (charged monthly), or USD 50 equivalent for accounts with no more than this amount, until fully withdrawn", a fee the notice says may rise on advance notice. The exchange says its proof of reserves shows platform liabilities fully covered by customer assets and points to a record without a platform hack across its 11 years.

Why it matters

BitMEX introduced the 100x perpetual swap, the contract design that came to dominate crypto derivatives trading across every major venue, centralised and onchain. Its closure is the clearest marker yet of consolidation among centralised derivatives exchanges as liquidity has concentrated on larger rivals and migrated to onchain venues.

What is not settled

The company attributes the closure to a strategic review and gives no competitive reason; the framing of lost market share comes from press reporting rather than from the announcement, and no volume or market-share figure appears on any page BitMEX controls. The treatment of the brand, of the BMEX token beyond unstaking, and of any remaining business lines is not stated, and neither is how long withdrawals will stay open. The account fee has been misreported in both directions, including here. This cluster previously said the treatment of balances left behind was described in coverage as monthly maintenance fees or an annualised levy; the closure notice has stated it plainly since 23 July, at 1% per annum charged monthly, or USD 50 equivalent for accounts holding no more than that. CoinDesk's account on the day of closure reads it as "a monthly fee based on an annualized 1% of assets or a $50 minimum, whichever is greater", which is a third reading and not what the page says.
