BitMEX will permanently shut down its exchange on Sept. 23, ending an 11-year run for the platform that introduced the 100x leverage perpetual swap.

The exchange had been looking for a buyer since February 2025, when it retained Broadhaven Capital Partners to run a sale process.

The board of HDR Global Trading Limited, the exchange's owner and operator, reached the decision after a strategic review of the business and the wider crypto industry, according to a Thursday announcement.

New account registrations stopped immediately.

Arthur Hayes co-founded BitMEX in 2014 with a stated mission of opening professional-grade crypto derivatives to retail traders.
