BitMEX, the crypto derivatives exchange co-founded by Arthur Hayes, is scheduled to shut down permanently on September 23, 2026. Multiple reports say the decision follows a move by the exchange’s owner, HDR Global Trading Limited, which determines to close the platform after conducting a strategic review. Cointelegraph and The Block both report the planned end date and link the shutdown to the owner’s decision to wind down operations, rather than any specific operational incident. The Block specifies the closure time as 04:00 UTC. After the shutdown, BitMEX will stop operating as a crypto derivatives venue. The reports do not provide additional details about customer impacts, whether trading and withdrawals will continue until the cutoff, or how positions will be handled in the lead-up to the closure. The announcement therefore centers on the permanent shutdown timeline and the ownership decision to end the exchange after more than a decade in operation.
