BitMEX will permanently shut down on September 23, 2026 at 04:00 UTC, with new account registrations already halted and trading ending on the shutdown date. The platform, a pioneer of perpetual swaps since 2016, helped reshape crypto derivatives but has faced intense competition and heightened regulatory pressure contributing to its decline. In the weeks leading up to the shutdown, BitMEX will progressively restrict activity: no new positions beginning August 26, followed by a wind-down that includes force-close steps to liquidate remaining exposure. After trading ends, users can still log in to withdraw funds, but those who leave assets on the platform may incur a monthly maintenance fee or annualized charges, with the possibility of fee increases later. The decision results from a strategic review of the business and the broader crypto industry, reflecting liquidity migration to rivals and a shift toward centralized and decentralized derivatives venues. BitMEX notes it remains solvent and emphasizes that users should act to withdraw assets before the deadline to avoid penalties.
