BitMEX Crypto Exchange Announces September 23 Shutdown

BitMEX, the Seychelles-based crypto exchange founded by Arthur Hayes, announced on July 23 that it will shut down at 04:00 UTC on Sept. 23. Customers now have two months to close positions and withdraw funds, and new registrations have already stopped.

The effective trading deadline arrives sooner. Under BitMEX's wind-down timetable, risk limits take effect at 04:00 UTC on Aug. 26, after which users will only be able to reduce positions.

BitMEX may force-close contracts during the wind-down and will immediately close anything still open at the Sept. 23 cutoff. The notice describes no position-transfer mechanism, so any exposure opened elsewhere would be a separate trade.

Customers who miss the closure time will still be able to log in to view balances and records and request withdrawals. However, KYC-verified accounts retaining assets will face a fee charged monthly at the greater of $50 equivalent or 1% per year on the remaining balance.

BitMEX also warned that additional reviews and blockchain constraints could delay withdrawals and said there is no priority service for moving funds.

Where BitMEX flow may move

No public data currently tracks where BitMEX customers are moving, so possible destinations can only be inferred from existing market scale, depth and product availability. A same-day CoinGecko snapshot showed about $120.84 million in 24-hour BitMEX volume and $705.33 million in open interest. Binance Futures showed $45.68 billion in 24-hour volume and $25.10 billion in open interest on the same provider.

There is no public trail showing where BitMEX customers are heading. Market size, liquidity and product choice offer the best clues. A same-day CoinGecko snapshot put BitMEX at $120.84 million in 24-hour volume and $705.33 million in open interest, compared with $45.68 billion and $25.10 billion, respectively, for Binance Futures.

The gap makes Binance the most obvious destination by scale. TokenInsight's Q2 report put Binance, OKX, Bybit and MEXC at a combined 72.46% of its covered derivatives market.

CoinGlass also ranks Binance first in derivatives volume, average open interest and BTC futures depth, with OKX, Bybit, Gate and Bitget forming the rest of its centralized top-five competitive set. Eligibility, collateral and matching contracts will shape each trader's choice.

Hyperliquid is also a plausible onchain option for eligible users. CryptoSlate reported in June that the venue had $240.5 billion in 30-day perpetual volume and $8.6 billion in open interest. The available data points to dispersion across already-deep pools rather than one new home.

That would marginally reinforce concentration, but BitMEX's 24-hour turnover is only about 0.26% of Binance's, limiting the likely market-wide volume displacement even as the deadlines remain absolute for customers.
