Two Major Crypto Exchanges to Shut Down: What's Behind It?

Two established crypto exchanges announced within three days of each other that they are closing for good, and neither official statement explains much. BitMEX and BitMart both point to strategic reviews of their business. Third-party analysis fills in the rest: BitMEX bled derivatives market share for years and could not find a buyer, while BitMart never fully shook off a 2021 hack and got squeezed as liquidity concentrated at the largest venues. Neither has disclosed insolvency, and both say withdrawals remain open.

The timing is the striking part. BitMEX (@BitMEX) posted its farewell on 23 July 2026. BitMart (@BitMartExchange) followed on 26 July. It is almost unheard of for two established centralized exchanges to exit in the same week, and coverage across the industry has treated the back-to-back announcements as a signal of how brutal the middle of the exchange market has become.

Why Is BitMEX Really Closing?

BitMEX told users it shares the news "with a very heavy heart": the exchange shuts down on 23 September 2026 at 04:00 UTC. The decision came from the board of HDR Global Trading Limited, the exchange's owner and operator, following a strategic review of the business. New account registrations stopped immediately. From 26 August at 04:00 UTC, accounts go reduce-only, meaning no new positions, and remaining open positions can be force-closed for an orderly wind-down. Users who leave assets behind after closure face a monthly fee of roughly $50 or 1% per year, whichever is greater. The farewell leaned on legacy: more than 11 years of operation, the invention of the 100x perpetual swap, and zero customer funds lost to hacks.

That is the official version. Analysis published by BeInCrypto points to three concrete problems behind it:

• Collapsed market share. BitMEX pioneered the perpetual swap that now dominates crypto trading, but the traders left long ago. By mid-2023 it ranked ninth among derivatives venues with roughly 0.9% of volume, per CoinGecko data, and its share kept shrinking as liquidity migrated to larger CEXs and decentralized derivatives platforms.
• A failed sale. The company retained Broadhaven Capital Partners in February 2025 to find a buyer. Seventeen months later, no deal had closed.
• A shrunken insurance fund. The fund peaked near 37,795 BTC in October 2021. It now holds about 3,694 BTC plus about $30.8 million in USDT, around 90% below its peak, and some analysts viewed it as a liability in any sale rather than an asset.

Regulatory history added weight. Co-founders Arthur Hayes (@CryptoHayes), Benjamin Delo, and Samuel Reed pleaded guilty in 2022 over the platform's failure to run a Bank Secrecy Act-compliant anti-money laundering program, according to CNBC, and US President Donald Trump pardoned them in 2025. A 2021 settlement with US regulators cost $100 million, and a further $100 million criminal fine landed in January 2025. That baggage raised costs and reportedly deterred potential acquirers. Senior executives, including the CEO and CFO, left the company in late June, weeks before the announcement, a departure wave widely noted in coverage.

What Is Happening at BitMart?

BitMart's notice cites an evaluation of its "operating conditions, market environment, and future strategic direction." The wind-down runs in phases:

• 26 July 2026, 01:30 UTC: new registrations, deposits, and new trading orders begin to be suspended; futures accounts switch to reduce-only.
• 26 August 2026, 01:00 UTC: all trading services end, including spot and futures; the platform may settle remaining positions itself.
• 31 January 2027, 15:59 UTC: platform operations officially cease, with limited login access afterward for records and withdrawal requests.

Withdrawals stay open throughout, though the notice warns some requests may face extra compliance and security reviews. Users are urged to close positions, complete KYC where needed, and withdraw early.

Then came the twist. Global CEO Nenter (Nathan) Chow (@50Nent) said on X that he was informed on 24 July that his employment was terminated and his offboarding began immediately. He said he played no role in management or decision-making after that date, was not consulted on the wind-down, and learned of it only when it became public. BMX, the exchange's token, fell nearly 60% in 24 hours, trading near $0.066 on Sunday.

The commercial backdrop mirrors BitMEX's, with a hack instead of a courtroom. In December 2021, attackers drained an estimated $150 million to $196 million from BitMart hot wallets. The exchange covered customer losses, but analysts say liquidity and confidence never fully recovered, and capital kept migrating to deeper venues. In May 2026, BitMart faced withdrawal complaints, which it attributed to risk controls on accounts accused of farming subsidies, and promised fuller proof-of-reserves that had not materialized by the shutdown notice. The reversal from its own messaging is sharp. BitMart secured an Australian Financial Services Licence in June, claimed more than 13 million users, and reported around 256% growth in assets under management in its first-half report. Chow had said the eight-year-old exchange planned "to be here for the next eight."

Are the Two Shutdowns Connected?

There is no evidence of coordination. Contemporaneous coverage treats the timing as coincidence, but coincidence with a message: both exits trace back to the same squeeze. The exchange business has consolidated hard, with the top three venues already handling about 78% of trades in 2023, a gap analysts say has only widened since. Perpetual swaps, once BitMEX's edge, now trade everywhere. Compliance costs keep climbing. Liquidity attracts liquidity, so traders go where the order books are deepest and market makers follow, leaving mid-tier venues caught between the giants above and decentralized platforms below.

Just as telling is what these closures are not. Neither looks like FTX. Both are structured wind-downs with withdrawal windows and no disclosed customer shortfall, exits on their own terms rather than collapses.

Questions remain open on both sides. Within a day of BitMEX's announcement, a proposed class action was filed alleging the platform was designed to force-liquidate customers and seize their Bitcoin. At BitMart, Chow's account leaves unanswered who actually made the call, and the community is watching on-chain outflows as withdrawals process under manual review. One date now binds both platforms: on 26 August 2026, BitMart halts all trading and BitMEX flips to reduce-only. Users still holding positions on either venue have a month to act.
