BitMEX is shutting down. The exchange has said it closes on 23 September 2026 at 04:00 UTC, after eleven years, and the wind-down is already under way.
Positions went reduce-only on 26 August 2026, so you can close positions but not open new ones. Anything still open when the exchange closes gets force-closed automatically. BitMEX has said you will still be able to log in afterwards to withdraw and view your history for a period, but it is urging people not to wait, and has warned that withdrawals may slow down as the date approaches.
There is also a cost to leaving money behind. BitMEX has said verified accounts still holding a balance will be charged a monthly fee, the greater of about 50 dollars or 1% a year of what is left.
What you get out of the box
Pick your import method.
Before access goes
- Withdraw your funds first. That is the part with a hard deadline and a fee attached.
- Then export everything: your trade and order history for every contract you traded, your realised profit and loss, your funding payments, and your deposits and withdrawals.
- Funding records matter more here than on most exchanges, because on perpetuals they are a running series of separate events rather than part of the trade.
- If your API key still works, connecting it now is the fastest way to pull the full history in one go.
On Kryptos
- Go to Kryptos.io and sign up with your Google account.
- From the menu, click Integrations.
- Click Add Integration and search for BitMEX.
- Upload the files you exported. If your API key still works, Import using API Keys pulls everything in one go instead.
- Check the imported totals against your own records before the exchange goes, while you can still look something up.
Good to know
- Positions have been reduce-only since 26 August 2026, so you can close but not open.
- Anything still open at closing time is force-closed for you, at whatever the price happens to be.
- Export before you close the account. Reconstructing a derivatives history after the venue has gone is close to impossible.
- Keep the raw files somewhere safe even after importing them. If a tax authority asks years later, the exchange will not be there to ask.
Why exporting now matters more than usual
When an exchange closes, the history closes with it. Support queues shorten, then stop. Login pages redirect. The records you assumed you could fetch next spring stop being fetchable.
That is awkward for spot trading and genuinely painful for derivatives. A year of perpetual trading is not a list of buys and sells; it is positions, funding running the whole time they were open, margin moving in and out, and liquidations. None of that can be rebuilt from a bank statement or a wallet address, because none of it happened on a blockchain.
So pull everything while you can, import it, and keep the original files. For how derivatives are treated where you file, see the USA crypto tax guide or the UK crypto tax guide.

Records that outlive the exchange
Once BitMEX goes, so does the ability to ask it anything. Importing your history now means your report survives the venue closing, which matters if a question arrives years later.
Funding kept apart from profit
A perpetual pays or charges funding continuously, separately from what you make or lose closing it. Rolled into one number they cannot be reported properly, and there is no going back to separate them.
A forced exit priced correctly
Positions still open at closing time are closed for you. That is a disposal on a date and at a price you did not choose, and it still needs to appear in the right tax year.
Audit-ready, automatically.
Once your wallets and exchanges are connected, generating a tax report takes a single click. Open Reports from the menu, choose your jurisdiction, and download.
A force-close is still a disposal
Positions closed for you at the shutdown are disposals like any other, at whatever price they closed. You did not choose the date, but it is the date that counts.
Funding is between traders, not a fee
On perpetuals, funding passes between the long and short sides rather than being charged by the exchange. Recorded as a fee it understates your income when you were receiving it.
Derivatives are not ordinary trades
Most countries tax futures and perpetuals under different rules from buying and selling an asset. A history flattened into trades is wrong in a way that is hard to spot later.
Moving your funds out is not a sale
Withdrawing to your own wallet or another exchange is a transfer between your own accounts, not a disposal. It only reads that way if the receiving side is missing, so add the destination too.
Read-only by design.
- Create the key with read permission only, never withdrawal
- A read-only key can see your history but can't move funds
- Kryptos never asks for your password or login details
- Revoke the key on the exchange at any time and the connection stops
If something doesn't sync.
Access changes as the wind-down progresses. Use the export files instead, and keep the raw downloads rather than relying on being able to come back for them.
Anything left open at the shutdown is force-closed automatically. It is a real disposal and belongs in your report.
Funding exports separately from trades on most derivatives venues. Pull it as its own file before access ends.
