What happened.

HDR Global Trading plans to wind BitMEX down by 04:00 UTC on Sept. 23, ending an 11-year run for the exchange described in the source record as having invented perpetuals. The record says new sign-ups will halt and users are being urged to withdraw.

The supplied record also says the BMEX token fell by about 90%. It frames the closure as part of a shift toward licensed venues, though it does not provide underlying market data or detail on the reasons for the decision.

Why it matters.

The exit removes an established derivatives venue and could concentrate open interest on a smaller set of exchanges. The practical market question is where BitMEX liquidity and funding move, and whether that migration changes conditions across remaining venues.

For current users, the record identifies an operational deadline: reduce-only trading is expected to start Aug. 26, with possible forced closes. Users with active positions or balances should review BitMEX’s own wind-down notices and withdrawal process rather than relying on this brief.

What to watch next.

The clearest receipt will be the exchange’s formal wind-down updates, including confirmation of trading restrictions, withdrawal access, and any handling of open positions. Market participants can also watch whether liquidity and funding visibly migrate to a few licensed exchanges.

What to watch

Watch BitMEX’s official wind-down notices, then observe where open interest, liquidity, and funding migrate after reduce-only trading begins.
