Setting the Remaining Contracts on the BitMEX Platform to Reduce Only from 7th September, and Delisting on 16th September

On 7 September 2026 at 04:00 UTC, BitMEX will set all remaining Futures contracts to Reduce Only mode. This impacts ETHUSDU26, XBTU26, XBTZ26 and XBTH27. On 8 September 2026 at 04:00 UTC, BitMEX will set ETHUSD and ETHUSDT to Reduce Only mode. 

On 10 September 2026 at 04:00 UTC, BitMEX will set XBTUSD and XBTUSDT to Reduce Only mode. 

When Reduce Only mode is set, traders are no longer able to increase the size of their positions, open positions can only be reduced and no new positions cannot be opened.

There is an exception that allows designated market makers to increase their positions so they can continue to provide liquidity.

On 16th September 2026 at 12:00 UTC, we will delist and settle all remaining derivatives contracts: 4 Perpetual Swap contracts and 4 Futures contracts (please see the lists below).

The Perpetual Swap contracts will be settled early at 12:00 UTC on 16th September 2026 ( “T_settle”), according to the standard practice described in our Exchange Guide. 

The timeline for the delisting process will be as follows:

The contracts will trade as normal until 04:00 UTC on 16 September 2026 (“T_start”).

At T_start 04:00 UTC on 16 September 2026:

• The Funding Rate, F₀,will be calculated as normal using prices from the previous eight  hours. 

• After T_start, the Funding Rate will no longer be calculated and the next Funding Rate set to 0.

• The relevant Contract Specification pages will display early settlement information.

At T_settle 12:00 UTC on 16 September 2026:

• The relevant contracts will expire, all trading will cease, and all open orders will be canceled. 

• Funding, calculated using F₀,will be exchanged (longs pay shorts if F₀ > 0 and shorts pay longs if F₀<0). 

• All open positions in the relevant contracts will be closed out using the relevant Settlement Prices. 

• No fees will be charged for settlement. 

• Once a contract has expired, the lifetime profit and loss of that contract will be added to the user’s Bitcoin balance for XBT margined contracts or Tether balance for USDT margined contracts, and this contract will no longer appear on the Positions section. 

The Futures contracts will be settled early according to the standard practice described in our Exchange Guide.

The Settlement Price Adjustment Rate has been determined using the 30 minute Time Weighted Average of the Fair Basis from 07:30 UTC to 08:00 UTC on 4th September 2026, applied to the time period between the original settlement time and the early settlement time.

The decision to delist these contracts has been made due to the decision to close the BitMEX exchange.
