Binance Futures announced on 1 October 2026 that three USDⓈ-margined perpetual contracts — PROMPTUSDT, PUMPBTCUSDT and 1000000BOBUSDT — would be force-settled and delisted. From 08:30 UTC on 5 October no new non-reduce-only orders were accepted; at 09:00 UTC all positions were settled automatically, and the contracts were delisted once settlement completed. The notice was issued under Binance Exchange Rule 17.

The part worth reading twice is not the delisting. It is the clause covering the final hour.

Three rules for the last hour

Per the announcement, during the final hour preceding the scheduled settlement time:

  • The Futures Insurance Fund is not utilised to support the liquidation process for that contract. Ordinarily it absorbs shortfall behind a liquidation; in this hour it does not.
  • Any liquidation triggered in that period executes as a single IOC order — immediate-or-cancel, offloaded into the market in one attempt.
  • If that attempt fails to bring the position back above maintenance margin, the unfilled portion is resolved through ADL, auto-deleveraging, and handed to counterparties.

The notice also advises users to actively monitor and manage open positions during the final hour, as the period may see heightened volatility.

Stacked together the implication is concrete: liquidity ahead of a delisting is already draining, and it is in exactly that hour that slippage protection is weakest, you get one fill attempt, and the backstop withdraws. Leaving the unwind until then hands your execution price to chance.

Same contracts, different clocks

BingX scheduled the same three contracts differently: new positions blocked from 03:00 UTC on 5 October, delisting with automatic closure at 07:00 UTC — two full hours ahead of Binance.

Irrelevant if you trade one venue. If you are hedged across venues it means the legs do not vanish together: for those four hours you are closed out on one side and still carrying on the other.

What the funding data says

This is where the news actually bites for an arbitrageur.

The two highest trailing-30-day cumulative funding rates in our database belong to two of the contracts just delisted: 1000000BOBUSDT at 12.474% and PUMPBTCUSDT at 10.6713%, ranked first and second.

Both show 165 settlement periods inside the 30-day window, where other contracts on the same four-hour interval show 180. The missing 15 periods are the silence after the 5 October delisting — the period count itself records the moment (data as of 2026-10-08 06:00 +08:00, summed period by period).

For scale, on the same basis BTC perpetual funding totalled 0.060452% over the seven days from 1 to 8 October. The 30-day reading on those two names was more than two hundred times BTC’s.

What it means for a hedged book

A balanced book normally only cares whether the rate turns negative. Delisting is a different category of event: it does not change the sign, it removes one of the legs. Once the short is force-settled, the remaining spot position is outright long from that second, and the book is no longer neutral.

The data also points at a rule worth remembering: the names at the top of the funding table are often the ones on the delisting shortlist. Extreme funding means an extreme long/short imbalance, and assets capable of that imbalance are typically thin, concentrated in open interest, and volatile at the project level — which are among the criteria an exchange applies in a delisting review.

That is not a claim that high-funding names will be delisted. It is a claim that chasing the leaderboard carries a risk that is not printed on the leaderboard. The unwind sequence and timeline are in your perpetual gets delisted — how do you close the hedge leg.

What to watch next

  • The gap between announcement and execution. Four days this time. There is no fixed value; the same contract has been delisted at four venues 23 days apart.
  • How long your own instruments have been listed. Our database covers 534 symbols; two of them — BTC and ETH — have more than two years of continuous history, and the rest are overwhelmingly recent.
  • Announcements on the spot side. Delisting is not confined to derivatives; when Binance removed five margin pairs on 17 September, it was the spot leg that froze.

The usual caveat: high-funding names getting delisted will recur, and so will flat and negative funding periods. The 2022 row on our performance page is what the latter looks like, and we have not hidden it.
