Bitcoin's biggest options expiry of 2026 settles near $85,000

Nearly $16 billion in bitcoin options expired on the Deribit exchange on Friday, the largest single settlement of 2026. Bitcoin barely moved. It held near $85,000 through the event and into the weekend.

The quarterly expiry settled at 08:00 UTC on Friday, September 25, 2026, according to figures from Deribit reported by CoinDesk. About $15.9 billion in bitcoin contracts and $2.1 billion in ether contracts came due. That one bitcoin batch equaled roughly 37% of all outstanding bitcoin options on the venue, which Deribit put near $43.5 billion.

What expired, and how traders were positioned

Positioning tilted toward higher prices going in. Deribit's data showed a put-to-call ratio of 0.69, which means traders held far more bets on a rise than on a drop. Call options worth about $9.4 billion were due to expire, and roughly 55% of those sat in the money heading into the expiry. Puts, the bets on a fall, made up the smaller side at about $6.4 billion. With bitcoin above $85,000, most of them expired worthless.

Ether settled the same morning. About $2.1 billion in ether options expired alongside the bitcoin batch, a fraction of the bitcoin figure but still a sizable quarter-end reset for the second-largest crypto asset.

Luuk Strijers, Deribit's chief executive, called it one of the largest quarterly expiries of the year. Jean-David Pequignot, the exchange's chief commercial officer, said open interest was 'heavily concentrated at the $85k, $90k, $95k, and $100k call strikes'. The independent data platform The Block put the same expiry's open interest near $15.1 billion, a little below Deribit's own tally.

A call-heavy book is not a forecast. It shows where traders parked money, not where the price has to go. Traders can be wrong in size.

Why bitcoin stayed pinned near $85,000

Max pain for this expiry sat at $75,000, the price at which the most contracts would have expired worthless. Bitcoin spent the week more than $10,000 above that, near $85,500 on Tuesday, according to CoinDesk. It never closed the gap.

Large expiries can tug the price toward the strikes with the most open interest, as dealers who sold the options adjust their hedges into settlement. The tug was weak. The distance between spot and max pain was too wide to close in a few days, and the call-heavy book gave dealers little reason to sell into the move.

Deribit did not say how much of the expiring interest rolled forward into the October and December contracts. There is no clean public read yet on how dealers are unwinding the hedges they built around Friday.

What to watch

The calm may not last. Strijers noted that once the hedging tied to a big expiry rolls off after settlement, the pinning effect fades and short-term swings can pick up. Bitcoin traded near $84,800 at 08:17 UTC on Sunday, September 27, 2026, according to CoinGecko, with ether near $2,718. Traders will also watch whether the call strikes that dominated this expiry, from $85,000 up to $100,000, get rebuilt in the December book or quietly fall out of the picture. The next large Deribit quarterly expiry lands at the end of December. Until then, no anchor.
