Bitcoin is facing a major derivatives event on Friday, Sept. 25, with roughly $15.9 billion of Bitcoin options and $2.1 billion of Ethereum options scheduled to expire on Deribit at 8:00 UTC. The combined notional value is close to $18 billion, making it the largest crypto options expiry of 2026, according to current market data.
Bitcoin was trading around $84,500 Wednesday, after reaching above $87,000 earlier in the week. The latest retreat has put the options settlement at the center of attention as traders assess whether the recent rally can hold once the hedging activity surrounding the contracts disappears.
The important point is that the $18 billion figure represents the notional value of the contracts, not $18 billion that will suddenly enter or leave the market on Friday. Decrypt's latest Deribit data shows about 182,000 BTC in expiring options, consisting of roughly 106,200 calls and 75,900 puts.
Why Bitcoin Is Falling Ahead of Friday's Options Expiry
The current options structure is not uniformly bearish. Bitcoin's put-to-call ratio is about 0.71, meaning there are substantially more calls than puts in the expiring contracts. Coinbase Markets separately puts the Bitcoin open-interest put/call ratio at 0.66, with recent trading volume even more heavily tilted toward calls at 0.37.
The largest concentrations of Bitcoin call open interest are around $90,000 and $100,000, while significant defensive put positions are clustered around $60,000, $70,000 and $75,000. That creates a wide range of positions that could influence dealer hedging as Bitcoin moves toward or away from those strikes.
Deribit CEO Luuk Strijers said dealer hedging helped support Bitcoin's move from roughly $80,000 to $87,000. When dealers are short calls, rising Bitcoin prices can require them to purchase additional spot Bitcoin to maintain their hedges.
That dynamic can work in reverse after expiration. Once the contracts settle, some of the associated hedging activity disappears or moves into later-dated contracts. That can increase short-term volatility, but it does not establish that Bitcoin must continue falling through Friday.
What Happens to Bitcoin After Friday?
Deribit's current data puts the max-pain level around $76,000, substantially below Bitcoin's current price. Max pain represents the theoretical price at which the greatest amount of options would expire worthless; it is not a reliable forecast of where Bitcoin will settle. Decrypt specifically notes that the level has a mixed record as a predictor.
The expiration also arrives alongside other market events. US durable-goods data and the University of Michigan's final September consumer-sentiment reading are scheduled around the same period, while September Bitcoin futures on CME are also due to settle Friday.
That means Bitcoin's direction after the options expiration will depend on more than the options themselves. The Federal Reserve's recent rate increase to 3.75%-4%, Treasury yields, economic data, and demand for risk assets can all influence crypto prices.
For now, the options market shows a call-heavy structure rather than a clear bearish positioning signal. The immediate risk is increased volatility as the contracts expire and dealer hedges are adjusted.
