Six-Figure Strikes and a $15.6B Notional Nap: Friday's Bitcoin Options Expiry, Decoded

Roughly $15.6 billion in Bitcoin options are set to expire on Deribit at 08:00 UTC Friday, with an additional $2.1 billion in Ether options settling at the same time, according to Deribit CEO Luuk Strijers. The Bitcoin leg covers about 182,000 BTC in open contracts, split into 106,200 calls and 75,900 puts for a put-to-call ratio of 0.71 — a tilt Strijers described as "call-heavy, with a put/call open-interest ratio of 0.69 — positioning that was built for higher prices." The Bitcoin expiry will remove 37% of Deribit's outstanding BTC open interest, which stood near $43.5 billion as of reporting, based on figures attributed to Deribit.

None of the $15.6 billion represents cash changing hands. It is a notional figure, derived by multiplying open contracts by the spot price. Roughly $9.4 billion of the Bitcoin call notional sits in the money, while puts are almost entirely out of the money. Bitcoin ($BTC) was trading near $85,000 with ether ($ETH) at $2,657.46. Deribit's dashboard puts max pain — the strike at which the largest share of contracts would expire worthless — at $76,000, roughly $9,000 below the prevailing BTC price.

Strike concentration shows where hedging pressure is most likely to cluster. The busiest level is $70,000, where Deribit's data shows the largest call position at 8,705 BTC and the largest put position at 7,653 BTC. On the call side, the next-heaviest positions sit at $90,000 (7,222 BTC) and $100,000 (6,950 BTC). On the put side, the largest defensive bets cluster at $60,000 (5,571 BTC) and $75,000 (4,257 BTC). Firms that sold those contracts must hedge their exposure by buying or selling actual Bitcoin as price moves; once settlement clears, that hedging flow largely evaporates, with some positions rolling into the next quarter.

The expiry does not land in isolation. U.S. durable goods orders and the University of Michigan's final September sentiment reading are scheduled within hours of the settlement, and CME's September Bitcoin futures expire the same day at 15:00 UTC. The Federal Reserve raised its target range to 3.75%–4.00% on Sept. 16, a backdrop that gives any surprise in those releases outsized weight for rate-sensitive assets like Bitcoin. September itself carries a historical headwind: Bitcoin has closed the month lower in eight of the past 13 years, a pattern tracked as "Red September."
