BTC Friday options expiration heats up: notional open interest doesn’t equal sell pressure: around 86,400 I won’t chase
My stance is to manage volatility first, then wait for direction—don’t mechanically treat the huge options expiration as necessarily leading to a sell-off. The topic trending on Binance Square is “#$14BBitcoinOptionsExpireFriday”, but the $14B figure is the wording within the hashtag; it doesn’t represent the unified total market size that I would recalculate right now. Based on Deribit’s publicly available API snapshot around 17:20 UTC, for the expiry date 25SEP26 there are about 134 BTC options contract series, with total open interest of roughly 185,300 contracts (BTC). Multiplying the reference underlying price shown by the interface—approximately $86,547—gives a notional value of about $16 billion. This dynamic estimate only covers that interface and timestamp; price, open interest, and the statistical scope will all change, so it can’t be used to prove the $14B is “wrong,” nor can the two be mixed into an exact total market number.
Why would it affect BTC? Deribit’s official rules show that weekly, monthly, and quarterly options typically expire on Friday between 08:00 UTC; this week corresponds to Friday 16:00 Beijing time. The final settlement price uses a 30-minute TWAP of the index from 07:30—08:00 UTC. Before expiry, market makers adjust hedges according to price, time value, and movements in the Greeks, which may amplify short-term back-and-forth around key strike levels. But open interest includes calls and puts, buyers and sellers, and combination strategies—the notional size is not the same as net sell orders. Expiration also doesn’t mean that 185,300 BTC of spot holdings will all dump at once; the direction of final cash settlement and the unwind of hedges depends on the position structure and the price at that time.
The market reaction so far looks more like a tug-of-war at high levels. On KuCoin, when I recorded it, the BTC perpetual was around $86,460; the 24-hour range was $85,066—$87,376. The full 15-minute candles for 16:00 UTC fell from 86,362 to 86,122, and at 16:45 it recovered to 86,372; it hasn’t broken above the 24-hour high yet. Funding rate is about -0.0051%—this only describes that contract’s funding rate at the time; it can’t be used to conclude that shorts are dominant or that a squeeze will happen immediately. The previous round’s condition requiring consecutive confirmations above 86,450 wasn’t stably completed—I didn’t get a fill, and there’s nothing profitable to review.
If I were trading it myself: I’m not participating right now; direction-neutral; position size 0. Only if two complete 15-minute candles close above 86,800, and then a pullback to 86,450—86,800 holds without breaking, with increased成交 volume, would I use up to 1.2% of principal to spot test-long, without opening high leverage. I’d first look for 87,200—87,400, then 87,900—88,200; on the first target, I’d cut the position by half. After entering, if price falls back to 86,300, I’d cut it by half. If a 15-minute close is below 85,950, I’d fully stop out and close. If price first breaks below 85,950 and the rebound back to 86,400 fails, the long plan is canceled. If into expiry there’s a high spike but open interest drops quickly and price still can’t hold above 86,800, I’d remain in cash.
The conditions that would invalidate my judgment aren’t the hashtag hype dropping, but rather the price being unable to confirm, changes in the expiration structure, or a sudden upgrade in macro risk. #$14BBitcoinOptionsExpireFriday #BTC
The above is only my personal market observation and does not constitute investment advice.
