What is the impact of a record $18 billion Bitcoin options expiry today?
Bitcoin options expiry of $18 billion is a record-sized notional event that can suppress volatility into the cut-off and produce a clearer directional move within 24–72 hours after expiration. Elevated open interest concentrates risk and can amplify moves as dealers hedge.
How do options expiries typically affect Bitcoin price action?
Options expiries often compress volatility leading into the expiry, then create directional moves once positions are settled. Bitfinex analysts (quoted in plain text) note that large expiries frequently suppress volatility pre-cutoff and trigger clearer trends in the subsequent 1–3 days.

Why did analysts call today’s $18 billion expiry “record-setting”?
Analysts labeled the event record-setting because $18 billion notional is unusually large for a single-cycle expiry. Such size increases the potential impact on liquidity and dealer hedging flows, raising the odds of post-expiry directional moves.
What data shows elevated options risk going into October?
Crypto data aggregator Coinglass (plain text source) estimates roughly $78.9 billion of Bitcoin open interest across derivatives. On Deribit (plain text source), more than $8 billion of BTC options are slated to expire on October 31, highlighting concentrated October risk.
| Metric | Value | Significance |
|---|---|---|
| Today’s notional expiry | $18,000,000,000 | Record single-cycle notional |
| Total BTC open interest | $78,900,000,000 | Elevated systemic risk |
| Deribit Oct 31 expiries | > $8,000,000,000 | Concentrated October exposure |
How do long convexity positions influence post-expiry moves?
Long convexity means buyers of certain options can see outsized gains if Bitcoin rallies sharply. Dealers who sold those options may hedge by buying spot BTC on rallies and selling on drops, which magnifies intraday swings and creates choppy markets.

Users on Myriad, the prediction market owned by Dastan (plain text), show a narrow tilt to bearish sentiment — approximately 51% expect lower daily closes over the weekend versus 49% bullish. Sentiment metrics can add context but are not a substitute for position-level risk analysis.
Traders should review position-level exposure, consider using options or spot hedges to limit tail risk, and avoid concentrated directional bets immediately before expiry. Keep position sizes manageable and monitor funding and liquidity.
Watch for concentrated strikes with heavy open interest, rapid changes in implied volatility, and dealer delta hedging flows. Data from derivatives aggregators and exchange open-interest reports provide early warnings.
