According to @BullTheoryio, $7.1 trillion worth of US stock and ETF options expire today, marking the largest triple-witching event on record. According to @BullTheoryio, triple witching is a quarterly expiration that occurs on the third Friday of March, June, September, and December, concentrating expirations into a single session. According to @BullTheoryio, the day features three types of derivatives expiring on the same day, creating an unusually large notional roll-off in US equities and ETF options. According to @BullTheoryio, crypto-focused traders can treat today’s record US options expiry as a key calendar event to monitor alongside US market hours.

According to The Kobeissi Letter, $6.8 trillion worth of options on stock indexes, ETFs, equity index futures, and individual stocks are set to expire today, marking potentially the largest 'triple witching' options expiration on record (source: @KobeissiLetter, June 20, 2025). Traders should prepare for significant market volatility, as this convergence of expiries can trigger sharp moves in traditional markets, which historically have spillover effects on the cryptocurrency sector, including BTC and ETH. Heightened volatility in equities often leads to increased risk-off behavior or liquidity events, impacting crypto trading volumes and price action.
