Circle Internet Corp. closed at $83.66, up 6.45%.
CRCL drew unusually large options activity on Friday, with a $2.00 million net-debit call calendar spread and a $1.70 million short put sale dominating the tape. The two prints combined for $3.70 million in bullish premium flow against zero bearish block trades, signaling that institutional participants are positioning for continued upside rather than hedging against a pullback.

Options Indicators
CRCL’s implied volatility stands at 88.75%, and its IV percentile is 44.62%, which places current volatility in a neutral historical zone rather than an extreme one. In other words, while the absolute IV level is high, it is not especially rich relative to its own recent range, so options appear fairly priced overall instead of clearly cheap or expensive. With an IV/HV ratio of 1.35, implied volatility is running above realized volatility, indicating the options market is embedding a noticeable premium over recent actual movement. The Call/Put volume ratio is 2.11, showing call activity was more than twice as heavy as put activity during the session.
Large Trades
A CALL calendar-style combination with a net debit of $2.00 million was the largest displayed trade, built as a three-leg call structure across the 2026-08-21 and 2026-08-28 expirations. The trader bought 4,131 contracts of the 88.0 call expiring 2026-08-28 while also buying two blocks totaling 4,131 contracts of the 82.0 call expiring 2026-08-21, making this a net premium outlay rather than a premium-collection trade. With the stock reference at 83.66, the 88.0 calls were out of the money while the 82.0 calls were in the money, so the structure appears designed as a bullish, time-spread-style directional bet that targets upside participation while positioning around different near-term and later-dated expirations. The fact that the trade was established for a net debit suggests the buyer was willing to pay upfront for upside exposure and timing optionality rather than seeking immediate income.
A short put sale worth $1.70 million was the other major print, involving the sale of 1,440 contracts of the 80.0 put expiring 2026-11-20. With CRCL at 83.66, this strike sat out of the money at execution, and the trade carries a clearly bullish or at least constructive stance: the seller is collecting premium while expressing confidence that the stock can remain above 80.0 into expiration, or is willing to accept assignment at an effective lower entry level if shares weaken. Overall large-trade sentiment was decisively bullish, with $3.70 million in bullish flow versus $0.00 million in bearish flow. The tone of the block activity points to a market that is leaning positive on CRCL, as the largest order was a net-debit call combination aimed at upside exposure and the second-largest was an out-of-the-money put sale consistent with premium collection on a stable-to-rising outlook.
Strategy Reference
For traders who share the bullish view but prefer a defined-risk setup without the upfront cost of a long calendar, a bull put spread using the 80.0/75.0 strikes in the November expiration offers a lower-margin alternative to selling the naked 80.0 put while still collecting premium on a stock that remains above 80.0. Given the large short put print already positioned at 80.0, that strike can serve as a short-term sentiment line for CRCL.
