CoreWeave, Inc. closed at $99.83, up 11.72%.

The session was defined by a $4.76 million long-dated put combination that dominated the options tape, dwarfing a comparatively modest $805,000 bull call spread. While the stock rallied sharply, institutional option flow leaned heavily bearish, with large traders positioning for a severe drawdown over a multi-year horizon rather than chasing the upside momentum.

Options Indicators

CRWV’s implied volatility stands at 85.05%, but its IV percentile is only 13.94%, which indicates that despite the high absolute IV level, current implied volatility sits near the lower end of its own historical range. In other words, volatility is on the low side relative to where this name has typically traded, and options appear cheaply priced rather than expensive. The IV/HV ratio of 0.97 also suggests implied volatility is roughly in line with recent realized volatility, reinforcing the view that current option premiums are not stretched.

The Call/Put volume ratio is 2.04.

Large Trades

A put-buying combination worth $4.76 million dominated the tape, consisting of two long 35.0 puts with expirations on 2027-12-17 and 2028-06-16, and it should be read as a same-direction long put structure rather than a synthetic position. The trade carried a net debit of $4.76 million, with both legs out of the money versus the $99.83 reference stock price, making it a lower-strike downside expression that targets a major drawdown over a longer horizon. Strategically, this is a directional bearish volatility bet: the buyer is paying premium for convex downside exposure, suggesting concern about a severe future repricing rather than a near-term hedge around current spot.

A bull call spread with a net debit of $805,000 was the other featured large trade, built by buying the 130.0 call expiring 2026-10-02 and selling the 135.0 call expiring 2026-09-18. Both call strikes were out of the money relative to the current stock price, so the structure represents a defined-risk upside bet that looks for appreciation while capping gains above the short-call strike area. The net debit indicates the trader paid premium to express a bullish view, but the spread format also shows cost control and a willingness to trade away unlimited upside in exchange for cheaper exposure.

Overall, the large-order flow leans bearish. While there was a meaningful bullish call spread and some additional call buying in the broader block activity, the standout trade was the much larger long-put combination, and the aggregate flow reflects heavier downside positioning than upside speculation. In practical terms, institutional activity appears to be signaling caution on CRWV, with the dominant message being concern about future weakness and demand for downside exposure outweighing bullish participation.

Strategy Reference

For investors seeking premium with a lower assignment probability, selling out-of-the-money puts below the 35.0 strike area could align with the low IV percentile environment, while more cautious traders may prefer a defined-risk bear put spread using nearer-dated out-of-the-money strikes to avoid the capital burden of naked short options.
