CoreWeave, Inc. closed at USD 85.76, rising 19.49% from the previous close.

Despite the sharp rally, institutional options flow displayed a starkly bearish tone. The session was dominated by aggressive premium collection, headlined by a massive $9.44 million short call at the $115 strike. This single trade, alongside other deep out-of-the-money call sales, signals a clear institutional expectation that the stock’s upside is capped, with traders positioning to harvest elevated premiums rather than chase the breakout.

Options Indicators

CRWV’s implied volatility is 115.81%, and with an IV percentile of 94.02%, current option volatility sits in a clearly elevated regime, indicating that options are priced expensively relative to the stock’s own recent history. The IV/HV ratio of 1.05 further suggests implied volatility is only modestly above realized volatility, so while premiums are rich on a percentile basis, they are not wildly disconnected from the stock’s actual movement profile. The Call/Put volume ratio is 2.76.

Large Trades

A CALL sale worth $9.44 million was the largest displayed trade, with 30,444 contracts sold at the $115.00 strike expiring on September 18, 2026. With CRWV referenced at $85.76, this call was out of the money at the time of execution, making it a bearish to capped-upside positioning trade. By selling upside exposure well above the current stock price, the trader appears to be expressing the view that shares are unlikely to rally through $115.00 by expiration, while also seeking to collect option premium as income if the stock remains below the strike.

A CALL sale worth $1.79 million was the other displayed large trade, involving 1,250 contracts sold at the $210.00 strike expiring on January 21, 2028. This strike sits deeply out of the money versus the $85.76 reference stock price, so the structure points to a bearish or at least strongly range-bound outlook over a very long horizon. Strategically, this kind of upside call sale suggests the trader is comfortable fading the probability of an extreme upside move, using the elevated strike to monetize premium while positioning for the shares to stay well below $210.00 into expiration. Overall, the large-trade flow was clearly bearish. The sentiment summary shows bearish activity overwhelmingly dominated bullish activity, and the heaviest prints were concentrated in call selling, including repeated premium-collection structures and the two displayed single-leg short calls. Taken together, the flow indicates institutional traders were more focused on selling upside, harvesting premium, and expressing skepticism about a major advance in CRWV than on positioning for sustained upside.

Strategy Reference

A trader seeking to mimic the bearish premium-collection flow with a lower capital requirement could consider a bear call spread, such as selling the $115.00 call and buying a higher strike call, to define risk while still capitalizing on the elevated IV percentile and the view that shares will remain below $115.00.
