CoreWeave, Inc. closed at 91.90 USD, up 7.16% from the prior session’s close.

Despite the sharp rally, an enormous $19.28 million bear call spread dominated the session, signaling that large traders are using the pop to cap upside. Alongside a $1.82 million put sale, the aggregate block flow leaned heavily bearish, with sophisticated structures overwhelmingly positioned for limited further gains and a fading rally rather than a breakout.

Options Indicators

CRWV’s implied volatility stands at 116.83%, and with an IV percentile of 94.42%, current option pricing sits in a clearly elevated regime, indicating that volatility is on the high side and options are expensively priced relative to the stock’s own recent history. At the same time, the IV/HV ratio of 0.91 suggests implied volatility is slightly below realized volatility, so while premiums are rich on a percentile basis, they are not excessively stretched versus the stock’s actual recent movement. Overall, the name is carrying very high absolute volatility, but the market’s pricing is still broadly in line with a stock that has already been moving aggressively. The Call/Put volume ratio is 1.81.

Large Trades

A bear call spread worth $19.28 million was the largest displayed trade, built by selling 7,500 August 21, 2026 $80.00 calls and buying 7,500 August 21, 2026 $95.00 calls. This is a bearish income-oriented strategy that seeks to profit if CRWV stays below the short-call strike or at least fails to rally meaningfully into expiration. Using the net-premium method, the position took in $12.56 million from the short $80.00 calls and paid out $6.71 million for the long $95.00 calls, resulting in a net credit of $5.85 million. With the stock reference price at $91.90, the short $80.00 call is in the money while the long $95.00 call is out of the money, showing the trader is capping upside risk while expressing the view that further gains should be limited.

A PUT sale worth $1.82 million involved selling 1,200 December 18, 2026 $82.50 puts, a moderately bullish trade that benefits if CRWV remains above the strike and the options expire worthless or decay in value over time. With the stock at $91.90, the $82.50 put is out of the money, so the seller is effectively expressing confidence that shares can stay above that level while collecting premium. Strategically, this can reflect willingness to accumulate stock at a lower effective entry point or simply a view that downside will remain contained.

Overall, the large-trade flow leans clearly bearish. The sentiment summary shows bearish positioning outweighing bullish activity by a wide margin, and that tone is reinforced by the dominance of call-spread structures that are designed to monetize capped upside and fading rally expectations. While there was some supportive flow through bullish structures and out-of-the-money put selling, the character and scale of the biggest trades indicate that institutional participants were primarily positioned for limited upside and a softer path for CRWV rather than a sustained breakout.

Strategy Reference

Given the steep IV percentile, premium sellers might consider the 50-delta put as a short-volatility entry, or deploy a bear call spread like the 95.00/100.00 strikes to define risk while capitalizing on the fading rally thesis.
