CoreWeave closed at $91.72, advancing 4.95%.
A dominant $9.18 million long-dated call purchase at the 120.0 strike, expiring 2027-09-17, led the session’s block flow, while a $4.23 million synthetic long in 2028-01-21 further reinforced upside conviction. Both structures were out of the money at execution, and the synthetic long was even established for a $310 thousand net credit. Institutional positioning appears decisively bullish, prioritizing leveraged upside exposure over defensive hedging.

Options Indicators
CoreWeave’s implied volatility stands at 79.18%, while its IV percentile is just 11.95%, which indicates that although the absolute volatility level is high, it sits near the lower end of its own historical range. In that context, options appear cheaply priced rather than elevated, and with an IV/HV ratio of 1.50, implied volatility is running above realized volatility, suggesting the market is still assigning a meaningful premium to forward uncertainty even as current pricing remains on the low side versus its past levels.
The Call/Put volume ratio is 2.42, confirming the bullish tilt in overall option activity.
Large Trades
A CALL purchase worth $9.18 million was the standout single-leg block, with 5,000 contracts bought at the 120.0 strike expiring on 2027-09-17. With the stock reference price at $91.72, this call was out of the money at the time of execution, making it a clear bullish directional wager on substantial upside over a long-dated horizon. The use of long calls suggests the buyer was seeking leveraged participation in a future rally while keeping downside risk limited to the premium paid, a structure typically associated with conviction in medium- to long-term appreciation.
A bullish synthetic call worth $4.23 million appeared in the 2028-01-21 expiry, built through the purchase of 2,000 contracts of the 210.0 call and the sale of 2,000 contracts of the 62.5 put. Both legs were out of the money versus the $91.72 reference stock price, and together they express a strongly bullish stance similar to long stock exposure, but through options. The fact that the position was established for a net credit of $310 thousand further reinforces the aggressiveness of the trade, as the buyer gained upside exposure while collecting premium upfront, signaling confidence that shares can remain above the lower put strike and potentially trend much higher over time.
Overall, the large-trade flow was decisively bullish. The displayed trades were both upside-oriented structures, led by a sizable long-dated out-of-the-money call purchase and reinforced by a synthetic long setup that paired call buying with put selling. More broadly, the bulk-order activity showed consistent accumulation of bullish exposure with no meaningful bearish counterpart, indicating that institutional positioning is skewed toward expectations of continued upside rather than downside protection or defensive hedging.
Strategy Reference
For traders seeking income without directionally short exposure, selling the 2027-09-17 62.5 put could offer a low assignment probability given the recent bullish flow, while a bull call spread using the 120.0 and 210.0 calls may provide defined-risk upside participation with reduced margin compared to outright long calls.
