CoreWeave, Inc. closed at USD 86.80, down 1.37%.

Options activity was heavy and mixed, but the overall block-flow picture tilted bearish. A large $1.34 million put sale at the 80.0 strike expiring on 2026-11-20 stood out as the biggest single-leg trade, yet it was not enough to offset a net-negative institutional tape. The featured package was a calendar-style put spread that collected a $580,500 net credit across the 2026-08-28 and 2026-09-04 expirations, while additional bearish premium-selling on the call side reinforced a cautious-to-negative institutional stance rather than a clean upside breakout signal.

Options Indicators

CRWV’s implied volatility is 76.94%, while its IV percentile is just 3.98%, which indicates that although the absolute IV level appears high, it sits near the bottom of its own historical range. In other words, current option pricing is relatively cheap versus where implied volatility has traded in the past, and the IV/HV ratio of 0.69 further suggests implied volatility is running below realized volatility rather than carrying a rich premium. Overall, this points to options that are on the inexpensive side from a historical-volatility pricing perspective.

The Call/Put volume ratio is 1.38.

Large Trades

A calendar-style put spread package with a net credit of $580,500 was one of the day’s featured large trades, built through a four-leg put combination across the 2026-08-28 and 2026-09-04 expirations. Structurally, this is a put spread strategy rather than a synthetic position, mixing short 92.0 puts and long 90.0 puts in the later expiry with additional short 91.0 puts and short 89.0 puts in the earlier expiry. Because the preprocessed data classifies the package at a net credit of $580,500, the trade appears designed primarily for premium collection, likely expressing a view that CRWV will remain relatively stable or avoid a sharper downside move across the near-term expirations. With all listed strikes above the $86.80 reference price, the structure leans on in-the-money put activity and looks more like a nuanced volatility-and-timing trade than a simple outright directional bearish bet.

A put sale worth $1.34 million was the largest outright single-leg trade displayed, with 1,440 contracts sold at the 80.0 strike expiring on 2026-11-20. That strike sits out of the money versus the $86.80 stock reference, so the seller is effectively expressing a moderately bullish or yield-enhancing stance, collecting premium while signaling comfort with potential assignment at a lower level. Even so, the broader large-trade picture still tilts bearish overall: despite this sizeable bullish short-put position, the full block flow remains net negative, driven by heavier downside-oriented put activity and additional bearish premium-selling on the call side. Taken together, the large orders suggest institutional sentiment is cautiously bearish, with traders willing to sell selective downside premium at lower strikes but still positioning overall for pressure or instability in CRWV rather than a clean upside breakout.

Strategy Reference

For a low assignment probability with a premium-collection bias, a seller could consider the 70.0 put in the 2026-11-20 expiry, which sits well below the 80.0 strike that already attracted $1.34 million in sold premium; alternatively, a short put vertical such as selling the 80.0/70.0 put spread in that expiry can reduce margin requirements while still capturing a meaningful credit, though it caps the maximum gain and leaves more residual downside exposure than a simple cash-secured put.
