CoreWeave, Inc. closed at USD 81.36 with a 1.85% increase.

The most notable flow was a massive $26.78 million short strangle centered on collecting premium, while a separate $3.91 million bear call calendar added to a cautious stance. The combination of aggressive put selling near the money, capped upside via short calls, and calendar-spread downside hedging left the aggregate institutional tone clearly negative despite the modest daily gain in shares.

Options Indicators

CRWV’s implied volatility stands at 77.84%, while its IV percentile is just 5.58%, indicating that although the absolute IV level is high, it sits near the low end of its own historical range. In other words, relative to where this stock’s options have typically traded, current volatility is on the cheap side rather than elevated. With an IV/HV ratio of 1.14, implied volatility is only modestly above realized volatility, suggesting option pricing carries a limited premium over recent actual movement. The Call/Put volume ratio is 1.72.

Large Trades

A premium-selling combination worth $26.78 million was the largest highlighted trade, consisting of the sale of 3,000 January 21, 2028 $150.00 puts and the sale of 3,000 January 21, 2028 $170.00 calls. Because this structure contains both a Sell Put and a Sell Call rather than a buy-call/sell-put synthetic call or a buy-put/sell-call synthetic put, it is best understood as a short risk-defined volatility-style combination centered on premium collection. The trade brought in a net credit of $26.78 million, with the $150.00 put in the money versus the $81.36 stock reference and the $170.00 call out of the money. Strategically, this suggests the trader was willing to take on downside assignment risk while also capping upside participation above $170.00 in exchange for substantial upfront premium, a stance that leans more toward harvesting rich option premium than expressing outright bullish conviction.

A bearish call spread with a net debit of $3.91 million was the second featured block, built by buying 2,500 June 17, 2027 $90.00 calls and selling 2,500 October 16, 2026 $90.00 calls. Since the combination includes both a Buy Call and a Sell Call, it should be identified as a spread strategy, specifically a bear call-style calendar structure. Both legs were out of the money relative to the current stock price, and the position was initiated for a net debit of $3.91 million, indicating a directional hedge or bearish-to-cautious view rather than premium collection. The trader appears to be positioning for limited upside in the nearer term while retaining longer-dated optionality, which fits a restrained or defensive outlook on CRWV.

Overall, the large-trade flow points to a bearish market tone in CRWV. The bulk of notable activity was driven by premium-selling structures that monetize upside restraint and by additional downside-oriented positioning across the broader block tape, while the smaller bullish trades were not large enough to offset that pressure. Taken together, the figures suggest institutional participants are either expecting capped upside and elevated volatility, or actively positioning for weaker price action ahead, leaving the aggregate read on CRWV clearly negative.

Strategy Reference

For defined-risk premium sellers seeking low assignment probability, a put credit spread using the $60.00/$55.00 strikes in a nearer-dated cycle may offer a more conservative alternative to the institutional short put, while bearish traders preferring limited margin can consider a $85.00/$90.00 call credit spread rather than the large $150.00/$170.00 strangle.
