CoreWeave closed at USD 88.57, rising 1.66%.

A $10.10 million long-dated call buy dominated Thursday’s options tape, while a $4.90 million same-side double short put sale collected premium. The oversized call purchase signals strong upside conviction, and the short put structure shows willingness to monetize volatility. Together, the largest trades lean bullish, though the put sale adds defensive nuance to an otherwise constructive flow picture.

Options Indicators

CoreWeave’s implied volatility is 78.88%, and although the absolute IV level is high, its IV percentile is just 9.96%, which indicates that current option pricing sits near the low end of its own recent range. In other words, volatility is on the low side relative to where it has traded before, so options appear cheaply priced rather than expensive. The IV/HV ratio of 1.11 also suggests implied volatility is only modestly above realized volatility, pointing to option premiums that are not overly stretched.

The Call/Put volume ratio is 1.70.

Large Trades

A net-credit put spread-style sale worth $4.90 million was one of the standout large trades, consisting of the same-direction sale of 2,500 Jan. 15, 2027 $90.00 puts and 2,500 Jan. 15, 2027 $70.00 puts. This is a same-side double short put structure, best understood as a premium-collection strategy with a neutral-to-bearish tone, and its size should be measured by the preprocessed net credit of $4.90 million. With CRWV referenced at $88.57, the short $90.00 put is in the money while the short $70.00 put is out of the money, indicating the trader is willing to take on downside assignment risk while collecting option premium and expressing a view that the stock is unlikely to suffer a deep breakdown toward the lower strike over the life of the trade.

A call purchase worth $10.10 million was the single largest outright leg of the day, with 5,000 Jan. 21, 2028 $125.00 calls bought. With the stock at $88.57, the $125.00 strike is out of the money, so this is a clear bullish upside bet using long-dated optionality. The buyer is paying significant premium for extended exposure to a large upside move over time, suggesting conviction that CRWV can appreciate materially before expiration while limiting risk to the premium paid.

Overall, the bulk-order flow leans bullish. The dominant signal comes from the oversized long-dated call purchase, which reflects strong upside appetite and outweighs the more defensive or income-oriented positioning seen elsewhere. While the large short-put combination introduces some neutral-to-bearish caution and highlights willingness to monetize volatility rather than chase immediate upside, the broader character of the largest trades still points to constructive sentiment, with institutional activity favoring long-term upside participation over outright downside protection.

Strategy Reference

For sellers seeking low assignment probability against the current IV backdrop, a short put below the $70.00 strike in nearer expirations may offer a balance of premium and cushion; for bullish traders unwilling to post large margin, a Jan. 2028 $100.00/$125.00 call spread reduces cost while retaining long-dated upside exposure.
