NEW YORK, December 30, 2025, 17:53 ET — After-hours
- CoreWeave (CRWV) closed down 1.36% at $73.90 and slipped to $73.70 in after-hours trade.
- A filing showed Chief Strategy Officer Brian M. Venturo sold 281,250 shares worth about $22.3 million under a pre-arranged trading plan. 1
- U.S. stocks finished slightly lower in thin year-end trade, with tech mixed as investors digested Fed minutes. 2
CoreWeave shares fell 1.4% to $73.90 in regular trading on Tuesday and slipped 0.3% after the bell to $73.70.
The stock move landed as investors weighed an insider sale disclosed in a regulatory filing, a headline that can carry extra weight in holiday-thin markets when volumes are light and price swings can widen. 1
CoreWeave has become a closely watched proxy for artificial-intelligence infrastructure spending, and traders remain quick to react to signs of added share supply or shifts in sentiment around capital intensity.
In a Form 4 filed on Monday, Chief Strategy Officer and director Brian M. Venturo reported selling 281,250 Class A shares on Dec. 24 for about $22.3 million. The filing said the sales were made under a Rule 10b5-1 plan adopted on May 21. 1
A 10b5-1 plan is a pre-set trading program that allows insiders to buy or sell shares on a schedule, helping separate trades from any non-public information that may arise later.
The disclosure comes as investors remain sensitive to CoreWeave’s execution risk and heavy spending profile. In November, the company trimmed its 2025 revenue forecast to $5.05 billion to $5.15 billion after citing a delay at a third-party data center partner, while flagging 2025 capital spending of $12 billion to $14 billion.
Broader market action offered little support for high-growth tech. The S&P 500 and Nasdaq ended slightly lower on Tuesday, while Nvidia slipped 0.4%, and “trading volumes remained thin” in the holiday-shortened week, Reuters reported. “It’s just a healthy rebalancing of allocations more so than an emotionally driven sell-off,” said Mark Hackett, chief market strategist at Nationwide. 2
CoreWeave provides access to high-end graphics processing units (GPUs), chips used to train and run AI models. Nvidia has been a key partner, and CoreWeave has said Nvidia agreed to purchase any unused cloud capacity from CoreWeave through April 2032. 3
Investors are also tracking how CoreWeave funds its expansion. The company said on Dec. 9 it priced an upsized $2.25 billion private offering of 1.75% convertible senior notes due 2031, a financing that can later convert into equity and dilute shareholders. 4
What traders are watching next is straightforward: any further insider-sale disclosures, updates on buildouts at data-center partners, and signs that demand from large AI customers is keeping pace with the company’s aggressive investment cycle.
On the tape, Tuesday’s regular-session range of $73.65 to $75.86 left the stock closing near the low end of the day’s band, an area short-term traders often treat as an early support test.
CoreWeave was last at $73.70 after hours, putting the shares down about 1.6% from Monday’s close as the market heads toward the final U.S. trading session of 2025.
