NEW YORK, December 30, 2025, 12:16 ET — Regular session
- CoreWeave shares rose about 0.5% in midday trading.
- A Form 4 filing showed Chief Strategy Officer Brian Venturo sold 281,250 shares via an affiliated entity under a 10b5-1 plan.
- Traders are looking ahead to the next earnings update expected in early February, according to Zacks.
CoreWeave (CRWV) shares inched higher on Tuesday after late Monday regulatory filings disclosed stock sales tied to a senior executive and director.
The disclosures matter because CoreWeave remains a high-volume, high-volatility AI infrastructure name, and investors have been closely tracking insider selling and financing as the company scales data center capacity.
Insider trades can sway sentiment in companies like CoreWeave that require heavy upfront spending, especially after the firm warned earlier this quarter that a third-party data center delay would pressure its outlook.
The Nasdaq-listed shares were up about 0.5% at $75.27 by 12:16 p.m. ET, after trading between $74.01 and $75.83.
A Form 4 filing showed Chief Strategy Officer and director Brian Venturo reported sales of 281,250 Class A shares on Dec. 24 through West Clay Capital LLC, an entity the filing said he controls. The shares were sold in multiple transactions at prices ranging from $78.57 to $80.93 and were executed under a Rule 10b5-1 trading plan adopted on May 21, 2025, the filing showed. 1
A separate Form 144 notice listed the same 281,250-share sale with an aggregate market value of about $22.6 million and named Morgan Stanley Smith Barney as the broker. “Sales that were executed on December 24, 2025 are being reported on this Form 144 filed on December 29, 2025,” Venturo wrote in the filing. 2
Form 4 is the SEC filing corporate insiders use to report stock transactions. Form 144 is a notice filed under SEC Rule 144, which governs sales of restricted or “control” securities; it is often used to signal an insider’s intent to sell shares. A 10b5-1 plan is a pre-set trading instruction that schedules trades in advance.
AI-linked stocks were mixed on the day, with Nvidia little changed and Core Scientific down about 1%.
CoreWeave rents out computing capacity built around Nvidia chips to AI customers. In November, it cut its annual revenue forecast after a delay at a third-party data center partner and said 2025 capital spending would be $12 billion to $14 billion. 3
The company has also tapped capital markets to fund buildout, pricing an upsized $2.25 billion convertible senior notes offering earlier this month, it said. 4
Investors are now watching for any further insider filings, data center capacity updates and changes to demand signals from large customers.
The next quarterly report is expected in early February; Zacks lists Feb. 9 as the next expected earnings date. 5
