CoreWeave (CRWV) stock has more than doubled since its March 2025 IPO, but the headlines this week aren’t about the rally — they’re about who’s been cashing out.

CoreWeave, Inc. Class A Common Stock, CRWV

Bloomberg reported Tuesday that the company’s three billionaire co-founders — Michael Intrator, Brannin McBee, and Brian Venturo — have collectively sold more than $2.3 billion worth of stock since the lockup period expired in August 2025.

CRWV was trading around $101 at the time of writing, up roughly 1.97% on the day.

The sales were conducted under 10b5-1 trading plans, pre-arranged programs that let executives sell stock on a schedule to avoid insider trading concerns.

Brian Venturo, CoreWeave’s Chief Strategy Officer, has been the most active seller. He’s offloaded over $1.1 billion in stock since August, ranking him as the second-largest insider seller by value in the US so far this year, according to data from Washington Service.

Intrator comes in at seventh on that same list.

Together, the founders have trimmed their combined holdings by nearly a quarter. That said, they still own about 18% of the company. Intrator remains the largest individual shareholder at 10.4%.

Magnetar Also Trims Position

The founder selling isn’t the only big exit. Magnetar Financial, one of CoreWeave’s largest institutional backers, has sold more than $5.5 billion in CRWV stock since the lockup expired — cutting its stake roughly in half. The alternative asset firm now owns about 9.7% of outstanding stock.

Paul Meeks at Freedom Capital Markets called the insider sales “obviously bad optics,” though he still believes the stock is undervalued. His price target sits at $151, nearly 50% above current levels. Most analysts tracked by Bloomberg remain bullish.

The Business Behind the Selling

CoreWeave operates nearly 50 data centers across North America and Europe, leasing Nvidia GPUs to customers including Microsoft and OpenAI.

The company has been spending aggressively. Total debt hit nearly $25 billion in Q1, with around a quarter of revenue going toward interest payments. No profitable quarter yet.

Investors pulled back after Q2 guidance came in below expectations, despite a Q1 in which revenue more than doubled year-over-year.

CFO Nitin Agrawal, who has sold $11.7 million of his own stock since the lockup — a 21% reduction in his stake — said at a Jefferies conference last month that the company is “incredibly comfortable in the long-term margin trajectory.”
