CoreWeave Inc. insiders have sold more than $2.3 billion worth of shares since the company's March 2025 initial public offering, prompting sharp criticism from short-seller Jim Chanos. The aggressive liquidation by billionaire co-founders and top executives has raised questions about the AI infrastructure giant's long-term outlook. The sell-off comes as the stock price has more than doubled since its listing, moving from $40 per share to around $99 per share.

Chanos Sounds the Alarm

The liquidation drew scrutiny from veteran short-seller Jim Chanos, who voiced skepticism on social media platform X. He noted that the sell-off was not limited to founders, as key institutional backer Magnetar Financial LLC also reduced its holdings by half. Chanos dismissed arguments that the sales were routine profit-taking, labeling the scale of insider divestment as well above normal behavior.

The Multi-Billion Dollar Windfall

Following the expiration of the lock-up period, CoreWeave's highest-ranking insiders utilized 10b5-1 trading plans to cash out. Chief Strategy Officer Brian Venturo led the sales, unloading over $1.1 billion in stock. Co-founders Michael Intrator and Brannin McBee accounted for the bulk of the remaining sales. In the last 30 days alone, insiders sold 3.03 million shares totaling $382.41 million, with zero insider purchases recorded.

Ownership and Performance

Despite the sales, executives retain sizable stakes, with Intrator remaining the largest shareholder at 10.4%. However, overall insider ownership has dropped to 0.99%. Shares of CoreWeave have advanced 37.48% year-to-date but closed 3.83% lower at $98.45 on Tuesday. The stock is down 13.75% over the last month and has dropped 39.27% over the past year, signaling mixed market sentiment.
