CoreWeave (CRWV) co-founders Michael Intrator, Brian Venturo and Brannin McBee have sold $3.3 billion in company shares since its March 2025 initial public offering, including $2.4 billion in 2026, Bloomberg reported. Shares sank over 12%, extending losses from earlier this week as concern mounted around its debt and credit risk.
