CoreWeave co-founders Michael Intrator, Brannin McBee, and Brian Venturo sold over $2.3 billion in stock following their August 2025 lockup expiration. The sales utilized pre-arranged 10b5-1 trading plans to manage the transactions.
The company’s share price has surged more than 150% since its March 2025 initial public offering. High demand for specialized AI computing infrastructure fueled this market growth.
These transactions reduced the founders' combined ownership by approximately 25%. The trio maintains a collective stake of roughly 18% in the firm.
Major investor Magnetar Financial also sold more than $5.5 billion in shares. This divestment halved Magnetar’s total stake to approximately 9.7%.
A company spokesperson stated the sales provided liquidity and diversification. The founders remain committed to CoreWeave's long-term growth objectives.
