(Bloomberg) — Three co-founders of CoreWeave Inc. have sold $3.3 billion of the company’s stock since last year’s IPO, taking money off the table as rising credit risks and investor wariness of AI spending spark stock volatility.

Michael Intrator, Brian Venturo and Brannin McBee joined the Bloomberg Billionaires Index of the world’s 500 richest people last year after CoreWeave’s shares soared following its IPO in March 2025. The stock gained 359% from the offering price to peak three months later, bringing Intrator’s net worth to $11.8 billion.
While the company’s shares have fallen more than 60% from that high point, the trio has raked in billions, including $2.4 billion this year alone. At today’s closing price, the shares they have sold since the IPO would be worth nearly a third less than the pre-tax proceeds from selling their shares.
“Our co-founders remain three of CoreWeave’s six largest shareholders, together owning approximately 20% of the company,” a company spokesperson said in an emailed statement. “They make personal financial planning decisions that any responsible founder with concentrated holdings would make. All sales are planned in advance, fully disclosed and completely standard.”
CoreWeave shares fell 15% on Wednesday before rebounding slightly on Thursday. The drop came as the company’s credit risk hit a record high after McBee spoke of using “unlimited” capital from insurers in an interview with the Financial Times.
Share sales
After cashing out less than $70 million in stock last year, Intrator has stepped up the pace of its sales in 2026, divesting more than $907 million in company stock since Jan. 1, according to data compiled by Bloomberg from filings.
That makes him one of the five biggest insider sellers at a U.S. company in each of the last two quarters. It sold the equivalent of 16.5% of its undiluted shares as of the IPO date.
Percentage-wise, McBee has sold even more: Its sales of $1.06 billion since the IPO, including $577 million this year alone, represent a 40.4% decline from its undiluted stake when the company went public. Nearly 40% of McBee’s wealth is now held in cash and equivalents, according to the Bloomberg Wealth Index.
