CoreWeave's three co-founders sold a large block of shares during the same week the company's credit risk surged to an all-time peak, with the cumulative cash-out and the warning signals from credit markets now fueling deeper doubts about the sustainability of the high-leverage financing model underpinning AI computing power.
According to reports, since its March 2025 IPO, CoreWeave, Inc. (NASDAQ: CRWV) co-founders Michael Intrator, Brian Venturo and Brannin McBee have sold a cumulative $3.3 billion worth of company stock, with $2.4 billion cashed out in 2026 alone.
After the news emerged, CoreWeave shares plunged 15.46% on Wednesday in a single session and remained under pressure on Thursday. The backdrop to the founders' large-scale selling is the simultaneous deterioration of CoreWeave's credit risk indicators: the five-year credit default swap (CDS) spread, which measures the company's credit risk, briefly rose to 1,194.5 basis points in the week of October 14, the highest intraday level on record, implying a probability of debt default within five years exceeding 60%.
Analysts noted that the three founders understand the company's debt structure, customer contract duration arrangements and the depreciation rate of GPU assets better than any outside investor. In the same week that the CDS spread hit a record high and the company publicly talked about "unlimited capital," they sold $2.4 billion worth of stock within 12 months. Nearly 40% of McBee's personal wealth is currently held in cash and equivalents.
The founders chose to cash in some of their equity, while the bond market chose to price in default risk — both moves point in the same direction. Analyses by research firms CreditSights and DA Davidson both point to the same structural concern: in a scenario of overbuilding in computing power, the logic of high-leverage expansion will face fundamental challenges.
A look at the scale of the founders' selling and changes in their holdings
The three founders' selling has been particularly striking at the quantitative level.
Intrator has sold more than $907 million worth of company stock since January 1, 2026, making him one of the five largest insider sellers among U.S. companies over the past two quarters. Since the IPO date, he has sold shares equivalent to 16.5% of his undiluted equity.
McBee's selling has been the largest of the three. Since the IPO, he has sold a cumulative $1.06 billion worth of stock, including $577 million in 2026 alone, together equivalent to 40.4% of his undiluted holdings at the time of the IPO. According to the Bloomberg Wealth Index, nearly 40% of McBee's personal wealth is currently held in cash and equivalents.
Venturo sold $734 million worth of stock in the second quarter of 2026 alone, making him the second-largest insider seller among U.S. companies in that period. His cumulative cash-out since the IPO has exceeded $1.2 billion, equivalent to selling more than 35% of his holdings at the time of the IPO.
It is worth noting that before the company went public, the three had already cashed out a combined $488 million through two tender offers in 2023 and 2024.
In response to the selling, a company spokesperson said the three founders still collectively hold about 20% of the company and rank among the top six shareholders, and that all sales were pre-arranged and fully disclosed in accordance with 10b5-1 trading plans, describing them as "personal financial planning decisions any responsible founder with a concentrated stake would make."
CoreWeave's share price has traced a highly volatile path. Within three months of the IPO, the stock surged roughly 359% from its offering price at one point, Intrator's personal net worth briefly reached $11.8 billion, and the three entered the Bloomberg Global 500 Rich List.
However, the stock subsequently fell more than 60% cumulatively from its June 2025 peak, with a decline of about 50% over the past year. The three founders' combined paper wealth has evaporated by about $15 billion from the peak.
But through continued selling, they have locked in $3.3 billion in cash. According to Bloomberg calculations, at the current share price, the market value of the shares they have sold is nearly one-third lower than the pre-tax cash they raised — meaning the timing of the sales objectively protected a considerable portion of their wealth.
A historic warning from the credit market
The backdrop to the founders' large-scale selling is the simultaneous deterioration of CoreWeave's credit risk indicators.
On October 14, McBee said in an interview with the Financial Times that the company is seeking "unlimited" funding from insurers to support its AI computing expansion, describing such capital as "unlimited, that's all the money in the world." The next day, CoreWeave's five-year CDS spread briefly touched an all-time intraday high of 1,194.5 basis points, with the credit market implying a five-year default probability of more than 60%.
At the same time, the company's debt has continued to swell. As of the end of June 2026, CoreWeave's total combined debt and lease obligations had reached about $52 billion. In August 2026, the company raised its annual capital expenditure forecast by $4 billion to as much as $39 billion, mainly for purchasing GPUs and expanding AI computing infrastructure. Visible Alpha consensus forecasts show that between 2026 and 2028, CoreWeave's cumulative negative free cash flow will reach $71 billion.
Several analysts have raised specific questions about CoreWeave's financing structure.
DA Davidson analyst Gil Luria previously called CoreWeave a "subprime-like" asset in the AI space. He pointed out that CoreWeave's borrowing cost is as high as about 9%, while its return on investment is only about 1%, and even if it reaches the company's target return of 4% to 5%, it still cannot cover its financing cost. Luria likened the model to "borrowing at a 9% interest rate to buy U.S. Treasuries yielding 5%," arguing that every step destroys value.
CreditSights analyst Jordan Chalfin pointed to another structural problem: a maturity mismatch between CoreWeave's long-term data center leases and its customers' short-term contracts. "Once there is overbuilding in computing power, what reason would customers have to renew with CoreWeave?"
The divergence between Jensen Huang's endorsement and credit market pricing
It is worth noting that in the same week the bond market priced CoreWeave's default probability at more than 60%, Nvidia CEO Jensen Huang offered a very different judgment in an interview in Stockholm.
"CoreWeave's strength is growing every day," he said. "I'm very optimistic. In fact, their cost of capital is coming down." He also said Nvidia has no need to provide financial support to CoreWeave.
Nvidia holds about a 10% stake in CoreWeave, serving as both its GPU supplier and its second-largest shareholder, while also committing to purchase $6.3 billion worth of cloud services from CoreWeave. This multi-layered relationship has raised market concerns about "circular financing" — a chip supplier investing in a downstream customer, which then uses those funds to buy the supplier's products, potentially inflating the apparent scale of AI infrastructure demand.
Huang's optimistic remarks stand in sharp contrast to the risk signals emanating from the credit market, but he did not provide specific financial data to support the judgment that "the cost of capital is coming down."
