Nvidia CEO Jensen Huang has a message for anyone nervously watching CoreWeave's balance sheet: the company is getting financially stronger.

Speaking at an event in Stockholm on October 15, 2026, Huang said CoreWeave's cost of capital is falling and that Nvidia does not need to backstop the company. Coming from the CEO of the chipmaker that supplies CoreWeave's GPUs and owns a slice of its equity, that is less a neutral review than a vote of confidence from an invested party.

A Defense Mounted During a Rough Week

The timing was not accidental. CoreWeave shares dropped 15% in a single session in mid-October 2026, and that slide arrived alongside a jump in the cost of the company's five-year credit default swaps.

For those unfamiliar, a credit default swap works like an insurance policy on a borrower's debt. When the premium on that insurance rises it means the market sees a higher chance the borrower could struggle to pay.

Huang's remarks, reported by Bloomberg, were aimed squarely at that anxiety. His core argument is that CoreWeave can now borrow more cheaply than before, which matters a great deal for a company whose business model runs on borrowed money. Cost of capital is the rate a company pays to access financing, and for a business constructing data centers largely with debt, movements in that rate shape what each new facility ultimately costs to deliver.

The Numbers Behind the Worry

In the second quarter of 2026, CoreWeave spent $6.42 billion on equipment and property. Over the same period, it generated $679 million in operating cash flow. That shortfall between capital outlays and internally generated cash is why continued access to financing sits at the center of the company's expansion, and why shifts in borrowing costs draw outsized scrutiny.

The cost of carrying that financing is climbing too. CoreWeave's net interest expense rose from $267 million to $640 million, more than doubling.
CoreWeave has secured more than $35 billion in financing this year. By the end of June 2026, its total debt and lease obligations stood at approximately $52 billion.

The counterweight is a revenue backlog that exceeds $100 billion, meaning customers have already committed to future spending that dwarfs the company's current obligations, at least on paper. The pace at which those commitments convert into revenue and cash, set against the size of the debt stack, is the underlying tension in the debate over CoreWeave's finances.

Nvidia's Skin in the Game

Nvidia has invested over $2 billion in CoreWeave stock. That includes a share purchase at $87.20 in January 2026, which raised Nvidia's stake to about 10%. Nvidia has also signed a $6.3 billion agreement to purchase any unsold computing capacity from CoreWeave through 2032.

That capacity deal functions as a safety net: if CoreWeave builds data center capacity that customers do not rent, Nvidia has agreed to buy it. Which makes Huang's comment that Nvidia does not need to backstop CoreWeave a little more nuanced than it first sounds.

How CoreWeave Got Here

CoreWeave went public in 2025 and has spent the time since aggressively expanding capacity alongside Nvidia. The strategy centers on what the industry calls AI factories, large data centers designed specifically to run AI workloads at scale. The model helps explain both the opportunity and the strain: capacity has to be built and paid for before the customer revenue arrives, which puts the company's financing terms on center stage.

What This Means for Investors

The interest expense trend is the number to watch. A jump from $267 million to $640 million suggests borrowing costs are biting harder as the debt pile grows, even if Huang is right that the rate CoreWeave pays on new money is coming down.

Upcoming quarterly reports will show whether operating cash flow narrows the gap with capital spending, and what happens to the cost of insuring CoreWeave's debt in the credit default swap market that flagged concern earlier this month.

There is also a circularity question that investors will keep asking. Nvidia sells GPUs to CoreWeave, owns about 10% of CoreWeave, and has agreed to buy CoreWeave's unsold capacity. When that same company says CoreWeave is in good shape, skeptics will reasonably weigh the endorsement against the relationship.
