Nvidia Corporation will act as a guarantor for CoreWeave Inc.'s lease payments to help the AI infrastructure specialist secure financing for its massive data centre buildout, according to an analyst briefed on the matter. This move represents a significant deepening of the financial ties between the world's most valuable chipmaker and one of the fastest-growing "neo-cloud" companies.

The arrangement was disclosed by a CoreWeave executive during a call with analysts in late February, Alex Platt, a research analyst at D.A. Davidson, told Business Insider. The executive likened the planned support to a recent guarantee extended by Google to partner Fluidstack for a Texas data centre project.

Deepening Financial Commitment

This lease payment backstop adds to Nvidia's substantial existing support for CoreWeave. Last year, Nvidia agreed to purchase up to $6.3 billion of CoreWeave's computing capacity if it remained unsold. The chipmaker has also bought billions of dollars worth of CoreWeave shares, including a $2 billion stock purchase announced on the same day as the analyst call.

A CoreWeave spokeswoman confirmed the strategic partnership, stating the company would "selectively partner with NVIDIA and leverage NVIDIA's financial strength to accelerate our procurement of land, power, [and] shell." She emphasised this support "should not be interpreted as the primary mechanism" for accessing capacity, nor as an indication the company cannot procure infrastructure independently.

Financing the AI Buildout

The guarantee is a crucial tool as CoreWeave confronts immense capital expenditure. Moody's Investors Service forecasts the company could spend over $30 billion on capital expenditures in 2026, more than double its expected 2025 outlay. This spending is fuelling rapid growth; CoreWeave aims to have 850 megawatts of operating data centre capacity by the end of 2025, up from 590 megawatts at the end of Q3 2025, according to Morgan Stanley.

Nvidia's backing, with its strong credit rating, is expected to make it easier for CoreWeave to attract lenders and potentially reduce borrowing costs for specific projects. This comes as CoreWeave also seeks other innovative financing, including arranging $8.5 billion in debt based on customer contracts with Meta Platforms Inc., as reported by Bloomberg.

Addressing Investor Concerns

Analyst Alex Platt noted the news has initiated a "pretty stark shift in sentiment" among investors regarding CoreWeave's financial strategy and execution capability. The company's mounting debt—projected by Morgan Stanley to reach $38 billion by end-2026—has been a key concern.

However, credit analysts point to CoreWeave's substantial contracted revenue backlog as a counterbalance. Moody's reported a backlog of $55.6 billion at the end of the third quarter of 2025. Steven McDonald, a director at S&P Global Ratings, stated that successful execution could lead to a credit rating upgrade from its current B+ rating, lowering future borrowing costs.

"They've kind of outperformed at a high level," McDonald said, noting CoreWeave "is carving out a role as a player in the AI data centre space. The relationship with Nvidia seems like it's going well, if not strengthening."

CoreWeave is scheduled to announce its fourth-quarter 2025 earnings, with the rate of its infrastructure spending and capacity growth being closely watched metrics for its ambitious scaling plans.
