Nvidia's guarantees to AI clouds are the real risk in Huang's exit: up to $108.5 billion in leases

The headline risk in Jensen Huang's exit is not the chips. It is the paper Nvidia has signed. Over the past year the company has guaranteed leases, promised to buy unused computing capacity and lent its name to a $500 billion financing plan, and those promises are what let heavily indebted AI cloud companies borrow at lower rates. With Huang gone and Colette Kress running Nvidia as interim CEO, lenders are asking how firm that backing is. Our report on the 8-K has the resignation itself.

What Nvidia has promised

Bisnow's Thursday breakdown of Nvidia's data center footprint lists the main commitments. Nvidia has guaranteed up to $108.5 billion of data center leases if certain tenants cannot pay. About $3.5 billion of that backs smaller AI cloud companies; the rest, up to $105 billion, backs a planned OpenAI campus at SB Energy's Ohio site. Bisnow reports OpenAI has agreed to repay Nvidia for anything it covers, and that the first buildings are not due until 2028. It also reports Nvidia has agreed to buy up to $6.3 billion of computing capacity CoreWeave cannot sell, through April 2032.

Fortune adds the financing layer: a July offer to rent back unused GPU capacity from neocloud partners at a fixed rate, meant to make banks more willing to lend, and a $500 billion platform with six institutional partners, of which Nvidia may backstop up to $125 billion. CNBC notes those August agreements are memorandums of understanding, still preliminary and subject to final agreements.

Why a guarantee changes the interest rate

Joe Kaiser, who runs Switchyard Partners and backs AI infrastructure, told Fortune the chip is not what puts these companies at risk; the financial backstop is what lets them raise debt. His words: "If the capital providers now say that Nvidia guarantee is not worth what it was worth a week ago, that puts those neocloud businesses at risk." That is one investor's view, not a measured fact, but the mechanism is simple. A lender who is repaid by Nvidia if a tenant fails prices the loan off Nvidia's credit, not the tenant's.

The market has been testing that credit already. Bisnow, citing Bloomberg, reports the cost of insuring Nvidia's debt against default has roughly tripled since midsummer and hit a near-record Thursday, though it remains about half what investors pay to insure Oracle's. That is a sign the market still sees Nvidia as a strong borrower, and also a sign guarantees are no longer free.

What lenders are saying

Sunaina Sinha Haldea of Raymond James told CNBC she does not think the capital walks away, because lenders are underwriting the chips and the customer contracts behind them, "but they could want to be paid more for the uncertainty." Saxo's Charu Chanana called it "not a financing crisis yet." Both described the risk as slower commitments or tighter terms, not a collapse.

Bisnow also quotes market analyst Ted Mortonson saying Nvidia's commitments will now be treated as potential liabilities, and reports Kress disagreed with Huang over some of Nvidia's riskiest bets. Treat that as reporting about internal views, not a policy announcement. Nvidia has not changed any guarantee.

The stocks that reacted

Using Yahoo Finance closes, CoreWeave fell to $56.60 on Thursday from $60.77, down 6.9% (our calculation), giving back part of Wednesday's 24% jump that we covered. Nebius closed at $128.64, down 16.8% from $154.69, but it also cut its outlook the same day, as we reported, so not all of that is about Huang. Nvidia itself closed at $166.19, down 4.3%.

Who this reaches

• AI cloud borrowers: if lenders add even a little spread to Nvidia-backed loans, the cost lands on companies already carrying heavy debt. See our look at CoreWeave's bond yields.
• Data center developers and landlords: projects that borrowed against an Nvidia-backed lease need that lease to hold its value in the lender's eyes. The ones to watch are those leased to smaller AI clouds, the $3.5 billion slice.
• Regional contractors and utilities: new builds that depend on that financing could be delayed if terms tighten. That is a possibility analysts raise, not something that has happened.

What to watch

Nvidia reports quarterly results Tuesday, November 17. Kress's tone on the guarantees, the $500 billion agreements and the search for a permanent CEO will tell lenders more than any analyst note. Also watch whether the financing partners sign final agreements or ask for changes.
