On Sunday, the Wall Street Journal reported that Nvidia is in talks to guarantee approximately $250 billion in financing for OpenAI. The money would let OpenAI lease a 10-gigawatt data center that SoftBank's energy subsidiary is building on the site of a former Cold War uranium enrichment facility in Piketon, Ohio. The guarantee covers the lease and construction debt. The chips that go inside cost an additional $350 billion. Total project cost exceeds $500 billion.
The guarantee is necessary because OpenAI cannot secure conventional financing. The company is projected to lose approximately $14 billion this year on roughly $25 billion in revenue. It does not hold an investment-grade credit rating. Long-term construction financing at this scale requires a balance sheet that OpenAI does not have. Nvidia is volunteering its own.
## The Structure
Vendor financing describes an arrangement where the supplier of a product guarantees the customer's ability to purchase it. Nvidia guarantees the lease. OpenAI fills the facility with Nvidia GPUs. The guarantee and the purchase order are the same transaction described from two directions.
Nvidia reported $81.6 billion in revenue last quarter and holds $13.2 billion in cash. A $250 billion guarantee against $13.2 billion in cash is a ratio of nineteen to one. But the guarantee is also a chip order. If the facility gets built, it gets filled with $350 billion in Nvidia hardware. Those purchases become the revenue that supports the balance sheet that underwrites the guarantee.
## The Exposure
This is not an isolated arrangement. Nvidia holds a $30 billion equity stake in OpenAI. It backstopped $6.3 billion for CoreWeave. It invested $2 billion in xAI. It signed a deal with SK Group exceeding $500 billion. Bloomberg reported that Nvidia has announced over $540 billion in similar arrangements this year alone, excluding the OpenAI discussions. Google has made a parallel move, backstopping $35 billion in lease payments for Anthropic data centers.
At its peak in 2000, Lucent Technologies committed $8.1 billion in vendor financing to telecom carriers, 24 percent of its $33.6 billion in revenue. When those carriers failed, Lucent wrote off $3.5 billion and revenue fell from $33 billion to $12 billion in two years. Nvidia's proposed OpenAI guarantee alone represents 116 percent of its $215.9 billion in annual revenue.
## The Defense
Jensen Huang dismisses the comparison. His investments represent a small percentage of customer fundraising needs, he has said. Lucent's customers were cash-burning competitive carriers with no revenue base. Nvidia's four largest customers generated $451 billion in combined operating cash flow in 2024. The defense has real merit where it applies. But OpenAI is not Microsoft. OpenAI is the customer that cannot finance this project on the strength of its own operations. The guarantee exists because the debt market already evaluated the borrower and declined.
## The Site
The PORTS Technology Campus operated as a uranium enrichment facility from 1954 to 2001, processing uranium hexafluoride through thousands of barrier tubes to concentrate fissile U-235 from inert U-238. The process did not create fissile material. It concentrated what was already present into a usable form.
The financial structure Nvidia is proposing runs the same process on a different element. OpenAI has demand for computing infrastructure but not the creditworthiness to lease it. Nvidia concentrates its own balance sheet into a form that makes OpenAI bankable, using revenue that OpenAI generates by purchasing Nvidia's product. The enrichment cycle is closed: the cosigner's ability to guarantee comes from the revenue that the guarantee creates.
When you cosign a friend's lease, you tell the landlord you believe they will pay. When the cosigner is also the vendor who profits from the guaranteed purchase, the signature carries a different meaning. The credit market evaluated this borrower and said no. Nvidia is overriding that verdict because Nvidia's revenue depends on the loan going through. A cosigner who profits from the approval is providing capital, structured as confidence.
