Nvidia in Talks to Guarantee $250B of OpenAI Data Center Debt (2026)
A financing guarantee is a promise by a third party to repay a debt if the borrower cannot. Nvidia is in talks to provide one for OpenAI, covering $250 billion of lease and debt on a new data center. A chip supplier would be underwriting the credit of the company buying its chips.
Why Nvidia Would Guarantee OpenAI Data Center Debt
The Wall Street Journal reported the talks on July 26, and Reuters and Bloomberg followed the same day. The site is in southern Ohio, developed by SoftBank's energy arm, and OpenAI has been in advanced lease talks for weeks. OpenAI runs today on rented Microsoft, Amazon and Oracle servers. Owning capacity ends that dependence, and Nvidia keeps a customer buying chips.
What the $250 Billion Guarantee Actually Covers
The guarantee applies to the data center lease and the debt behind it. Nvidia's own chips sit outside that figure. A separate $350 billion in chip-purchase financing is under discussion, and the full project tops $500 billion. The build is rated at 10 gigawatts, and phase one at 800 megawatts targets completion in 2028. Power for the site is controlled by the US government and funded separately by Japan.
Vendor Financing and What It Does to a Market
Vendor financing (a seller lending to or guaranteeing its own buyer) is not new. Telecom equipment makers used it heavily, pulling demand forward and, in some cycles, inflating it. When the seller underwrites the buyer, supply and demand circle inside a single balance sheet. Analysts expect capital access, not chip design, to become the real barrier to entry.
So How Does This Affect You?
For US investors, the read on an order book changes. Analysts note that bookings backed by a seller's own guarantee carry different risk from bookings paid in cash, and a buildout financed this way concentrates exposure in fewer names. With the Commerce Department controlling the power and Japan funding it, one Ohio site now sits inside US industrial strategy. Nothing is signed yet.
Key Takeaways
① $250B guarantee - Nvidia is in talks to back the lease and debt on an OpenAI data center.
② Chips excluded - The guarantee skips Nvidia's own chips; $350 billion in chip financing is separate.
③ Not signed - Nvidia, OpenAI and the Commerce Department did not comment.
