Nvidia now guarantees the rent
The creditworthiness of the AI buildout increasingly rests on one chipmaker's balance sheet rather than on the tenants actually using the buildings.
Nvidia has agreed to guarantee up to $105bn of OpenAI's lease payments on a data-centre campus being built by SB Energy in Pike County, Ohio, and to invest $1.5bn in SB Energy itself. OpenAI has contracted for roughly 8 gigawatts of capacity at the site, the first 800 megawatts due in 2028. One gigawatt powers as many as 750,000 US homes. The $105bn covers only the first 4.25GW phase; Nvidia may take on more for the second (Bloomberg). Here is the plumbing. Whoever lends against that campus is not underwriting OpenAI, a five-year-old company with enormous revenue growth and enormous cash burn. They are underwriting Nvidia, the most valuable company in the world. The guarantee is what converts an unrateable tenant's rent into something a bond fund can buy. That is the whole trick, and it is the same trick as the Microsoft-linked QTS bond and the $500bn of compute-financing platforms Nvidia has agreed with Apollo, Blackstone, KKR, BlackRock, Brookfield and Goldman, where Jensen Huang has said Nvidia could backstop up to $125bn. What has to stay true: OpenAI keeps paying. If it doesn't, Nvidia writes cheques for twenty years on buildings full of its own chips. Nvidia says this is not circular financing. What we do not know is how the guarantee is accounted for — whether it is recognised at fair value as a financial guarantee or disclosed in a footnote, and what triggers a draw. Until that is in a filing, the largest single credit enhancement in the AI buildout is a press release. Nvidia shares fell 2.5% on the day.
