OpenAI is in advanced talks to lease SB Energy's 10 GW data center campus in Piketon, Ohio, with Nvidia in discussions to guarantee roughly $250 billion of the financing behind it, the Wall Street Journal reported on Sunday, citing unnamed people familiar with the matter. The site would be OpenAI's first as a tenant rather than a customer of Microsoft, Amazon, or Oracle, and Nvidia is separately discussing financing the accelerators going inside, which could run to another $350 billion. Terms haven't been settled, and the arrangement could still collapse.
OpenAI has no investment-grade credit rating, and Nvidia's involvement would let SB Energy raise debt against Nvidia's balance sheet instead of its tenant's. Nvidia has already put $30 billion into OpenAI, which has raised its projected compute spending to around $750 billion through 2030, up from roughly $600 billion earlier this year, according to the Journal. Commerce Secretary Howard Lutnick controls allocation of the site's power, and Anthropic, Microsoft, and Google have all spoken to him about it in recent weeks.
Nvidia's Q1 FY2027 10-Q caps maximum gross exposure across all of its partner facility lease guarantees at $3.5 billion, shrinking as partners pay their lessors, with $712 million sitting in escrow against it. Nvidia took the guarantees in exchange for warrants and carries them as credit derivatives, describing their fair value as immaterial.
The first one, disclosed in the third quarter of fiscal 2026, was capped at $860 million with $470 million of escrow behind it. The partner separately contracted to sell the data center cloud capacity, and Nvidia retained the option to assume the lease for internal use or sublease it if the escrow and that contract came up short. Neither remedy has an obvious equivalent at a 10 GW campus on federal land.
Nvidia held $62.6 billion in cash, cash equivalents, and marketable securities when fiscal 2026 closed on January 25, against full-year revenue of $215.9 billion and net income of $117 billion. A $250 billion guarantee works out at roughly 71 times the guarantee book Nvidia has disclosed, more than a year of revenue, and about four times its cash.
SB Energy broke ground at the former Portsmouth Gaseous Diffusion Plant on March 20 alongside Energy Secretary Chris Wright, Lutnick, and SoftBank chairman Masayoshi Son. The site enriched uranium for the U.S. weapons program from 1954 until 2001 and is still being decontaminated. The Department of Energy had listed it among 16 federal sites opened to data center construction, and SB Energy leases the land rather than owning it. Powering the campus takes 9.2 GW of new natural gas generation plus $4.2 billion of transmission work with AEP Ohio, funded by $33.3 billion Japan committed under its trade agreement with the U.S. The first phase, roughly 800 MW, is expected in 2028.
OpenAI gave up on building its own data centers last year in favor of leasing capacity, and SoftBank carries more than $130 billion of debt while funding buildouts in Ohio, France, and elsewhere.
