Background
<cite index="3-2">The *Wall Street Journal* reported on July 26, 2026 that Nvidia is negotiating a financing guarantee of roughly $250 billion to help OpenAI secure its planned 10-gigawatt (GW) artificial intelligence campus in Piketon, Ohio.</cite> <cite index="3-3">Bloomberg and Reuters confirmed the report the same weekend.</cite> Neither Nvidia nor OpenAI had issued official statements as of publication; <cite index="9-10">Reuters noted it could not immediately verify the report, and Nvidia, OpenAI, and the U.S. Commerce Department did not respond to requests for comment.</cite>
The Site
<cite index="11-4,11-5">The data center would sit on federal land at the former Portsmouth Gaseous Diffusion Plant in Pike County, Ohio. In March 2026, the U.S. Department of Energy announced a partnership with SoftBank Group and its subsidiary SB Energy to redevelop the site, with SB Energy committing to build 10 GW of new power generation capacity, including at least 9.2 GW from natural gas.</cite> <cite index="8-7">Commerce Secretary Howard Lutnick, SoftBank founder Masayoshi Son, and Energy Secretary Chris Wright broke ground on the complex in March.</cite> <cite index="5-8">The electricity supply is reportedly controlled by the U.S. government and separately funded by Japan under a recent trade agreement linked to Tokyo's commitment to invest $33 billion in a natural gas facility.</cite>
The Piketon campus would represent a separate, single-site expansion beyond the existing Stargate program. <cite index="13-4,13-5">OpenAI, Oracle, and SoftBank launched Stargate — OpenAI's overarching artificial intelligence infrastructure platform — across five new U.S. data center sites; combined with the flagship site in Abilene, Texas, and ongoing projects with CoreWeave, Stargate reached nearly 7 GW of planned capacity and over $400 billion in investment over the next three years.</cite>
The Financing Structure
<cite index="3-4">What the reports call a "guarantee" is a specific financial instrument: if OpenAI fails to make lease payments or service the construction debt on the Piketon campus, Nvidia steps in and covers the obligation.</cite> <cite index="7-4">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.</cite>
<cite index="9-6,9-7">The $250 billion figure applies to the data center lease and construction debt, not to the Nvidia Graphics Processing Unit (GPU) chips that will fill the building — those are the subject of a separate discussion, with the *Journal* reporting chip purchase financing that could reach a further $350 billion.</cite> <cite index="4-4">The total cost, including chips, could exceed $500 billion, making it the largest data center project announced to date.</cite>
<cite index="1-7">The first phase of the Ohio project is expected to deliver approximately 800 megawatts of capacity and is currently scheduled for completion in 2028.</cite>
Strategic Rationale
<cite index="2-4">For OpenAI, a deal would be the first step toward controlling its own infrastructure instead of renting it from Microsoft, Amazon, and Oracle, while for Nvidia, it would guarantee demand for its chips for years to come.</cite>
<cite index="22-2,22-3">OpenAI reached $25 billion in annualized revenue (Annual Recurring Revenue) by the end of February 2026, up 17% from $21.4 billion at the end of 2025, but remains deeply unprofitable with a -122% non-GAAP operating margin in Q1 2026.</cite> <cite index="20-3">On March 31, 2026, OpenAI closed a $122 billion funding round at an $852 billion post-money valuation, co-led by SoftBank alongside Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price-advised accounts.</cite>
<cite index="8-4">Nvidia has already invested $30 billion in OpenAI.</cite> <cite index="11-1">In September 2025, Nvidia and OpenAI signed a letter of intent for at least 10 GW of Nvidia systems, with Nvidia committing up to $100 billion in OpenAI as capacity comes online.</cite>
Market Reaction and Caveats
<cite index="5-2,5-3">Shares of CoreWeave and Nebius Group moved higher after the report: CoreWeave advanced 4% while Nebius climbed 6%.</cite> <cite index="2-9">The deal underscores a broader shift as technology giants increasingly tap debt and equity markets to fund artificial intelligence infrastructure, with spending set to top $700 billion this year.</cite>
<cite index="1-8,1-9">Negotiations are still underway and the terms of the agreement have yet to be finalized; there is no certainty that the proposed financing package will ultimately be completed.</cite>
