Nvidia is reportedly in discussions to provide a staggering $250 billion in financial guarantees to help OpenAI lease a planned 10-gigawatt data center campus in southern Ohio. The project, which is being developed by SB Energy (a subsidiary of Japan's SoftBank Group), marks one of the most ambitious technological infrastructure initiatives in U.S. history. The total cost of the facility, including the high-performance AI processors required to power it, could eventually exceed $500 billion.

Since OpenAI does not currently possess an investment-grade credit rating, Nvidia's backstop would act as a crucial security mechanism to help the startup secure favorable debt financing. The $250 billion guarantee would specifically cover the data center lease and construction-related debt. Separately, Nvidia is also discussing up to $350 billion in financing to support OpenAI's direct purchase of its processing chips, showcasing a deeply intertwined partnership between the two industry leaders.

The Rise of Circular Financing in the AI Boom

Analysts have noted that this arrangement highlights a growing trend of "circular financing" within the artificial intelligence sector. In this loop, a dominant hardware supplier (Nvidia) helps finance the massive infrastructure projects that subsequently drive demand for its own processors. This strategy secures multi-year chip orders for Nvidia and enables OpenAI to scale its training capabilities to unprecedented levels, though some financial watchdogs warn it could create structural risks if AI revenues fail to match capital expenditure.

A Staggering Power Demand: The 10-Gigawatt Campus

The scale of a 10-gigawatt data center is difficult to overstate. To put it in perspective, 10 gigawatts is enough power to support roughly 7.5 million average American homes, or equivalent to the total electrical output of several nuclear power plants. The southern Ohio campus will be constructed in phases, with the first phase targeted for completion in 2028 to deliver 800 megawatts of power. This massive footprint reflects OpenAI's belief that training artificial general intelligence (AGI) will require compute resources far beyond what is currently available.

Part of a Broader Infrastructure Strategy

This potential Ohio project is separate from, though related to, broader AI infrastructure initiatives like the "Stargate" project, an ongoing collaboration involving OpenAI, SoftBank, Oracle, and MGX to deploy compute capacity across the United States. Although negotiations for the Ohio campus are in preliminary stages, it represents a bold shift for Nvidia from simple equity investing to securing its dominance in the AI hardware supply chain for decades to come.
