Nvidia Backs OpenAI Ohio Campus With SB Energy Deal

Nvidia said on August 17 that it will invest $1.5 billion in SB Energy and provide credit support for the first 4.25 IT-GW of an Ohio data-center campus that OpenAI plans to use under a 20-year lease.

The announcement turns the AI buildout into a financing story as much as a chip-supply story. Nvidia is not only selling compute into the project. It is helping secure the land, power and shell capacity needed before the chips can be installed.

What Nvidia committed

The Nvidia PORTS-Pike announcement says the company will be the exclusive AI compute infrastructure provider at the PORTS-Pike Technology Campus in Pike County, Ohio. SB Energy will build, own and operate the data center, while OpenAI will be the customer.

Nvidia said the initial deployment is designed for 4.25 IT-GW of AI factory capacity, with an option to take the remaining 3.75 IT-GW. The company also said it will provide credit support for land, power and shell buildout and invest $1.5 billion in SB Energy.

That distinction matters. The commitment is not described as Nvidia paying for every future OpenAI chip purchase or writing a simple $105 billion check. The scarce asset named in the filing and announcement is the physical shell around future compute: land, power access and data-center capacity.

OpenAI gets a long lease, not instant capacity

OpenAI's OpenAI PORTS-Pike project page says it entered an agreement to secure about 8 gigawatts-IT at the campus with SB Energy, Nvidia and the U.S. Department of Energy. The first 800 megawatts are expected in 2028, while the broader buildout runs through 2032.

The page also sets several boundaries. OpenAI says it will begin paying only as completed capacity becomes available for lease. Further development depends on infrastructure, permits, environmental reviews and financing. New power plants, including natural gas generation, and new transmission lines will be required beyond the first capacity block.

Those caveats make this closer to an infrastructure pipeline than a finished supply event. The useful question is whether OpenAI, Nvidia and SoftBank can convert a former Portsmouth gaseous diffusion site into staged, financed capacity without turning every missing power and permit step into a later delay.

The financing concern is now explicit

Nvidia's SEC 8-K filing repeats the core structure: Nvidia announced a partnership with SB Energy to advance the PORTS Technology Campus, with credit support tied to the Portsmouth site and land, power and shell capacity for Nvidia compute.

Independent coverage focused on the same tension. Axios reported that OpenAI is taking a long lease for a large Ohio data center with Nvidia backing and that the arrangement raises questions about circular AI infrastructure financing because suppliers, investors and customers are increasingly entangled.

That concern does not invalidate the project. It defines the risk investors now have to track. If Nvidia helps finance the infrastructure that makes OpenAI a larger Nvidia customer, future revenue may be real while the balance-sheet exposure is also real.

What comes next

The next hard evidence is not another headline about total gigawatts. It is whether the first 800 megawatts stay on schedule for 2028, whether SB Energy finances the initial 4.25 IT-GW block, and whether local power, environmental and transmission approvals arrive without pushing the six-year buildout.

This sits beside the broader AI infrastructure question raised in recent data-center stories, from Prologis' 5.8 GW power pipeline to Alphabet's AI capex and cash-flow test. Capacity is becoming a financial instrument before it becomes a live server hall.

For now, the new fact is specific: Nvidia has tied equity, credit support and exclusive compute supply to an Ohio campus where OpenAI wants 8 IT-GW over time. The open question is whether that structure proves the AI boom can finance its own physical bottlenecks.
