Nvidia is deepening its involvement in OpenAI’s artificial-intelligence infrastructure expansion through SB Energy and a huge planned data center campus in Pike County, Ohio. The latest structure includes a $1.5 billion Nvidia investment in SB Energy, alongside financial guarantees connected with the first phase of the project.
The development is important for NVDA investors because Nvidia’s role increasingly extends beyond selling GPUs. The company is helping finance infrastructure that could eventually become a major customer for its AI accelerators, networking equipment and computing systems.
Nvidia’s SB Energy investment takes shape
Earlier discussions indicated Nvidia could invest as much as $3 billion in SB Energy, potentially split between an initial investment and another commitment linked to a future initial public offering.
The current structure centers on an initial $1.5 billion equity investment. SB Energy has separately been preparing for a potential IPO, although its timing, valuation and fundraising target could still change.
The equity investment is different from Nvidia’s much larger financial support for the Ohio campus. Nvidia could provide guarantees of roughly $105 billion for the initial development, significantly below the approximately $250 billion structure previously discussed.
The revised arrangement could reduce Nvidia’s early financial exposure while still helping the project secure the enormous amount of capital required for construction.
OpenAI signs long-term Ohio data center agreement
OpenAI, the company behind ChatGPT, has agreed to lease computing capacity at the PORTS-Pike Technology Campus. SB Energy is responsible for developing and operating the infrastructure at the former Portsmouth Gaseous Diffusion Plant site in Pike County, southern Ohio.
The broader development could eventually support as much as 10 gigawatts of data center capacity. Initial capacity is expected to arrive in phases rather than bringing the entire campus online at once.
Building infrastructure on that scale requires far more than servers. Developers need power plants, transmission lines, substations, cooling equipment and grid connections before AI computing systems can operate.
That infrastructure requirement has become increasingly important to Nvidia’s long-term AI data center growth as technology companies commit billions of dollars to expanding computing capacity.
Ohio project highlights AI’s enormous electricity demand
The U.S. Department of Energy outlined plans for 10 GW of new power generation to support a 10 GW data center development at the Portsmouth Site. The department said at least 9.2 GW of the proposed generation would come from natural gas.
SB Energy and AEP Ohio have also been associated with approximately $4.2 billion in transmission investment, including high-voltage lines and substations.
The scale highlights one of the biggest challenges facing the AI industry. Companies can buy advanced processors, but those chips cannot operate without sufficient electricity, cooling and data center infrastructure.
SB Energy already has close ties with OpenAI
SB Energy had an established relationship with OpenAI before the Ohio development. In January 2026, OpenAI and SoftBank Group each committed $500 million to SB Energy, providing $1 billion in combined investment.
OpenAI also selected SB Energy to build and operate a previously announced 1.2 GW data center in Milam County, Texas.
Those projects give Nvidia a strategic reason to participate. More completed AI campuses could create additional demand for Nvidia hardware as OpenAI and other developers expand computing capacity.

Why the deal matters for NVDA investors
Nvidia benefits when additional AI infrastructure becomes operational because new facilities can require large quantities of GPUs and networking technology. Helping remove financing constraints could therefore support future hardware demand.
However, financing infrastructure introduces risks that do not exist in a conventional chip sale. Nvidia could simultaneously become an investor, technology supplier and financial guarantor for projects using its products.
That relationship means shareholders need to consider both potential equipment revenue and Nvidia’s financial exposure if projects are delayed, reduced in size or face funding difficulties.
Similar concerns have previously influenced Nvidia stock as investors assessed its OpenAI-related financial commitments, showing why the structure of these agreements can matter alongside expected AI demand.
Understanding the different billion-dollar figures
The numbers surrounding the project describe separate financial arrangements rather than one enormous Nvidia payment.
Nvidia’s initial SB Energy equity investment is approximately $1.5 billion, while earlier discussions contemplated as much as $3 billion. The roughly $105 billion figure relates to potential financial guarantees supporting the initial Ohio development.
That is considerably below the approximately $250 billion guarantee previously discussed, suggesting the parties have moved toward a structure that limits Nvidia’s initial exposure.
The Ohio project ultimately represents a long-term infrastructure bet. If construction proceeds as planned and OpenAI’s computing requirements continue growing, Nvidia could benefit from additional demand for its technology. At the same time, investors will need to watch the size and terms of Nvidia’s financial commitments as AI infrastructure becomes a larger part of its growth strategy.
