Nvidia is putting more money behind the physical infrastructure needed for large AI systems. The company said on Monday that it will invest $1.5 billion in SB Energy, a data center and power developer connected to SoftBank and OpenAI.
The investment is not only about equity. It also strengthens Nvidia’s role in OpenAI’s Ports-Pike data center near Cincinnati, Ohio, where the company is set to become the sole supplier of compute infrastructure.
A deal built around compute supply
The most direct effect of the investment is control over the compute layer. According to documents Nvidia filed with the SEC, the arrangement ensures that Nvidia will be the sole supplier of compute infrastructure at OpenAI’s Ports-Pike data center.
That matters because the project is large even at its starting point. The facility could scale from an initial 4.25 gigawatts to 8 gigawatts in size, according to those documents. For an AI data center, that scale makes the supply of compute hardware and supporting infrastructure central to the entire project.
Nvidia is also expected to provide up to $105 billion in credit to help build the facility. That figure shows how the economics of AI infrastructure are extending beyond chip sales into financing, site development and long-term capacity planning.
For Nvidia, the arrangement places its technology at the center of a major OpenAI-linked buildout. For SB Energy, it brings capital and a committed compute supplier into a project that depends on both machines and power.
SoftBank, OpenAI and SB Energy are already linked
SB Energy’s existing investors include SoftBank and OpenAI. The company is therefore not a neutral outside contractor in the project, but part of a broader network of AI infrastructure investment.
SoftBank’s role is especially notable because it previously held $5.8 billion worth of Nvidia stock. It sold that stock in November to help fund other AI investments.
The Nvidia investment now adds another layer to that relationship. A company whose stock SoftBank sold is investing in a developer connected to SoftBank and OpenAI, while also becoming the compute infrastructure supplier for the OpenAI data center.
The result is a tightly connected structure around one major AI infrastructure project:
- Nvidia is investing $1.5 billion in SB Energy.
- Nvidia will be the sole compute infrastructure supplier at the Ports-Pike data center.
- Nvidia may provide up to $105 billion in credit to support construction.
- SB Energy’s existing investors include SoftBank and OpenAI.
The power plant is as central as the data center
The Ports-Pike project is not only a data center story. SB Energy will build a 9.2 gigawatt natural gas power plant on the site, which is land owned by the U.S. Department of Energy.
The history of the site adds another layer of significance. The land previously enriched uranium for the U.S. nuclear arsenal and for U.S. Navy submarines. Now it is being positioned as part of the energy base for AI infrastructure.
The planned power plant is expected to cost $33 billion. That cost reflects a broader rise in natural gas power plant construction expenses, which have risen 66% in the last two years, according to BloombergNEF.
In plain terms, the project depends on solving two linked problems at once. The data center needs enough compute infrastructure to serve OpenAI’s workload, and it also needs enough power to support that infrastructure at scale.
Natural gas prices could become a constraint
The source of power introduces a wider market question. By the time SB Energy’s power plant and others are completed, they will be competing for natural gas with export markets.
That competition could triple natural gas prices in some parts of the country. If that happens, the cost of operating and supporting large AI data centers could become more exposed to energy market pressure.
This is why the Nvidia investment is bigger than a single corporate financing event. It shows how AI data centers are becoming tied to power generation, fuel markets and large-scale construction costs.
The deal also makes clear that the next phase of AI infrastructure is not limited to chips. It requires credit, land, power plants, supply agreements and developers capable of coordinating all of those pieces.
What the investment signals
Nvidia’s $1.5 billion investment in SB Energy gives the company a deeper role in the physical expansion of AI capacity. The Ports-Pike data center near Cincinnati, Ohio, is positioned around Nvidia compute infrastructure, OpenAI demand and a large natural gas power project.
The scale is the defining feature. A facility that could grow from 4.25 gigawatts to 8 gigawatts, supported by a 9.2 gigawatt natural gas power plant, requires decisions that reach well beyond server rooms.
The central question is no longer just who can supply the AI hardware. It is also who can finance, power and build the infrastructure around it.
