Nvidia’s massive AI infrastructure commitment is creating potential opportunities across US and Japanese stocks — from AI chips and power infrastructure to the specialised equipment needed to manufacture them.
Nvidia’s latest infrastructure commitment is putting a spotlight on a much bigger investment theme: the companies supplying the chips, power, cooling and semiconductor equipment behind the global AI build-out.
The Deal in Brief
On August 17, 2026, Nvidia announced that it would guarantee up to US$105 billion in costs associated with a massive new data-centre campus in Ohio, which will be leased by OpenAI.
The PORTS-Pike Technology Campus in Pike County, Ohio, is being developed by SB Energy, backed by Japan’s SoftBank Group. OpenAI has signed a 20-year lease as the site’s sole tenant, while Nvidia will serve as the exclusive AI-compute supplier and financial guarantor. Nvidia is also committing a separate US$1.5 billion directly to SB Energy.
The campus is planned for approximately 8 gigawatts of computing capacity, potentially requiring around 1.5 million Nvidia GPUs. Supporting that computing load will require massive new power-generation and grid infrastructure, with the first operational phase targeted for 2028.
For investors, however, the bigger question is:
Who Actually Benefits?
The answer goes well beyond Nvidia.
The Deal in Brief
The PORTS-Pike Technology Campus is designed to become a major AI computing hub in Ohio.
OpenAI has signed a 20-year lease as the sole tenant, while SB Energy will develop and operate the site. Nvidia will supply the AI computing infrastructure and provide financial guarantees supporting defined portions of the project’s lease and power costs.
The scale is significant:
| Key Figure | Details |
|---|---|
| US$105 billion | Nvidia’s maximum guarantee commitment |
| US$1.5 billion | Nvidia’s separate investment in SB Energy |
| 8 gigawatts | Planned computing capacity |
| ~1.5 million | Potential Nvidia GPUs deployed |
| 2028 | Targeted start of initial operations |
| 20 years | OpenAI lease term |
The project highlights a fundamental reality of the AI boom: building AI capacity requires far more than semiconductors.
It requires electricity, power-generation equipment, cooling systems, data-centre infrastructure and an increasingly sophisticated semiconductor supply chain.
The “Circular Financing” Debate
The structure of the transaction has attracted attention on Wall Street.
Some investors have described the arrangement as a form of “circular financing”, in which a supplier effectively helps finance the infrastructure required for its own products.
Nvidia CEO Jensen Huang has pushed back on that interpretation, explaining that Nvidia is backing defined portions of the lease and power costs rather than funding the entire project, while OpenAI remains responsible for its rent obligations.
The debate is nevertheless worth watching because Nvidia’s relationship with OpenAI extends far beyond this single project. Nvidia has projected that its total OpenAI-related business could reach US$600 billion by 2030.
For investors, that raises an important question: How much of Nvidia’s future growth will come from genuine end-user demand, and how much will depend on increasingly complex financing and infrastructure arrangements?
Part One: The Companies Directly Connected to the Ohio Project
Several publicly traded companies have confirmed roles in the development of the Ohio campus.
| Company | Ticker | Role in Ohio Project |
|---|---|---|
| Nvidia | NASDAQ: NVDA | Exclusive AI chip supplier and financial guarantor |
| SoftBank Group | TSE: 9984 | Parent of SB Energy, the project developer and landlord |
| American Electric Power | NASDAQ: AEP | Grid upgrade partner via AEP Ohio |
| GE Vernova | NYSE: GEV | Gas turbine supplier for the project’s power plant |
| Carrier Global | NYSE: CARR | Cooling equipment supplier for the power infrastructure |
Two additional companies — Bechtel and Kiewit — are involved in the project’s construction. However, both are privately held, so investors cannot obtain direct stock-market exposure to their involvement.
There is also an important distinction between supplier commitments.
GE Vernova’s turbine involvement has been explicitly confirmed by an SB Energy spokesperson, while Carrier’s role has been reported as part of a broader US-Japan investment tranche. Investors should therefore distinguish between confirmed project contracts and broader supplier exposure.
Part Two: The Nvidia Semiconductor Supply Chain
The investment opportunity does not stop at companies directly involved in Ohio.
Nvidia designs its own AI processors but relies on a highly specialised global manufacturing ecosystem to produce them.
That means companies involved in semiconductor fabrication, testing, inspection, materials and advanced packaging can potentially benefit when Nvidia’s overall chip production increases — even if they have no direct contractual relationship with the Ohio project.
This distinction is important.
The companies below should therefore be viewed as broader AI semiconductor beneficiaries, not direct Ohio project participants.
| Company | Ticker | Semiconductor Exposure |
|---|---|---|
| Tokyo Electron | TSE: 8035 | Semiconductor manufacturing equipment for advanced chip production |
| Advantest | TSE: 6857 | Testing equipment for advanced AI chips |
| Disco Corporation | TSE: 6146 | Equipment used to cut and thin semiconductor wafers and HBM |
| Lasertec | TSE: 6920 | Advanced semiconductor inspection equipment |
| Shin-Etsu Chemical | TSE: 4063 | Silicon wafers and other semiconductor materials |
| Ibiden | TSE: 4062 | High-end semiconductor packaging substrates |
Tokyo Electron — TSE: 8035
Tokyo Electron is one of the world’s leading semiconductor manufacturing equipment suppliers.
As chipmakers move toward increasingly advanced manufacturing processes, demand for specialised equipment can rise alongside the expansion of leading-edge semiconductor capacity.
Advantest — TSE: 6857
Advantest is a major global supplier of semiconductor test equipment.
AI processors are becoming increasingly sophisticated and expensive, making comprehensive testing an essential part of the manufacturing process.
Disco Corporation — TSE: 6146
Disco specialises in equipment used for semiconductor manufacturing processes such as wafer cutting and thinning.
Its exposure is therefore tied to the broader expansion of advanced semiconductor production, including AI-related chips and high-bandwidth memory.
Lasertec — TSE: 6920
Lasertec is a major supplier of semiconductor inspection equipment, particularly for advanced lithography processes.
Its position gives investors exposure to the increasing complexity of leading-edge semiconductor manufacturing, although competitive developments remain an important factor to monitor.
Shin-Etsu Chemical — TSE: 4063
Before a chip can be manufactured, it needs a semiconductor wafer.
Shin-Etsu Chemical is one of the world’s major suppliers of silicon wafers and other semiconductor materials, giving it exposure to the underlying growth of chip production.
Ibiden — TSE: 4062
Ibiden is a major supplier of advanced semiconductor packaging substrates.
As AI processors become larger and more complex, advanced packaging is becoming increasingly important to semiconductor performance — making packaging companies another potential beneficiary of the AI infrastructure boom.
The Bigger AI Investment Chain
The Ohio project illustrates how the AI boom is expanding across multiple layers of the economy.
| Investment Layer | Examples | What Investors Are Watching |
|---|---|---|
| AI Compute | Nvidia | AI chip demand and data-centre deployment |
| Semiconductor Equipment | Tokyo Electron, Advantest, Disco, Lasertec | Growth in advanced chip manufacturing |
| Materials & Packaging | Shin-Etsu Chemical, Ibiden | Increasing chip complexity and production volumes |
| Power & Infrastructure | GE Vernova, AEP, Carrier | Electricity, cooling and grid capacity |
This creates a broader investment landscape than simply looking at the biggest AI chipmakers.
The AI infrastructure build-out is increasingly creating demand for everything surrounding the chip.
Why Japan Matters in the AI Trade
For investors, one of the most interesting aspects of the Ohio project is its connection to Japan.
SoftBank is a major Japanese technology and investment group, while several of the world’s most important semiconductor equipment and materials companies are also listed in Japan.
This means Japanese equities can provide a different route into the AI theme.
Rather than investing directly in AI chip designers, investors can gain exposure to the companies supplying the tools, materials, testing systems and packaging technologies needed to manufacture increasingly sophisticated processors.
In other words:
US markets offer exposure to the AI compute and infrastructure build-out.
Japan offers exposure to the semiconductor manufacturing ecosystem behind that compute.
From One Ohio Data Centre to a Global AI Theme
The Nvidia-OpenAI project is much more than a single data-centre development.
It demonstrates how the AI investment cycle is expanding into three interconnected areas:
AI COMPUTE
Nvidia and other chip designers
↓
SEMICONDUCTOR SUPPLY CHAIN
Tokyo Electron, Advantest, Disco, Lasertec, Shin-Etsu Chemical and Ibiden
↓
AI INFRASTRUCTURE
Power generation, grid upgrades, cooling and data centres
The key takeaway for investors is that AI is no longer just a semiconductor story.
It is increasingly an infrastructure story.
Every additional AI data centre requires more processors. Those processors require advanced semiconductor manufacturing. Semiconductor manufacturing requires specialised equipment, materials and testing. And all of it ultimately requires enormous amounts of electricity and cooling.
What Could Go Wrong?
The scale of the AI build-out also creates risks.
Massive capital requirements could put pressure on companies and customers if AI infrastructure spending slows. Financing structures could attract greater scrutiny, while power constraints could delay data-centre projects.
Investors should also consider valuation risk. Companies exposed to the AI theme have already attracted substantial market expectations, meaning even strong business growth may not always translate into higher share prices if expectations are already priced in.
There is also a competitive dimension.
Some semiconductor equipment markets are highly concentrated, but competition can evolve quickly as technology changes. Investors should therefore assess each company’s competitive position, earnings outlook and valuation rather than treating every AI-related stock as an automatic winner.
US or Japan: Where Is the AI Opportunity?
The Nvidia-OpenAI Ohio project provides a useful reminder that investors do not necessarily have to choose between US technology stocks and Japanese semiconductor companies.
They represent different parts of the same investment ecosystem.
From Nvidia’s AI processors and GE Vernova’s power equipment in the US to Tokyo Electron, Advantest, Disco and other Japanese semiconductor specialists, the AI build-out is creating opportunities across markets.
For investors looking to diversify their exposure to the AI theme, US and Japanese stocks offer different ways to participate in the next phase of AI infrastructure growth.
