Nvidia Eyes $3 Billion Equity Stake in SB Energy, Extending Its Ohio Bet Beyond GPUs

From Guaranteeing Debt to Owning the Power

For months, Nvidia’s role in OpenAI’s colossal Ohio data center project has been that of a financial backstop — the deep-pocketed guarantor standing behind hundreds of billions in lease obligations. On Saturday, August 15, 2026, The Information reported a significant escalation: Nvidia is in talks to invest as much as $3 billion directly into SB Energy, the SoftBank-controlled subsidiary that is developing the massive planned data center campus in southern Ohio for OpenAI.

Reuters and CNBC picked up the report within hours, citing people familiar with the discussions. If completed, the deal would transform Nvidia from a creditor of convenience into a direct equity holder in the energy infrastructure underpinning one of the largest AI buildouts ever attempted — a structural shift with implications far beyond a single $3 billion check.

What We Know About the Deal

According to the report, Nvidia’s equity investment would serve a specific purpose: helping SB Energy raise debt for the 10-gigawatt project, which could ultimately cost more than $500 billion including chips. An equity infusion from the world’s most valuable semiconductor company would strengthen SB Energy’s balance sheet, making lenders more comfortable financing what is arguably the most ambitious energy-and-computing project in history.

The contours of the broader arrangement have been taking shape all summer:

• The project: A 10-gigawatt data center campus in Piketon, Ohio, on the site of the former Portsmouth Gaseous Diffusion Plant — federal land in Pike County repurposed for the AI era. SB Energy plans roughly 10 GW of new generation alongside the compute campus, including at least 9.2 GW of natural gas capacity, backed by a $33 billion gas plant plan.
• The lease: OpenAI has been negotiating a 20-year lease that would represent its single largest infrastructure commitment to date.
• The backstop: Nvidia has been in talks to guarantee a portion of the financing — a figure that reportedly started near $250 billion before being scaled back to roughly $100–120 billion covering the first phase, after investors flagged concerns about concentrated risk exposure.
• The equity: Now, on top of the guarantee, Nvidia would take a direct ownership position of up to $3 billion in SB Energy itself.

That last element is the news. A guarantee makes Nvidia a contingent creditor. An equity stake makes it a part-owner of the power company. Those are fundamentally different positions, with different rights, different economics, and different strategic implications.

Why Nvidia Would Want to Own Part of the Power Company

The logic of vertical integration in AI infrastructure is becoming impossible to ignore. The binding constraint on AI expansion in 2026 is no longer chip supply alone — it is electricity, land, permitting, and financing. Compute demand has outrun the ability of utilities and independent developers to deliver power on AI-lab timescales. Companies that control power have leverage; companies that don’t, wait.

For Nvidia, an equity stake in SB Energy addresses several exposures at once:

1. Securing gigawatt-scale power for its best customer. OpenAI is among Nvidia’s largest revenue sources, and its compute appetite is effectively unlimited for the next several years. If OpenAI’s buildout stalls because SB Energy cannot raise capital, Nvidia’s own revenue trajectory stalls with it. Owning a piece of the developer aligns incentives in a way contracts alone cannot.

2. Supporting the debt raise. The Information’s reporting is explicit that the investment is designed to help SB Energy raise debt. OpenAI lacks an investment-grade credit rating, which makes lenders hesitant regardless of nominal lease commitments. Nvidia’s earlier guarantee was meant to solve this by letting SB Energy borrow against Nvidia’s creditworthiness. An equity cushion of $3 billion does the same thing through the balance sheet rather than the guarantee — and unlike the guarantee, it is capital that has already been committed rather than a contingent promise.

3. Diversifying beyond silicon. Nvidia’s investments in OpenAI ($100 billion announced last October), Anthropic ($10 billion), and a growing web of AI startups have all been aimed at sustaining demand for GPUs. An energy investment extends the same logic one layer down the stack: if the bottleneck is power, own power. It mirrors moves by Microsoft, Google, and Amazon into nuclear power agreements and dedicated generation assets — but Nvidia is doing it as a supplier, not primarily as an operator.

4. Hedging the scaled-back guarantee. Reports earlier this week indicated Nvidia trimmed its planned backstop from ~$250 billion to under $120 billion after investor pushback. An equity stake lets Nvidia keep meaningful skin in the game at a known, capped cost — $3 billion of real capital instead of a nine-figure contingent liability that spooked shareholders. It is, in effect, a cheaper way to buy credibility for the project’s financing.

The SoftBank Dimension

SB Energy is controlled by SoftBank Group, which has been Masayoshi Son’s vehicle for renewable and now AI-adjacent power generation. SoftBank has already committed $500 million of its own to SB Energy alongside OpenAI’s matching investment earlier this year, part of the Stargate-adjacent buildout. Nvidia taking a stake in a SoftBank subsidiary deepens an already multi-layered relationship — SoftBank was an anchor in Nvidia’s $100 billion OpenAI investment circle, and Nvidia GPUs will presumably fill the Piketon campus.

The $3 billion figure is also notable relative to SB Energy’s capital base. This is not a token strategic investment; at that scale Nvidia would likely become one of the largest minority shareholders in the company, with board-level visibility into the most important power project in the AI economy.

What This Signals for the Industry

The most important reading of this news is structural: the AI supply chain is consolidating into the energy sector. For two years the industry debate centered on whether Nvidia’s circular financing arrangements — investing in customers who buy its chips — were sustainable. The Ohio saga shows the next phase: chipmakers underwriting and now owning the physical infrastructure of generation itself.

There are precedents for this pattern. Amazon bought a nuclear-powered data center campus in Pennsylvania. Google and Microsoft have signed offtake deals for advanced nuclear reactors. But Nvidia is a component supplier moving into an ownership position in its customers’ critical infrastructure — closer to Intel’s old playbook of investing across the ecosystem, executed at a speed and scale the semiconductor industry has never seen.

It also raises real governance questions. Nvidia would simultaneously be: the chip supplier to the campus, a guarantor of its financing, and an owner of its developer — while OpenAI, the tenant, buys chips from Nvidia using capital Nvidia itself invested. Each layer is defensible in isolation. Stacked together, they form a web of aligned incentives in which enormous amounts of risk and reward flow through a single company. Regulators and credit markets will be watching how the final structure is disclosed.

What Happens Next

Talks are ongoing and could still fall apart — the phrase “in talks” carries its usual weight. But the direction is clear. A deal announcement could come quickly; earlier reports suggested the broader Ohio financing arrangement was close to being finalized “as early as this weekend.”

For the AI industry, the significance is straightforward: the race for frontier compute has become a race for gigawatts, and the companies best positioned to win it are those willing to own the electrons, not just the silicon. Nvidia’s potential $3 billion stake in SB Energy is the latest — and one of the clearest — signals that AI’s capital cycle has moved decisively from models and chips into concrete, turbines, and debt.

The $500 billion question hanging over Piketon, Ohio is no longer whether the money will arrive. It is who will own the future it builds.
