Shares of Nvidia (NASDAQ: NVDA) rose 0.5% in early Monday trading, building on an 11% gain over the past month, as investors digested details of the company's financial commitment to OpenAI's massive data-center project in Ohio.

The new details clarify both the scale and the limits of the chipmaker's involvement in one of the largest artificial-intelligence infrastructure buildouts announced to date. Nvidia, headquartered in Santa Clara, California, designs the graphics processors used to train and run large AI systems around the world.

A Trimmed Guarantee

The site, called the PORTS-Pike Technology Campus, is located in Ohio and ranks among the biggest AI infrastructure projects announced so far. It is the latest piece of a broader buildout: OpenAI formed the Stargate venture with SoftBank and Oracle in January 2025 with plans to invest up to $500 billion in US data centers, and other cloud and AI providers have announced multibillion-dollar campuses of their own. Nvidia confirmed it will provide a financial guarantee for the project, though the amount has been trimmed.

The guarantee was originally reported at $250 billion. It has since been reduced to less than $120 billion, according to The Wall Street Journal, which cited people familiar with the matter. The change came after investors raised concerns about Nvidia's balance-sheet exposure.

Those concerns are rooted in the increasingly intertwined finances of the AI boom. Nvidia and OpenAI have been linked since September 2025, when Nvidia said it would invest up to $100 billion in the ChatGPT maker as OpenAI committed to deploying $100 billion of Nvidia systems.

Chief Executive Jensen Huang was clear about the limits of the company's support. “Our support is limited to defined portions of lease and power payments, along with a specified residual-value commitment, not the full cost of the site or all of the tenant's obligations,” he said.

Alongside the guarantee, Nvidia said it will invest $1.5 billion in SB Energy, the infrastructure company set up by OpenAI and SoftBank Group, the Japanese technology investment conglomerate, to build, own, and operate the data center. OpenAI, the San Francisco-based developer of ChatGPT, will lease the site for 20 years.

What the Numbers Look Like

Each generation of AI systems deployed at PORTS-Pike could require around 1.5 million Nvidia GPUs. That volume translates to between $150 billion and $200 billion in Nvidia revenue per upgrade cycle.

With multiple upgrade cycles possible over the course of the 20-year lease, Huang put the total opportunity in sharper focus. “At these levels, the opportunity represents roughly $600 billion of Nvidia compute through 2030,” he said, describing the cumulative compute tied to the project through the end of the decade.

OpenAI's existing and planned commitments currently sit at around 12 gigawatts of Nvidia compute. That figure could rise to around 16 gigawatts if Nvidia extends the PORTS-Pike arrangement beyond the initial 4.25 gigawatts outlined in the deal. Customer concentration is already a factor in Nvidia's results: two direct customers each accounted for more than 10% of the company's revenue in its most recent fiscal year, according to its annual filing.

Nvidia's Broader Investment Strategy

The deal fits into a wider pattern for Nvidia, one of the world's most valuable publicly traded companies. The company has made 66 private-company investments in 2025 and 2026, according to data provider FactSet. In November 2025, it agreed to invest up to $10 billion in Anthropic, the developer of the Claude chatbot, as part of a deal in which Anthropic committed to purchasing a gigawatt of Nvidia compute. Some investors have questioned whether that capital should instead be returned to shareholders, and some critics have likened Nvidia's arrangements to the vendor financing that strained telecom-equipment makers in the early 2000s, arguing that Nvidia's money effectively cycles back to it as chip orders.

More recently, Nvidia said it would partner with Wall Street firms to make $500 billion in capital available for customers to finance AI infrastructure. The company has also said it might provide a residual-value support mechanism in such deals, capped at 25% of any individual deal.

Stock Performance and Insider Activity

Nvidia's stock has risen 24% over the past 12 months. The company's trailing twelve-month price-to-earnings ratio — a measure comparing the share price with per-share profit over the past year — stands at 34.56x, well below its five-year median of 57.4x.

Insider activity over the past three months shows net selling, with $410.6 million in Nvidia stock sold by insiders and no insider buying recorded during that period.

Investors will be watching Nvidia's coming quarterly reports for further detail on how the PORTS-Pike guarantee and any residual-value commitments are reflected on the company's balance sheet.
