NEW YORK – When a company guarantees a quarter-trillion dollars of its own customer’s lease obligations, it has stopped being a supplier and become something that has no clean precedent in the technology industry.
Nvidia is in early talks with OpenAI to guarantee as much as $250 billion in financing that would allow the AI lab to lease computing capacity from a SoftBank-owned megaproject in southern Ohio, the Wall Street Journal reported Sunday. The arrangement, as described by sources familiar with the negotiations, would make the world’s most valuable chipmaker the financial backstop for the lab that spent more than $30 billion in Nvidia hardware in its last fiscal year.
The Ohio campus has been gathering scale for over a year. SoftBank is developing a 10-gigawatt computing facility with a total cost above $500 billion, requiring electrical generation equivalent to roughly ten large nuclear reactors running simultaneously. OpenAI is in talks to become its anchor tenant, with the first 800-megawatt phase targeted for 2028. Anthropic, Google, and Microsoft have each shown interest in leasing portions of the site as well.
The $250 billion figure marks a discrete new development. Eastern Herald reported in June that OpenAI and Nvidia were discussing the Ohio campus and Nvidia’s role in helping to finance it, but no dollar amount had emerged from those early talks. Sunday’s Wall Street Journal report attaches a specific figure to the arrangement for the first time and frames it as a guarantee: Nvidia would backstop OpenAI’s lease obligations rather than write checks to SoftBank directly.
A separate negotiation covering chip purchases worth up to $350 billion is also underway, the Journal reported, bringing the total scope of Nvidia’s potential financial entanglement with OpenAI to a figure that would have been unthinkable for a hardware company eighteen months ago. Nvidia has already invested $30 billion directly in OpenAI, and OpenAI raised its own infrastructure spending forecast from $600 billion to $750 billion through 2030 earlier this year.
The structure’s circularity is what investors and regulators are now tracking. Nvidia sells chips to OpenAI. OpenAI leases computing capacity priced largely around those chips. Nvidia then backstops the lease. Each transaction appears to validate the one before it. Gary Tan of Allspring Global Investments described the problem: investors remain concerned about circular financing arrangements where a disappointment at any point in the loop can propagate quickly to the others.
The Bank for International Settlements has made the same point at a systemic level. A disappointment in AI returns, the BIS warned in a recent report cited by OilPrice, could trigger a sudden pullback in financing and turn the AI capital spending boom into a protracted investment bust. The Ohio guarantee exists in part to prevent exactly that outcome, assuring SoftBank that demand will materialize regardless of near-term market conditions. It is also, structurally, the scenario the guarantee makes more fragile, because the backstop’s credibility depends on conditions that neither Nvidia nor OpenAI fully controls.
The timing lands at the center of the AI industry’s most-watched earnings season. Big Technology companies are reporting quarterly results this week, with analysts pressing for evidence that the trillions committed to AI infrastructure are generating real, durable revenue. OpenAI CEO Sam Altman declared last weekend that AI has entered the singularity, a statement that also functions as a capital markets narrative addressed to the same investors now scrutinizing AI returns. OpenAI raised its spending forecast from $600 billion to $750 billion through 2030 earlier this year.
Nvidia has been deepening its financial role in the AI ecosystem beyond the OpenAI talks. In early July, Nvidia launched a revenue-sharing model under which it finances GPU buildouts and collects a recurring cut of cloud revenue from the same operators it sells hardware to. Chief financial officer Colette Kress described the resulting income as a recurring, usage-linked earnings stream. Analysts drew immediate comparisons to GE Capital’s equipment-financing model from the 1990s, which generated substantial recurring income until counterparty exposure to customer utilization rates became a liability the conglomerate spent years unwinding.
The Ohio project adds a dimension the revenue-sharing model does not have. GE Capital financed equipment; the Ohio arrangement would backstop real estate commitments at a scale that no private guarantor has previously attempted in the data center sector. The structural question of what happens to Nvidia’s balance sheet if OpenAI’s Ohio utilization disappoints the projections built into the guarantee has not been publicly addressed by either company.
Neither Nvidia nor OpenAI has confirmed the negotiations. The talks are described as early and non-binding, and both companies have declined to comment. What remains undisclosed is nearly everything that would allow an outside party to evaluate the risk: the guarantee’s precise legal structure, whether it is unconditional or conditioned on OpenAI’s own financial performance, the rent the Ohio campus charges, and whether any independent financial institution has reviewed the arrangement’s systemic exposure. The $250 billion figure has now been reported. The terms behind it have not.
