Nvidia as Guarantor: OpenAI's Ohio Bet Exposes AI Capex's Debt Problem

Nvidia is reportedly in talks to guarantee OpenAI's lease obligations on a proposed 10 GW Ohio campus, not just supply the chips, and that distinction matters.
Key takeaways
- Nvidia is in talks to act as financial guarantor for both OpenAI's lease and developer SB Energy's project financing on a proposed 10 GW Ohio data center campus that could cost $500 billion to build, first reported by The Information on June 9, 2026.
- The structure is circular: Nvidia guarantees OpenAI's ability to pay for Nvidia's own hardware, exposing a financing gap that conventional debt markets have not filled on their own.
- A 10 GW campus powered by 9.2 GW of new natural gas generation is a direct competitor for the dispatchable power supply Bitcoin miners have occupied, and the debt mechanics underwriting it rhyme with every fiat-financed bubble that came before.
Nvidia is in talks to serve as financial guarantor for OpenAI's lease obligations and developer SB Energy's project financing on a proposed 10-gigawatt data center campus on federal land in southern Ohio, according to The Information. The campus, to be built on the former Portsmouth Gaseous Diffusion Plant site in Pike County, could cost at least $500 billion at current prices for chips, labor, power, and construction. No final deal has been signed.
SB Energy, a SoftBank unit, would develop the facility. OpenAI would control computing equipment under a 20-year lease, with payments beginning once operations start. The first phase is expected online in 2028. The Department of Energy announced the public-private partnership to redevelop the Pike County site in March 2026, with AEP Ohio named as the utility partner. SB Energy has committed to building at least 9.2 GW of natural gas-powered generation to supply the campus.
A Chipmaker Becomes the Lender of Last Resort
Nvidia's role here goes well beyond selling GPUs. As guarantor, Nvidia is on the hook if OpenAI defaults on lease payments or if SB Energy cannot service its project financing. That is contingent balance-sheet liability, not a chip sale or an equity stake.
This is Nvidia's second attempt at a major financial commitment to OpenAI. In September 2025, the two companies announced a letter of intent for Nvidia to deploy 10 GW of systems and invest up to $100 billion in OpenAI. By February 2026, Jensen Huang was calling that deal "never a commitment." Nvidia ultimately invested in OpenAI's $122 billion funding round at an $852 billion valuation, but the equity slice was $30 billion, not $100 billion. The guarantee structure is the third iteration, and it is structurally different from either of the prior two: it is debt support, not equity.
The circularity is the tell. OpenAI CFO Sarah Friar has acknowledged that "most of the money will go back to Nvidia" in GPU purchases. Now Nvidia is guaranteeing OpenAI's capacity to make those very payments. That is vendor financing dressed as infrastructure investment. When a chipmaker must backstop its customer's debt to keep its own revenue flywheel turning, the demand for compute has outrun the supply of creditworthy buyers.
Separately, Apollo and Blackstone are financing a $35 billion AI capacity expansion for Anthropic using Broadcom chips, per Reuters. The pattern is the same: hardware suppliers and private credit filling gaps that traditional lenders will not.
What This Means for Energy and Sound Money
A 10 GW campus is not an abstraction. Ten gigawatts is roughly the peak electricity demand of New York City. Powered by 9.2 GW of new dedicated natural gas generation, this facility would represent one of the largest single power loads ever brought online in the United States. TFTC has covered the hard ceiling communities and regulators are already pushing back against AI buildout, and OpenAI's own separate 3.2 GW gas contract in Georgia shows this Ohio campus is part of a pattern, not an isolated bet.
For Bitcoin miners, the implications are direct. Miners have spent years as the buyer of first resort for stranded, curtailable, or otherwise unmonetizable power. AI data centers locking up firm power contracts with Nvidia's balance sheet behind them are competing for the same dispatchable generation. The Pike County campus coming online in 2028 will not squeeze miners overnight, but it narrows the geography of cheap, reliable power and raises the floor on what "stranded" means.
The macro overlay is harder to ignore. The financing required for a single AI campus at this scale exceeds what conventional high-yield credit markets can absorb in any single issuance cycle. Numbers at that scale do not get funded through conventional credit markets.
They get funded through vendor backstops, sovereign guarantees, or they do not get funded at all. Every path that is not orderly private credit is, in some form, inflationary. Inflationary outcomes are constructive for hard assets.
What to Watch
The thesis breaks if Nvidia walks away from the guarantor role as cleanly as it walked back the $100 billion equity commitment, or if OpenAI secures conventional project financing from institutional lenders without needing Nvidia's backstop at all. A clean third-party debt raise on market terms would be evidence the economics are self-sustaining.
Until that happens, watch whether SB Energy can close construction financing independently and whether any public DOE loan guarantee appears behind this deal. If a federal backstop materializes, the circular structure gets bigger, not smaller. OpenAI and Nvidia did not respond to requests for comment on the guarantee arrangement.

Frequently Asked Questions
A lease guarantee means that if OpenAI cannot make its payment obligations under the 20-year lease, Nvidia is contractually obligated to cover them. It is contingent liability sitting on Nvidia's balance sheet. Unlike an equity investment, where the downside is limited to the amount invested, a guarantee can require the guarantor to fund the full outstanding obligation if the primary party defaults. At Nvidia's current scale the absolute dollar exposure may be manageable, but the precedent matters: chipmakers are being asked to function as infrastructure banks.
Stargate was a $500 billion joint venture announced in January 2025 with Oracle, SoftBank, and OpenAI that made "little progress," per The Information. The Ohio campus repositions SoftBank's involvement through its SB Energy subsidiary and substitutes Nvidia as the key financial principal in place of Oracle. The site, the former Portsmouth Gaseous Diffusion Plant, is DOE-owned land, which is what made the March 2026 public-private partnership announcement possible.
If OpenAI's revenue does not scale fast enough to service the lease, the guarantee triggers and Nvidia absorbs the shortfall. That scenario would put a chipmaker in the position of owning or operating stranded AI infrastructure it built its own revenue model around. The incentive to avoid that outcome is strong, which is partly why the circular structure persists: unwinding it is more painful than extending it.
