Nvidia's $105 Billion Ohio Guarantee Is Becoming the AI Industry's Financing Template

When Nvidia filed a Form 8-K on 17 August disclosing up to $105 billion of exposure tied to OpenAI's new Ohio data centre, most coverage treated it as one large number attached to one large customer. The filing describes something narrower: a residual value guaranty, the same instrument Meta used to finance its Hyperion campus in Louisiana ten months earlier, and the mechanism Nvidia is now offering across a $500 billion financing platform it announced a week earlier.

Three of the largest AI campuses built this year have been financed the same way inside twelve months, which matters more than the headline figure, because it changes what a datacentre lender or power-purchase counterparty actually needs to underwrite.

What the filing actually promises

Under the agreements, Nvidia is not paying OpenAI's rent. It has guaranteed the residual value of roughly 4.25 gigawatts of leased capacity at the PORTS-Pike campus in Pike County, with an option, at its own discretion, to extend the same support to a further 3.8 gigawatts.

The payment obligation only exists if OpenAI defaults on its 20-year lease or becomes insolvent, and even then SB Energy has to try to re-lease or sell the site first. The $105 billion is a capped, worst-case number, phased in only as leases commence from 2028, and it shrinks as OpenAI pays rent. OpenAI has separately agreed to reimburse and indemnify Nvidia for anything it actually pays out, an indemnity hardest to collect at exactly the moment it would matter. Asked whether this amounted to circular financing, Nvidia flowing money to a customer who spends it on Nvidia chips, CEO Jensen Huang wrote that it did not, because OpenAI is the one paying the lease.

That answer is accurate on its own terms, but it settles a narrower question than whose name is on the rent cheque: whose credit makes the lease financeable at all. The guarantee dissolves the moment OpenAI achieves a satisfactory credit rating on its own, which is the tell that it is functioning as a substitute for one.

The instrument already has two precedents

Meta financed Hyperion through a joint venture with Blue Owl Capital, backed by a 16-year residual value guarantee tied to Meta's own credit. S&P rated the resulting bonds A+, one notch below Meta's own AA-minus, because it reads the guarantee as Meta risk dressed in a project-finance structure. A week before the Ohio filing, Nvidia signed memoranda of understanding with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR to raise over $500 billion for AI infrastructure, with Nvidia offering its own residual value backstop on a portion of each deal.

That backdrop reframes the Ohio number. Three companies have converged on the same instrument inside a year, each lending its own credit rating to make a tenant's lease financeable when the tenant's credit could not.

The credit market is already grading it

Nvidia's five-year credit default swap spread, the cost of insuring its debt against default, jumped the most on record in a single day on 27 July, after reports surfaced that Nvidia was discussing financing above $750 billion across its AI customers, rising to roughly 82 basis points from around 42 in late June. By 29 July, Reuters reported the spread near 78 basis points, above Meta's 93 and well below Oracle's roughly 200, as bond investors differentiated between which AI-exposed balance sheets carried the most contingent risk. By the time the Ohio guarantee landed at $105 billion, down from the roughly $250 billion first reported in July, the swaps market had already priced a chipmaker absorbing the kind of obligation once reserved for infrastructure funds and insurers.

That repricing argues against calling any of this hidden. It was disclosed in an 8-K the same day it was signed, and bond prices moved within hours. What has not caught up is the underwriting on comparable deals elsewhere. The same week, Blackstone's data-centre arm QTS signed a much smaller Texas solar contract structured through a third-party generator, the more conventional way this risk has been allocated until now, pushing delivery risk onto an intermediary rather than onto the data-centre owner. The Securities and Exchange Commission also issued guidance in July exempting some data-centre debt from the risk-retention rules Dodd-Frank imposed on securitizations after 2008, which will make it easier to package guarantees like this one into tradeable debt without a sponsor holding a matching share of the downside.

If you do not trade credit derivatives, the mechanics still reach you. Pension funds and insurers holding Nvidia stock or bonds are, through this guarantee, exposed to whether OpenAI can pay rent on a campus that will not open until 2028. Ohio electricity customers are exposed differently: SB Energy and AEP Ohio are committing $4.2 billion to new grid infrastructure for this campus, a cost regulators will eventually allocate between the project and the ratepayers who share the same wires. Neither group signed a lease. Both now sit somewhere on a chain running from OpenAI's revenue growth to Nvidia's balance sheet to the transformer down the street.

None of this means the guarantee gets drawn. Huang's argument, that Nvidia compute is fungible enough to be re-let or resold if OpenAI falters, is testable rather than settled, and the obligation only phases in as leases commence and shrinks as rent gets paid. The question worth tracking is whether datacentre lenders and PPA counterparties are underwriting a utility's ability to deliver power on schedule, or a chipmaker's ability to absorb a downturn in AI demand. Three of the largest AI campuses built this year assume the second question matters more, and nobody will know which underwriting was right until a lease payment is actually missed.
