Nvidia's $105B Financing for OpenAI's Ohio Data Center

OpenAI signed a 20-year lease with SB Energy for a data center that will scale to 8 gigawatts of AI compute capacity ^[1], with rent paid directly from OpenAI to SB Energy as the site's owner and operator ^[2]. But the deal only works because Nvidia stands behind it: if OpenAI defaults, Nvidia covers the gap between the site's guaranteed minimum value and whatever SB Energy can recoup by re-leasing or selling it ^[2].

That backstop exists because OpenAI, despite an $852 billion valuation, remains unprofitable and lacks an investment-grade credit rating - the kind of balance sheet lenders typically require before financing an infrastructure project of this scale ^[3]. Without Nvidia's guarantee, banks would have little basis to lend the tens of billions needed to build out the campus; with it, OpenAI's promise to pay effectively becomes Nvidia's promise to pay. Nvidia isn't merely a chip vendor to this project - it is functioning as OpenAI's credit rating, absorbing default risk so that a company still burning cash can commit to two decades of rent on one of the largest data center campuses ever proposed.

As recently as late July 2026, Nvidia was reportedly weighing a guarantee as large as $250 billion so OpenAI could lease SoftBank's planned 10-gigawatt Ohio campus ^[4]. Bernstein analyst Stacy Rasgon warned the structure would 'clearly fuel circular concerns' ^[5]. By mid-August, the guarantee had reportedly been cut to under $120 billion after investors raised concerns about Nvidia's risk exposure tied to large financing commitments ^[3], and the finalized number announced August 17 came in at $105 billion.

The skepticism hasn't faded just because the number shrank. Jefferies technology strategist Jeffrey Favuzza described the reported financing arrangement as the clearest and largest example yet of potential circular financing in the AI buildout ^[6]- Nvidia capital underwriting a customer that spends it on Nvidia chips, while Nvidia separately holds an equity stake in that same customer. Jensen Huang has pushed back directly on the label, framing the guarantee as infrastructure investment rather than a circular loop ^[7]. On YouTube, commentary on the deal has drawn a direct parallel to AMD's earlier backstop of Anthropic's data-center leases, framing both as cases where a chip supplier co-signs financing because the AI lab (or its landlord) isn't independently creditworthy - suggesting this kind of vendor-backed guarantee is becoming a pattern across the industry rather than a one-off. Community discussion on Reddit tracks a similar fault line, debating whether Nvidia's earlier investment announcements were binding commitments or non-binding letters of intent, and raising the round-trip concern directly: Nvidia backstopping financing for a customer that turns around and spends it on Nvidia chips.

The PORTS-Pike Technology Campus sits on the site of the decommissioned Portsmouth Gaseous Diffusion Plant, a former uranium enrichment facility in Pike County, Ohio ^[8]. Around that history, the deal is packaged with concrete regional commitments: SB Energy and OpenAI are funding an $80 million community benefits fund, and SoftBank-backed SB Energy is putting at least $4.2 billion into regional grid infrastructure through a partnership with AEP Ohio ^[8].

The jobs numbers are the headline for the region: about 35,000 construction jobs through 2032 and 2,500 long-term operating positions ^[1], powered by at least 10 gigawatts of new energy generation with the first 800-megawatt phase expected online by 2028 ^[2]. For a county whose defining industrial asset was a Cold War-era enrichment plant that shut down years ago, the pitch is a second act built on the opposite kind of infrastructure - compute instead of enriched uranium, but at a scale few local economies have ever absorbed at once.

Huang has framed the guarantee less as a financing favor and more as a land grab: 'AI is becoming infrastructure - the foundation for intelligence in every industry - and land, power and shell have become vital in the age of AI' ^[1]. Under that framing, Nvidia isn't just protecting OpenAI's ability to pay rent - it's locking down physical capacity (land, electricity, and building shells) before competitors can, then making itself the exclusive AI compute infrastructure provider for whatever gets built on it ^[8].

That exclusivity is the real payoff for Nvidia. The Ohio guarantee traces back to a September 2025 letter of intent in which Nvidia committed to invest up to $100 billion in OpenAI progressively as each of 10 gigawatts of Nvidia systems came online ^[9]- a structure that ties Nvidia's capital directly to Nvidia hardware deployment. Every gigawatt Nvidia helps finance into existence is a gigawatt that, by contract, runs on Nvidia chips. If land, power, and shell really are the next bottleneck industry-wide, as Huang argues, then guaranteeing the debt that builds them is a way for Nvidia to buy first claim on the scarcest resource in AI - not compute itself, but the physical capacity to house it.
