Nvidia Reportedly Weighs $250B Backstop for OpenAI's Ohio Megacampus

The eye-catching number is $250 billion, but the interesting part is the shape of the deal. The Wall Street Journal reported that Nvidia is in talks to guarantee roughly $250 billion of financing tied to OpenAI's lease of a 10-gigawatt data center campus in southern Ohio, with SoftBank's SB Energy as developer. A chip vendor underwriting its largest customer's real estate obligations, at a scale that rivals sovereign infrastructure programs, is a genuinely new financing primitive.

The site itself is unusual. The campus would sit on federal land in Pike County, the former Portsmouth uranium enrichment plant that produced weapons-grade material during the Cold War before ceasing operations in 2001, per Network World's summary of The Information's reporting. OpenAI would sign a 20-year lease with SB Energy, controlling the equipment and paying rent once operations start, with the first 800-megawatt phase targeted for 2028. The full buildout is estimated at around $500 billion at current prices for chips, labor and power, a figure that echoes the original Stargate headline number.

Why a guarantee, and why now. A backstop is not cash up front; it is a promise to cover payments if the tenant or the project falls short. That kind of credit support can lower the interest rate and lengthen the tenor on the debt SB Energy raises, because lenders effectively underwrite Nvidia's balance sheet rather than a single-site AI campus with one customer. It also lets OpenAI commit to a decades-long lease without holding investment-grade credit itself. The circularity is the awkward part: Nvidia is guaranteeing the obligations of the customer that will buy Nvidia's chips, financed on the strength of Nvidia's own credit.

The honest caveat is that the specifics are single-sourced reporting on talks in progress. WSJ describes the $250 billion figure as what is being discussed, and Nvidia, OpenAI and the Commerce Department did not comment. What the reporting does not give you is the legal shape of the guarantee, how it lands on Nvidia's balance sheet, or how it composes with Nvidia's separately reported intent to invest up to $100 billion in OpenAI as systems deploy. Take the numbers as reported, not settled.

If the structure holds, expect it to be copied. Google is already reported to be backstopping Anthropic's roughly $35 billion TPU lease obligations across several US sites, and cheaper capital for chip-backed leases is exactly the kind of weapon Nvidia would want to extend to other hyperscale customers who cannot self-finance at this scale.
