Nvidia is in talks to guarantee roughly $250 billion in lease and construction financing for an OpenAI data center campus, according to a report from WION.

The money would fund a 10-gigawatt campus in Piketon, Ohio. Under the arrangement described by WION, Nvidia would be on the hook if OpenAI cannot pay — a backstop that, as the outlet's headline puts it, exists because the banks wouldn't take on the risk themselves.

That structure is unusual enough to explain the framing in both reports: the company selling the chips would also be underwriting the borrowing that pays for the buildings those chips go into. If OpenAI's revenue doesn't keep pace with its construction commitments, the obligation lands back on Nvidia's balance sheet rather than on a lender's.

Markets have not reacted uniformly. Benzinga reports that Nvidia stock is still up, but that the $250 billion AI risk has spooked the debt market — a split worth noting, since equity investors and bond investors are pricing the same deal differently. Stock buyers are weighing the upside of enormous chip demand; debt markets are weighing who ultimately pays if the buildout disappoints.

Ten gigawatts is a very large amount of power for a single computing campus, and the financing figure reflects that scale. The reporting describes negotiations, not a completed agreement, so terms could change.

Why it matters: when the biggest supplier in the AI boom starts guaranteeing its own customer's debt, the industry's growth and its risk stop being separate things — and a slowdown at OpenAI would no longer stay at OpenAI.
