Nvidia is reportedly weighing a financing guarantee for OpenAI that would tie the AI chip giant directly to a massive data centre project and to billions in chip purchases. The talks — reported by the Wall Street Journal and Bloomberg — have renewed market concerns about increasingly “circular” relationships in the AI supply chain and nudged investors to reprice the risk of close financial links between hardware suppliers and top model makers.
Reports: Nvidia may underwrite OpenAI’s Ohio data centre and chip purchases
According to reporting by the Wall Street Journal and Bloomberg, Nvidia has explored a plan to guarantee roughly $250 billion for an OpenAI data centre project in southern Ohio and to finance as much as $350 billion of OpenAI’s planned purchases of Nvidia chips. The Ohio facility is being developed by an arm of SoftBank, which the reports note sold its Nvidia shares in late 2025.
The reports say the arrangement would let the data centre developer “raise debt at more favorable terms than it could if OpenAI had no financial backer,” citing the Wall Street Journal. Nvidia and OpenAI did not comment on those reports, per Axios.
Markets reacted: Nvidia shares fell about 4.5% in late-morning trading on the day the reports surfaced, and credit default swaps tied to Nvidia bonds recorded their largest intraday increase since they began trading actively, according to ICE Data Services figures cited by Bloomberg.
How the proposed support would work and the other Nvidia moves
The core mechanics described in the reporting are straightforward: Nvidia would provide a financial backstop that improves the credit profile of the Ohio project and potentially enable OpenAI to secure chip purchases on more favorable terms. The underwriting would reduce perceived lending risk for the data centre developer, per the WSJ account.
Separately, Axios reports Nvidia announced a distinct partnership and investment with Safe Superintelligence, a startup founded by OpenAI co‑founder Ilya Sutskever. Nvidia said the deal gives it “rare access into the company’s closely guarded research,” and that it will let the startup “increase its compute by an order of magnitude” while collaborating on Nvidia’s current and future compute platforms. Details of that arrangement remain thin in public reporting.
The Ohio operation would be located on a decommissioned uranium enrichment site on federal land, and its power supply would come from a new $33 billion natural‑gas plant pledged by Japan, according to the same reporting. The Commerce Department would retain control over the power supply because of the site’s federal status, Axios reports.
Why it matters
The potential Nvidia guarantees matter for three linked reasons spelled out in the reporting. First, they represent a rare instance of a dominant supplier using its balance sheet to underwrite a major customer’s infrastructure and purchases, deepening commercial ties beyond the usual vendor–customer relationship. Second, such reciprocal backing can create systemic exposure: if either party faces a financial shock, the other could feel immediate stress — a dynamic market participants described as “circular.” Third, the arrangements drew a swift market reaction, with both Nvidia equity and credit insurance prices moving, indicating investors see this kind of tie as a material change to counterparty risk.
All three points are supported by the reporting: the proposed dollar amounts are very large, the WSJ explicitly frames the debt‑raising benefits for the developer, and ICE Data Services figures cited by Bloomberg document the market response.
Competitive and regulatory implications
The reports connect the financing discussion to broader questions about supply‑chain concentration and competitive dynamics in AI. A supplier that also backs a major model developer can alter bargaining positions with cloud providers and other customers, the reporting implies. That could reshape who controls access to the high‑end compute that powers large models and shift where model training happens.
Investors and counterparties are already pricing in the new counterparty exposures: the spike in Nvidia‑linked credit default swaps shows lenders and bond investors view these relationships as changing the risk profile of Nvidia debt. The reporting does not include regulatory responses, but the scale and nature of the ties underscore why competition and financial regulators will likely watch arrangements that entwine hardware suppliers, model makers, and infrastructure developers.
What to watch next
Public confirmation or denial: Neither Nvidia nor OpenAI commented in the reports; an official statement from either company would clarify deal structure, timing and financial commitments.
Deal terms and legal structure: Key unresolved questions include whether guarantees would be direct obligations, contingent commitments, or structured through third parties; the WSJ and Bloomberg reporting do not provide those specifics.
Market and credit signals: Watch for follow‑through moves in Nvidia share and bond markets and for further shifts in credit default swap pricing, which have already reacted to the reports.
Regulatory interest: Given the scale of the numbers reported, any formal inquiries or filings with financial or competition regulators would be material, though the sources offer no evidence of investigations at this stage.
Reports that Nvidia may underwrite parts of OpenAI’s infrastructure and chip buying program raise concrete questions about where commercial lines end and financial entanglements begin, and the market has already started to treat those questions as financially significant.
