Nvidia is reportedly in discussions to provide approximately $250 billion in financial backing for OpenAI to secure lease and construction financing for a planned 10-gigawatt data center campus in southern Ohio being developed by SoftBank's energy unit. The overall project could exceed $500 billion when equipment costs are included, and a separate financing arrangement for Nvidia chip purchases is also under discussion. Talks are ongoing and terms remain unsettled.

Key Points

  • Nvidia is reported to be negotiating to provide about $250 billion in guarantees to support OpenAI's lease and construction financing for a planned 10-gigawatt data center campus in southern Ohio developed by SoftBank's energy subsidiary.
  • The total cost of the project could exceed $500 billion when equipment such as Nvidia chips is included; chip purchases themselves are being discussed under a separate financing arrangement estimated at about $350 billion.
  • The first phase is intended to supply approximately 800 megawatts of power and is targeted for completion in 2028; the guarantee would not cover chip purchases and talks remain ongoing.

Overview

Nvidia is in active discussions to provide roughly $250 billion as a financial guarantee to support OpenAI in leasing and financing construction of a planned 10-gigawatt data center campus in southern Ohio being developed by SoftBank's energy subsidiary. The proposed backing would be directed at reducing lenders' concerns tied to OpenAI's credit profile and enabling more favorable borrowing terms for the developer.

Scale and scope

Officials involved in the talks indicate the full development could ultimately cost in excess of $500 billion once equipment — including Nvidia chips to populate the facilities — is taken into account. The guarantee under consideration would explicitly cover lease obligations and the construction financing for the campus, and would not extend to the direct purchase of chips.

Separate chip financing

In addition to the lease and construction guarantee, Nvidia is reported to be in conversations about a distinct financing arrangement to support OpenAI's acquisition of chips, a component that could amount to roughly $350 billion. That arrangement would be separate from the guarantee aimed at securing the site-level financing.

Project timing and power

The initial phase of the Ohio campus is intended to deliver about 800 megawatts of power and is targeted for completion in 2028. The development is being planned as a large-scale data center campus capable of supporting significant artificial intelligence workloads.

Ongoing negotiations and uncertainty

Discussions between the parties are continuing and the precise terms have not been finalized. Because the arrangements remain under negotiation, there is a possibility the agreements could fail to materialize.

Implications for financing and markets

A guarantee of this magnitude would be among the largest financing commitments associated with artificial intelligence infrastructure. By offering such backing, Nvidia would aim to alleviate lender concerns stemming from OpenAI's lack of an investment-grade credit rating, enabling the developer to access debt under more favorable conditions than might otherwise be available.


Note: The status of the conversations is fluid and the terms under discussion may change.

Risks

  • The negotiations are not finalized and the proposed agreements could fall apart, creating uncertainty for lenders, the developer, and equipment suppliers - impacts span finance, semiconductors, and data center construction sectors.
  • OpenAI's lack of an investment-grade credit rating is cited as a lender concern; if the guarantee is not provided or accepted, securing debt on favorable terms could be more difficult for the project - affecting capital markets and developers.
  • Chip purchases are not covered by the proposed guarantee and require a separate financing arrangement; failure to finalize that separate financing could affect equipment supply and project cost dynamics - relevant to the semiconductor and cloud infrastructure markets.
