Nvidia is in talks to invest as much as $3 billion in SB Energy, the SoftBank subsidiary building OpenAI's planned Ohio data center, as part of a wider deal that reportedly includes Nvidia providing around $100 billion in credit support for the project. A separately reported Nvidia guarantee tied to OpenAI's data center buildout runs as high as $250 billion.
Nvidia is in talks to invest as much as $3 billion in SB Energy, the SoftBank Group subsidiary developing a massive planned data center campus for OpenAI in Ohio, the Information reported on Saturday, citing people familiar with the discussions. Reuters said it could not immediately verify the report.
Investment tied to a $100 billion credit package
The potential Nvidia investment is being discussed as part of the chipmaker's broader negotiations with OpenAI and SB Energy, which reportedly include Nvidia providing around $100 billion in credit support for the Ohio data center campus.
A separate $250 billion guarantee reported earlier
According to Crypto Briefing, citing a Wall Street Journal report from July 26, Nvidia was separately in talks to guarantee approximately $250 billion in financing that would let OpenAI lease SB Energy's planned 10-gigawatt data center in Ohio's Piketon area, built on land controlled by the US Department of Energy. Without an investment-grade credit rating, OpenAI would leave SB Energy facing steeper borrowing costs, so Nvidia's guarantee would let its landlord borrow as if its tenant carried one, the report said. Phase one of the project targets approximately 800 MW of generation capacity by 2028.
Stargate's costs keep climbing
OpenAI and SoftBank each committed $500 million to SB Energy in January 2026, totaling $1 billion earmarked for AI data center infrastructure across the US. Nvidia issued a letter of intent in 2025 to deploy at least 10 GW worth of Nvidia systems, with the first gigawatt targeted for the second half of 2026. Total costs for the Stargate initiative could potentially exceed $500 billion once chips and related infrastructure are included. Financing for the chips and accelerators alone is estimated at around $350 billion.
There's still a possibility the deal could fall through, given the complexity of the financing discussions.
