Nvidia has agreed to provide up to $105 billion in financial guarantees to support OpenAI’s lease of a massive AI data center being developed in Ohio by SoftBank-owned SB Energy.

The chipmaker will also invest $1.5 billion in SB Energy, adding to earlier funding from OpenAI and SoftBank. Nvidia will serve as the exclusive chip supplier for the facility, which could eventually reach 8 gigawatts of capacity, with the first 800 megawatts expected to come online in 2028.

OpenAI has signed a 20-year lease for the Pike County site. Nvidia’s guarantee will cover portions of lease and power obligations while also protecting a minimum value for the facility if OpenAI defaults.

The arrangement reflects Nvidia’s growing role in financing the infrastructure built around its processors. While the strategy supports long-term demand for its AI chips, it has also raised investor concerns about increasingly interconnected funding relationships across the AI sector.

CEO Jensen Huang said the company is using its financial strength and long-term visibility to secure infrastructure where Nvidia hardware can operate across multiple generations.

The Ohio project will also require major energy investment. SoftBank and SB Energy plan to develop at least 10 gigawatts of new power generation and invest billions in regional grid infrastructure to support the site.
