OpenAI is pursuing a 10GW Ohio datacenter campus as part of a potential $500 billion AI infrastructure investment.

According to reporting from The Information, OpenAI is in discussions to lease a proposed 10-gigawatt data center campus in Ohio, a project that could become one of the largest artificial intelligence infrastructure developments ever undertaken. The planned facility could cost at least $500 billion to build when factoring in expenses such as AI chips, construction labor, power generation, and other infrastructure requirements. If finalized, the project would significantly expand OpenAI's computing capacity as demand for advanced AI models continues to rise.

Under the reported arrangement, OpenAI would lease the facility for 20 years and maintain control over the computing equipment housed at the site, with lease payments beginning once the data center becomes operational in 2028. The development is reportedly being led by SB Energy, a SoftBank subsidiary, on land owned by the U.S. Department of Energy in southern Ohio. Nvidia is expected to play a central role by supplying AI hardware for the facility and could also provide a financial guarantee to support OpenAI's lease commitments and SB Energy's project financing efforts.

Reuters noted that it could not independently verify the report, and OpenAI and Nvidia did not immediately respond to requests for comment outside normal business hours. The reported Ohio project comes as competition intensifies among leading AI companies to secure large-scale computing resources. Earlier this year, OpenAI paused its proposed Stargate data center initiative in the United Kingdom, citing regulatory challenges and elevated energy costs.

AI infrastructure investments continue to accelerate across the industry, with Apollo Global Management and Blackstone backing a $35 billion AI capacity expansion project for Anthropic, which will utilize Broadcom-powered technology to support growing artificial intelligence workloads. If completed, the Ohio facility would represent a major milestone in the global race to build the next generation of AI data centers and high-performance computing infrastructure.
