Details

OpenAI and SoftBank Group have each invested $500 million, for a total of $1 billion, in SB Energy, entering into a strategic partnership to address AI computing demand. This collaboration is part of the Stargate project, which aims to build next-generation AI and energy infrastructure in the United States.

OpenAI has selected SB Energy to build and operate a 1.2 GW data center site in Milam County, Texas. SB Energy is currently developing multiple gigawatt (GW)-scale data center campuses, with full-scale service expected to begin in 2026.

The two companies will jointly develop a new data center construction model that combines OpenAI's data center design technology with SB Energy's energy supply and execution capabilities. In addition, SB Energy plans to utilize OpenAI's API and roll out ChatGPT to its employees.

This project aims to promote sustainable economic growth through local job creation, workforce development, and power grid modernization. In particular, the data center design will minimize water usage, and new power generation facilities will be built to meet electricity demand.
