OpenAI is planning to build five new data centers in the United States as part of the Stargate initiative, the company announced on Tuesday. The move follows an agreement Oracle and OpenAI announced in July to develop up to 4.5 gigawatts of US data center capacity on top of what the two companies are already building at the first Stargate facility in Abilene. The two remaining sites are being helmed by OpenAI and SB Energy, a SoftBank subsidiary that develops solar and battery projects. The flagship site in Abilene is primarily owned and operated by Oracle, with OpenAI acting as the primary tenant, according to executives close to the project. It is already running on Oracle Cloud Infrastructure and supporting OpenAI training and inference workloads, those sources add.
