SB Energy, the SoftBank Group unit, announced a strategic alliance with OpenAI as part of the Stargate program, which pushes for the construction of next‑generation energy infrastructure and data centers in the United States. The joint investment and the lease for a large 1.2 GW site are a concrete step to scale the computing power needed for large AI models.
What they agreed
OpenAI and SoftBank Group are each investing $500 million into SB Energy, for a total of $1,000 million aimed at accelerating the development of data center campuses and associated energy infrastructure.
OpenAI also signed a lease for 1.2 GW for the initial site in Milam County, Texas, which will be the first to be built and is planned to come online starting in 2026.
SB Energy also secured $800 million in additional redeemable preferred equity from Ares to support its growth.
