OpenAI, SoftBank to Invest $1 Billion in SB Energy in New Partnership

By Katherine Hamilton


SoftBank's company SB Energy is working with OpenAI to help develop its artificial-intelligence infrastructure platform Stargate.

OpenAI and SoftBank are each investing $500 million into SB Energy as part of the partnership.

The owner of ChatGPT also selected SB Energy to build and operate its previously announced 1.2 gigawatt data center site in Milam County, Texas. The project is expected to create thousands of construction jobs, OpenAI said.

As part of the deal, OpenAI, SoftBank and SB Energy have formed a preferred partnership to develop a new model for data-center builds.

SB Energy also secured $800 million of redeemable preferred equity from Ares to support its growth.

SB Energy is currently developing several multi-gigawatt data-center campuses, which are expected to enter service starting this year.
