SB Energy funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Sep 2026 | Strategic investment | NVIDIA (lead) | $1.5B | NVIDIA agreed to invest $1.5 billion in SB Energy through a private placement of newly issued N class nonvoting shares, with the purchase priced at 90% of SB Energy’s IPO price and expected to close alongside the company’s U.S. listing in September 2026. The transaction is part of a broader capital commitment that brings NVIDIA’s total backing of SB Energy to $3 billion, combining this $1.5 billion share purchase with an earlier $1.5 billion investment tied to the company’s planned public offering. The investment supports SB Energy’s expansion as a data center developer tied to OpenAI infrastructure, including the PORTS-Pike Technology Campus in Ohio and the company’s wider AI compute buildout. NVIDIA is positioned as a strategic investor and customer, with the structure linking capital support to long-term compute supply and site development at the Ohio campus. SB Energy is a SoftBank-backed data center company that has been preparing for a U.S. IPO. The company’s platform is centered on large-scale AI infrastructure, with reported commitments around gigawatt-scale capacity at its Ohio campus and associated financing, customer, and supplier relationships designed to support rapid expansion. |
| Jan 2026 | Strategic investment | OpenAI (lead); SoftBank Group (lead) | $1B | SB Energy, a SoftBank Group company originally focused on renewable energy and storage development, has expanded into data center development and operations. On January 9, 2026, OpenAI and SoftBank Group each invested $500 million (total $1 billion equity) to support SB Energy's growth as a data center developer amid surging AI compute demand, as part of the Stargate initiative. OpenAI selected SB Energy to build and operate its 1.2 GW data center in Milam County, Texas, with the firms forming a preferred partnership for large-scale AI data center projects. This funding follows $800 million in redeemable preferred equity from Ares Infrastructure Opportunities in 2025, marking the third financing from Ares since 2020. SB Energy is developing multiple multi-gigawatt data center campuses, with initial facilities under construction and slated to enter service starting in 2026. The company recently acquired Studio 151 for data center construction expertise and plans to leverage OpenAI's APIs internally. |
| Mar 2022 | Undisclosed stage | Ares Management (lead) | $600M | SB Energy Global is SoftBank Group's U.S. Climate Infrastructure Technology platform focused on developing, financing, and operating renewable energy and storage projects. The company launched in the U.S. market in 2019 and had completed development, financing, and construction of nearly 1.7 GW of utility-scale solar projects by the time of the Ares investment announcement, with 1.3 GW currently operating in Texas and California. In March 2022, Ares Management's Infrastructure and Power strategy led a strategic equity investment of up to $600 million in SB Energy, with Ares-managed funds committing the majority of the capital and co-investors expected to provide the remainder. This investment launched a new chapter for SB Energy following an existing partnership with Ares that began in 2020. SB Energy's financing strategy included over $4 billion in tax equity and project financing from various financial institutions since inception. The company aimed to deliver 10 GW of renewable energy and storage projects in operation or under construction by the end of 2025, and was aggressively expanding through greenfield development, partnerships, acquisitions, and digital technology capabilities. The investment combined Ares' climate infrastructure expertise, SoftBank's AI and technology ecosystem, and SB Energy's proven execution track record to scale flexible renewable energy deployment. |
