SoftBank-backed SB Energy eyes US IPO for data center expansion
SB Energy, a Redwood City, California-based digital infrastructure company backed by SoftBank, said it plans to confidentially file for a US initial public offering as it targets demand for power projects tied to AI data centers.
Over the past year, the company has raised more than US$1.8 billion from SoftBank, OpenAI, and Ares Management for those plans.
In February, SB Energy outlined a US$33 billion, 9.2 gigawatt natural gas plant in Piketon, Ohio, to supply an AI data center project on a former uranium enrichment site.
In January, OpenAI and SoftBank each invested US$500 million and chose SB Energy to build and operate OpenAI’s 1.2 gigawatt data center in Milam County, Texas.

🧠 Food for thought
Implications, context, and why it matters.
SB Energy’s AI push rests on big solar contracts and U.S. Department of Energy-leased land
- Before its recent OpenAI deals, SB Energy had already lined up large power commitments for tech customers. In 2022, it agreed to supply Google with 942 megawatts from four solar projects in Texas 1.
- The company also uses federal land for some projects, which can speed development.
- Its Ohio AI data center project is planned on leased land at the U.S. Department of Energy (DOE) Portsmouth Site in Ohio through a public-private partnership 2.
- Public descriptions have paired the Ohio site with a dedicated natural gas plant plus solar and battery storage. The provided DOE Portsmouth announcement materials do not confirm those energy details 3.
AI is pushing tech companies deeper into the power business
- SB Energy describes its approach as running both data center development and power supply in the U.S., which fits a wider shift in the industry 4.
- The power grid is already under strain. AI adds enough demand that many new data centers now factor in electricity supply from the start 3.
- That makes power planning a business edge. Companies building AI services are getting more involved in generation so they can secure enough electricity to operate.
- One reason is scale. Data centers could use as much as 12% of U.S. electricity by 2030 5.
