# SB Energy IPO and AI infrastructure development > Live situation record from CLSTR: https://clstr.news/situations/sb-energy-ipo-and-ai-infrastructure-development > Updated: 2026-09-06T18:00:38.000Z. Sources: 17. Developments: 2. SB Energy, a SoftBank-majority-owned developer of power and data center infrastructure, has filed for an initial public offering (IPO) in the United States. The company is targeting a raise of between $5 billion and $7 billion. To support its growth as an AI infrastructure provider, SB Energy has secured significant involvement from major technology firms. OpenAI has invested $500 million and is expected to hold a single-digit stake following the IPO, while Nvidia has committed $3 billion through private placement and forward contracts, including providing up to $105 billion in residual-value guarantees for the PORTS-Pike Technology Campus in Ohio. Despite a contracted data-center backlog valued between $400 billion and $439 billion, the company reported a net loss of approximately $3.21 billion for the first half of 2026, largely due to the rising valuation of warrant liabilities issued to OpenAI. As the company seeks to scale its projects, it faces industry-wide challenges including energy access, labor scarcity, and lengthy electrical grid interconnection processes. ## Timeline ### 2026-09-06: SB Energy seeks New York IPO for data center projects SoftBank subsidiary SB Energy seeks a New York IPO to fund data center projects, facing industry challenges like energy interconnection delays and material shortages amid a massive AI infrastructure boom. 2 sources. https://clstr.news/cluster/sb-energy-seeks-new-york-ipo-for-data-center-projects ### 2026-08-31: SB Energy files for Nasdaq IPO targeting $5-7 billion raise SB Energy, a SoftBank-owned developer, has filed for a $5-7 billion Nasdaq IPO, leveraging a $400 billion+ data center backlog and strategic partnerships with OpenAI and Nvidia to expand AI infrastructure. 15 sources. https://clstr.news/cluster/sb-energy-grants-openai-55b-in-warrants-for-20-year-lease --- Cite as: SB Energy IPO and AI infrastructure development.
