Nikkei Asia reported that SoftBank Group is expanding its business from technology investments to AI infrastructure development, planning to invest $33 billion in Ohio to build a natural gas power plant and data center campus to meet OpenAI's needs. SoftBank's renewable energy subsidiary, SB Energy, has filed for a Nasdaq listing for this project, seeking a $50 billion valuation, but has postponed the listing due to volatility in AI-related stocks.
