SB Energy to raise up to $500 million from Japanese investors ahead of U.S. IPO

SB Energy, supported by SoftBank Group, intends to offer up to $500 million of new shares to Japanese investors as part of its public offering in the United States. The capital raised will be allocated to general operating costs for expanding data-centre facilities, power-generation assets and associated infrastructure. The prospectus did not reveal the overall size of the U.S. IPO, though SoftBank may target a $50 billion valuation for the firm.

Nvidia has committed $1.5 billion in a private placement at the IPO price, and OpenAI has been granted warrants worth about $5.5 billion. The move follows a wave of AI-focused public listings, including SpaceX’s June debut, which attracted $2.2 billion from Japanese investors, and the upcoming listing of Anthropic.
