SB Energy Files for IPO With Nvidia Backing

By Katherine Hamilton


SB Energy, an AI infrastructure platform backed by SoftBank, has registered for an initial public offering.

The company, which is majority-owned by Masayoshi Son's SoftBank, said Tuesday it plans to trade on Nasdaq under the symbol SBE, and hasn't yet determined the number or pricing of shares in the proposed offering.

SB Energy aims to raise between $5 billion and $7 billion, the Wall Street Journal has reported.

As part of the offering, Nvidia has committed to buy $1.5 billion of a new class of non-voting equity securities in a private placement at a price per share equal to the IPO price. That commitment is scheduled to close simultaneously with the IPO's closing.

The Journal has also reported that OpenAI has issued warrants worth an estimated $5.5 billion in SB Energy.

SB Energy said it intends to offer shares to retail investors who are tax residents and located in the U.K. via a public offer platform operated by Marex Financial.
