As it prepares to go public, SB Energy, a SoftBank subsidiary, has offered warrants worth approximately $5.5 billion to attract OpenAI as a tenant for its data centers. Previously, OpenAI had already invested in SB Energy. SB Energy expects to release its IPO prospectus as early as this week and could complete its IPO as soon as next month, planning to raise $5 billion to $7 billion, though the terms have not yet been finalized. The IPO draft for the first time reveals the financial ties between SB Energy, SoftBank, and OpenAI, with its data center clients primarily being its investors.
