SB Energy IPO discloses $439B backlog, OpenAI as anchor tenant
The gist
The filing puts concrete numbers on the scale of AI-driven data center demand, with a single customer relationship accounting for a substantial portion of SB Energy's contracted revenue. Nvidia's phased guarantee structure gives SB Energy financing support before most planned capacity generates lease revenue.
The full picture
SB Energy, backed by SoftBank, filed for a US IPO disclosing a contracted backlog of $439 billion covering 8.8GW of planned data-center capacity. OpenAI is the primary customer, having signed leases expected to account for a major share of SB Energy's near-term data-center revenue; OpenAI also invested $500 million and received warrants valued at approximately $5.5 billion. Nvidia committed $1.5 billion at the IPO price and is providing guarantees capped at $105 billion covering 4.25GW of OpenAI leases in Ohio, with those guarantees activating in phases as facilities are completed.
