SB Energy's US IPO process, filed via S-1 on September 1, 2026, with a planned Nasdaq listing under ticker SBE, centers on its pivot from renewables to AI data center and power infrastructure. The company targets $5-7 billion in proceeds at a potential $50 billion-plus valuation, supported by Nvidia's $3 billion commitment through private placement and forward contracts, OpenAI's $5.5 billion in warrants plus major lease agreements, and SoftBank's controlling stake. Recent amended filings addressed SEC comments on Nvidia disclosures, while premarketing revealed investor pushback over the high valuation, zero operational data centers despite an 8.8 GW contracted portfolio, heavy first-half losses, and execution risks including permitting and community opposition. A Japanese retail tranche of up to $500 million is also planned, with roadshow timing now uncertain amid valuation gaps and broader AI infrastructure sentiment shifts.
