SB Energy's IPO process, centered on its pivot from renewables to AI data center infrastructure, faces ongoing valuation scrutiny after filing its S-1 in early September 2026. The SoftBank-backed firm targets a $50 billion-plus valuation and $5-7 billion raise to fund 8.8 gigawatts of contracted data center capacity in Texas and Ohio, backed by Nvidia's $3 billion commitment and OpenAI as anchor tenant with substantial warrants. Investor pushback on pricing has delayed the roadshow from late September plans, prompting amended disclosures and a potential mid-to-late October launch amid broader AI infrastructure market caution. Key upcoming catalysts include SEC comment resolution, Japanese investor tranche execution, and any new capacity or partnership announcements that could clarify execution risks in this high-growth but loss-making segment.
