SB Energy's filed S-1 in early September 2026 targeted a roughly $50 billion valuation to fund AI data center and power infrastructure buildout in Texas and Ohio, backed by Nvidia's $3 billion commitment and OpenAI ties. However, premarketing revealed a valuation gap, with investors pushing back amid cooling sentiment toward AI infrastructure spending sustainability, community opposition to data centers, and execution risks on a massive unproven backlog. This led to a delayed roadshow after SEC review, pushing any close well beyond early 2027. Strong trader consensus on no IPO before January 2027 reflects these near-term barriers, though faster sentiment recovery or revised pricing could still accelerate timing.
