Recent investor skepticism over SB Energy's targeted valuation above $50 billion, combined with the company's limited operating history and lack of data center revenue, has driven significant delays in its IPO process. The SoftBank-backed firm filed its S-1 in early September 2026 for a Nasdaq listing to fund AI infrastructure projects, highlighting Nvidia's $3 billion commitment and major power contracts, yet premarketing feedback revealed a valuation gap that prompted postponement of the roadshow. With SEC review ongoing and broader market caution around AI spending sustainability, traders see little chance of closing before January 2027. A strong rebound in tech sentiment or resolved pricing could still accelerate timing, though historical patterns for complex infrastructure IPOs suggest extended preparation remains likely.
