⚡IPO Brief⚡ SoftBank-backed AI power and data center infrastructure company SB Energy publicly filed its S-1 registration statement with the SEC on September 1, planning to list on Nasdaq Global Select Market and Nasdaq Texas under the ticker "SBE." The number of shares and price range have not yet been disclosed. The financials show a stark contrast: for the six months ended June 30, 2026, the company reported revenue of $138.7 million, up 66.4% year-over-year, while its net loss widened to $3.21 billion, compared with $215.5 million a year earlier. According to the Wall Street Journal's reporting on the IPO materials, the widened loss was driven largely by changes in the estimated fair value of warrant liabilities, and shouldn't be read simply as a year-over-year deterioration in operating losses. Reuters previously reported, citing people familiar with the matter, that SB Energy could seek a valuation above $50 billion and list as early as September. That valuation, the offering size, and final pricing have not been confirmed by the company in its S-1. SB Energy doesn't develop AI models or chips; it provides the physical foundation AI compute expansion requires: developing, building, and operating large-scale data center campuses, integrated with power and energy infrastructure. In January 2026, OpenAI and SoftBank each invested $500 million, and OpenAI selected SB Energy to build and operate its 1.2GW data center project in Milam County, Texas. Nvidia's capital and credit support arrangements stand out in particular: Nvidia has previously disclosed a $1.5 billion investment in SB Energy, and has committed in the S-1 to an additional $1.5 billion investment via a private placement at the IPO price — together, roughly $3 billion in equity commitments. Separately, for the lease arrangement covering roughly 4.25GW of IT load at SB Energy's PORTS Technology Campus in Ohio, Nvidia is providing guarantees of up to $105 billion, phased in and triggered only under specified tenant-default conditions defined in the agreement; OpenAI has agreed to reimburse Nvidia for any payments made under that guarantee. This figure represents a maximum credit-support ceiling, not a direct cash outlay by Nvidia. Underwriters listed in the offering materials include JPMorgan, Goldman Sachs, Morgan Stanley, Citigroup, and Mizuho. What the market will really be assessing isn't just revenue growth, but whether a capital structure shaped by long-term leases, customer credit quality, warrant arrangements, and enormous guarantees can support its large-scale AI data center expansion.
