Analysis
SB Energy filed an amended Form S-1 with the SEC on September 4, according to the company's EDGAR filing history, advancing a listing that would be one of the largest of 2026. The SoftBank-backed company publicly filed its original registration on August 31 and has applied to list on the Nasdaq Global Select Market and Nasdaq Texas under the ticker SBE.
SB Energy develops, builds and operates gigawatt-scale data center campuses alongside the power generation and storage that feeds them -- solar, battery storage and gas. The filing in brief:
- Backlog: ~$439B total, ~$430B data center commitments and $10B standalone power
- Contracted capacity: 8.8 gigawatts in Texas and Ohio
- Targeted raise: $5B-$7B, per CNBC
- Nvidia commitment: $1.5B of non-voting Class N stock at the IPO price
“The number to check in the final prospectus is energized megawatts by quarter through 2027.”
The cap table reads like a map of the AI buildout. SoftBank is the controlling shareholder. OpenAI is both a strategic investor and a customer at its campuses. Nvidia is a strategic investor and residual value guarantor at the PORTS-Pike technology campus in Pike County, Ohio.
The financials are the counterweight to the backlog headline. SB Energy posted a net loss of $7.01 billion on revenue of $268.84 million for the twelve months ended June 30, and none of its data center capacity is currently in operation. That is a development-stage income statement attached to a backlog number larger than the market cap of most S&P 500 companies -- and the gap between the two is construction, interconnection and years.
Backlog of this type is a contracted pipeline across multi-decade agreements, not bookings that convert next quarter. Public investors will apply their own discount rate to the undiscounted total, and the range of reasonable answers is enormous.
Pulse covered the original filing on September 1, when the risk factors disclosed how substantially dependent the company is on OpenAI as a customer. What has changed since is procedural but consequential: the amendment moves SB Energy into the SEC comment cycle that precedes a price range, and pins the Nvidia placement into the deal structure. Its closest public comparables -- Vertiv, Bloom Energy, Equinix and Digital Realty -- carry no comparable loss profile, and Talen and Vistra trade on operating generation assets rather than pipeline.
The structural issue worth naming: Nvidia is investing in a company whose campuses will buy Nvidia systems, and OpenAI is an investor and tenant. Those arrangements are disclosed, but they make revenue quality harder to assess because customer, supplier and shareholder are the same parties.
The listing venue is itself a signal. Applying to both the Nasdaq Global Select Market and Nasdaq Texas ties the company to the state where most of its capacity sits, and where ERCOT's interconnection process determines the schedule everything else in the prospectus depends on. Texas regulators have also begun scrutinizing large flexible loads, a policy risk that did not exist when these campuses were contracted.
The number to check in the final prospectus is energized megawatts by quarter through 2027. Everything else in the filing depends on that schedule holding.
