The prospectus for SB Energy's upcoming flotation reveals striking details: a staggering $430 billion pipeline of data center contracts paired with zero operational sites, and lease terms that could grant OpenAI rent-free periods if construction slips. SoftBank-backed SB Energy, an energy and data center developer, is targeting an initial public offering as soon as this month, and its filing is packed with eyebrow-raising disclosures. For starters, all three planned data center facilities are still in the pre-operational stage.

The company also has intricate commercial entanglements with SoftBank, OpenAI, and Nvidia. Yet an even more blunt reality makes this IPO distinctly unconventional. Infrastructure development is inherently a high-risk endeavor with volatile returns, a profile that tends to repel public market investors. "For a typical development firm, the earnings model is quite unfavorable," said Ted Brandt, CEO of Marathon Capital, an investment bank focused on clean energy. Development cycles routinely stretch across multiple years and demand enormous upfront capital, meaning a company can post losses for years before assets generate cash flow. Businesses that already own a portfolio of income-producing assets, such as listed power generators NextEra Energy Resources and Vistra Energy, face far less strain on their finances. Similarly, data center developers like Digital Realty Trust and Equinix went public with operational facilities already generating revenue.

Beyond these structural hurdles, the data center development arena has become intensely crowded, with newcomers emerging at a rapid clip. According to data services firm Cleanview, some 360 companies in the United States have at least one data center project on the drawing board. When stacked against a field of speculative entrants, SB Energy does carry certain advantages. It is a seasoned energy project developer, having built solar and storage ventures since 2019. The company has also secured a potential revenue pipeline totaling $430 billion, anchored by OpenAI as the primary customer with Nvidia providing some backup support. The business model offers respectable margin potential: operational costs, insurance premiums, and property taxes are all passed through to clients, while customers supply their own computing hardware.

Nevertheless, roughly 82% of that contracted backlog will not materialize for at least eight years. The filing indicates that "the vast majority of revenue" traces back to a massive undertaking in Ohio called PORTS-Pike Technology Park, which carries a total electrical load of 10 gigawatts. This single project accounts for 90% of SB Energy's entire data center contract capacity, with phased commissioning planned between 2028 and 2032. The average contract term approaches two decades, and some backlog revenue may not be realized until the middle of the century. Such extended timelines mean the company will burn through cash and report losses for a considerable stretch. SB Energy forecasts capital expenditures for these data centers alone at $174 billion, most of which will be debt-financed, generating substantial interest obligations.

Another layer of risk: the flagship PORTS-Pike facility depends on a 9.2-gigawatt natural gas power plant that SB Energy neither owns nor operates. The prospectus states that a SoftBank-affiliated entity will develop the power station—not an SB Energy subsidiary—with funding sourced from both U.S. government and Japanese backers. Yet to date, no binding agreements covering financing, construction, ownership, or operations have been secured for that plant. SB Energy is also seeking 10 gigawatts of grid interconnection capacity, but most of those approvals have yet to be granted. The company further cautions that, in addition to grid access, projects may require supplemental power procurement. Realizing the contracted revenue depends on every condition falling into place simultaneously.

The entire data center industry is currently under intense public scrutiny, and this undertaking is itself riddled with uncertainty. SB Energy still needs to obtain multiple permits, secure final interconnection approvals, and ensure timely delivery of electrical equipment. It also plans to borrow against the OpenAI contract, even though OpenAI lacks a credit rating and only Nvidia provides partial support. Delays carry tangible consequences. Under the terms of the contract, if the PORTS-Pike project misses its commissioning deadline, SB Energy must waive one day of base rent for OpenAI for every day of delay; once the postponement exceeds 90 days, the rent-free period doubles. The filing also reveals that if the data center project in Milam County, Texas, is delayed by a year, OpenAI gains a purchase option to acquire that facility at a price "significantly below" the rental income SB Energy would otherwise have earned. SB Energy holds a monumental backlog of future orders. But for investors, translating that potential into realized gains requires a vast array of elements to align at precisely the right moments.
