A company with zero operating data centers just filed to go public at a $50 billion valuationSB Energy's S-1

SB Energy, the SoftBank-backed AI power infrastructure company, filed a registration statement with the Securities and Exchange Commission on September 1 for a proposed Nasdaq IPO under the ticker SBE, targeting a raise between $5 billion and $7 billion, according to the S-1 filed directly with the SEC.[1] The filing's own risk-factor language is unusually direct about the concentration risk sitting at the center of the business: "This concentration means that our near-term revenues, project-level financing arrangements, and development plans are significantly linked to OpenAI's continued performance under our lease and related agreements," according to CNBC's review of the filing.[2] Elsewhere in the document, SB Energy states plainly that it is "substantially dependent" on OpenAI's performance as both a tenant and an equity investor.
The scale of that dependence is visible in the filing's own word frequency, a detail flagged in reporting on the document: OpenAI is mentioned 306 times throughout the S-1, nearly as often as SoftBank itself at 325 mentions, while Nvidia appears 135 times.[3] For a company preparing to ask public market investors for billions of dollars, that concentration of a single counterparty's name across its own founding disclosure document is itself a data point worth sitting with before looking at anything else in the filing.
A Company Asking to Be Valued Before It Has Revenue to Show For It
The most structurally unusual fact in this IPO is not a hidden detail buried in a footnote, it is stated outright: SB Energy currently has zero operational data centers. According to Reuters' reporting via BNN Bloomberg, the company has not generated any revenue from its data center segment as of the filing date, and its first data center revenue is not expected to arrive until the fourth quarter of this year.[4] For the first half of 2026, SB Energy posted net losses of roughly $3.2 billion against approximately $139 million in revenue, and that revenue itself came mostly from the company's legacy energy business rather than the AI data center operations the IPO is centered around, according to the Energy News Today account of the filing.
Against that, SB Energy is presenting investors with a contracted backlog of roughly $439 billion, a figure drawn almost entirely from long-term data center and power generation leases rather than delivered, revenue-generating infrastructure. IPOX Research Associate Lukas Muehlbauer, quoted in the Reuters account, framed the core investor question plainly: "Investors have to be convinced that hundreds of billions of contracted demand can be turned into cash flow over the coming years." That is the entire thesis of this IPO compressed into one sentence, a bet on execution against a backlog, not a bet on an already-functioning business.
What OpenAI and Nvidia Actually Committed, In the Filing's Own Numbers
The specific financial mechanics tying SB Energy to its two largest partners are laid out in granular detail across the filing, and they are worth separating from the round summary figures circulating in coverage. According to Securities.io's detailed reading of the registration statement, Nvidia contractually committed to purchase $1.5 billion of a new, non-voting class of equity called Class N common stock in a private placement closing concurrently with the IPO, priced at the same level as the public offering price.[5] Separately, the filing describes a prepaid forward contract dated August 17, 2026, under which Nvidia prepaid an additional $1.5 billion to an SB Energy affiliate, Energy Global LP, for delivery of Class N shares at 90% of the eventual IPO price, a structure that gives Nvidia a built-in discount on its second tranche of exposure regardless of where the stock ultimately prices.
OpenAI's position is structured differently and comes with governance rights attached. The filing discloses that OpenAI holds 3,991,809 warrants at a nominal exercise price of $0.01 per share, and, according to the Quartz account of the filing, will retain a board designation right for as long as its ownership stake in SB Energy exceeds 5% of the company's outstanding capital stock. Combined with the disclosed lease arrangements, OpenAI's relationship with SB Energy spans customer, equity holder, warrant holder and board-influence positions simultaneously, a level of structural entanglement between a single customer and its infrastructure provider that goes well beyond a typical landlord-tenant relationship.
The Flagship Project Behind the Numbers
The centerpiece asset underlying SB Energy's backlog is a specific physical campus, and understanding its scale clarifies why the dollar figures involved are as large as they are. The Ports-Pike Technology campus in Ohio, described in the Quartz reporting as SB Energy's flagship development, is being built through a joint effort involving SB Energy, OpenAI and Nvidia, and is designed to draw 10 gigawatts of gross power load from the grid at full build-out. This is the same Ohio campus Depth Grid referenced earlier this month when covering Nvidia's separate $500 billion Wall Street financing alliance, where reporting noted Nvidia was separately in talks to guarantee financing for a quarter-trillion-dollar AI data center project tied to OpenAI. SB Energy's S-1 is effectively the first public, audited-adjacent look at the financial structure underneath that same physical buildout.
SB Energy's total contracted data center capacity across its full pipeline stands at 8.8 gigawatts, of which only 803 megawatts, roughly 9% of the total, is actively under construction, according to the Quartz figures. The company's standalone solar and battery storage portfolio, its original legacy business before the AI data center pivot, totals a separate 5.5 gigawatts. That split matters for reading the filing accurately: SB Energy is not purely a data center startup, it is an established power infrastructure developer that has redirected the overwhelming majority of its growth narrative and forward capital toward AI compute demand specifically.
The Filing's Own Warning About Circular Financing
SB Energy's S-1 does not shy away from the structural criticism this deal invites, and reporting on the filing has connected it directly to a pattern that has defined much of 2026's AI infrastructure financing. Reuters' coverage noted explicitly that this wave of multi-billion-dollar AI, cloud and chip deals has sharpened scrutiny around what critics call AI's circular economy, arrangements where the biggest funders of AI infrastructure are simultaneously its biggest customers. The companies involved have consistently said these deals are not circular financing but rather investments meant to accelerate the AI buildout, and SB Energy's own framing follows that same line.
This is a pattern Depth Grid has tracked closely through Nvidia's disclosed equity stakes in SpaceX and Intel, both companies that separately pledged Nvidia chip exclusivity, and through Nvidia's contested reported acquisition of Hugging Face earlier this week. SB Energy's IPO extends that same structural pattern into the physical infrastructure layer, rather than the chip supply or model access layers those earlier stories covered. Nvidia is not just providing chips, it is a direct equity investor in the company that will house the servers those chips run on, and OpenAI is not just a tenant, it is simultaneously an equity holder with board influence in its own landlord.
Public Backlash Made the Risk-Factor List Here Too
SB Energy's filing includes a risk-factor disclosure that echoes language Depth Grid covered in detail when Anthropic's own IPO filing was reported to name AI backlash as a formal risk earlier this month. According to CNBC's reporting, SB Energy's prospectus states directly: "We may face community opposition, local moratoria and hyper-local dissent, including growing public resistance to AI and AI-related infrastructure, that may adversely affect our data center and power generation businesses and operations." Seeing that same specific risk category, once treated as an unusual disclosure, now appear in a second major AI-adjacent IPO filing within the same month suggests this language is quickly becoming standard practice across the sector rather than an isolated instance of unusual corporate candor.
What to Watch Next
SB Energy's registration statement confirms the company will remain a "controlled company" under SoftBank after the listing, meaning SoftBank retains majority voting control regardless of how the public float trades, a governance structure that limits how much influence new public shareholders will actually have over the company's direction. A confidential version of this S-1 was first filed back on May 20, 2026, according to Cryptobriefing's reporting, meaning today's public filing is the culmination of a roughly three-and-a-half-month private review process with the SEC. With a public listing targeted for late September 2026, the clearest next signal will be the actual price range SB Energy sets for its shares, since that number, measured against the disclosed $439 billion backlog and near-total absence of current operating revenue, will be the market's first real test of how much credit investors are willing to extend to contracted demand that has not yet been converted into anything operational.
