SB Energy files for IPO with a $3.2 billion loss and one giant customer

Key points

• SB Energy filed for an initial public offering (IPO), meaning it is asking the public to buy shares in the company for the first time, with the US Securities and Exchange Commission on Tuesday.
• The company posted net losses of roughly $3.2 billion in the first half of 2026 while generating about $139 million in revenue, mostly from an older energy business.
• None of SB Energy's data centres are operational yet, and the company has not earned any revenue from that side of its business.
• Nvidia announced in August 2025 that it would provide $105 billion to finance an OpenAI data centre in Ohio that SB Energy will build.
• SB Energy plans to list on the Nasdaq stock exchange under the ticker symbol SBE, and is seeking to raise between $5 billion and $7 billion, according to reporting by CNBC Tech.

SB Energy builds the physical infrastructure that AI companies need: massive data centres filled with specialised computer chips, fed by large amounts of electrical power. The company is backed by SoftBank, OpenAI and Nvidia, and this week it took a significant step toward becoming a publicly traded company.

What did the filing actually say?

The document SB Energy submitted to regulators was unusually candid about its risks. The company told investors it is "substantially dependent" on OpenAI, which is both a paying tenant in its planned buildings and a shareholder.

That single relationship, the filing warned, ties SB Energy's near-term money, its building plans and its ability to borrow from lenders to OpenAI's continued health. If OpenAI runs into trouble, so does SB Energy.

The numbers paint a picture of a company in its early phase. For the first six months of 2026, SB Energy lost around $3.2 billion, almost all of it tied to the cost of building out its data centre strategy. Revenue in the same period came to about $139 million, almost entirely from a legacy power generation business that predates the AI build-out. The data centres themselves have yet to open their doors.

Where does Nvidia fit in?

Nvidia, the chip company whose graphics processing units (GPUs, the specialised chips that handle the heavy computing AI requires) power most large AI systems, announced in August that it would provide $105 billion in financing for an OpenAI data centre in Ohio that SB Energy will construct.

SB Energy's chief executive Rich Hossfeld explained the logic to CNBC's Squawk Box at the time: having Nvidia involved helps the company borrow money at better rates, because lenders treat a deal backed by a company of Nvidia's size as lower risk.

SoftBank is the controlling shareholder. SB Energy will trade on the Nasdaq under the ticker SBE, and the company could begin trading as soon as this month.

Should ordinary investors be cautious?

The company's own filing lists several concerns worth understanding before anyone considers buying shares.

Beyond the dependence on OpenAI, the company flagged that technological change could make its facilities outdated before they have fully paid for themselves. It also noted growing community opposition to data centres, including concerns about their energy use and local impact. Regulatory changes and the possibility that big tech companies slow their AI spending were listed as additional risks.

None of those warnings are reasons to panic. But they are reasons to read carefully.

Common questions

What is a data centre, exactly?

A data centre is a large building packed with computer servers, the machines that store data and run AI software. Companies like OpenAI rent space inside them rather than building their own.

Why does an AI company need so much power?

Running and training AI models takes enormous amounts of electricity, far more than ordinary office computing. Data centres require dedicated power supplies, often at the scale of a small power station.

What does "filing for an IPO" mean for regular people?

It means SB Energy has asked regulators to approve the sale of shares to the public. Once approved, anyone with a brokerage account could potentially buy a piece of the company.
