SB Energy, which describes itself as a Softbank-, OpenAI-, and Nvidia-backed provider of infrastructure to power artificial intelligence, submitted its IPO documents to the SEC on Tuesday. The company plans to list on Nasdaq and Nasdaq Texas with the ticker SBE. It has not announced pricing or a specific debut timeline. The Wall Street Journal reported the stock could start trading as soon as this month and that SB Energy is targeting between $5 billion and $7 billion in proceeds. Softbank remains the controlling shareholder.
SB Energy says it leans on partner financing to build its data center campuses, has not booked any revenue from that segment yet, and none of its data centers are currently operational. For the first half of 2026, it recorded roughly $3.2 billion in net losses and brought in approximately $139 million in revenue, primarily from its legacy energy operations.

The filing underscores just how closely tied SB Energy is to OpenAI, both as a tenant and an equity investor, and notes that OpenAI CEO Sam Altman invested personally early on. As the company puts it, "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."
SB Energy also cautions that community pushback is rising. "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," the prospectus says. Other risks it calls out include technological advances that could make facilities obsolete or hard to market, slower adoption of AI by businesses, regulatory shifts, and decelerating capital spending by hyperscalers.
SB Energy is pitching a massive buildout for the AI age while its core data center assets are still in development. The bull case is straightforward if AI demand keeps compounding. The caution signs are, too: heavy reliance on a few partners, no operational data centers yet, and a tougher climate in communities and policy circles. If trading kicks off soon with a multibillion-dollar raise, the question for everyday investors is whether the company can turn plans into working sites and cash flow while those uncertainties play out.
