SB Energy's IPO reveals data center and gas

SoftBank subsidiary SB Energy has filed for an initial public offering aiming to raise between $5 billion and $7 billion. The company, founded in 2019 as a renewables developer, now calls itself an integrated data center and power infrastructure company after pivoting in 2025.

The filing reveals a dramatic shift in strategy. SB Energy's operational assets consist solely of approximately 2.2 gigawatts of solar and battery energy storage system projects in California and Texas. It has no data center or gas generation capacity currently in operation.

The PORTS-Pike Technology Campus

SB Energy is the developer behind the planned PORTS-Pike Technology Campus, one of the country's largest proposed data centers. The campus would be backed by 10 gigawatts of power infrastructure, with almost all of that coming from new fossil gas generation. It is to be built on federal land and has already secured OpenAI as a tenant. The project is not expected to come online before 2028.

The company's S-1 filing explicitly states the risks. It notes that no data center capacity is currently in operation, with its first two data center projects under construction while the PORTS-Pike project is not. The filing warns there can be no assurance that these projects or any other project will be completed on the anticipated timeline or at all.

Financials and Market Context

The filing shows $138.7 million in revenue for the first half of 2026 against a $439 billion backlog. A staggering $430 billion of that backlog comes from data centers, which are not expected to produce any revenue until at least the end of the year. The company warns that long lead times for power equipment and growing opposition to data centers could hinder future growth.

SB Energy is riding the wave of AI infrastructure demand to an IPO. It follows companies like CoreWeave, which went public in 2025 with revenue and customers, and Fermi America, which filed in September 2025 with no revenue and no customers at all.

The Gas Generation Question

A key uncertainty surrounds the development of the 9.2-gigawatt gas power plant meant to supply the campus. The filing deliberately distances SB Energy from ownership of this critical infrastructure. The plant will be built on land adjacent to the data center campus and will be owned by the U.S. government.

The filing states that SB Energy is developing and will own and operate the data center site, but does not expect to own or operate the gas-fired generation facilities. It clarifies that the facilities are being developed by an affiliate of SoftBank that is not its subsidiary, and that they have not been financed, constructed, or contracted yet. Necessary permits and approvals are the responsibility of that separate developer.

While SB Energy says it is investing in the initial development of large-scale gas plants to supply its data centers, the filing does not explicitly link these investments to the PORTS-Pike project. This distancing is notable because the gas plant's success is fundamental to the campus's operation. Relying on the already capacity-constrained PJM grid to supply the full load is seen as an unlikely alternative.

The company's decision to pursue such a large, complex infrastructure project with limited operating history, and under public market scrutiny, marks a significant gamble for the SoftBank-backed firm.
