⚡️ SB Energy is going public
If you have been watching the race to power the AI boom, this is one of the most aggressive bets on physical infrastructure yet.
The stakes just got higher. With AI leaders like Dario Amodei and Sam Altman openly discussing a more cautious pace at the frontier, investors face a fundamental question. How durable is the physical infrastructure buildout if frontier development slows?
SB Energy sits right at the center of that question.
The company generated just $139 million of revenue in the first half of 2026. It now reports roughly $439 billion of contracted backlog, almost entirely tied to data centers.
There’s one catch. None of those data centers are operating yet.
SB Energy started as a renewable-power developer. The AI boom has transformed it into something much bigger. It now develops gigawatt-scale data centers and the power infrastructure behind them, with OpenAI as its largest customer and NVIDIA and SoftBank helping fund the buildout.
In effect, SB Energy is becoming a physical landlord of the AI boom, owning the infrastructure underneath the compute.
The gap between SB Energy’s revenue today and the future revenue already under contract is the entire IPO story.

1. Overview
SB Energy’s transformation is easy to see in one place: Milam County, Texas.
In 2024, the company completed the Orion Solar Belt, a 900 MW solar complex with Google as its anchor customer. Two years later, SB Energy is building a 1.2 GW data center campus for OpenAI in the exact same county.
That captures the entire evolution of the company. SB Energy went from supplying clean power to third-party facilities to building and owning the physical data centers themselves. Milam County was only the beginning.
Mastering the grid (2019–2023)
SB Energy was founded in 2019 as a SoftBank Group company focused on large-scale renewable energy. It spent its early years mastering the hardest parts of infrastructure development: finding land, securing grid connections, contracting power, arranging project debt, and managing construction over multi-year cycles.
Those capabilities once looked like the plumbing of a slow-moving utility business. The AI boom changed that overnight.
Hyperscalers need massive compute, but chips are only part of the bottleneck. Gigawatt-scale data centers require land, high-voltage electricity, transmission access, environmental permits, and years of buildout. SB Energy already knew how to solve many of those problems.
Moving up the stack
Instead of remaining an upstream power supplier, the company moved up the stack. It now operates as an integrated data center and power platform, developing the physical infrastructure where AI hardware will live.
The scale changed rapidly. At its PORTS-Pike campus in Ohio, SB Energy has contracted 8 GW of capacity for OpenAI, with NVIDIA providing the compute infrastructure and initial phases coming online in 2028.
Across its portfolio, the company reports roughly 5 GW of power projects operating or under construction, along with three AI campuses in development.
SB Energy doesn't design chips, train AI models, or rent cloud instances. Its bet is on the land, power, and buildings that AI systems require.
Takeaway: SB Energy spent its first five years learning how to build power infrastructure at utility scale. The AI boom turned that expertise into physical infrastructure for the AI economy.

SB Energy monetizes that infrastructure through three segments:
