NEW YORK — AI infrastructure developer SB Energy is moving toward the U.S. public markets with an initial public offering that could value the company at more than $50 billion, highlighting the enormous investor interest surrounding the infrastructure required to power artificial intelligence.
The SoftBank-backed company filed for a Nasdaq listing on September 1 after reporting a 66.4% increase in first-half revenue. SB Energy said its revenue reached $138.7 million during the first six months of 2026, although it recorded a $3.21 billion net loss.
AI Infrastructure Becomes an Investment Theme
SB Energy is developing large-scale data-center capacity designed to serve customers with enormous computing requirements.
The company currently has approximately 8.8 gigawatts of contracted or under-construction capacity.
That figure illustrates the scale of electricity and computing infrastructure required by the latest generation of AI systems.
The AI industry has created a new investment category around data centers, power generation, cooling systems and semiconductor infrastructure.
Major technology companies are committing enormous sums to expand computing capacity.
SB Energy's filing provides investors with another opportunity to participate in that infrastructure boom through public markets.
Nvidia has also committed $1.5 billion to invest in the company at the IPO price, while OpenAI has received warrants worth approximately $5.5 billion, according to the filing.
The proposed listing nevertheless carries substantial risk.
SB Energy is currently generating losses while investing heavily in infrastructure.
Investors must determine whether future demand for AI computing will be large enough to justify today's valuations.
The IPO could therefore become an important test of Wall Street's appetite for companies supporting the AI economy.
If successful, it could encourage additional infrastructure companies to pursue public listings.
