Wall Street biggies JPMorgan, Goldman Sachs, Morgan Stanley and Citi, along with their Japanese counterpart Mizuho, in terms of helping SoftBank Group, a Japan-based multinational conglomerate and one of the world’s largest technology investment holding companies, to prepare its initial public offerings (IPOs) for its energy and infrastructure subsidiary SB Energy, along with the group’s planned autonomous robotics spinout Roze.
The news comes amid SoftBank founder and CEO Masayoshi Son ramping up the Japanese group’s push into artificial intelligence (AI) infrastructure amid strong investor appetite for companies underpinning AI buildout.
As per the reports, SB Energy’s IPO could come as early as September 2026, with the climate infrastructure and technology platform, known for developing, constructing, and operating large-scale renewable power and AI data centres in the United States, seeking a valuation of over USD 50 billion in its market debut.
“At the same time, SoftBank has tapped Goldman Sachs, JPMorgan, Mizuho and Morgan Stanley for the IPO of its autonomous robotics company Roze, which will focus on building data centres and using robotics to improve the efficiency of AI infrastructure construction and is targeting a similar time frame,” Reuters reported.
Talking about SB Energy, the energy and infrastructure developer that pairs power generation with data centres to help “Big Tech” address AI’s growing energy constraints is also a key partner, along with OpenAI and SoftBank, for the US government-backed USD 500 billion “Stargate” initiative.
SB Energy will be building and operating a 1.2-gigawatt data centre campus in Texas to support OpenAI’s computing needs. The facility will be powered by an integrated solar and battery storage system. OpenAI has also committed USD 500 million to SB Energy as part of a joint USD 1 billion investment with SoftBank.
Roze, on the other hand, is a planned SoftBank spinoff that aims to deploy autonomous robotics to speed up the construction of large-scale AI infrastructure, including data centres, helping the manufacturing and infrastructure players address labour and construction bottlenecks as demand for AI capacity surges.
SoftBank’s twin IPO push, if concluded successfully, will mark 2026 a major year for market debuts, with a wave of mega AI listings, including SpaceX, Anthropic and OpenAI, expected to test investor appetite for large new issues.
The IPO would also validate how the AI boom is expanding beyond traditional data centres into so-called “picks-and-shovels businesses” that support the ecosystem, from power generation and energy supply to machines that can help build and run next-generation facilities.
