SB Energy, a data centre and power infrastructure company backed by SoftBank Group, plans to raise up to $500 million from Japanese investors as part of its planned IPO in the United States.
The company will issue new shares to Japanese investors. The money will support its business costs and help fund the development of data centres, power generation facilities and related infrastructure.
The plan comes at a time when demand for AI infrastructure has grown at a very fast pace. AI companies need large data centres, huge amounts of power and advanced computing systems. SB Energy wants to build the infrastructure that can support this demand.
The latest share sale gives Japanese investors a chance to take part in the SB Energy IPO before its US market debut. However, the company has not yet disclosed the final size of its US IPO.
A SoftBank-backed AI infrastructure company
SB Energy has strong links with SoftBank Group, one of Japan’s biggest technology investment companies. SoftBank is also expected to remain the controlling shareholder after the IPO.
SB Energy focuses on power and data centre projects that can support large AI workloads. Its business is different from that of a normal technology company. It does not mainly sell software or consumer products. Instead, it aims to provide the physical infrastructure that AI companies need.
That includes data centres, power facilities and energy storage projects.
This makes SB Energy part of a much larger change in the technology sector. AI growth has created a new need for land, electricity, data centres and computing capacity. Companies such as OpenAI and Nvidia need large amounts of infrastructure to support future AI services.
SB Energy is trying to position itself at the centre of this demand.
Japan investors could invest up to $500 million
According to a company filing released on Tuesday, September 15, SB Energy plans to sell up to $500 million of new shares to Japanese investors.
The proceeds will go to the company rather than existing shareholders because these are new shares. SB Energy says it plans to use the funds for general business needs, including data centre development, power generation and related infrastructure projects.
The exact amount that the company will raise may change before the final IPO terms are set.
The Japanese share sale is part of the wider plan for the US IPO. SB Energy has applied for a Nasdaq listing, but the final US IPO size and price have not yet been disclosed.
This means investors still do not have a complete picture of the final IPO. The company has to settle the price, share count and other key terms before the public offer can be completed.
Nvidia has committed $1.5 billion
One of the biggest reasons SB Energy has attracted attention is its relationship with Nvidia.
Nvidia has committed to invest $1.5 billion in SB Energy at the IPO price through a private placement. This is separate from the $500 million share sale planned for Japanese investors.
Nvidia is the world’s leading supplier of AI chips, so its involvement gives SB Energy a strong connection with the AI infrastructure market.
The Nvidia investment also shows how closely the AI chip business is linked with the data centre business. Powerful AI systems need large amounts of computing capacity. That computing capacity needs data centres, electricity and supporting infrastructure.
Nvidia has also announced a major role at SB Energy’s planned PORTS-Pike Technology Campus in Ohio. The project is designed to support Nvidia AI computing, with OpenAI as the customer.
OpenAI has received major warrants
OpenAI is another major name linked to SB Energy.
According to SB Energy’s investment prospectus, OpenAI has received warrants worth about $5.5 billion.
A warrant gives the holder the right to buy shares under certain terms. The value of OpenAI’s warrants shows how important the relationship between the two companies could become.
OpenAI is expected to be a major customer for SB Energy’s planned data centre projects. The company needs a huge amount of computing infrastructure as it expands its AI products and services.
This relationship gives SB Energy a potential source of long-term demand. At the same time, it also means that investors will pay close attention to the company’s ability to build its planned projects on time.
The IPO could value SB Energy at $50 billion
The final IPO valuation has not been disclosed.
However, earlier Reuters reports said SoftBank may seek a valuation of about $50 billion for SB Energy. The company has also been linked to reports of a possible multi-billion-dollar US IPO.
That would make the listing one of the more important IPOs connected to the AI infrastructure boom.
A valuation of $50 billion would also place a large value on SB Energy’s future business rather than only its current operations. This is important because much of the company’s growth depends on projects that are still under development.
Investors will therefore need to look beyond the headline valuation. They will want to know how quickly SB Energy can turn its planned projects into operating assets and real revenue.
Why AI has become important for the IPO
The timing of SB Energy’s IPO is closely linked to the global AI boom.
AI companies need much more computing power than traditional software businesses. Large AI models require thousands of advanced chips and huge data centres. These facilities also need reliable electricity and strong power networks.
As AI use grows, demand for this infrastructure has also increased.
This has created new opportunities for companies that build and operate data centres and power systems. SB Energy wants to use this trend to build a large business around AI infrastructure.
The company is not alone. Several other AI-related firms have also moved closer to public markets this year. SpaceX listed in June, while Anthropic is expected to pursue a listing later this year, according to Reuters. Japanese investors also secured $2.2 billion of SpaceX shares in its IPO.
The business also carries risks
The strong AI connection does not remove the risks.
SB Energy has to build large and expensive projects. Data centres and power facilities require huge amounts of capital, land, equipment and electricity. Delays can increase costs and push back revenue.
The company also depends on long-term demand from large technology customers.
Earlier reports about its IPO noted that some of its planned projects will take years to become operational. Its PORTS-Pike project in Ohio, for example, is expected to come online in phases from 2028.
That means investors who buy shares in the IPO may have to wait several years before some of the company’s biggest projects produce their expected results.
What the $500 million means
The planned $500 million Japanese share sale is important because it provides SB Energy with fresh capital before its US market debut.
The money can help the company meet its near-term costs and support its infrastructure plans. It also gives Japanese investors direct access to a company with major links to SoftBank, Nvidia and OpenAI.
The deal also shows the growing connection between Japan’s investment market and the US technology market.
SB Energy has not yet disclosed the final size of its US IPO. The company will need to provide more details before investors can assess the full offer.
A closely watched IPO
SB Energy’s planned IPO has attracted attention because several major technology names are connected to the company.
SoftBank remains its main backer. Nvidia has committed $1.5 billion at the IPO price. OpenAI has received warrants worth about $5.5 billion. Japanese investors may buy up to $500 million of new shares.
Together, these figures show why the company has become an important name in the current IPO market.
Still, the story is not only about AI excitement. SB Energy must turn its plans into real data centres, power facilities and long-term revenue. The company faces the usual risks of large infrastructure projects, along with the added pressure that comes with a high-profile public listing.
For investors, the next major details will be the final IPO size, valuation, share price and listing date. Until those details are clear, the planned $500 million Japanese share sale remains one important part of a much larger US IPO story.
