SoftBank-backed data center developer SB Energy plans to sell up to $500 million of newly issued shares to Japanese investors as part of its broader preparations for a public listing in the United States. The planned placement was disclosed in a September 15 filing and would give Japanese investors an opportunity to participate alongside the company's US initial public offering. SB Energy intends to use the proceeds to support its expanding data center, power generation, and related infrastructure operations.
Japanese Share Sale
The Japanese transaction will consist of new shares issued by SB Energy, rather than existing holdings sold by current shareholders, according to the filing. Funds raised from the placement are expected to be allocated toward general operating expenses associated with developing data centers, electricity generation assets, and supporting infrastructure. The filing did not disclose the number of shares that will be offered or the final price at which Japanese investors will participate.
US IPO Plans
SB Energy has separately filed a Form S-1 registration statement with the US Securities and Exchange Commission as it moves toward an American stock market debut. The publicly available filing has not yet specified the size of the IPO, the exchange on which the company's shares would trade, or a proposed ticker symbol. Reuters previously reported that SoftBank could seek a valuation of approximately $50 billion for the business, although a final valuation has not been announced.
Strategic Investors
The planned IPO has already attracted commitments from major technology companies seeking exposure to the infrastructure supporting artificial intelligence development. Nvidia has committed to invest $1.5 billion through a private placement priced at the IPO level, according to SB Energy's investment prospectus released earlier in September. The company has also issued warrants to OpenAI that were valued at roughly $5.5 billion in the prospectus, highlighting the growing relationship between AI developers and large-scale infrastructure providers.
Infrastructure Expansion
SB Energy's strategy centers on building energy-intensive computing infrastructure capable of supporting the rapid expansion of artificial intelligence and cloud workloads. Capital raised through the Japanese share placement and the US listing would provide additional resources for data center construction, power generation, and other infrastructure required to support future projects. The financing structure also reflects the substantial capital requirements facing developers seeking to expand computing capacity while securing reliable electricity supplies.
Market Context
Investor interest in AI-related companies and infrastructure has contributed to a broader wave of public market activity during 2026. Companies with exposure to artificial intelligence, computing capacity, and other technology infrastructure have increasingly sought public funding as demand for AI services drives investment across data centers, semiconductors, and energy systems. Japanese investors have also demonstrated significant appetite for prominent US listings, including a reported $2.2 billion allocation of shares in SpaceX's IPO earlier this year.
SB Energy's planned sale of up to $500 million in shares to Japanese investors adds another component to what could become one of the year's largest technology infrastructure listings. While the ultimate size, valuation, exchange, and pricing of the US IPO remain to be determined, commitments from Nvidia and the warrants issued to OpenAI underline the company's position within the expanding AI infrastructure ecosystem. The proceeds are expected to strengthen SB Energy's capacity to finance the data centers, power generation assets, and related projects needed to support its next phase of growth.
