SoftBank shares jumped nearly 20% over two trading sessions after reports linked the company to potential IPO plans for OpenAI and SB Energy. The rise took SoftBank's stock to its highest levels in months, according to Bloomberg and MarketWatch.
In a sign of continuing investor appetite for stocks related to artificial intelligence, the transfer is set to take place. After significant investment pledges from major tech firms this year, investors have been keeping a close eye on companies and infrastructure in the era of AI.
There is revival of IPO activity
SB Energy disclosed on May 20 that it is seeking to go public in the US through a confidential listing process through Reuters. The company's business involves the development of solar and battery storage projects and their operations are principally in North America.
The filing marks a bounce-back in the IPO market following a lull that started in 2023 and continued through early 2024, due to rising interest rates that slowed down listings. Several recent large filings and fundraising rounds have been in the technology, energy infrastructure and AI-related businesses.
The company has been also reported to be discussing a timeline for and structure of its IPO, but no official details have been shared publicly.
AI Spending Remains Key Driver
SoftBank's exposure to semiconductor, data infrastructure and technology investments via its Vision Fund portfolio has been driving its stock movements along with the market's overall sentiment towards AI.
IDC recently released a research report that predicts an estimated $630 billion will be spent on AI globally by 2028. The United States is still the biggest market for AI investment, and Japan, the Middle East, and parts of Europe have seen a surge in funding for semiconductor technologies, cloud infrastructure and data centers.
The new trend in AI investments comes on the heels of several recent earnings reports from top chip makers and cloud firms, which indicated ongoing demand for AI computing infrastructure.
Latest Financial Position
In the fiscal year 2026, ending in March, SoftBank improved its net earnings to 1.15 trillion yen, after posting red numbers in the previous fiscal year when technology stocks were weaker.
The two companies, SoftBank and OpenAI, haven't confirmed any specific plans for the IPO. SB Energy's filing is kept confidential and specifics on valuation and sizes of offerings are not yet available.
