SoftBank Shares Jump 8% as Data Center Unit SB Energy Advances IPO Plans

Shares of SoftBank Group Corp. (TYO:9984) surged on Tuesday, recovering a significant portion of the previous day's steep losses, as the company's data center unit, SB Energy, moved forward with its planned U.S. initial public offering.
IPO Progress Boosts Sentiment
Investor optimism was fueled by new details about the SB Energy listing. According to a filing cited by Reuters, the unit will sell $500 million in shares to Japanese investors as part of its U.S. debut. Previous reports have suggested SB Energy could seek a valuation as high as $50 billion.
The IPO prospectus, released in early September, highlights significant interest from major technology players, underscoring the high demand for data infrastructure driven by artificial intelligence. Key commitments disclosed include:
- A $1.5 billion investment from Nvidia through a private placement at the IPO price.
- Warrants held by OpenAI valued at approximately $5.5 billion.
A successful listing for SB Energy would represent a major windfall for SoftBank, providing fresh capital and crystallizing the value of its AI-related infrastructure investments.
AdRebound From Previous Session
Tuesday's rally marks a sharp reversal from Monday, when SoftBank's stock plummeted more than 11%. The sell-off was triggered by news that portfolio company OpenAI will not pursue an IPO in 2026, delaying a potentially lucrative exit for the Japanese investment conglomerate.
The conglomerate's shares had also been under pressure from broader market concerns regarding a potential slowdown in AI development and increased scrutiny over its safety.
Market Reaction
SoftBank Group finished the trading session up 8.1% at 6,314.0 yen. The stock was a standout performer, ranking among the top gainers on Japan's benchmark Nikkei 225 index, which closed up a modest 0.1%.
