SoftBank Group Corp. is reportedly in talks to make an additional investment of up to $30 billion in OpenAI, according to The Wall Street Journal and Reuters.

The potential deal would further deepen SoftBank’s financial backing of the ChatGPT developer and reflects CEO Masayoshi Son’s ambition to position the conglomerate at the center of the global artificial intelligence boom.

OpenAI is currently seeking fresh capital as part of a major fundraising effort, with ambitions to raise as much as $100 billion.

If successful, the round could value the company at a staggering $830 billion, underscoring investor confidence in OpenAI’s expanding influence across AI applications and infrastructure.

Masayoshi Son’s AI-Centric Strategy

The prospective investment aligns with Son’s broader vision to embed artificial intelligence across all devices and technologies. To support this strategy, SoftBank has been actively reshaping its portfolio, divesting from several high-profile assets to free up capital.

These moves include selling its stake in Nvidia Corp. and pausing acquisition talks with U.S. data center operator Switch Inc.

SoftBank is already a significant OpenAI stakeholder, having reportedly injected $22.5 billion last month to build an 11% stake in the company.

The group has also accelerated AI-focused acquisitions over the past year, including the $6.5 billion purchase of U.S. chip designer Ampere Computing and a $5.4 billion deal for ABB Ltd.’s robotics unit.

Financial Risks and Market Concerns

Despite being an early proponent of artificial intelligence, SoftBank has largely missed out on the global race to develop core AI hardware such as semiconductors and server infrastructure.

Its recent investment surge, combined with a decline in the value of Arm shares late last year, has raised concerns about the group’s financial resilience.

To fund its aggressive expansion, SoftBank has sold down shares in T-Mobile US, exited its Nvidia position entirely, and increased margin loans secured against its Arm holdings.

These developments prompted S&P Global Ratings earlier this month to flag potential risks to the company’s credit profile, highlighting the delicate balance between Son’s bold AI ambitions and SoftBank’s financial stability.
