SoftBank’s Strategic Bet on an OpenAI Public Offering

Japanese investment giant SoftBank has significantly increased its stake in artificial intelligence leader OpenAI, bringing its total holding to approximately 13%. This position, now valued at $64.6 billion, represents a calculated strategic move. Market observers interpret this aggressive investment as a direct wager on OpenAI conducting an initial public offering (IPO) by late 2026 or 2027, potentially at a valuation approaching $1 trillion.

Financing a Future Exit

To fund this latest expansion of its position, SoftBank secured a substantial $40 billion credit facility. The unsecured loan, which matures in March 2027, was arranged by a consortium of financial institutions including JPMorgan Chase, Goldman Sachs, and several Japanese banks. The timing of this debt instrument is notable, as its term aligns closely with the speculated timeline for a potential OpenAI listing, suggesting it is structured to bridge the period until a liquidity event.

Portfolio Performance and Market Headwinds

Amid this strategic positioning, SoftBank’s portfolio company Arm Holdings continues to deliver strong operational results. For its third fiscal quarter ending December 2025, Arm reported revenue of $1.24 billion, a 26% year-over-year increase. This growth was driven by a 27% surge in royalty revenue and a 25% gain in licensing revenue. The company’s technology remains central to the AI ecosystem, with over 70,000 businesses utilizing Arm-designed chips for artificial intelligence workloads.

Should investors sell immediately? Or is it worth buying SoftBank?

However, the broader market environment presents challenges. The Nasdaq Composite index has retreated 10.7% from its recent highs, pressured by geopolitical uncertainty and growing investor skepticism regarding the near-term profitability of massive AI capital expenditures. Despite this volatility, SoftBank appears committed to its long-term strategy.

Challenges in a Flagship Joint Venture

Not all of SoftBank’s ambitious AI initiatives are progressing smoothly. The firm is a partner in the “Stargate” project, a joint $500 billion venture with OpenAI and Oracle aimed at developing next-generation AI infrastructure. Reports indicate the collaboration has encountered difficulties, with disputes over control and operational responsibilities creating friction. As a result, OpenAI has reportedly abandoned plans to expand its primary data center site in Abilene. Microsoft has stepped in to assume responsibility for portions of the data center construction, though development continues at other selected locations.

Through these actions, SoftBank is systematically building a commanding stake in OpenAI. Should the AI firm proceed with a public listing, this investment is poised to become one of the largest single holdings within SoftBank’s extensive investment portfolio.
