5/13/2026, 11:12:15 AM
OpenAI Investment Drives SoftBank's FY 2025 Profit
SoftBank Group invested more than $30 billion in OpenAI, securing roughly an 11-13 percent ownership stake. The AI-lab’s February 2025 funding round, co-led by SoftBank, valued OpenAI at $852 billion, lifting SoftBank’s paper gains on the holding to about $45 billion for the fiscal year ended March. Those gains propelled the Vision Fund’s overall $46 billion yearly increase and helped SoftBank post a net profit of roughly 5 trillion yen for FY 2025.
AI Strategy and Prior Investments
The OpenAI commitment sits within a broader AI push that includes the 2024 acquisition of UK chip maker Graphcore (>$450 million injection) and participation in the $500 billion Stargate data-centre partnership with OpenAI and Oracle. SoftBank also plans $16 billion for Stargate infrastructure and $9 billion for the acquisitions of ABB Robotics and DigitalBridge in 2026. These moves aim to position SoftBank at the centre of AI hardware and robotics development.
Key Financial Figures
- OpenAI stake: ? 11 % (per TD Cowen) to 13 % (per SoftBank)
- Stake valuation: $80 billion at end-March (up from $54.4 billion in Dec)
- Total OpenAI commitment: > $60 billion, with $30 billion slated for 2026
- FY 2025 net profit: ~5 trillion yen (? $33 billion)
- Expected Q1-2026 profit: 236 billion yen (? $1.5 billion)
- Financing: $40 billion bridge loan secured in March; planned margin loan reduced after lender hesitation
- Share price: near 6,923 yen, with Nomura target 7,500 yen.
Official Statements & Responses
S&P Global Ratings revised SoftBank’s credit outlook to negative, citing deteriorating asset liquidity and portfolio quality due to the OpenAI exposure. SoftBank confirmed a $40 billion bridge loan to fund the stake and disclosed that a proposed margin loan backed by the same holding was scaled back after creditor caution. The group also announced plans to create and list a U.S. AI-robotics company, targeting a $100 billion valuation. Analysts at TD Cowen and Jefferies expect the OpenAI position to remain a primary earnings driver while monitoring financing capacity.
Criticism & Opposition
Market observers highlight concentration risk, noting that SoftBank’s earnings now hinge on a single private asset. Comparisons to the failed WeWork investment underscore concerns about debt sustainability and potential credit strain. Analysts stress that continued borrowing against illiquid private shares could amplify credit risk if OpenAI’s valuation fluctuates.
Conflicting Reports & Gaps
- Ownership percentage varies between 13 % (SoftBank) and 11 % (TD Cowen).
- Stake valuation is reported as $45 billion in gains versus $80 billion market value.
- Total OpenAI commitment is described as “more than $60 billion” versus “an additional $30 billion in 2026.”
- Timing of the planned AI-robotics spin-off is cited as “as early as this year” and also as an undefined future listing.
- Details on the ultimate source of funding for the $25 billion of 2026 AI investments remain unspecified.

Outlook and Upcoming Developments
SoftBank’s next earnings release (Wednesday) will reveal whether the $40 billion bridge loan and reduced margin loan suffice to fund the remaining $30 billion OpenAI infusion and other AI projects. Analysts will watch for updates on the planned AI-robotics spin-off, the timing of OpenAI’s anticipated public listing in late 2026/early 2027, and any further shifts in credit ratings as the concentration risk evolves.
