SoftBank Group Corp. reported a $2.4 billion gain in its December quarter, primarily fueled by the rising valuation of its OpenAI investment. The Japanese conglomerate’s Vision Fund, which has invested roughly $40 billion in OpenAI, has seen its strategic bets on artificial intelligence pay off significantly.
Analysts say these gains reflect not only the performance of OpenAI but also SoftBank’s broader AI-focused portfolio, including stakes in chip designer Arm and companies specializing in robotics and autonomous vehicles.
Following these results, SoftBank’s shares climbed this week, reflecting investor confidence in the company’s long-term AI strategy. Market observers note that the Vision Fund’s aggressive approach is positioning SoftBank as a central figure in AI development on a global scale.
SoftBank’s investment gains tied to OpenAI have far exceeded earlier forecasts. Over the first nine months of the fiscal year, Vision Fund 2 logged $17 billion in gains from OpenAI alone. Vision Fund 2, fully funded by SoftBank itself after drawing no outside investors, managed this growth even following a record $32 billion loss for SoftBank Group in the prior fiscal year.

OpenAI’s $41 billion financing round included $30 billion from SoftBank Vision Fund 2, with co-investors contributing the remaining $11 billion. This financing supports AI infrastructure buildouts, including computing, data centers, and networking necessary to operate AI services at scale. The arrangement demonstrates SoftBank’s commitment to funding comprehensive AI ecosystems, rather than isolated projects.
Beyond OpenAI, SoftBank’s market performance has also benefited from an uptick in Arm’s stock price and solid results from the company’s telecom division. Investors have welcomed this combination, which signals both technological and operational strength. The dual gains reinforce confidence in SoftBank’s diversified approach, blending AI innovation with core business stability.
Additionally, SoftBank recently sold a $5.83 billion stake in NVIDIA and completed a $3.1 billion acquisition of DigitalBridge. These moves are consistent with a broader strategy of capital recycling and investing in high-potential AI and technology sectors.
SoftBank’s Vision Fund continues to back end-to-end AI solutions, spanning model development, infrastructure, and distribution. Reports indicate that part of the OpenAI funding is also allocated to Stargate, a joint AI infrastructure venture with Oracle.
These investments reflect a growing trend among global investors to build comprehensive AI stacks rather than funding isolated technology pieces.
Market experts suggest SoftBank’s strategic positioning could make it a leading force in AI for years to come. By combining financial backing, operational expertise, and partnerships with technology leaders, the company is aiming to shape both the AI industry and its own long-term growth trajectory.
SoftBank’s latest quarterly gains underscore the power of AI-focused investments in driving market performance. With OpenAI, Arm, and other technology bets, the company is leveraging its Vision Fund to establish itself as a central player in the rapidly expanding AI landscape. Investors are watching closely, as these moves could define SoftBank’s role in the next generation of technology-driven markets.
