SoftBank Strengthens Financing Efforts, Targets New AI Investment Cycle
Japan's SoftBank Group Corp. has once again completed a large-scale financing operation through international capital markets, showcasing its ambition in the global artificial intelligence investment wave. The group announced on Thursday that it successfully issued approximately $2.9 billion in hybrid subordinated bonds to support its "Stargate" AI program and global technology expansion.
The financing includes two tranches of dollar-denominated bonds and one tranche of euro bonds, raising $2 billion and €750 million (approximately $871 million) respectively. According to the prospectus, the long-term dollar bonds carry a coupon rate of 8.25%, and the euro bonds rate is 6.5%, indicating investors’ sustained interest in SoftBank bonds in a high-yield environment.
Strong Bond Demand, Active Participation from Overseas Investors
Despite SoftBank's credit rating still being classified as "junk-rated" by major rating agencies, this issuance was oversubscribed, reflecting international investors' recognition of its AI strategy potential. Market analysts believe the bonds' high coupons and SoftBank's influence in the global tech sector jointly drove the strong subscription demand.
A bond analyst at a London asset management firm noted: "The allure of SoftBank bonds lies in its diverse tech investment portfolio. Although credit risk remains high, its strategic position in the AI ecosystem entices investors to accept the risk for a higher yield."
"Stargate Plan" Becomes a Core Funding Destination
One of the primary uses of this financing is to support the "Stargate" plan spearheaded by Masayoshi Son. The plan aims to invest $50 billion in AI infrastructure, computing power centers, and AI startups over the next four years. Masayoshi Son recently emphasized at several public events that the AI revolution will be the "most significant technological turning point in human history," and SoftBank aims to be a key driver of this change.
According to insiders, SoftBank plans to allocate part of the funds to new AI projects under its Vision Fund and is also considering increasing indirect stakes in OpenAI, Anthropic, and other generative AI companies.
Global Financing Strategy Advances on Multiple Fronts
This year, SoftBank has entered the international capital markets for financing multiple times. In July alone, the company raised $4.2 billion through dollar and euro bond issuances. With this additional $2.9 billion raised, SoftBank’s overseas fundraising in just four months has exceeded $7 billion.
Meanwhile, SoftBank maintains an active financing pace in the domestic Japanese market. Statistics show that since 2025, the company has issued approximately 820 billion yen (around $5.4 billion) in bonds in Japan, making it the largest single-issuer of corporate bonds in the country. This demonstrates that SoftBank is balancing its funding sources through multiple channels to address global interest rate fluctuations and market liquidity challenges.
AI Investments Signal Transformation
SoftBank's accelerated financing pace also reflects a renewed shift in its business focus. Since selling off part of its Alibaba shares and experiencing declining returns from the Vision Fund, the group is redefining its growth curve through AI investments. Analysts believe Masayoshi Son is transforming SoftBank from a traditional investment holding company into a technology group driven primarily by AI.
Nomura Securities pointed out in its latest research report that SoftBank's capital allocation strategy in global AI infrastructure is showing economies of scale, especially in chip manufacturing, cloud computing, and generative AI applications. The report predicts that if the "Stargate Plan" progresses smoothly, SoftBank may regain a high-growth valuation within three years.
Market Prospects and Challenges Coexist
Although the successful financing has provided SoftBank with stronger financial reserves, high-yield bonds also mean a heavier financial burden. Analysts warn that if AI investment returns are delayed, the company’s debt repayment pressure will increase. Additionally, the international market’s interest rate environment remains unstable and the monetary policy directions in the US and Europe could affect future refinancing costs.
Nonetheless, Masayoshi Son is evidently confident in the long-term returns of AI investments. He stated at a financial report release: "AI is the wealth engine of the next decade. SoftBank’s goal is not short-term gains, but to lay the foundation for the future intelligent economy."
Conclusion: SoftBank's AI Bet Remains Ongoing
With this $2.9 billion financing in place, SoftBank has raised over $12 billion in the fiscal year 2025. Regardless of market fluctuations, Masayoshi Son’s strategic intent to bet on AI is becoming increasingly evident. From semiconductors to algorithmic platforms, from computing power centers to AI startup ecosystems, SoftBank's investment landscape is expanding comprehensively.
It is foreseeable that the future fortunes of the SoftBank Group will be closely aligned with the advancement of global AI technology. Masayoshi Son’s "AI gamble" is becoming one of the most watched technological stories in the global capital markets.
