SoftBank Initiates Massive $11 Billion High-Yield Bond Sale to Fuel AI Ventures

SoftBank Group, helmed by billionaire Masayoshi Son, has kicked off one of the largest corporate high-yield bond offerings ever executed, tapping into debt investor capital to bankroll its sweeping investments in artificial intelligence.

As one of the world's foremost AI investors, SoftBank has begun marketing the multi-tranche bond deal to investors, with pricing discussions for the US dollar-denominated portion currently underway. According to a source familiar with the matter, who requested anonymity because the details are not public, the group aims to raise more than $11 billion in equivalent funds through this issuance, comprising $10 billion in US dollar bonds and roughly €1 billion in euro-denominated notes.

This offering represents the latest in a series of frequent forays into the debt markets by SoftBank this year, as it seeks to finance its nearly $65 billion investment commitment to OpenAI, the creator of ChatGPT, while also securing capital for additional acquisitions in the sector. These moves position SoftBank as a central player in the growing wave of debt-financed AI expansion.

At a time when the transformative potential of artificial intelligence has become a focal point for global markets, concerns over the industry's safety standards continue to mount. SoftBank is not alone in turning to the debt market for funding. According to a recent analysis from credit strategists at Goldman Sachs Group, global AI-related debt issuance in 2026 has already surpassed $575 billion.

Son has previously downplayed worries about the risks associated with AI infrastructure spending, stating earlier this year that he expects AI-related industries to account for 20% of global economic output by 2040, equivalent to approximately $46 trillion. However, the surge of AI financing across global financial markets has left some bond investors feeling uneasy. They worry that if AI fails to deliver returns commensurate with the massive investments made by its biggest backers, the ballooning debt load could leave a heavy toll on the markets.
