SoftBank is tapping global debt markets with a bond offering exceeding $11 billion as the Japanese technology investor prepares for another substantial payment related to its OpenAI partnership.
The investment firm is marketing $10 billion in senior unsecured notes denominated in U.S. dollars alongside ā¬1 billion (approximately $1.15 billion) in euro-denominated securities.
The capital raised will primarily support a $10 billion payment associated with the third installment of SoftBank’s additional investment in OpenAI.
This transaction is scheduled to finalize on October 1.
Debt Markets Finance AI Ambitions
The U.S. dollar notes feature staggered maturities spanning 3.5 years, 5.5 years, and 7.5 years.
The euro-denominated bonds include four-year and six-year maturity options.
Pricing for the offering is anticipated on September 24, with settlement expected on September 29.
SoftBank previously secured a $10 billion bridge financing arrangement to support its OpenAI obligations.
According to the offering documents, the newly raised bond capital will retire that temporary credit facility.
Any excess funds will be allocated toward general corporate requirements.
Should the transaction complete at its targeted size, it would establish a record as the largest non-financial corporate bond issuance ever in the Asia-Pacific and Japan regions, based on LSEG data referenced by Reuters.
The deal would also secure a position among the top 20 largest corporate bond transactions worldwide in 2024.
Credit Rating Agency Assigns BB+ Grade
Fitch Ratings designated the proposed securities with a BB+ rating.
The agency noted that SoftBank’s debt levels are projected to climb as the company funds committed investment obligations.
Nevertheless, Fitch indicated that SoftBank should maintain sufficient liquidity and ongoing access to financial markets.
Citigroup serves as lead bookrunner for the dollar-denominated securities.
JPMorgan leads the euro portion of the offering.
Citigroup, Goldman Sachs, JPMorgan, and Morgan Stanley function as joint global coordinators for the dollar notes.
JPMorgan, Deutsche Bank, and Goldman Sachs coordinate the euro issuance.
AI Investment Takes Center Stage in Corporate Strategy
OpenAI has emerged as a cornerstone of SoftBank CEO Masayoshi Son’s artificial intelligence vision.
SoftBank has pledged tens of billions of dollars to the AI developer as it expands its presence in generative AI technologies and supporting infrastructure.
This latest financing underscores the substantial capital requirements necessary to sustain such a strategic position.
OpenAI continues to allocate significant resources toward computing power and infrastructure development as it scales its AI models and platform offerings.
This capital intensity has elevated the significance of major external investors like SoftBank.
The bond issuance also follows statements from OpenAI CEO Sam Altman indicating the company has no intentions to pursue an IPO in 2026.
Consequently, SoftBank’s investment continues as a stake in a privately held enterprise rather than a company approaching public markets.
SoftBank’s Vision Fund has already realized valuation increases across portions of its AI-focused portfolio.
Currently, the company is leveraging international bond markets to finance the next phase of its OpenAI partnership, with the $10 billion payment due on October 1.
