SoftBank Launches $11 Billion Junk-Bond Offering to Finance OpenAI Investment
By Drooid · · How we work
Core Deal Overview
SoftBank Group Corp. will issue senior unsecured notes totaling more than $11 billion—$10 billion in dollars and €1 billion in euros. Proceeds will fund SoftBank’s $10 billion payment for the third tranche of its OpenAI investment and general corporate purposes.
Background and Financing Context
SoftBank’s commitment to OpenAI now exceeds $64 billion. To meet these obligations, the conglomerate has repeatedly turned to debt markets, including a $40 billion bridge loan in March (partially repaid), a $10 billion bridge loan earlier this year (repaid in August), and an $11.87 billion loan later in the year. It has also expanded a margin loan backed by Arm Holdings to $25 billion and added a $450 million extension to a $6.5 billion credit line.
Deal Structure and Terms
- Dollar notes: $10 billion in three tranches (3.5, 5.5, 7.5-year maturities).
- Euro notes: €1 billion in two tranches (4 and 6-year maturities).
- Lead arrangers: Citigroup and JPMorgan (dollar); JPMorgan, Goldman Sachs and Deutsche Bank (euro). Additional coordinators include Goldman Sachs and Morgan Stanley.
- Rating and yield: BB+ (S&P), with the 2031 dollar bond yielding 8.2%, up from 6.7% in January.
Official Statements & Responses
The term sheet released on September 21 states the issuance will replace a previously secured $10 billion bridge loan and that pricing is set for September 24, with settlement on September 29. SoftBank declined comment, citing a holiday in Japan.
Market Reaction and Risk Factors
Higher borrowing costs have pushed yields up, while AI-safety concerns have raised the cost of insuring SoftBank’s debt, with credit-default swaps at a three-year high. The same concerns contributed to a sell-off on September 14, when the Philadelphia Semiconductor Index fell 5.2% and shares of Nvidia, AMD and Micron declined.
Why It Matters
The offering is one of the largest junk-bond sales by a single non-distressed issuer in 2026. It lets SoftBank continue its AI investment strategy without adding more bridge-loan exposure, underscoring the reliance of tech investors on high-yield financing amid tighter credit conditions.
Timeline
- September 21: Term sheet disclosed bond structure and use of proceeds.
- September 24: Pricing of the notes.
- September 29: Settlement of the issuance.
- October 1: Expected closing of the $10 billion OpenAI tranche payment.
What’s Next
If pricing proceeds as planned, the bonds will settle on September 29, after which SoftBank will complete the $10 billion OpenAI payment on October 1. The market will watch the impact on SoftBank’s credit profile and investor sentiment toward AI-related financing.
