SoftBank Group's credit risk has reached its highest level in nearly four years, driven by heavy borrowing to fund artificial intelligence investments and growing investor concern over the company's financing strategy.
Credit default swaps (CDS) tied to SoftBank have climbed to 380–400+ basis points, with spreads rising approximately 24% between June and October 2026. The cost of insuring SoftBank's debt against default now stands at roughly 4% annually of the protected amount. This marks the highest CDS level since 2022.
SoftBank's largest AI commitment is to OpenAI, totaling $64.6 billion—representing roughly 13% of the ChatGPT maker as of early October 2026. To finance this and other technology investments, SoftBank sold a record $11.1 billion in high-yield bonds on September 24, 2026, with coupons of 8.625%, 9.25%, and 9.75%—the highest described as historically steep. Beyond OpenAI, SoftBank has allocated $5.4 billion toward ABB's robotics business and $3.1 billion to DigitalBridge for data center expansion.
Rating agencies are monitoring the company closely. On September 11, 2026, Fitch assigned SoftBank its first-ever BB+ rating (one notch below investment grade) with a stable outlook, while flagging OpenAI exposure risks. S&P Global maintained a negative outlook on the company. SoftBank's stock price has fallen 38% since peaking in June 2026.
Investors cite concentration risk in SoftBank's portfolio, particularly around Arm Holdings and OpenAI, combined with reports of a potential large acquisition that could require additional financing. The company's heavy reliance on debt to fund private company stakes has raised questions about its capital structure and repayment capacity.
Why This Matters
SoftBank's elevated credit risk—measured by CDS spreads reaching 4-year highs and first-time sub-investment-grade rating from Fitch—signals rising market concern about the company's ability to service $64.6 billion in AI commitments funded by debt. The 38% stock decline since June, record high-yield bond issuance at 9.75% coupons, and negative outlook from S&P indicate investors are demanding higher compensation for refinancing and leverage risk. This directly affects SoftBank's cost of capital, investor sentiment in the AI financing sector, and potential constraints on future acquisition or investment capacity.
