SoftBank planned to sell $10 billion of dollar bonds and €1 billion of euro bonds to help finance its OpenAI investment. Early indications of interest exceeded $20 billion, but those were preliminary orders, not a final allocation. 13

Deal and use of proceeds

• The bonds are senior unsecured and junk-rated. The dollar portion was divided into 3½-, 5½- and 7½-year maturities; the euro portion was also to be issued in multiple maturities. The sale was expected to price on September 24 and settle on September 29. 14
• Proceeds were intended to cover a $10 billion OpenAI investment payment and reduce SoftBank’s reliance on bridge financing. SoftBank had a $40 billion bridge facility for its 2026 commitments that was due to be repaid or refinanced by March 2027; selling longer-term bonds would ease, but not necessarily eliminate, that refinancing obligation. 12
• At the planned size, it would rank among the largest Asia-Pacific corporate bond sales and be a record high-yield sale for an issuer from the region. A September 24 report says SoftBank issued $11.1 billion, so the planned size and the subsequently reported issued amount should not be treated as identical. 15

What the borrowing signals

• SoftBank had already raised $1.5 billion and €1.75 billion in bonds in April 2026, partly to repay bridge borrowing. The new sale therefore continued a shift from short-term financing toward longer-term debt. 1
• Strong early demand shows investors were willing to lend, not that they regarded the AI investment as low-risk. Reports described prospective yields reaching roughly 9%–10% on some dollar maturities—substantial borrowing costs consistent with concern about leverage and repayment risk. 23
• Insufficient evidence in the available results establishes precise credit-rating grades or credit-default-swap costs, so their levels—and any claimed change in default-insurance pricing—cannot be stated reliably here.
