SoftBank Group has launched a jumbo bond sale exceeding $11 billion to help finance its planned investment in OpenAI. The offering consists of $10 billion of senior unsecured dollar notes and an additional €1 billion of euro-denominated notes, marking one of the most significant corporate bond financing exercises in the Asia Pacific and Japan market for a non-financial company if completed at the planned size. The proceeds from this jumbo bond sale are intended to fund the company’s $10 billion payment for the third tranche of its follow-on OpenAI investment. A portion of the funds raised will also be available for general corporate purposes.
Structure and Timeline of the Bond Offering
The dollar notes within this jumbo bond sale are structured across three maturity windows: 3-1/2 years, 5-1/2 years and 7-1/2 years. The euro-denominated tranche carries maturities of four years and six years. At current exchange rates, the total offering amounts to approximately $11.15 billion.
Fitch Ratings has assigned the proposed senior unsecured notes a BB+ rating. Fitch expects SoftBank’s debt levels to rise as the company continues to fund committed investments while retaining access to capital markets. The corporate bond financing effort also serves to replace a $10 billion bridge loan that SoftBank had previously secured to support the same OpenAI investment. By converting that short-term facility into longer-dated bonds through the capital markets debt route, the company is extending its financing horizon for this strategic commitment.
Broader Financing Activity Supporting the Investment
This jumbo bond sale forms part of a wider pattern of borrowing by SoftBank as it pursues its substantial financial commitment to OpenAI. The company has committed approximately $65 billion to OpenAI and has increasingly relied on debt instruments to support that exposure. In March, SoftBank entered into a $40 billion bridge financing arrangement for an additional OpenAI investment. It has since repaid $25.9 billion of that facility.
SoftBank has also expanded several other borrowing lines. A margin loan secured against shares in chip designer Arm Holdings was increased by $5 billion to $25 billion, while a separate credit line was expanded by $450 million to $6.5 billion. Apollo Global Management is reportedly in discussions to increase a loan to SoftBank by $3.6 billion to $9 billion. The company has also separately secured an $11.87 billion loan to help finance its OpenAI investment.
The scale of this jumbo bond sale underscores the depth of capital markets debt activity SoftBank is undertaking to deliver on its planned commitments. Citigroup and JPMorgan are serving as lead bookrunners on the corporate bond financing transaction. The offering has been launched but has not yet priced or settled, and the third tranche of the SoftBank OpenAI investment remains pending.
