SoftBank Turns to an $11 Billion-Plus Bond Sale for Its OpenAI Bet

SoftBank launched $10 billion of dollar-denominated senior unsecured notes and €1 billion of euro-denominated notes to fund its investment in OpenAI. [3] The proceeds will finance a $10 billion payment for the third tranche of its follow-on OpenAI investment, expected to close on October 1. [3] The dollar notes have 3.5-year, 5.5-year and 7.5-year maturities, while the euro notes have 4-year and 6-year maturities. [3] The new bonds will also cancel a previously secured $10 billion bridge loan facility. [3]

Inflation-adjusted US spending on information-processing equipment, including data centers and computer hardware, now exceeds residential investment. [2] Bureau of Economic Analysis data put that equipment spending at $752 billion in the second quarter, following a 51% rise from early 2021. [2] S&P Global estimated that capital expenditures by Alphabet, Amazon, Microsoft, Meta, Oracle and SpaceX will exceed $1.3 trillion in 2027. [2]

SoftBank is replacing short-term bridge financing with unsecured debt spread across several currencies and maturities, tying its capital structure more directly to its OpenAI commitment. The transaction sits alongside a broader expansion in computing investment: information-processing equipment already exceeds US residential investment, while Alphabet, Amazon, Microsoft, Meta, Oracle and SpaceX are projected to lift combined capital expenditure again. That comparison shows OpenAI financing and hyperscaler infrastructure spending drawing from different funding channels while supporting the same expansion in AI capacity. What the sources don't address: how OpenAI’s performance or SoftBank’s future borrowing costs could affect repayment of the new bonds.
