SoftBank Group is preparing to sell ¥1 trillion in retail bonds in Japan, roughly $6.3 billion, making it the largest bond issuance by any entity in the country’s history. The proceeds will fuel the company’s increasingly massive investment in OpenAI, which has now surpassed $60 billion in total commitments.
A funding machine running on overdrive
This isn’t even SoftBank’s first retail bond rodeo this year. It’s the third.
The company sold ¥418 billion in bonds in April, followed by another ¥260 billion tranche in June. Adding the new ¥1 trillion offering, SoftBank will have raised roughly ¥1.68 trillion from Japanese retail investors in 2026 alone.
Beyond the bond market, SoftBank has also arranged a $40 billion unsecured bridge loan maturing in March 2027. That facility supports both the OpenAI investments and related infrastructure development.
