$40 billion. As a loan. For a single investment. If you thought the AI industry had peaked — SoftBank says: we’re just getting started.
The numbers
SoftBank has secured a $40 billion bridge loan to fund its $30 billion stake in OpenAI. The loan was arranged by JPMorgan Chase, Goldman Sachs, Mizuho, Sumitomo Mitsui, and MUFG. This brings SoftBank’s total investment in OpenAI to over $60 billion.
This isn’t a normal investment anymore. This is an existential bet.
Why a 12-month term?
Here’s the most interesting part: the loan has a term of just 12 months. That means it must be repaid or refinanced by spring 2027. Analysts and bankers see this as a strong signal that OpenAI’s long-anticipated IPO could indeed happen later this year.
The logic: if OpenAI goes public, SoftBank can partially liquidate its shares and pay back the loan. The lenders seem to believe in that scenario — otherwise they wouldn’t have extended this amount unsecured.
Market reaction
The stock market was less enthusiastic. SoftBank shares dropped sharply after the announcement. Investors are concerned about the sheer size of this debt-fueled bet. S&P had already downgraded the credit outlook earlier in March.
My take
Masayoshi Son is famous for his all-in bets — sometimes he wins big (Alibaba), sometimes he loses spectacularly (WeWork). This OpenAI bet is the biggest of his career. If the IPO comes and goes well, he’ll be celebrated as a visionary. If not, SoftBank has a problem that’s unusually large even by Japanese corporate standards.
For OpenAI itself, this is yet another sign: expectations are astronomical. With an $850 billion valuation, ChatGPT now really needs to become the productivity platform they’ve been promising.
