The Japanese conglomerate is borrowing heavily to expand its bet on OpenAI, and investors are buying into the plan for now.

Executive takeaway

SoftBank Group issued $11.1 billion in bonds to finance its investment in OpenAI, and its shares rose sharply in response.

SoftBank Group issued $11.1 billion in bonds on September 23 to fund a further investment in OpenAI, the ChatGPT maker. The bond sale is one of the largest debt raises SoftBank has done this year and signals how much capital the company is willing to commit to its artificial-intelligence bet. SoftBank shares surged the same day, according to two separate wire reports flagging the move, though neither cited a specific percentage gain. The rally suggests investors are, for now, reading the bond issuance as a sign of confidence in OpenAI's growth rather than a balance-sheet risk. What is unresolved is how SoftBank plans to service this new debt load if OpenAI's revenue growth slows, and whether ratings agencies will react to the added leverage. Neither question has been addressed in public SoftBank commentary so far.
What would change this view

This bullish reading would be undercut if a ratings agency downgrades SoftBank's debt following the $11.1 billion issuance, or if SoftBank's next earnings report shows the OpenAI stake being written down.
