The move has further stoked concerns among some investors that the rally in artificial intelligence stocks was overdone.
But to help pay for those expensive investments, the company last month sold its entire $5.8 billion holdings in Nvidia, the chipmaker behind the A.I. boom, SoftBank said in its quarterly earnings report on Tuesday.
SoftBank’s enormous spending plans, including some $30 billion alone on OpenAI, come amid a flood of planned investments in artificial intelligence across the technology industry — including circular deals among the same companies. (Nvidia, for example, is committed to investing up to $100 billion in OpenAI, which in turn plans to buy an enormous slug of the chipmaker’s processors.)
