The Financial Times, as reported by The AI Insider, says SoftBank faces rising borrowing costs as it pursues the proposed fund. OpenAI is separately seeking another $30bn at a reported valuation of about $1.4tn, with funds including MGX in talks to anchor the round.

SoftBank shares fell as much as 7.3% in Tokyo on Friday amid concerns about OpenAI’s revenue growth, according to The AI Insider’s account. That adds a market reaction to a fundraising plan that remains unconfirmed, not a verdict on whether it will succeed.

The report also says SoftBank plans to list its robotics arm Roze in the US, while its SB Energy unit is preparing a Nasdaq listing. SB Energy is building an 8.8-gigawatt data centre in Ohio, giving the proposed AI push a sizeable infrastructure companion, and a sizeable financing question.
