What happened

SoftBank (9984.T) stock rose 13.9% to ¥3,872 on Tuesday as Asian tech shares rebounded, even though the company reported a ¥1.1 trillion quarterly net loss from AI costs. It was SoftBank's first loss in two years. A year earlier it made a ¥2.5 trillion profit. SoftBank paid up front for power equipment for US AI data centers, then took a $3.7 billion hit when plans changed, and its borrowing costs more than doubled to ¥462 billion. Sales rose 16% to ¥2.2 trillion.

Why it matters

SoftBank is one of the biggest backers of OpenAI, the maker of ChatGPT, and its results show how costly the AI boom is to fund. It has invested $64.6 billion for a stake of about 13%, which the company values at roughly $99.6 billion on paper before the latest $10 billion top-up. To keep paying for AI projects, it raised a record $56.5 billion in the quarter from loans and asset sales.
