Shares of SoftBank slid nearly 13% on Friday in Tokyo after the New York Times reported that OpenAI — in which the Japan group holds a 13% stake — could delay its initial public offering until next year. Citing three sources, the report said OpenAI advisers are urging CEO Sam Altman to delay the IPO, following poor aftermarket trading in SpaceX shares. Altman won’t consider anything less than a $1 trillion valuation for the startup, but his advisers worry retail investors may now have less of an appetite for the ChatGPT maker. Earlier this month, OpenAI said it filed a confidential version of its draft IPO paperwork with the SEC. Apple shares dropped 6% as the company raised prices of some MacBooks and iPads due to rising component costs amid the AI boom, and the Nasdaq Composite logged its fourth day of losses. Anthropic, which announced earlier this month it had confidentially filed for its own listing, was valued in May at $965 billion, while OpenAI’s latest valuation, in March, was $852 billion.
