OpenAI Delays 2026 IPO to 2027, Insists on $1 Trillion Valuation; Anthropic Files at $96.5B

According to New York Times, OpenAI filed S-1 documents on June 8 but is considering delaying its IPO to 2027 to maintain CEO Sam Altman's $1 trillion valuation target. The company has not launched investor roadshows or tested market pricing, with insiders confirming that early discussions indicated "this could take more time."

Meanwhile, Anthropic submitted a confidential S-1 filing on June 1 with a $96.5 billion valuation—over $10 billion higher than OpenAI's previous private round—and may list before OpenAI. Market reaction has been swift: SoftBank shares fell over 12% amid concerns about its $65 billion planned OpenAI investment, while memory chipmaker Kioxia declined 12% as AI infrastructure spending expectations were reset.
