Anthropic is preparing for an initial public offering in November, according to The Wall Street Journal, which cited unnamed sources on Friday (Sept. 18). The timing is later than the October debut many investors had anticipated. The November date may allow Anthropic to report third-quarter financials, which are expected to be strong. The decision was made before recent debates about the pace of artificial intelligence development, the report noted. The timing could still change. An IPO could value Anthropic at approximately $2 trillion and raise up to $100 billion, exceeding SpaceX’s June record. Bloomberg also reported Friday, citing a paywalled New York Times article based on unnamed sources, that Anthropic is preparing for an IPO as soon as November and expects to debut within weeks. Anthropic’s revenue run rate reportedly surged from $9 billion at the end of 2025 to $65 billion at the end of July. This acceleration strengthens its IPO plans despite growing public concern about AI.
OpenAI CEO Sam Altman told Fortune on Sept. 11 that OpenAI’s IPO will not occur in 2026. Altman said OpenAI has long insisted it is in no rush to list. Concerns about AI safety mean that “right now would be an ill-advised moment to go public,” he added. Like Anthropic, OpenAI’s IPO could be one of the largest ever. Anthropic announced June 1 that it confidentially filed for an IPO, with timing dependent on market conditions and other factors. OpenAI said June 8 that it had submitted a confidential IPO filing and had not decided on timing. PYMNTS reported Thursday (Sept. 17) that experts say a potential frontier AI slowdown would not slow adoption of the technology. “Enterprises won’t stop adopting AI just because they don’t have new models to deploy,” Savvi AI CEO and Co-Founder Maya Mikhailov said.
