Some existing shareholders in Anthropic, along with prospective participants in its planned initial public offering (IPO), are now working with a company valuation of about $1.5 trillion, according to a report published by COINOTAG on October 16, 2026. That figure sits below the roughly $2 trillion valuation the same investors had previously pencilled in for the listing, which is expected to take place in November.

The revised expectations were described by four people familiar with the matter. The available report did not detail the reasons investors scaled back their valuation assumptions, and it did not specify the size of the offering or a target price range — details that are typically finalized only as a listing approaches.

A company valued at roughly $1.5 trillion would stand among the most valuable publicly traded firms in the world, and public listings of that scale are rare: Saudi Aramco's 2019 IPO, priced at a valuation of about $1.7 trillion, remains the only comparable precedent. Against that backdrop, the pricing of Anthropic's offering serves as a potential reference point for how public markets value leading artificial intelligence developers. Anthropic is a San Francisco-based artificial intelligence safety and research company known for developing the Claude family of AI assistants, which compete in a market alongside systems from OpenAI, Google and other major AI labs.

The company was founded in 2021 by former OpenAI researchers, including chief executive officer Dario Amodei and president Daniela Amodei, and counts Amazon and Google among its most prominent backers.

With the listing expected in November, the roughly $1.5 trillion figure remains a working assumption among shareholders and prospective participants rather than a set price; the final valuation will be established through the IPO pricing process. Whether that figure holds through pricing, and how the offering is ultimately sized, are among the details likely to draw attention ahead of the debut.
