The largest artificial intelligence companies are heading for the stock market, and Anthropic, the US developer of the Claude models, is moving first with an initial public offering that could rank among the biggest in history. On Tuesday, 10 November 2026, the company filed an updated prospectus with the US Securities and Exchange Commission setting a price range for its shares, and began marketing the offering to investors.
What is officially known so far:
- 825 million Class A shares offered at 70 to 78 dollars each, with an option for underwriters to buy up to 123.75 million more.
- Expected proceeds of 57.75 billion to 64.35 billion dollars.
- A fully diluted valuation of just over 1.3 trillion dollars at the midpoint of the range and about 1.404 trillion dollars at the top.
- A planned listing on the Nasdaq under the symbol ANT, with trading expected to start around 19 November, CNBC reported, citing sources.
- A parallel private placement of 26 billion dollars to a group of technology companies, among them Google and Nvidia.
- Goldman Sachs and Morgan Stanley are among the underwriters.
The filing also showed revenue of 17 billion dollars in the third quarter and an annualised revenue run rate of 81 billion dollars at the end of October. The offering comes as AI stocks have pulled back, and the target valuation is below earlier reports of 2 trillion dollars. The final price will be set at pricing, shortly before the listing.
