Anthropic files for IPO at a near $1 trillion valuation

[Rough Reece]

Anthropic filed a confidential S-1 with the SEC on June 1, 2026, setting up what could be one of the biggest AI listings ever. The company recently raised $65 billion in a Series H round pushing its valuation to around $965 billion. Revenue run-rate reportedly hit $47 billion in May 2026, up from $9 billion at the end of 2025. Claude has also jumped to the top of app charts and is deeply embedded in Amazon Bedrock and enterprise workflows.

That revenue growth from $9B to $47B in under 6 months is almost impossible to comprehend. The enterprise adoption must be massive

Interesting that they are racing OpenAI to be first to list. Whichever one prices first sets the valuation comparable for the other

The PBC structure interacting with public shareholder rights is going to be the most interesting part of that S-1 to read

Nearly $1 trillion and they are still burning through capital on training runs. The IPO gives them permanent capital which changes the game

Claude hitting the number 1 spot on the Apple App Store earlier this year clearly helped push the commercial numbers

Competitors like xAI have to keep raising private rounds while Anthropic and OpenAI will have public stock to use for acquisitions. Big structural advantage
