Anthropic Files for IPO, Joins AI Race to Public Markets
6 verified1 unconfirmed1 contested
Anthropic, the developer of the Claude chatbot, announced Monday that it has confidentially filed paperwork with the U.S. Securities and Exchange Commission for an initial public offering. The company said it has not yet set the number of shares or the price range. The filing follows a recent funding round that valued Anthropic at $965 billion, surpassing rival OpenAI’s $852 billion valuation. The IPO will proceed after the SEC completes its review, subject to market conditions. Anthropic joins SpaceX and OpenAI, which are both expected to go public later this year. The move signals a wave of major tech listings after a relatively dormant IPO market.
What’s verified
Anthropic confidentially filed a draft registration statement (Form S-1) with the SEC on June 1, 2026.
The number of shares and price have not been determined.
The IPO will go forward after the SEC review concludes, depending on market conditions.
Last week, Anthropic announced a $65 billion funding round that pushed its valuation to $965 billion.
Anthropic’s valuation now exceeds OpenAI’s $852 billion valuation reported in March.
SpaceX and OpenAI are also expected to file for IPOs later this year.
Where accounts differ
Accounts of SpaceX’s valuation differ. One source places it at about $1.75 trillion, while another reports it at $1.25 trillion after merging with Elon Musk’s xAI in February.
Not yet confirmed
A single source reported that Anthropic’s annualized revenue has reached $47 billion. That source also stated that Anthropic recently launched a new AI model called Claude Opus 4.8. Another source reported that Anthropic expects to go public as early as fall 2026, and that the company spent $1.6 million on lobbying in the first quarter of 2026 and is involved in a lawsuit against the Trump administration over Pentagon use of its AI. These details have not been confirmed by other sources.
