Anthropic, PBC (P-ANTH) advanced on June 1, 2026, by confidentially filing a draft S-1 registration statement with the U.S. Securities and Exchange Commission for a proposed initial public offering. The company said timing and offering terms will depend on market conditions and the SEC review.
Confidential S-1 Filing and IPO Conditions
Anthropic submitted the draft registration statement on Form S-1 to the SEC, marking a key step toward going public. The company emphasized that the IPO remains optional following SEC review and that the timing will depend on market conditions and other factors. The filing does not specify the number of shares to be offered or the price, nor does it include a public prospectus, pricing range, or offering size.
Valuation, Market Interest, and AI IPO Context
Secondary reports placed Anthropic’s valuation at $965 billion after a $65 billion private financing round, which investors described as greatly oversubscribed. These figures have raised expectations for a major public offering and positioned Anthropic among large-cap AI companies. Secondary accounts also estimate the company is tracking toward an annual revenue run rate between $47 billion and $50 billion.
The confidential filing, combined with the scale of the recent financing, has drawn public-market attention to whether and when a leading AI company will test investor demand. This filing comes amid a broader wave of anticipated AI-related IPOs, with several large private AI firms preparing for public listings.
