Anthropic files IPO targeting up to one point five trillion valuation

Artificial intelligence developer Anthropic PBC has officially filed its S-1 prospectus with the United States Securities and Exchange Commission for an initial public offering. Fast Company reported that an investor roadshow could begin as soon as November 9 to generate interest in the company. The Verge reported that Anthropic plans to list its shares on the Nasdaq exchange using the ticker symbol ANT. [3][5][7]

The public filing offers a direct look into the economics of large AI developers. Fast Company reported that Anthropic is aiming for a targeted valuation of $1.5 trillion. Business Insider reported that Anthropic generated $11.6 billion in revenue, showing that artificial intelligence models can operate profitably at scale. [1][3]

The filing highlights an expanding cross-product ecosystem for business clients. According to TechCrunch, more than half of Anthropic's enterprise accounts spending at least $100,000 annually now use both the Claude platform and a first-party application. TechCrunch noted that this adoption rate rose from approximately 30 percent at the end of last year. [4]

The company previously submitted confidential paperwork to regulators on June 1, 2026, as noted in corporate history records. MarketWatch, CNBC, and the Financial Times reported that the extensive S-1 prospectus outlines both significant revenue growth opportunities and the operational risks associated with advancing artificial intelligence infrastructure.
