Anthropic, the San Francisco-based artificial intelligence company known for its Claude assistant, has filed an S-1 registration statement with the United States Securities and Exchange Commission (SEC), formally initiating the process for an initial public offering on the Nasdaq stock exchange. An S-1 is the registration document US companies must file with the SEC before shares can be offered to the public, and it opens a review period in which the regulator examines the company's financial disclosures and risk factors. The move marks a significant step for AI companies seeking public listings.
A Monday S-1 filing with the regulator suggested Anthropic could be aiming for a mid-November IPO, listing its Class A common stock on the Nasdaq Global Select Market under the ticker symbol ANT. The registration was submitted under the name Anthropic PBC, reflecting the company's status as a public benefit corporation — a for-profit structure that allows directors to weigh a public benefit mission alongside shareholder returns. Under the standard process, the filing is followed by SEC review, after which the company would set a price range and market the offering to institutional investors ahead of its trading debut.
The filing disclosed more than $16 billion in revenue for the first half of 2026, alongside an $80 billion net loss over the same period. As of June 30, the company reported holding more than $112 billion in cash and cash equivalents, along with $19 billion in short-term investments. Disclosures of this kind are typically the first detailed public view of a private company's financials ahead of a listing.
Anthropic was founded in 2021 by former executives of AI company OpenAI, including CEO Dario Amodei. Reports have suggested the company could raise up to $100 billion in the offering, which would give it a $2 trillion valuation — a scale that would place it among the largest public listings on record. Final terms, including the number of shares offered and the offering price, would be set closer to the listing date.
OpenAI, for its part, has already delayed its own IPO plans, with CEO Sam Altman reportedly saying in September that 2026 was an "ill-advised moment" to pursue a public offering. On the current trajectory, Anthropic would be the first of the two AI rivals to reach the public markets.
