AI company Anthropic announces IPO, expected as early as November

Anthropic announced that it had filed S-1 with the US Securities and Exchange Commission (SEC) for an initial public offering on Nasdaq, marking a significant step for artificial intelligence companies.

IPO Filing Details

A Monday S-1 filing with the SEC suggested that 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 company disclosed more than $16 billion in revenue for the first half of 2026 and an $80 billion net loss over the same period.

Background and Valuation

Anthropic was founded in 2021 by many former executives of AI company OpenAI.

Reports have suggested that the company could raise up to $100 billion for an IPO, giving it a $2 trillion valuation.

OpenAI 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.

The company behind the AI assistant Claude reported holding more than $112 billion in cash and cash equivalents, along with $19 billion in short-term investments, as of June 30.
