Anthropic, developer of the Claude chatbot, confidentially filed a draft registration statement for an initial public offering on June 1, 2026. This filing moves the company ahead of chief rival OpenAI in the race to go public.

A recent Series H funding round valued Anthropic at $965 billion. The number of shares and price range remain undetermined pending SEC review and market conditions.

The listing serves as a pivotal test of investor appetite for the capital-intensive AI sector. This offering could reinvigorate the IPO market alongside expected listings from OpenAI and SpaceX.
