Anthropic filed confidentially for an initial public offering, according to corroborated reports from multiple news sources. The company, known for developing the Claude chatbot, submitted a confidential draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission on June 1, 2026, according to Bluesky. Anthropic is valued at close to $965 billion, as reported by Western outlets. Other sources, including India-based outlets, state that Anthropic is preparing for a potential $1 trillion IPO, though it is unclear whether this reflects current valuation or an aspirational target. Anthropic plans to list on the U.S. stock market, according to the BBC, and could make its market debut by the end of the year, as reported by France24. The U.S. government has twice blacklisted Anthropic's flagship products, and the U.S. Commerce Department has issued orders barring foreign nationals from using Anthropic's AI models, according to the Times of India. The Department of War has migrated away from Anthropic's technology, the same source reported.
