Anthropic, the California-based artificial intelligence company behind the Claude chatbot, has confidentially filed for a U.S. initial public offering, potentially setting up one of the most closely watched market debuts in recent years.
The company did not disclose the proposed size, price range or timing of the offering. Its filing with the U.S. Securities and Exchange Commission allows it to prepare for an IPO while keeping financial details private until later in the process.
Anthropic’s move comes as investor interest in artificial intelligence remains high. The company was recently valued at $965 billion US after raising $65 billion US in funding, more than doubling its valuation from earlier this year. Its backers include major technology and financial investors such as Blackstone, Brookfield, General Catalyst, GIC and Insight Partners.
The filing also places Anthropic ahead of OpenAI, which has reportedly been preparing for its own potential IPO. OpenAI CEO Sam Altman has said the company will go public when it makes sense. Analysts say Anthropic’s decision to file first could give it an early advantage in shaping how public investors assess fast-growing AI companies, though it may also expose the company first to scrutiny over its finances and business model.
The broader IPO market has strengthened recently, with global listings raising $87.5 billion US through late May, the strongest year-to-date total since 2021. Anthropic’s filing follows reports that SpaceX is also preparing a major public offering that could value the company at $1.75 trillion US.
Market observers say the potential listings of Anthropic, OpenAI and SpaceX could place significant demands on investor capital. If Anthropic goes public at close to its current valuation, it would rank among the largest companies in the S&P 500 and become a major test of whether enthusiasm for artificial intelligence can continue in public markets.
