Anthropic files confidentially for IPO in the US

North American artificial intelligence company Anthropic, creator of the Claude chatbot, said on Monday that it has filed confidentially for an initial public offering in the United States.
Anthropic did not disclose the size or terms of the offering. The company raised $65 billion in late May, giving it a market valuation of $965 billion, putting it ahead of rival OpenAI.
Anthropic's valuation more than doubled from $380 billion in February, when it raised $30 billion in a funding round.
The company's rapid rise in early 2026 rattled markets, triggering sharp sell-offs in shares of software and information technology companies as investors fear that its increasingly autonomous AI tools could upend traditional business models and accelerate disruption across industries.
OpenAI is also preparing to file confidentially for an IPO in the US in the coming weeks, a source familiar with the matter told Reuters in late May.
As a series of giant stock listings approach the capital markets, companies from SpaceX to AI giants are competing for a finite amount of investor capital.
A Anthropic's listing will represent one of the most important stock market debuts in recent years, potentially reshaping benchmarks, investor flows and the broader narrative driving U.S. stocks.
With a valuation approaching $1 trillion, Anthropic will enter the top tier of the S&P 500 index, alongside a handful of companies that dominate global equity markets.
