Anthropic said on Monday that it has confidentially filed for a U.S. initial public offering, a procedural step that positions the company to potentially list on public markets. The company did not provide details on the size or terms of the planned offering.
The filing arrives after a late-May funding round in which Anthropic raised $65 billion at a post-money valuation of $965 billion, a level that places it ahead of rival OpenAI on that metric. The company’s valuation has more than doubled since February, when it had raised $30 billion at a valuation of $380 billion.
Market observers see the confidential filing as a high-stakes signal for Wall Street’s broader enthusiasm for artificial intelligence. The move will test whether investor demand can meet the elevated expectations that have propelled AI-focused firms to some of the market’s richest valuations. Anthropic and OpenAI have been prominent faces of an AI-driven shift that has altered corporate strategies, intensified global competition for computing capacity and talent, and influenced investment flows.
The step toward a public listing also comes amid other blockbuster transactions in the pipeline. SpaceX is pursuing what has been described as a mega-IPO, seeking a $75 billion offering at a $1.75 trillion valuation, a deal that has drawn attention for its potential to set new benchmarks in the market.
Reports indicate that OpenAI is also preparing to submit a confidential filing for a U.S. IPO in the coming weeks, according to a person familiar with the matter, adding to expectations of multiple high-profile technology listings ahead.
Anthropic’s recent funding and its confidential filing underscore the rapid revaluation of AI-linked businesses in private markets and illustrate the pressure on public markets to absorb large, highly valued entrants. For investors and market participants, the next phases of these filings will provide clearer signals about how the public capital markets will price and allocate capital to major AI companies.
Contextual note: The company has not revealed offering specifics and the timing and size of any public offering remain undisclosed.
