Anthropic files for IPO, could become one of the largest ever

The American AI company Anthropic, the maker of the Claude chatbot, confidentially submitted a draft registration statement (known as an S-1) to the US Securities and Exchange Commission (SEC) on Monday, June 1, 2026. It is the first step toward going public, meaning the company's shares can be bought and sold by anyone on a stock exchange.

The filing came about a week after Anthropic announced a $65 billion funding round that valued the company at $965 billion.

Anthropic says it may go public once the SEC has completed its review. How many shares will be offered, and at what price, has not been set. The timing depends on market conditions.

Big numbers, but differing estimates

According to the New York Times, as relayed by AI Weekly, the banks behind the IPO have told investors that an October listing could raise more than $100 billion. The valuation would then be close to $2 trillion. Crypto Briefing reports that the offering could raise $60-100 billion, and that Anthropic has reportedly chosen the Nasdaq exchange.

The figures are thus the banks' and the media's estimates, not an official number from Anthropic. No source has been found showing that a public prospectus has been filed, either.

Morgan Stanley, Goldman Sachs, JPMorgan and Citigroup are named as banks working on the IPO. The sources do not fully agree on which ones are leading it.

According to Crypto Briefing, Nvidia is considering investing $10 billion in the offering. This is a report and has not been confirmed by Anthropic. According to the same source, the goal is to complete the IPO before the US midterm elections in November.

Growing revenue and profit

According to Crypto Briefing and The Decoder, Anthropic's annualized run rate, meaning the annual revenue if the current pace continues, was over $65 billion at the end of July 2026. In May, the figure was $47 billion.

The Decoder, citing the Financial Times, reports that revenue in one quarter was $11.5 billion, 14 times as much as a year earlier. Anthropic says the company is posting a profit for the second quarter in a row.

The profit is calculated on an adjusted basis, excluding stock-based compensation, and the figure has not been independently verified. Gross margin is reported at over 80 percent, but without revenue-sharing costs with partners such as Amazon and the costs of training models. Search results also mention large net losses, with figures varying.

According to The Decoder and the Financial Times, Anthropic shared its documents only with selected investors instead of publishing the prospectus as planned. According to the New York Times, Anthropic expects its 2026 run rate to reach $100-120 billion by the end of the year.
