Anthropic has filed a registration statement with the United States Securities and Exchange Commission on 26 October 2026 for an initial public offering.
The artificial intelligence company plans to list its Class A shares on the Nasdaq under the ticker symbol ANT.
Reports indicate the offering could raise as much as one hundred billion United States dollars, which would make it the largest initial public offering in history.
The company is expected to go public in November 2026, potentially the week of 16 November.
Analysts project a valuation of between one point five trillion and two trillion United States dollars once shares begin trading.
Anthropic reported revenue of sixteen point three billion United States dollars in the first half of 2026, up more than thirteen hundred per cent from the same period a year earlier.
The firm still recorded a large net loss for the half-year, driven largely by accounting adjustments related to financing agreements.
Opportunities and Risks Outlined
In the prospectus, Anthropic’s co-founders described artificial intelligence as one of the most consequential technologies in human history.
They highlighted potential benefits including higher productivity across the economy, advances in scientific research, and possible contributions to curing major diseases such as cancer.
The filing also detailed significant risks, including the possibility that advanced systems could develop self-preserving behaviours, resist shutdown, or produce outputs resembling coercion or blackmail.
Anthropic was founded in 2021 by researchers who left OpenAI over differences on safety and governance.
Its seven co-founders will retain majority voting control through a special share class after the listing.
The company has committed hundreds of billions of dollars in long-term computing contracts with major cloud providers.
Goldman Sachs and Morgan Stanley are leading the group of underwriters for the offering.
The filing marks a major test of investor appetite for pure-play artificial intelligence companies after years of rapid private funding.
Market observers note that the scale of the planned raise and the explicit discussion of existential risks make this one of the most closely watched public offerings of the year.
