Anthropic filed a Form S-1 with the SEC on October 26 for a proposed initial public offering of Class A common stock. The company plans to list on the Nasdaq Global Select Market under the symbol "ANT", with Goldman Sachs and Morgan Stanley named for the preliminary prospectus. The share count and price range have not been set.
The filing shows revenue of $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier. As of September 30, more than 11,900 customers spent at least $100,000 a year, over 1,900 spent $1 million or more, and about 250 spent $10 million or more. Net revenue retention was about 900% at the end of Q3.
Why it matters: it is the first detailed look at the finances of a leading AI lab ahead of what could be one of the largest tech listings. Bloomberg reports an $80.7 billion net loss for the half, and the WSJ says the company is reportedly aiming to list the week of November 16.
