Anthropic files to sell stock as ANT

Anthropic, the company behind the Claude chat tool, filed papers with the U.S. stock market watchdog on the 26th of October 2026.

The filing, called Form S-1, is the step a private firm takes when it wants to sell shares to the public for the first time. That first sale is often called an IPO.

What Anthropic said

Anthropic said it wants to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT.

Class A common stock means ordinary shares that trade on a public market. Nasdaq Global Select is one of Nasdaq's main boards for large firms.

Anthropic said it has not yet set how many shares it will sell or at what price range.

Who will handle the sale

The banks Goldman Sachs and Morgan Stanley will prepare the prospectus. A prospectus is the long document that explains the offer to buyers.

What is confirmed and what is not

The S-1 has been filed with the U.S. Securities and Exchange Commission, or SEC. The SEC is the U.S. agency that watches public stock sales.

Anthropic said the registration is not yet effective. That means the shares cannot be sold yet, and no one can accept offers to buy them until the filing becomes effective.

Anthropic also said today's note is not an offer to sell the shares.
