What did Anthropic announce?
On 26 October 2026, Anthropic, PBC filed a registration statement on Form S-1 with the US Securities and Exchange Commission (SEC). It relates to the proposed initial public offering, or IPO, of its Class A common stock.
An IPO is when a private company sells its shares to the public for the first time.
Where will Anthropic shares trade?
Anthropic says it intends to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT".
How many shares and at what price?
That has not been decided. Anthropic says the number of shares to be offered and the price range have not yet been determined.
Can I buy Anthropic shares now?
No. Anthropic says the registration statement has been filed with the SEC but has not yet become effective, and that the securities may not be sold, nor offers to buy accepted, before it does. The offering will be made only by means of a prospectus. Anthropic names Goldman Sachs and Morgan Stanley as the places to request copies of the preliminary prospectus.
Is this the first filing?
No. On 1 June 2026, Anthropic said it had confidentially submitted a draft S-1 to the SEC, NPR reported. Today's announcement is of the registration statement itself. Anthropic's page does not give a date for the listing.
Why does it matter?
Anthropic makes Claude, one of the best known AI assistants. A public listing would let ordinary investors own a piece of one of the leading AI labs, and would require it to publish regular financial reports.
What's next?
Anthropic still has to set the number of shares and the price range, and the SEC registration has to become effective before any shares can be sold. Anthropic has not announced a listing date.
