Anthropic confidentially filed its draft S-1 with the SEC on June 1, 2026, but as of mid-October the public version still hasn’t appeared on EDGAR. Until it does, there is no official price range, ticker or listing date. Reports point to Nasdaq and a listing after the November midterms, but the company hasn’t confirmed either.
The public S-1 is the document to watch. It will show the ticker, the exchange and the price range, and trading usually starts two to three weeks after it is posted.
