Anthropic filed a Form S-1 registration statement with the US Securities and Exchange Commission on October 26, 2026. It says the company intends to list on the Nasdaq Global Select Market under the symbol ANT. The S-1 is the registration document for the proposed sale. It establishes a formal step toward a listing, with pricing and timing still to be clarified.
What valuation are investors discussing?
According to The Wall Street Journal, three large prospective investors said the expected $1.5 trillion valuation might have to come down. One suggested a figure closer to $1 trillion. The paper reported that a listing before Thanksgiving had been discussed and that market conditions could lead to a delay. Those are reported expectations and investor views.
Why are valuation and proceeds separate?
Valuation is the implied value of the whole company at the offering price. Proceeds are the money paid for the shares actually sold in the offering. The paper’s reported fundraising target of up to $100 billion, and the possibility of a smaller offering, refer to the second figure. When existing holders sell shares, the money for those shares goes to the sellers.
What to look for in the next filing
I’d start with the price range, the number of shares offered and the split between shares sold by Anthropic and by existing holders. Those details show how much the company could receive and what assumptions underlie the valuation. For timing, an updated statement from the company gives you a firmer date than investors’ expectations.
