Anthropic IPO 825 million shares offered… existing shareholders to sell 23,648,646 shares

Anthropic filed an amended S-1 with the SEC for a Nasdaq IPO under the ticker ANT, offering 825 million Class A shares at an expected price range of $70–78, with 801.35 million new shares issued by the company and 23.65 million sold by existing shareholders, whose proceeds will not go to the company. Yahoo Finance reported a target valuation of $1.3–1.4 trillion, which would rank among the largest listings on record and marks a major test of public-market appetite for frontier AI developers. The split between primary and secondary shares matters because only the new-share portion raises fresh capital for Anthropic, while the secondary sale gives early backers liquidity.
