Anthropic is preparing to go public on Nasdaq under ticker ANT, with CEO Dario Amodei presenting the offering as a way to fund computing capacity and manage uncertain demand. During a Friday livestreamed fireside chat at JPMorgan Chase’s Manhattan headquarters, hosted by Chief Executive Jamie Dimon, Amodei said he hoped the company would underpromise and overdeliver on the IPO. Anthropic expects to price shares Wednesday and begin trading Thursday, November 19, seeking as much as $90.4 billion through the IPO and a concurrent private share sale at an approximately $1.4 trillion valuation, according to its IPO website. Fubon Life, a subsidiary of Fubon Financial Holding (2881.TW), separately said its board approved participation in the U.S. offering, capped at $700 million. Pershing Square Capital CEO Bill Ackman plans to avoid the offering despite praising Anthropic, citing valuation uncertainty and substantial capital needs. Anthropic’s amended S-1 reported third-quarter revenue of $17 billion, up 1,127%, alongside a $23.29 billion loss, while sequential growth slowed to 47%.
