New York: Artificial intelligence giant Anthropic is looking for an approximately USD 1.3 trillion valuation in an initial public offering despite new questions about the massive amounts of money flowing into the sector. The company behind the Claude chatbot said in a regulatory filing on Tuesday that it will sell 825 million shares priced between USD 70 and USD 78 a share. That would give Anthropic the ability to raise more than USD 61 billion, if the IPO is priced at the midpoint. The San Francisco company is anticipated to make its Wall Street debut this month. Anthropic could wind up being the biggest initial public offering of stock ever, possibly eclipsing the record USD 86 billion raised by SpaceX in its IPO in June. An Anthropic IPO would also put the company ahead of OpenAI in going public, setting the stage for a pair of blockbuster stock debuts by rival AI developers.
