The AI boom could be heading to millions of 401(k)s as Anthropic files for IPO

Anthropic, maker of the chatbot Claude, said Monday that it had filed confidential paperwork with federal regulators in preparation for selling its stock to the public. The company is expected to be one of three trillion-dollar debuts on the stock market this year, along with Elon Musk’s rocket and AI venture SpaceX and OpenAI, maker of ChatGPT. SpaceX filed to go public in April and OpenAI is expected to do so soon. (The Washington Post has a content partnership with OpenAI.)Subscribe to The Po
