Anthropic’s IPO filing shows explosive growth, risks and staggering costs
The filing sets up the company for a Wall Street debut next month, potentially eclipsing SpaceX's IPO.

Artificial intelligence giant Anthropic has filed papers for what could be the biggest ever initial public offering (IPO) of stock, even as its top executive warns that advanced AI could pose an existential threat to humanity.
The filing on Monday sets up the San Francisco company for a Wall Street debut next month, potentially eclipsing the SpaceX initial public offering in June that raised a record $86bn.
The filing comes weeks after chief executive and cofounder Dario Amodei argued in an essay for slowing the development of the most advanced AI models. An IPO could provide Anthropic with enormous resources to accelerate its expansion. The amount the company ultimately raises remains uncertain, as does its final valuation and offering price. But even at lower estimates, it would turn the five-year-old startup into one of the world’s most valuable companies and potentially boost the wealth of Amodei and his sister and cofounder, Daniela, by billions of dollars.
“Anthropic’s IPO will establish a benchmark for valuing leading AI labs, influencing both upcoming listings and confidence in the companies funding the AI infrastructure build-out,” IPOX research associate Lukas Muehlbauer said.
