Investors discuss cutting Anthropic's IPO valuation to $1.5 trillion on slowing revenue growth

Prepared by Sintelligent with the help of SI. Published in SI: . Updated: .

Investors' expectations for Anthropic are falling along with its slowing revenue growth, but the final valuation has not yet been announced.

According to Reuters (paywalled; details are from AI Weekly's and 3DNews' retelling), participants in Anthropic's investor day in San Francisco discussed a valuation of about $1.5 trillion at the November IPO instead of about $2 trillion. The reason is a slowdown: third-quarter revenue grew 45% to $16.8 billion, while in the second quarter it nearly doubled to $11.6 billion. Operating losses over the year exceeded $8 billion; the company has committed to spend more than $518 billion on cloud infrastructure and compute over ten years. The final valuation has not been announced.
