Anthropic IPO Could Send Ripples Through Amazon's Bottom Line

Anthropic, an AI lab backed by Amazon and valued at $965 billion, is reportedly eyeing an IPO on par with SpaceX's. The company has already raised around $133 billion, with recent quarterly revenue surpassing $11.5 billion and an annualized run rate approaching $65 billion.

Amazon investors have a vested interest in Anthropic's public debut, given the tech giant's significant investment of $13 billion in the AI lab. The partnership between Amazon and Anthropic goes beyond equity ownership, with Anthropic utilizing Amazon's custom silicon for training and inference. This includes a massive deployment under Project Rainier that utilizes over 1 million Amazon Trainium chips.

Anthropic's S-1 will provide more precise disclosure around Amazon's ownership, allowing investors to better model the position's value. With accurate knowledge of Amazon's stake, investors can improve forecasts of AWS' revenue acceleration and operating margin expansion driven by Anthropic's compute demands.
