Factbox-Amazon, Google set for big windfall from Anthropic IPO

Nov 10 (Reuters) – Amazon and Google’s stakes in Anthropic could be worth a combined $411 billion if the AI company prices its initial public offering at the top of its proposed range, according to Reuters calculations based on a filing.

The figures show how much early bets by the two cloud giants have grown. They have put money into Anthropic while also selling it the computing power it needs to build its AI models.
