Amazon.com IncAmazon's 15%-20% Anthropic stake could be worth $300B+ at IPO, plus Anthropic's commitment to spend tens of billions on AWS.
Anthropic is preparing to file an S-1 prospectus in early October ahead of an initial public offering expected in October or early November at an estimated $2 trillion valuation. Individual investors cannot buy Anthropic shares before the IPO, but they may already hold indirect exposure through Alphabet and Amazon, which have funded the AI company in exchange for commitments to spend tens of billions on Google Cloud and Amazon Web Services. Analysts estimate Amazon's stake at 15%-20% and Alphabet's at 10%-15%, though exact figures will not be known until the S-1 is filed; at the low end of those ranges, Amazon's 15% stake would be worth $300 billion and Alphabet's 10% stake $200 billion. Anthropic reports annualized revenue of $65 billion, up from $9 billion at the end of 2025, and that figure could reach $100 billion by October, though heavy upfront spending on cutting-edge AI models likely means large cash burn. The company is expected to raise an estimated $100 billion in the IPO, and last quarter AWS revenue rose 37% year-over-year to $42.2 billion at a 39% profit margin, while Google Cloud revenue increased 82% to $24.8 billion at a 35% profit margin.
