Amazon's $200 Billion Stake in Anthropic to Be Put to Test

Amazon's significant stake in Anthropic, an AI startup valued at over $1 trillion, could be worth more than $210 billion to Amazon investors. The company owns a 21% stake in Anthropic, which was built up with investments totaling $13 billion in 2024 and earlier this year. If Anthropic meets its reported IPO valuation target of $1 trillion, Amazon's gains from the investment would be substantial.

Anthropic has been rapidly growing, with annualized revenue reaching $9 billion at the end of 2025 and soaring to $47 billion in mid-May. The company claims its operating profit will turn positive for the first time in the second quarter of 2026, driven by robust enterprise demand for its Claude AI models.

Amazon's investors should take note of Anthropic's IPO, as it could be a major catalyst for Amazon's stock. A successful market debut would directly boost Amazon's net income and support the growth of Amazon Web Services (AWS), which generates most of the company's operating profits.
