Anthropic IPO Could Make Amazon Investors Very Rich

Amazon's $200 billion+ stake in AI startup Anthropic could be worth more than its current market value if the company successfully goes public this October. The startup, which is one of the world's fastest-growing AI companies, was valued at $965 billion after its latest funding round in May and is targeting an IPO valuation of at least $1 trillion.

This means Amazon's 21% stake, built up with a total investment of $13 billion ($8 billion in 2024 and $5 billion earlier this year), could be worth over $210 billion when Anthropic goes public. The successful IPO would not only boost Anthropic's revenue but also directly support AWS' growth, as the startup is required to use Amazon Web Services as its primary cloud infrastructure provider.

Amazon has already recorded massive unrealized gains from its investment in Anthropic, with a $53.4 billion net income boost in the second quarter of 2026. However, these gains have already been priced into Amazon's stock, and a market debut at $1 trillion wouldn't instantly boost its net income.
