Amazon's AI bet on Anthropic soars to $61 billion valuation

February 6, 2026 - 20:33

The valuation of artificial intelligence startup Anthropic has skyrocketed to an estimated $61 billion, marking a dramatic increase and highlighting the immense financial stakes in the AI sector. This surge follows a series of successful funding rounds, with Amazon emerging as a pivotal financial backer through a sophisticated investment structure.

Rather than a direct equity purchase, Amazon's cloud division initially secured its position by holding convertible notes in Anthropic. This financial instrument acted as a form of debt that has now converted into a significant equity stake as the AI company achieved new funding milestones. The arrangement provided Amazon with a strategic pathway to a major share in one of OpenAI's primary competitors.

The soaring valuation underscores the frenzied investor confidence surrounding foundational AI models and their potential to reshape the technology landscape. Anthropic, known for its Claude AI assistant and a strong focus on AI safety, has become a central player in the industry's rapid expansion. This substantial increase in worth reflects both the startup's technological promise and the strategic importance major tech corporations like Amazon place on securing influence within the AI ecosystem. The deal also deepens the existing partnership between the two firms, with Anthropic utilizing Amazon Web Services as its primary cloud provider.
