Anthropic to Raise $15 billion from Microsoft and Nvidia, Sets $30B Azure Cloud Deal

Microsoft and Nvidia are making a major play in the AI space with a joint investment of up to $15 billion in Anthropic, the company behind the Claude AI models. Nvidia is committing as much as $10 billion, while Microsoft is investing up to $5 billion, according to company statements.

As part of the deal, Anthropic has pledged to spend $30 billion on cloud compute services via Microsoft’s Azure, marking one of the largest long-term commitments to cloud infrastructure by an AI company to date.

Strategic Shift in the AI Race

The partnership signals a broader strategic recalibration in the rapidly evolving AI landscape. Microsoft is diversifying its AI alliances and reducing its reliance on OpenAI by strengthening ties with Anthropic. Meanwhile, Anthropic gains long-term access to the extensive compute resources required to scale its frontier models and meet rising enterprise demand.

Anthropic will also tap into Nvidia’s advanced hardware, with plans to use up to 1 gigawatt of compute capacity powered by Nvidia’s Grace Blackwell and Vera Rubin architectures. This collaboration sets the stage for joint chip-model optimizations aimed at improving performance and efficiency.

Claude Models Enter Microsoft’s AI Ecosystem

As part of the agreement, Microsoft will integrate Anthropic’s Claude models – including Claude Sonnet 4.5, Opus 4.1, and Haiku 4.5 – into its Azure AI Foundry platform. The move positions Claude as the only frontier AI model available across all major cloud providers.

Despite Anthropic’s expanded partnership with Microsoft, Amazon remains its primary cloud provider and training partner.

Market Implications

For Microsoft, the investment strengthens its competitive edge in cloud and AI, while providing more flexibility beyond its collaboration with OpenAI. Nvidia, on the other hand, deepens its role as the foundational hardware layer powering next-generation AI workloads.

For Anthropic, the commitments highlight confidence in the continued growth of enterprise AI adoption. The company is projected to reach an annualized revenue run rate of $26 billion next year and now sits at a valuation of around $183 billion.

However, analysts have raised concerns about the circular nature of such deals, where cloud providers invest in AI companies that in turn commit large sums back into their infrastructure.

The strategic triad between Microsoft, Nvidia, and Anthropic marks a significant milestone in the AI infrastructure race. With massive investments, long-term compute commitments, and expanded model availability, the partnership is poised to reshape competition across the global AI ecosystem.
