Anthropic has secured commitments of up to US$15 billion from Microsoft and NVIDIA as part of a sweeping strategic partnership that will see the Claude maker spend $30 billion on Azure compute capacity and adopt NVIDIA's next-generation chip architecture.
The deal sees Microsoft invest up to $10 billion and NVIDIA up to $5 billion in Anthropic, marking NVIDIA's first deep technology partnership with the AI safety-focused company.
Also part of the agreement, Anthropic has committed to purchase $30 billion of Azure compute capacity and contract additional capacity up to one gigawatt.
The company's compute commitment will initially run on NVIDIA Grace Blackwell and Vera Rubin systems, with both firms collaborating on design and engineering to optimise performance.
"Anthropic is scaling its rapidly-growing Claude AI model on Microsoft Azure, powered by NVIDIA, which will broaden access to Claude and provide Azure enterprise customers with expanded model choice and new capabilities," Microsoft said in a blog post.
The partnership makes Claude the only frontier AI model available across all three major cloud platforms - Microsoft Azure, Amazon Web Services, and Google Cloud.
Microsoft has also committed to continuing Claude access across its Copilot family, including GitHub Copilot, Microsoft 365 Copilot, and Copilot Studio, while customers of Microsoft Foundry will gain access to Anthropic's frontier models, including Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5.
Stacking capital
The investment follows Anthropic's monster $13 billion Series F raise in September, which valued the company at $183 billion and was led by Iconiq Capital alongside Fidelity and Lightspeed Venture Partners.
BlackRock, Goldman Sachs Alternatives, GIC, and Qatar Investment Authority were among participants in that round.
Combined with the fresh Microsoft-NVIDIA capital, Anthropic has now secured approximately $27 billion in funding since its January 2021 inception - a figure that balloons significantly with the new compute commitments factored in.
The company's revenue trajectory supports the premium valuation, with run-rate revenue surging from $1 billion at the start of 2025 to more than $5 billion by August - a fivefold jump in eight months.
Anthropic now serves over 300,000 business customers, with large accounts growing nearly sevenfold year-on-year.
Claude Code has been a standout performer since its May 2025 launch, generating over $500 million in run-rate revenue with usage up more than 10x in three months.
The compute arms race
The scale of Anthropic's Azure commitment - $30 billion with up to one gigawatt of capacity - underscores just how capital-intensive frontier AI development has become.
Training and running large language models requires vast compute resources, and securing that infrastructure now appears as critical as the model development itself.
For Microsoft, the deal diversifies its AI portfolio beyond OpenAI, while for NVIDIA, it locks in another major customer for its latest silicon hardware.
For Anthropic - it's the compute firepower needed to compete at the frontier of artificial intelligence.
