Microsoft, NVIDIA Commit Up to $15 B to Back Anthropic in New AI Partnership

Microsoft and NVIDIA have announced a joint investment of up to $15 billion to support Anthropic, the maker of Claude AI models. Microsoft will invest up to $10 billion while NVIDIA contributes up to $5 billion. In return, Anthropic will purchase $30 billion in Azure cloud capacity and may add up to one gigawatt of additional compute. The partnership also includes integration of Claude models into Microsoft Foundry, and collaboration with NVIDIA to optimize Anthropic’s models for NVIDIA hardware and future architectures. The deal arrives as Microsoft loosens its exclusivity with OpenAI and follows recent large cloud contracts with Amazon.

Investment Overview

Microsoft and NVIDIA have each pledged substantial capital to bolster Anthropic, the creator of the Claude series of AI models. Microsoft’s commitment tops out at $10 billion, while NVIDIA is prepared to provide up to $5 billion, bringing the combined investment to a maximum of $15 billion.

Azure Cloud Commitment

As part of the agreement, Anthropic will purchase $30 billion worth of Azure cloud computing capacity from Microsoft. The firm also indicated it could contract additional capacity that would total up to one gigawatt, underscoring the scale of compute resources that will be dedicated to training and running its AI models.

Model Access and Integration

Microsoft Foundry customers will gain direct access to a suite of Claude models, including Sonnet 4.5, Opus 4.1 and Haiku 4.5. This integration expands the toolbox available to enterprises building on Microsoft’s AI platform and positions Claude alongside other leading large‑language models.

Collaboration with NVIDIA

NVIDIA and Anthropic will work together to improve the performance of Claude models on NVIDIA hardware. The partnership also aims to optimize future NVIDIA architectures specifically for Anthropic’s needs, ensuring the models can exploit the latest GPU advances.

Broader Industry Context

The deal arrives as Microsoft revises its partnership with OpenAI, loosening exclusivity that previously limited the company’s AI collaborations. In parallel, OpenAI recently signed a $38 billion cloud contract with Amazon, and Anthropic announced it will use AWS AI chips after Amazon invested an additional $4 billion in the Claude maker.

Strategic Implications

By spreading its AI investments across multiple partners, Microsoft signals a diversification strategy that mitigates reliance on a single provider. NVIDIA’s involvement reinforces its role as a key hardware supplier for advanced AI workloads, while Anthropic secures both cloud capacity and hardware optimization to accelerate its model development.
