Microsoft in major deal with Anthropic to bring Claude to Azure
Microsoft and Anthropic have entered into a major partnership bringing the Claude AI models to Microsoft Foundry on Azure. The agreement also includes $30 billion in computing capacity.
What happened?
Microsoft has entered into a strategic partnership with AI company Anthropic to make their Claude models available via Microsoft Foundry on Azure. The agreement involves Anthropic committing to purchase $30 billion in Azure computing capacity, as well as signing deals for additional capacity of up to one gigawatt. At the same time, it is clarified that Amazon remains Anthropic’s primary cloud provider and training partner.
Key facts
| Köp av beräkningskapacitet | 30 miljarder USD |
|---|---|
| Ytterligare elkraftskapacitet | Upp till 1 gigawatt |
| Tillgängliga modeller | Claude Sonnet 4.5, Opus 4.1, Haiku 4.5 |
| Primär molnpartner | Amazon (kvarstår) |
Why it matters
Through this agreement, Microsoft Azure customers gain access to advanced frontier models such as Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5 directly within the platform. For Anthropic, the deal secures massive computing resources for future AI development and expands their reach into Microsoft's extensive enterprise customer base.
Who is affected?
The initiative primarily concerns developers, data scientists, and enterprise companies building AI applications on Microsoft Azure. They now have the option to select Anthropic’s models directly within the Microsoft ecosystem. Nvidia is also involved in a parallel collaboration to optimise Claude models on its future hardware architecture.
Impact on the EU
The services are being made available globally via Microsoft Azure, meaning developers and companies within the EU will also gain access to the Claude models through Azure Foundry, provided that applicable data protection regulations and the EU AI Act are complied with.
What else you should know
The collaboration is notable as Microsoft is already the primary investor in OpenAI, the Anthropic competitor behind ChatGPT. Offering Claude on Azure highlights a growing trend where cloud giants provide broad model catalogues to prevent enterprise customers from switching cloud platforms.
