Microsoft Talks Maia 200 Chip Supply to Anthropic via Azure

Microsoft is in talks to supply Anthropic, the San Francisco AI firm behind Claude, with its Maia 200 AI chips through Azure. The deal has not been finalized, but it could help Microsoft narrow the gap with Amazon and Google in offering custom AI chips to cloud customers. In November, Microsoft invested US$5 billion in Anthropic. Anthropic committed to spend US$30 billion on Azure, while the startup also uses Nvidia GPUs plus custom chips from Amazon and Google.

Maia 200 Targets AI Inference Efficiency

Microsoft's Maia 200 is built for AI inference—the work of running a trained model to generate responses—rather than as a general-purpose chip. Running large AI services over time can cost more than training the model in the first place. Microsoft says Maia 200 offers 30% better performance per dollar, which could cut daily costs for a high-volume customer or enable features such as longer context windows without raising budget. The chip also aims to keep response times steadier during traffic spikes, which matters for companies building products on Anthropic's models.

Custom Chips Reshape AI Competition

The talks suggest the race is moving beyond buying more Nvidia graphics processing units (GPUs). Companies are pairing model makers with custom chip platforms and the cloud systems that run them. Anthropic is already taking that approach with Google and Broadcom, a chip designer and infrastructure company. It is tuning its Claude models to work more closely with Google's Tensor Processing Unit (TPU) hardware and software stack. A similar arrangement with Microsoft for Maia 200 could back a multicloud plan with more than one chip supplier, widening Anthropic's access to custom silicon through Azure. Shipments of custom chips from cloud providers are projected to rise 44.6% in 2026, versus 16.1% growth for GPUs.
