Anthropic and Microsoft in Talks Over Maia AI Chip Deal

CNBC reported Thursday that Anthropic and Microsoft are in active negotiations over the use of Microsoft’s custom Maia AI chip, though no agreement has been finalized. A person familiar with the discussions confirmed the talks to CNBC on condition of anonymity.

Microsoft Seeks Ground in Custom Silicon Race

Microsoft unveiled its second-generation Maia 200 processor in January but has not yet made it commercially available to Azure customers. The chip currently operates exclusively inside Microsoft’s own data centers. CEO Satya Nadella said on the company’s April earnings call that the Maia 200 delivers more than 30% better token efficiency per dollar compared to other processors in its fleet. Active deployments are running at Microsoft facilities in Arizona and Iowa. A deal with Anthropic would mark a meaningful commercial breakthrough for the chip and close some of the gap between Microsoft and cloud rivals Amazon and Google, both of which already supply Anthropic with custom silicon.

Anthropic’s Compute Crunch Drives Search for New Silicon

Anthropic CEO Dario Amodei publicly acknowledged at an industry event earlier this month that the company has experienced significant difficulties securing enough computing capacity. Demand for its Claude assistant and Claude Code programming tool has accelerated sharply this year, straining infrastructure. SpaceX disclosed Wednesday that Anthropic will pay $1.25 billion per month through May 2029 for compute resources, underscoring the scale of the company’s hardware needs.

A Growing Web of Chip Partnerships

Anthropic has moved aggressively to diversify its compute supply chain beyond Nvidia graphics processing units. In April, the company announced a 10-year arrangement with Amazon Web Services worth over $100 billion, incorporating AWS’s custom Trainium processors. Separately, Anthropic committed to using Google’s tensor processing unit chips in a deal announced last October. The Microsoft talks add yet another layer to what is becoming an unusually broad hardware portfolio for a single AI lab.

Investment Ties Deepen the Stakes

Microsoft pledged $5 billion in Anthropic in November, with Anthropic simultaneously committing to spend $30 billion on Azure services over time. That financial relationship gives both companies strong incentive to deepen technical cooperation. Microsoft shares were little changed following the reports of the chip discussions. Neither company had commented publicly by the time CNBC published its report.
