Antropic is in talks to use Microsoft's own AI chip after a $5 billion investment deal. Here's what we know

CNBC has confirmed that Microsoft is actively in talks to supply Anthropic with its own Maia AI chip. No deal has been reached, according to a person familiar with the matter who requested anonymity to discuss internal negotiations. The discussions were first reported on Thursday by The Information.

What is the Microsoft Maia 200 chip and why does it matter?

Microsoft unveiled its second-generation Maia AI processor in January, positioning it as a competitive alternative to the proprietary silicon offered by cloud rivals Amazon and Google.

The chip has not yet been made available to Azure customers in a commercial capacity, although Microsoft CEO Satya Nadella confirmed in April that it is already operational in the company’s Arizona and Iowa data centers.

On the company’s April earnings call, Nadella said the Maia 200 “offers more than 30% better tokens per dollar compared to the latest silicon in our fleet.” Microsoft also confirmed that the processor will be used to run the OpenAI GPT-5.2 model.

A deal with Anthropic would represent a major commercial milestone for the chip, giving Microsoft a high-profile client and validating the Maia platform at scale.

Why Anthropic needs more computing power

Anthropic’s interest in additional chip shipments reflects a broader and increasingly pressing challenge facing the company. Dario Amodei, Anthropic’s co-founder and CEO, admitted at an industry event earlier this month that the company has “calculation difficulties.”

The tension was building. Anthropic’s Claude AI assistant and its Claude Code AI-assisted programming tool have grown in popularity significantly this year, placing greater demands on the company’s existing computing infrastructure. This growth has made ensuring sufficient capacity an urgent operational priority.

The scale of that need was underscored Wednesday, when SpaceX disclosed in a filing that Anthropic will pay $1.25 billion a month for computing power through May 2029.

The expanding cloud and chip network from Antropic

Anthropic has historically relied on graphics processing units from Nvidia to train and run its generative AI models, but the company continues to expand its hardware partnerships.

In April, Anthropic announced it would acquire its own Trainium chips from Amazon Web Services in a 10-year deal worth more than $100 billion. The company also announced plans to use Google’s Tensor Processing Unit chips in October. In addition to these agreements, Anthropic continues to use cloud services from both Amazon and Google.

A potential Microsoft deal would add a fourth major chip relationship to that portfolio, underscoring how aggressively the company is trying to strengthen its computing foundation.

Microsoft’s $5 billion investment and Azure’s $30 billion commitment

The negotiations for access to the Maia chip are part of an already significant financial relationship. In November, Microsoft announced that it would invest $5 billion in Anthropic. As part of the arrangement, Anthropic committed to spending $30 billion on Azure cloud services over the life of the agreement.

The chip supply deal would therefore build on an existing partnership rather than establish an entirely new partnership, giving Microsoft a deeper operational role in powering Anthropic’s AI systems than simply hosting it on its cloud infrastructure.

Microsoft is playing catch-up in Silicon’s own AI

In Microsoft’s case, the deal’s stake goes beyond just the revenue it would generate. The company currently lags behind both Amazon and Google in the market for its own AI silicon supplied to enterprise clients. A major deal with one of the most closely watched AI companies would help address this gap and signal broader commercial confidence in the Maia platform.

Microsoft shares were little changed on the news. Anthropic declined to comment. Microsoft did not immediately respond to a request for comment.
