Anthropic is reportedly in talks with Microsoft (MSFT) to rent the company’s custom AI server chips as it looks to expand its computing capacity to keep up with rising demand for AI services, according to a report by The Information.
Microsoft, along with Alphabet’s (GOOG, GOOGL) Google and Amazon.com Inc. (AMZN), has been developing its own custom chips to reduce dependence on Nvidia’s (NVDA) semiconductors. Microsoft’s Maia chips could offer Anthropic an alternative way to run its Claude models more efficiently.
The discussions between Microsoft and Anthropic are still in their early stages and may not lead to a final agreement, according to the report.
Maia chips are reportedly designed to run existing AI models faster than Nvidia’s hardware, but they are not intended for training or building new models.
Microsoft introduced the Maia 200 processor in January 2026. The chip is built using Taiwan Semiconductor Manufacturing Co.’s (TSMC) 3-nanometer process technology.
Each tray connects four Maia accelerators with direct, non-switched links, keeping high-bandwidth communication within the system to improve inference efficiency. The chips rely on Ethernet connections, a different networking approach from Nvidia’s InfiniBand-based systems.
In its launch note, Microsoft said the Maia 200 includes more high-bandwidth memory than Amazon Web Services’ third-generation Trainium chip and Google’s seventh-generation Tensor Processing Unit. Microsoft CEO Satya Nadella said on X that it delivers “30% better performance per dollar” compared with current systems.
Stocktwits retail sentiment for Microsoft is ‘bullish’ with message volume being ‘high.’ In the past 24 hours, retail sentiment has shifted from ‘neutral’ to ‘bullish,’ while message volume has remained unchanged.
One bullish user on Stocktwits said, “Microsoft is short on Nvidia GPUs, not on its own Maia chips,” while the real constraint is “power availability.”
At the time of writing, MSFT shares were trading 0.9% down at $417 apiece.
MSFT stock has fallen about 14% year-to-date.
