Microsoft Challenges Nvidia with Maia 200 AI Chip Launch

Microsoft has unveiled its second-generation AI chip, the Maia 200, marking a strategic MOVE to reduce reliance on Nvidia's dominant position in the AI hardware market. Built on TSMC's advanced 3nm process, the chip is optimized for AI inference workloads in Azure data centers, delivering over 10 petaFLOPS in 4-bit precision with 216GB of HBM3e memory. It will power OpenAI's GPT-5.2 models, signaling Microsoft's commitment to in-house AI infrastructure.

Nvidia's stock showed minimal volatility post-announcement, dipping just 0.64%, as investors weigh long-term implications. The Maia 200 is already operational in Microsoft's Iowa datacenter, with broader rollout planned for later this year. This development mirrors similar initiatives by Google and Amazon, as Big Tech seeks cost efficiency and supply chain resilience through custom silicon solutions.

While not a direct replacement for Nvidia's offerings, the Maia 200 provides Microsoft with greater control over AI workload optimization and operational expenses. The chip's specialized inference capabilities highlight the growing segmentation in AI hardware markets, where different components of the AI pipeline—training versus inference—are increasingly served by tailored solutions.
