- NVIDIA shares closed 1.29% lower on Monday after Microsoft unveiled its Azure Maia 300 AI chip
- AMD shares fell 2.28% while Microsoft gained 1.14% on the news
- Microsoft’s new chip delivers 40% more tokens per megawatt for greater AI efficiency
- The move signals Microsoft’s push to reduce reliance on Nvidia and AMD
Nvidia (NVDA) stock price has taken a hit, closing 1.29% (2.96 points) lower on Monday, October 12, 2026. The latest dip comes after Microsoft (MSFT) revealed its Azure Maia 300 AI chip, aiming to reduce reliance on Nvidia and Advanced Micro Devices (AMD).
Consequently, AMD shares closed 2.28% lower on Monday, with an additional 1.46% drop in after-market hours. Microsoft, by contrast, gained 1.14% on Monday and rose 0.18% after market close.
The price movements are most likely due to Microsoft’s latest AI chip revelation, as the company previously depended on Nvidia and AMD processors. With Azure Maia 300, Microsoft could become self-reliant, potentially dealing a significant blow to both chipmakers.
Meanwhile, Microsoft stated that Maia 300 delivers 40% more tokens per megawatt than other GPU-based systems, enabling more efficient AI racks. The Maia 200 chip currently powers Microsoft production workloads, including Microsoft 365 Copilot, OpenAI models, MAI models, and several open-source models.
This growing model list could threaten Nvidia’s dominance, and other firms may follow Microsoft’s path toward self-reliance. Nonetheless, Nvidia and AMD remain major players in data center and AI chips, with Wall Street bullish on both companies’ revenue and earnings expectations.
