AI Frenzy Adds $200 Billion to Chip Stocks – Nvidia, AMD Soar on Record Rally
After a brief lull in sentiment, enthusiasm about artificial intelligence came roaring back in early October 2025 – sparking a record-setting rally in semiconductor stocks. Globally, chipmakers added over $200 billion in combined market value within days as investors piled into the sector on fresh AI optimismelectronicsforyou.biz. NVIDIA looked set to power higher, and fellow AI-exposed names like Advanced Micro Devices and Broadcom were also climbing amid renewed spending excitement driven by OpenAIitiger.com. This marked one of the biggest tech stock booms since the initial ChatGPT craze, reaffirming that AI remains the key narrative propelling markets.
