AMD Surpasses $1 Trillion Market Cap Amidst AI Chip Boom and Record Rally
On September 21, 2026, Advanced Micro Devices (AMD) achieved a historic milestone. The company’s stock surged by 9.95%, closing at $615.52 on the Nasdaq. This significant increase pushed AMD’s market capitalization above $1 trillion for the first time in its history. The intraday high of $616.69 set a new 52-week record, with trading volume reaching over 43 million shares – a notable 31% above the average session.
This rally concluded a remarkable five-day surge of approximately 25%. Consequently, AMD’s year-to-date gain is now close to 190%, significantly outperforming the broader Nasdaq index. A key catalyst for this surge was the growing investor enthusiasm surrounding Meta’s new AI Agent product, Muse. This product ignited expectations for a sharp increase in server CPU demand for AI inference workloads. Additionally, AMD’s second-quarter revenue of $11.54 billion — a 50% year-over-year increase — further impressed Wall Street.
AMD’s growth story now extends beyond challenging Nvidia in the GPU market. The company is making strides in server CPUs, AI accelerators, and complete AI systems. Positive bilateral U.S.-China trade talks, easing oil prices, and falling Treasury yields provided additional tailwinds for the semiconductor sector. AMD’s milestone underscores the significant impact of the global AI infrastructure buildout on the competitive landscape among chipmakers.
