AMD's market capitalization surpasses $1 trillion, as AI agents reignite market attention on demand for CPU computing power.

Beating AI Express (from Dongcha) – AMD’s stock closed up nearly 10% on September 21 to $615.52, hitting an all-time high. The chipmaker’s market capitalization crossed $1 trillion for the first time, making it the fourth U.S. semiconductor firm to reach this valuation, following NVIDIA, Broadcom, and Micron. AMD has rallied roughly 24% over the past five trading days, with its year-to-date gain exceeding 180%. One direct catalyst for the recent surge is the market’s re-evaluation of AI agents’ demand for CPU computing power. Meta’s newly launched personal AI agent Muse quickly gained traction: it amassed 730,000 downloads in just five days and topped the U.S. Apple App Store’s free app chart on September 18. Market participants note that as AI agents become more widespread, server CPUs will see increased workloads in inference, task orchestration, and infrastructure operations. AMD’s second-quarter revenue rose 50% year-over-year to $11.54 billion, with its data center business generating $6.7 billion in revenue, up 107% YoY. Meta currently accounts for around 5.5% of AMD’s total revenue, ranking as the chipmaker’s second-largest customer. As AI applications expand beyond model training to agent deployment, market focus on AI infrastructure is shifting from GPUs to CPUs and other general computing resources.
