Advanced Micro Devices Inc. reached a $1 trillion market capitalization for the first time on Monday, September 21, 2026, as its stock surged 9% to an intraday high of $613.92. The milestone reflects sustained investor confidence in chipmakers powering artificial intelligence infrastructure, with AMD riding a five-day rally that has added approximately 24% to its share price since mid-September. The stock is up more than 180% for the year.

AMD's growth is anchored in its data center business, which reported Q2 sales of $6.7 billion, representing a 107% year-over-year increase. The company's overall Q2 revenue reached $11.54 billion, up 50% from $7.69 billion in the same period last year, driven primarily by demand for AI-capable processors. CEO Lisa Su indicated on the company's recent earnings call that AMD expects to double data center sales in 2027, signaling confidence in sustained demand from the AI buildout.

Despite its historic achievement, AMD remains significantly smaller than market leader Nvidia, which commands a market capitalization of approximately $5.4 trillion. Industry observers note that the AI infrastructure expansion shows few signs of slowing, despite public concerns about data center power consumption and the safety of large language models. Nvidia CEO Jensen Huang has similarly signaled strong demand ahead, stating his company expects to double chip shipments in 2027.
