Advanced Micro Devices briefly surpasses $1 trillion market valuation amid surging artificial intelligence demand

The rally was partly fueled by Meta’s Muse AI Agent reaching the top spot among free apps on Apple’s App Store, renewing investor interest in CPUs needed for consumer-facing “agentic AI.”
Jefferies analyst Jacky He said broader adoption of AI agents could increase demand for server CPUs because of higher inference, orchestration and infrastructure workloads.
Meta is AMD’s second-largest customer and accounted for about 5.5% of the company’s revenue, underscoring the importance of major cloud and technology customers to AMD’s AI growth story.
AMD CEO Lisa Su said the company expects to double data-center sales by 2027, while the stock had risen more than 180% during the year by the time it crossed the valuation milestone.
Despite AMD’s gains, Nvidia remained far ahead in valuation, with a market capitalization of about $5.4 trillion, highlighting the scale of the gap between AMD and the AI-chip market leader.
Advanced Micro Devices briefly surpassed $1 trillion in market value on September 21, becoming the fourth U.S. chipmaker to hit the milestone Yahoo Finance. AMD shares jumped 9.6% to a record $613.92, fueled by surging demand for chips that power artificial intelligence systems TippsInsights. The rally reflects investor confidence that AMD can capture market share from rival Nvidia by selling server processors for AI inference and data processing, even as Nvidia's valuation towers at $5.4 trillion Yahoo Finance.
Meta's new AI agent app became the number one free app on Apple's App Store, sparking fresh investor interest in chips that support consumer-facing artificial intelligence Economic Times. AMD reported Q2 data-center revenue of $6.7 billion, more than double the prior year, with total revenue reaching $11.54 billion — up 50% year-over-year Economic Times. CEO Lisa Su said the company plans to double data-center sales by 2027.
Meta's Muse AI Agent hitting the top of Apple's free app chart caught Wall Street's attention. Jefferies analyst Jacky He noted that broader consumer adoption of AI agents demands more server CPU power. These systems need extra capacity for inference, orchestration, and infrastructure work. The moment sparked a wave of buying across chipmakers. Reuters reported that Intel shares rose 12% and Arm Holdings jumped 14% in the same session Reuters.
AMD's data-center segment has become its fastest-growing division. Q2 data-center revenue hit $6.7 billion, more than doubling from the year before Economic Times. Total company revenue reached $11.54 billion, up 50% annually. Meta, AMD's second-largest customer, accounts for about 5.5% of the company's annual revenue. This dependence on a handful of mega-scale cloud providers adds pressure on AMD to deliver results.
CEO Lisa Su pledged to double data-center sales by 2027, signaling confidence in sustained AI infrastructure spending. AMD has shifted from selling standalone chips to offering full platform stacks. These integrate server processors, AI accelerators, and networking equipment. The strategy lets AMD compete more directly with Nvidia in the lucrative data-center market Economic Times.
AMD's trillion-dollar milestone marks a symbolic victory. Yet Nvidia's valuation sits at $5.4 trillion — more than five times larger Yahoo Finance. AMD becomes only the fourth U.S. chipmaker to crack $1 trillion, joining Broadcom, Micron, and Nvidia itself Archynetys. The gap underscores Nvidia's dominance in AI graphics processors and its lock on the hyperscaler market.
Skeptics warn that AMD's rally depends on sustained spending from a small cluster of mega-cap firms like Meta and Microsoft Reuters. If those companies slow their data-center buildouts, AMD's growth story could falter. Still, AMD stock has gained over 180% year-to-date, reflecting strong investor belief in its AI chip future.
Falling Treasury yields and lower oil prices created favorable conditions for the chip rally. The 10-year Treasury yield dropped below 5% to 4.96%, reducing inflation concerns Reuters. The Philadelphia Semiconductor Index surged over 4% during the session. Lower rates boost the appeal of high-growth tech stocks because future earnings become more valuable in today's dollars.
