On Monday, September 21, Advanced Micro Devices (AMD) saw a 10% increase in shares, which caused the chipmaker’s market capitalisation to surpass $1 trillion for the first time. For the fifth consecutive trading session, the stock has maintained its winning streak.
AMD Joins $1 Trillion Club as AI Demand Fuels 180% Stock Surge in 2026
After Nvidia, Broadcom, and Micron, AMD became the fourth US chipmaker to surpass the $1 trillion valuation threshold as its shares reached a new high of $616 as a result of the rally.
With a market value of over $5 trillion, Nvidia crossed the threshold in 2023 and is currently the most valuable business in the world.
Following investors’ initial concerns that a slowdown in artificial intelligence development may eventually undermine demand for the processors, accelerators, and memory devices backing the industry, Monday’s surge continued a robust recovery.
Concerns about inflation and interest rates were lessened by the drop in energy prices, in addition to the increased optimism around semiconductor stocks. Additionally, the yield on the 10-year US Treasury fell below the carefully monitored 5% threshold, lessening the pressure that rising borrowing rates can put on growth-oriented technology equities.
Elevated bond yields can raise financing costs and make future corporate earnings less appealing, while rising oil prices can contribute to inflation predictions.
In order to compete with Nvidia’s offerings, AMD has hastened the release of its AI products and shifted from selling individual chips to providing whole systems that include processors, networking devices, and related hardware.
The growing demand for central processing units, which are used in conjunction with graphics processors in servers that do AI inference, is also helping the company. As a result, AMD has surpassed Intel in market share.
$1 TN Chip Club is expanded by AI boom
A number of multinational technology businesses have joined the $1 trillion market-capitalization club due to the growing demand for artificial intelligence and data-center infrastructure. Earlier in May, Samsung Electronics surpassed $1 trillion as chip and memory stocks continued to rise due to AI.
In a similar vein, SK Hynix surpassed $1 trillion in May 2026 due to the skyrocketing demand for high-bandwidth memory (HBM) chips, which are used in AI servers. As the need for AI data-center infrastructure increased dramatically this year, Micron Technology also became a member of the trillion-dollar club.
As of Monday, the market capitalisations of about 14 corporations exceeded $1 trillion, according to statistics gathered by LiveMint. Nearly every company in the trillion-dollar club is focused on technology, with the exception of Saudi Aramco, Eli Lilly and Company, and Berkshire Hathaway.
In 2026, AMD shares rise more than 180%.
Based on Monday’s high, the most recent rise has increased AMD’s year-to-date gains to 184%.
In the graphics processing unit (GPU) market for AI data centers, AMD currently lags behind competitor Nvidia by a significant margin, but investors are increasingly turning to AMD because they believe the AI opportunity is big enough to sustain multiple winners.
In recent years, there has been a significant increase in expectations for the chipmaker. Nvidia’s data-center sales have skyrocketed from roughly $15 billion annually to $194 billion last year since OpenAI’s ChatGPT sparked the artificial intelligence boom in 2022. This shows the size of the AI infrastructure sector, which AMD is currently actively pursuing.
