AMD Reaches $1 Trillion Market Value Amid AI Enthusiasm
On Monday, Advanced Micro Devices (AMD) briefly surpassed a market value of $1 trillion for the first time, thanks to a surge of excitement about artificial intelligence that propelled semiconductor stocks upward.
AMD shares rose about 9% that day, hitting a record high over $613, pushing the chipmaker’s valuation past the trillion-dollar mark. This increase made AMD the latest company in the semiconductor industry to achieve such a milestone, fueled by investor interest in firms providing the computing power necessary for AI.
The rise in AMD’s stock was partly driven by the popularity of Meta’s new Muse AI agent, which quickly became the top free iPhone app in the United States. AI agents require a substantial amount of CPU power for their operations, leading to heightened investor expectations for demand from chipmakers supplying these processors.
The momentum affected the entire semiconductor sector, with Intel shares climbing around 13% and Arm Holdings also seeing significant gains. Overall, the Philadelphia Semiconductor Index increased by approximately 3% as investors returned to AI-related stocks.
AMD now joins notable chipmakers like Nvidia, Broadcom, and Micron, who have reached or exceeded a $1 trillion valuation. Notably, Nvidia, the most valuable publicly traded company globally, has a market cap exceeding $5 trillion.
Other prominent companies that have crossed the $1 trillion threshold include Apple, Microsoft, Amazon, Alphabet, and Meta.
This recent uptick in AMD’s stock came just a week after widespread warnings about the potentially harmful effects of advanced AI sparked a global tech selloff. OpenAI’s CEO Sam Altman and Anthropic’s CEO Dario Amodei raised concerns about the risks posed by increasingly powerful AI systems, calling for a slowdown in development.
Nevertheless, technology firms continue to invest heavily in the infrastructure necessary for AI development. According to data from the Census Bureau, spending on private data-center construction reached a seasonally adjusted annual rate of $59.3 billion in May, which is a 23% increase compared to the previous year.
AMD has been challenging Nvidia in the AI computing space by speeding up product launches and broadening its offerings beyond individual processors to include complete systems that integrate chips, networking equipment, and other hardware.
Since the start of 2026, AMD’s stock has surged around 185%, greatly outpacing the Nasdaq’s approximate 16% gain during the same timeframe.
The overall stock market also saw an upswing on Monday, driven by falling oil prices and a decrease in Treasury yields, which helped alleviate some investor anxieties regarding inflation and borrowing costs.
