Advanced Micro Devices briefly crossed a $1 trillion market capitalization for the first time on Monday, September 21, joining a small group of major U.S. semiconductor companies to reach the milestone.
Reuters reported that AMD shares were last up about 9.6% at $613.50 after touching a record high of $613.92 during the session. The $1 trillion valuation was an intraday market milestone and changes with AMD’s share price.
Reuters linked the rally to investor expectations around AMD’s expanding role in artificial-intelligence computing. The company has been broadening its AI offering beyond individual accelerators toward more complete systems that combine processors, networking equipment and other hardware.
Demand for CPUs used in AI-inference servers has also strengthened expectations that AMD can gain more share in data-center computing, while the company continues to compete with Nvidia in accelerators used for AI workloads.
The move came as semiconductor stocks rallied more broadly on renewed optimism around AI-related demand. The $1 trillion figure was an intraday market milestone recorded during the September 21 session and can move above or below that threshold as AMD’s share price changes.
