Advanced Micro Devices surpassed a $1 trillion market value as investors rewarded its expanding role in artificial-intelligence computing. AMD became the fourth U.S. chipmaker to reach the threshold, joining Nvidia, Broadcom and Micron. Shares rose 9.6% to $613.31, extending a 185% gain in 2026. AMD has moved beyond individual processors toward complete AI systems and has gained server CPU share from Intel, although its market optimism reflects substantial expectations for continuing AI infrastructure demand.
