A decade ago, Advanced Micro Devices (AMD) was fighting for survival. It has now crossed a threshold few companies ever reach. On Monday, Sept. 21, 2026, AMD briefly surpassed a $1 trillion market capitalization for the first time.
Its shares surged nearly 10% to a record high above $616, lifting the company into rare territory. In doing so, AMD became only the fourth U.S. chipmaker to join the exclusive club, following Nvidia (NVDA), Broadcom (AVGO), and Micron (MU).
