AMD Achieves Historic $1 Trillion Market Cap in AI-Driven Rally
Advanced Micro Devices (AMD) etched its name in history on Monday, September 21, 2026, becoming the fourth U.S. chipmaker to exceed a $1 trillion market capitalization. This landmark was once considered years away. Shares escalated nearly 10% to an all-time intraday peak of $615.52, concluding a remarkable five-session rally of approximately 25% and propelling AMD’s year-to-date gains to over 185%.
The dramatic surge was fueled by escalating investor confidence in AMD’s pivotal role as a leading supplier of AI computing hardware. The company reported a second-quarter 2026 revenue of $11.54 billion, marking a 50% year over year increase. Its Data Center segment alone generated $6.7 billion, a staggering 107% annual increase. AMD’s CFO has projected a $2 trillion to $3 trillion total addressable market for AI silicon by 2030.
AMD now stands alongside Nvidia (currently valued at approximately $5.4 trillion), Broadcom, and Micron in the exclusive club of trillion-dollar chipmakers. Notably, rival Intel has not yet achieved the same milestone, with AMD’s valuation now running roughly $352 billion ahead of Intel’s. Wall Street analysts remain divided on whether the stock’s elevated valuation — trading at over 55 times forward earnings — is sustainable. However, few are betting against CEO Lisa Su’s proven track record.
