AMD crosses $1 trillion market capitalization amid AI chip rally
Advanced Micro Devices crossed a $1 trillion market capitalization on September 21, 2026, as shares surged alongside a broader rally in artificial intelligence and semiconductor stocks.
Advanced Micro Devices shares jumped nearly 10% on September 21, 2026, closing at an all-time high of $615.52 and lifting the company's market capitalization past $1 trillion. While most market commentators reported this was the company's first time reaching the milestone, Unusual Whales reported AMD reached the mark again, and Nairametrics reported that the crossing was brief during the session.[2][3][5][6][8][13]
The valuation makes AMD the fourth U.S. chipmaker to reach the $1 trillion mark, following Nvidia, Broadcom, and Micron, according to Coin Bureau and CoinMarketCap. Tom's Hardware separately noted AMD beat Intel to the trillion-dollar threshold and joined Nvidia, Broadcom, and SK hynix. The company's expansion has been propelled by data center operations, where revenue grew 107% in the previous quarter to represent 58% of AMD's total business.[1][10][11]
AMD's surge coincided with widespread gains across the technology sector on September 21, supported by easing oil prices and lower Treasury yields. The Nasdaq Composite gained 2.26% to a record close of 27,122, the Nasdaq 100 advanced 2.83%, and the PHLX Semiconductor Index rose 4.29%. Peer semiconductor and tech firms also advanced sharply, with Arm rising 17%, Intel climbing over 12%, Meta surging 11.34%, and Nvidia adding 2.30%.[4][7][9][12]
