Advanced Micro Devices is the fourth American chipmaker to enter an elite valuation tier reserved for the sector's largest companies. The firm, headed by CEO Lisa Su, recently surpassed a market capitalization of $1 trillion, making it the first company in the world to achieve that milestone under the leadership of a female chief executive.

AMD joins a narrow group of domestic semiconductor firms to hit the valuation mark, following industry leaders such as Nvidia, which currently holds a market capitalization of $5.5 trillion.
