Record share price carries AMD across the threshold
AMD’s market capitalization briefly exceeded $1 trillion for the first time on September 21 after its shares reached a record $613.92. Reuters reported that the stock was subsequently up about 9% at $610. The milestone made AMD the fourth US chipmaker to cross the threshold, after Nvidia, Broadcom and Micron, amid investor demand for companies supplying AI-computing hardware. This is a market-price milestone rather than a measure of revenue, profit or cash generated, and the valuation can move back below the threshold as shares fluctuate.
