AMD's market capitalisation reached the USD 1 trillion threshold for the first time, marking a new high for the chipmaker's valuation. On 21 September, the company's stock climbed nearly 10%, touching an all-time intraday peak of USD 615.52.

The development follows by roughly a month a projection from AMD chief executive Lisa Su that the company's data centre revenue would double by 2027, driven by growing demand for AI computing. AMD's stock has climbed approximately 25% over the past five trading sessions.

The equity climbed approximately 185% across 2026, a pace that far exceeded the Nasdaq's roughly 15.8% advance over the same timeframe. AMD's recent stock gains build on a broadly positive 12-month period for the chipmaker, though its share price retreated the previous month following second-quarter results that exceeded both revenue and earnings forecasts. Market participants had anticipated more robust forward guidance from the company.

Part of the uptick reflects growing appetite among investors for companies positioned to capitalise on the build-out of AI infrastructure. NVIDIA holds a leading position in the AI computing sector, though AMD has been expanding its presence as a rival contender.

The chipmaker posted second-quarter earnings of USD 11.54 billion, a 50% increase compared with USD 7.69 billion recorded during the same period the previous year. Revenue from the Data Center division totalled USD 6.7 billion, representing growth of more than 100% compared with the prior year.

AMD's business operations have expanded beyond the sale of standalone processors. The chipmaker has been broadening its portfolio of integrated solutions — bundling processors, networking gear, and related hardware — as it competes for position in the artificial intelligence computing market against NVIDIA.

At the company's most recent earnings call, Su indicated that AMD anticipates its data centre division will expand by over 100% in 2027, with the server CPU category projected to post year-over-year growth exceeding 70%.

AMD's valuation crossing the USD 1 trillion threshold places the chipmaker among a small number of US semiconductor companies to have reached that level. AMD has joined NVIDIA, Broadcom, and Micron as the fourth chipmaker based in the United States to reach a market valuation of USD 1 trillion. Notwithstanding that achievement, AMD's overall valuation stands at a fraction of NVIDIA's, with the latter's market capitalisation exceeding USD 5 trillion.

AMD is considered among the leading competitors to NVIDIA in the graphics processing unit market for artificial intelligence applications. The most recent valuation reflects how closely tied investor focus remains to growing demand for AI processors and data centre infrastructure.
