Advanced Micro Devices shares rose more than 5% intraday on September 8, 2026, briefly reaching about $503 before settling near $500. The move lacked a single company-specific catalyst and coincided with gains in Micron, Nvidia and Intel as investors wagered that corporate AI-infrastructure spending can continue expanding. AMD entered the session after reporting Q2 2026 revenue of $11.54 billion, up 50% year-on-year, while data-center revenue climbed 107% to $6.72 billion and represented 58% of total sales. Non-GAAP earnings per share were $1.66, and the company guided for approximately $13 billion in Q3 revenue, or about 41% growth at the midpoint from Q3 2025. CEO Lisa Su has identified demand for EPYC server CPUs and Instinct GPUs (AMD's AI accelerators) as the main growth drivers. AMD has targeted more than 70% growth in server revenue over certain upcoming periods. The stock had traded between roughly $149 and $585 over the previous year and had tested $500 several times in 2026. Its market capitalization was estimated at $780 billion to $820 billion around the session. Goldman Sachs said memory stocks were breaking above summer downtrends, reflecting strong demand across semiconductors. Nvidia remains the leading supplier in AI GPU deployments, while Intel is seeking to rebuild its data-center position; AMD has established a credible second position, with some enterprise buyers using its Instinct lineup as an alternative that provides pricing leverage. The approximately $13 billion Q3 forecast will be the next major test when AMD reports in early November.
