AMD Stock Hits $1 Trillion Milestone Amid 190% Rally in 2026

AMD stock has surged over 190% in 2026, reaching a market capitalization of $1.03 trillion, driven by strong demand for its Helios AI server system. While AMD shares closed at $630.63 on September 25, Nvidia remains significantly larger with a $5.42 trillion market cap. Despite AMD's rapid growth and record second-quarter revenue of $11.54 billion, Wall Street analysts currently favor Nvidia, projecting higher upside potential for the company due to its massive profit margins and lower P/E ratio compared to AMD's 162.
