AMD crossed the $1 trillion market-cap milestone for the first time in September 2026, capping one of the more dramatic long-term comeback arcs in semiconductors.
The company was worth only about $2.3 billion in 2015. Since then, AMD has ridden a combination of CPU share gains, data-center momentum, and AI chip enthusiasm into the top tier of public-market valuations.
The chart shows the size of that re-rating: a long grind higher through the late 2010s, a pandemic-era surge, a 2022 reset, and then a sharp AI-driven climb into 2026.
The milestone matters because it reframes AMD's market identity. This is no longer just a cyclical chip recovery story. Investors are increasingly treating AMD as part of the core AI infrastructure trade.
