AMD hits $1 trillion, trades at 55.6× vs Nvidia's 18.7×

The valuation gap between AMD and Nvidia is the story here. AMD only recently crossed the $1 trillion mark, but its forward multiple already sits well above Nvidia's, even though Nvidia is the larger and faster-growing business. The article's comparison puts AMD at about 55.6 times forward earnings versus 18.7 times for Nvidia on an S&P Global basis updated September 24 — the challenger carries the richer multiple. That flips the usual "buy the leader" logic, and makes the choice very different from a year ago.

AMD's case rests on its smaller base. EPYC server CPUs are gaining ground, Instinct deployments are scaling, and Helios gives AMD a rack-level offering. Anthropic has agreed to deploy up to 2 gigawatts of MI450-series systems, with the first gigawatt expected to begin deployment in the first half of 2027. If ROCm keeps improving and cloud customers increasingly demand a second supplier, AMD can compound earnings faster than its current size suggests — the bet the premium multiple implies. Nvidia's bear case is the mirror image: hyperscaler custom silicon, AMD and other architectures can chip away at a profit pool that has attracted enormous competition. Yet Nvidia retains CUDA, a broader full-stack platform and much higher margins, while its lower forward multiple already allows for more normalization.

What the outcome hinges on is whether AMD's potential share gains actually materialize at scale, and whether the premium multiple survives the wait. If ROCm adoption stalls or cloud customers treat AMD as a secondary supplier rather than a true alternative, the valuation gap could compress. If Anthropic's gigawatt-scale MI450 deployment begins on schedule in the first half of 2027 and other cloud customers follow, AMD's earnings growth could justify the richer multiple — a test the company has yet to pass.
