Arm’s upside is driven less by device unit growth and more by “value-per-design-win” expansion: more compute per device (AI features), more Arm content per server rack (host CPUs beside accelerators), and richer monetization (subsystems, higher-end cores, and ecosystem software). The base case assumes Arm keeps credibility as a neutral platform architect while steadily widening its performance-per-watt lead; that supports sustained, above-market revenue growth but also a gradual valuation de-risking as the story matures. Versus comparables, Arm stays more premium than merchant semiconductor vendors (e.g., Qualcomm) because of recurring
royalties, but it likely converges somewhat toward high-quality software/IP platforms (e.g., Synopsys/Cadence) as growth normalizes and open-
ISA pressure remains a ceiling on pricing power.
