Executive Summary
Arm Holdings (ARM) is the most pervasive computing architecture in history. 99% of all smartphones run on Arm. The thesis is "The Shift to Data Center." As Power/Efficiency becomes more important than raw speed (due to AI's energy crisis), the Arm architecture is displacing Intel x86 in the Data Center (e.g., AWS Graviton, Nvidia Grace). Arm collects a royalty on every chip sold, making it the ultimate "Tax on Compute."
1. The Business Model: IP Licensing
Arm does not manufacture chips. It designs the "blueprints" (Instruction Set Architecture).
- License Fee: Companies like Apple or Qualcomm pay an upfront fee to access the blueprints.
- Royalty Fee: Arm collects a % of the sale price of every chip that ships. This is high-margin (95%+) software revenue.
2. The v9 Upgrade Cycle
Arm recently released its v9 architecture.
- Royalty Uplift: v9 chips command a 2x higher royalty rate than v8 chips. As the world upgrades to v9 (which includes new AI vector instructions), Arm's revenue will double even if unit volume stays flat.
- Sovereign AI: Every nation building its own AI sovereign cloud (using Nvidia Grace Hopper) is paying royalties to Arm.
3. The End of Wintel
For 30 years, Intel x86 + Windows dominance was unbreakable. That is over.
- Apple Silicon: The M1/M2/M3 chips proved that Arm is faster and more efficient than Intel.
- Windows on Arm: Microsoft is aggressively pushing Windows to run on Qualcomm (Arm) chips to compete with Mac battery life. If the PC market flips to Arm, Arm's TAM expands by 250 million units a year.
Risks to the Thesis
- RISC-V: This is the open-source alternative to Arm. China is investing billions in RISC-V to avoid paying royalties to a Western company. If RISC-V becomes "good enough," Arm's monopoly erodes.
- Qualcomm Lawsuit: Arm is suing its biggest customer (Qualcomm) over licensing disputes. A bad legal outcome could break the business model.
- China exposure: Arm gets ~20% of revenue from "Arm China," a joint venture with complex governance. Geopolitics is a constant threat.
Conclusion
Arm is the "Switzerland" of the semiconductor war. Whether Nvidia wins, or Apple wins, or Amazon wins, they all pay Arm.
