ARM's Dual-Sided Network Effect Solidifies Its Dominance

Arm Holdings plc's ARM competitive edge rests on a powerful dual-sided network effect that links software creators and hardware makers in a self-reinforcing loop.

The company’s architecture has become the default choice for device manufacturers because it already supports a massive universe of applications across Android, iOS, Windows, and Linux ecosystems. This existing software breadth gives hardware producers confidence that chips based on ARM’s designs will integrate smoothly with global tools, platforms, and services, making adoption a low-risk, high-benefit decision.

A Flywheel With Unmatched Momentum

On the other side, developers are drawn to ARM because their applications immediately gain reach across an enormous installed base of devices. Every new hardware partner expands ARM’s footprint further, strengthening the incentive for developers to keep building for the platform. This creates a flywheel effect: more developers attract more manufacturers, which then bring in even more developers. Over time, this reinforcing cycle has grown into a deep moat that competitors struggle to penetrate.

A Virtual Lock on Mobile Computing

This network-driven advantage has led to an extraordinary outcome: ARM effectively controls mobile CPU architecture. With its IP embedded in nearly every smartphone worldwide, the company operates from a position of unmatched scale, making its lead in mobile computing extremely difficult for rivals to challenge.

Peers: NVIDIA and Qualcomm

NVIDIA NVDA competes with ARM in edge computing and AI-driven device workloads. NVIDIA benefits from its own ecosystem, but NVIDIA lacks ARM’s mobile reach. Even where NVIDIA pushes into low-power processors, the breadth of ARM compatibility limits NVIDIA’s ability to displace existing standards.

Qualcomm QCOM remains one of ARM’s most essential partners, yet also a peer, because Qualcomm builds mobile chips around ARM cores. Qualcomm depends heavily on ARM’s architecture, and Qualcomm’s success in smartphones reinforces ARM’s position. Yet Qualcomm continues investing in custom designs to diversify, although ARM’s scale still keeps Qualcomm aligned with the platform.
