Arm designs the basic blueprints for computer chips and licenses them to other companies, earning money whenever those chips are sold.
Arm is the company behind the brains inside almost every smartphone on Earth. It doesn't manufacture chips itself. Instead, it designs the fundamental architecture — the instruction set and the blueprints for processor cores — and licenses those designs to chipmakers like Qualcomm, Apple, Samsung, and MediaTek, who build them into their own silicon. When you tap your phone screen, the processor carrying out your commands is almost certainly built on Arm's design. The same is increasingly true of cars, smart home devices, and data center servers.
The business model is elegantly simple. Arm charges customers an upfront license fee to access its designs, then collects a small royalty every time a chip containing Arm technology ships. That royalty is a tiny fraction of the chip's price, but multiplied across billions of chips a year, it adds up. In its fiscal year ending March 2025, Arm reported about $4 billion in revenue, with royalties making up the majority and growing steadily. The upfront license fees, meanwhile, are lumpier and depend on how many new customers sign up and how ambitious their projects are. What makes Arm strong is that its architecture is already baked into the world's software. Developers write apps for Arm-based chips because that's what phones use, and chipmakers use Arm because that's what software runs on. This feedback loop is hard to break. Arm's main vulnerability is that some big customers — most notably Apple and Qualcomm — have the resources and ambition to design more of their own cores, reducing their reliance on Arm's blueprints over time. There's also the long-running legal fight with Qualcomm over licensing terms following Qualcomm's acquisition of chip startup Nuvia, a dispute that has kept lawyers busy and highlighted how much is at stake in Arm's customer relationships.
Arm listed on the Nasdaq in September 2023, returning to public markets after being owned by SoftBank. The company is spending heavily on research and development to push into new areas, particularly data center chips and AI processors, where it wants to challenge the dominance of x86 architecture. It doesn't pay a dividend and doesn't buy back shares in any meaningful way; the cash it generates goes back into designing the next generation of chip blueprints. The bet is that as AI spreads into everything from cars to factory equipment to cloud servers, more of those chips will carry Arm's DNA inside.
