Key Highlights

  • Record results: Arm delivered a run of billion-dollar Revenue quarters in its 2026 financial year.
  • Royalty model: The company earns upfront licence fees plus royalties on every chip shipped using its designs, sometimes for a decade or more.
  • Higher-value designs: Advanced designs used in AI and data centers command higher Royalty rates than older smartphone chip designs.
  • Capital-light exposure: Arm profits from the AI boom without Manufacturing chips itself, benefiting regardless of which chipmaker ultimately wins.

Arm (NASDAQ:ARM) occupies an unusual and powerful place in the technology world: it designs the fundamental blueprints for chips that almost every smartphone, and a growing share of data-centre processors, are built upon, yet it makes none of them itself. Understanding how Arm earns money is one of the more rewarding exercises for anyone following the Nasdaq 100, because it reveals a Business model quite unlike the chipmakers around it.

What Arm Does

Arm is a British company, listed on the Nasdaq, that creates chip designs and the instruction sets that define how processors work. It sits in the technology sector. Rather than manufacture chips, it licenses its designs to companies such as phone makers and cloud providers, which build their own processors on Arm's foundations. It earns money in two ways: upfront licence fees and, crucially, royalties on every chip sold that uses its technology.

Licences Today, Royalties for Years

That royalty model is the heart of the Investment case. A licence signed today can generate royalty payments for a decade or more as chips based on the design ship in their billions. In its 2026 financial year Arm delivered record results, including a run of billion-dollar revenue quarters, driven by Demand for more advanced designs used in artificial intelligence and data centres, which command higher royalty rates than older smartphone chips. As the industry adopts newer, more complex Arm technology, the company earns more from each device, giving it a way to grow even in a mature smartphone market.

Why it Matters for the Nasdaq 100

Arm offers the index exposure to the AI boom through a capital-light model that profits regardless of which chipmaker ultimately wins. Because its technology is so widely used, its royalty trends are a broad barometer of activity across the chip industry, from phones to servers. Its move into data-centre and AI designs also positions it to benefit as computing shifts towards its architecture, making it a distinctive way to participate in the theme that dominates the benchmark.

The Risks to Weigh

Arm's valuation is high, reflecting big expectations that leave little Margin for disappointment. Royalty revenue depends on the health of end markets such as smartphones, which can be cyclical. Some large customers design so much themselves that they could, over time, reduce their reliance on Arm, and the company must keep its designs ahead to justify rising royalty rates. Geopolitical tension affecting the chip industry, and its exposure to a concentrated set of major customers, add further uncertainty.

A Tollbooth on Computing

Perhaps the most useful way to think about Arm is as a tollbooth on the movement towards more capable computing. Almost every mobile device, and an expanding share of other systems, pays Arm a small fee, and as those devices grow more sophisticated, the toll rises. This gives the company a rare kind of leverage: it can benefit from the industry's overall growth without shouldering the enormous cost and risk of manufacturing chips itself. The danger is that a tollbooth only works while everyone agrees to use the road. Should a major customer build a credible alternative architecture, or should the industry's direction shift, that privileged position could erode more quickly than its royalty streams suggest.

What to Watch Next

Readers should follow royalty revenue and the adoption of Arm's newer, higher-value designs, since the shift to more advanced technology is what lifts Earnings per chip. Licence signings hint at future royalties, so they are worth watching as a leading indicator. Progress in data centres and AI shows whether Arm can broaden beyond its smartphone heartland. Commentary on royalty rates reveals pricing power. Finally, keep the valuation firmly in view, because Arm trades on the promise of years of compounding royalties that must still materialise in full.

Collecting a Toll on Computing's Growth

Arm's royalty model gives it a rare kind of Leverage in the chip industry: it profits from growth almost regardless of who ultimately wins the underlying competition. That leverage is durable only as long as the industry keeps building on Arm's foundations rather than around them, which is why its push into data centers and AI, areas beyond its smartphone roots, matters so much to its long-term story.
