Semiconductors are the chips inside phones, cars, factories and data centers. MoatScope covers 90 companies in the industry: chip designers, manufacturers, foundries, licensors, and packaging and test specialists. Seven have a wide moat, 40 a narrow moat and 43 none. That makes just over half of the industry moat-rated, against roughly three in ten across MoatScope's whole universe.
How the industry makes money
Chip companies earn their returns in three different ways. Designers such as NVIDIA create the chips and the software around them, then hand manufacturing to others; their economics depend on how long a design stays in demand and how much customers build on top of it. Manufacturers carry the cost of fabrication plants: TSMC is a pure-play foundry that makes chips to order for other companies, while Texas Instruments and Analog Devices run their own specialized factories. Licensors such as Arm and Universal Display earn royalties on intellectual property that other companies build into their products.
Where the moats are
Across the 47 companies with a moat, two sources dominate: switching costs, found in 39 of them, and intangible assets such as patents, architectures and design libraries, found in 36. Cost advantages, efficient scale and network effects are rarer, but they show up in the strongest franchises. The seven wide-moat companies each combine at least two sources.
- NVIDIA: its CUDA software platform and GPU architecture, reinforced by switching costs and a developer ecosystem that grows more valuable as it grows.
- TSMC: process technology, scale and customer switching costs that make it the manufacturer of choice for the most advanced chips.
- Broadcom: switching costs and scale across networking, custom accelerators, broadband and wireless chips, alongside an infrastructure-software business.
- Arm: it licenses the processor architecture much of the industry builds on, and the ecosystem around that architecture is the moat.
- Texas Instruments and Analog Devices: analog chips designed into customers' products and rarely swapped out, broad catalogs, and manufacturing cost advantages.
- Universal Display: the patents and materials that phosphorescent OLED displays depend on.
Most of the 40 narrow-moat companies, among them Qualcomm, AMD, Micron, NXP, Microchip, ON Semiconductor and Monolithic Power, rely on the same two sources in a thinner form: products designed into customers' systems and the intellectual property behind them.
What wears moats down
Leadership in chips is rarely permanent. Three forces do most of the damage: architecture shifts that make a product line less relevant, manufacturing setbacks that let a rival pull ahead on process technology, and deep inventory cycles that wipe out pricing power for chips customers can easily swap. Memory and commodity parts feel the cycle most; chips that are designed into long-lived products feel it least.
What the quality scores say
The seven wide-moat companies score between 72 and 86 on MoatScope's quality scale. A moat and quality are related but not the same thing: Monolithic Power and Qualcomm reach the same range with narrow moats, while several narrow-moat names score far lower because their earnings swing with the cycle.
What to watch
- Customer concentration: when a handful of large buyers drive demand, a single design win or loss moves results sharply.
- Process leadership at the foundries, which decides who can build the most advanced chips and at what cost.
- Export controls and trade policy, which shape where chips and chipmaking tools can be sold.
- Inventory cycles: order cuts tend to show up first in memory and commodity parts.
