Samsung: Customer, Rival and Foundry at OnceNarrow moat

Qualcomm (QCOM) — moat facet

Every input needed to replace Snapdragon sits inside Samsung, and Samsung keeps deciding not to.

Samsung buys Qualcomm's chips, builds a competitor to them, and manufactures both — and has done all three at once for more than a decade.

It keeps deciding not to, which is the best evidence Qualcomm has.

It is a customer at scale: Samsung was one of three customers each accounting for 10% or more of Qualcomm's consolidated revenue in fiscal 2025.1 It is a competitor through Exynos, its own application processor line, which it has developed since before Snapdragon dominated Android. And it is a foundry — one of the two that fabricate Qualcomm's parts.

The interesting fact is what Samsung does with that position, which is keep buying. Exynos exists, is competitive in most respects, and Samsung nonetheless uses Snapdragon across its flagship tier in most markets. A company that has every structural reason to self-supply — the design team, the fab, the volume, the incentive — has repeatedly concluded that the Qualcomm part is better for the phones it cares most about.

That is worth more as evidence than any market-share statistic, and it is why this relationship is rated the way it is: the merit case is being tested annually by the party best equipped to disprove it.

The vulnerability is that the same logic could reverse in a single product cycle, and Samsung would owe the royalty either way.2

Watch the flagship Galaxy chipset split by region, which is where Samsung expresses its judgement.

Moat trajectory: Holding steady

Samsung has bought Snapdragon for its flagship tier for years while shipping Exynos elsewhere, and the split moves by generation without trending.

The number that tests this moat
Reported
South Korea share of revenue
21% in fiscal 2025, from 20%

Samsung buys Qualcomm chips, makes its own Exynos alternative and manufactures chips for Qualcomm. The Korean share of revenue is the closest measure of how much Samsung still buys.
