Arm vs. Taiwan Semiconductor Manufacturing: Which Chip Stock Is a Better Buy in 2026?
Arm's royalty model compounds reliably across billions of devices. TSMC's factories build the chips that power every major AI system in the world. Both are essential, but only one is truly irreplaceable.
In 2026, investors are considering two major chip stocks: Arm (NASDAQ:ARM) and Taiwan Semiconductor Manufacturing (NYSE:TSM). Arm develops the intellectual property for chip design, while TSM physically manufactures these chips. Both companies stand to gain from the growing demand for artificial intelligence, but they differ in their business models and financials, presenting varying risks and rewards for retail investors.
Arm manufactures central processing units (CPUs) and compute platforms, licensing this technology to numerous leading semiconductor companies. Its latest annual report, submitted for the fiscal year concluding March 31, 2026, indicates that its energy-efficient designs are utilized in over 99% of smartphones sold worldwide. The company does not disclose specific information on customer concentration in its most recent filing, although it operates across a broad spectrum of markets.
