20 Largest Semiconductor Stocks by Market Capitalisation

Nvidia, TSMC and Broadcom lead this snapshot of listed semiconductor and equipment companies by equity-market value. The table records the first 20 entries in CompaniesMarketCap’s semiconductor category, retrieved on 31 August 2026.

The figures measure whole companies. They do not isolate chip operations within diversified groups, and they are not a ranking by semiconductor revenue. That difference is particularly relevant for Samsung Electronics and Broadcom.

How the ranking was compiled

GMR transcribed the provider’s first 20 ranked companies and reported USD market values on the retrieval date. Amounts are shown in billions of US dollars, including values the provider displayed in trillions. The source order is retained; values have not been independently recalculated from exchange prices and share counts.

The universe follows the provider’s semiconductor category, including chip designers, manufacturers, memory companies and equipment suppliers. It excludes private companies and may differ from an exchange’s sector classification. A company appears once in the source ranking; an ADR or an additional listing is not added as a second company.

The retrieval date is not a common closing-price timestamp. Markets operate in different time zones, and prices, exchange rates and share counts can update at different times. Treat this as a dated provider snapshot rather than a synchronised valuation at one market close.

What equity value can and cannot tell you

Market capitalisation reflects the value investors assign to outstanding equity. It changes with prices and share counts and can move much faster than annual revenue or factory capacity. Currency movements also change a USD comparison of overseas companies.

A high market value can reflect expected growth and profitability. It does not by itself demonstrate a cheaper valuation, higher current sales or better future returns. Enterprise value and operating results answer different questions and should be considered separately.

Diversified companies make the boundary especially important. Comparing their whole-company equity values is valid as a stock-market exercise, but attributing the entire amount to semiconductor operations would be misleading.

Use the ranking alongside company and industry research

The semiconductor business-model guide explains the differences between designers, foundries, memory producers and equipment suppliers. Those differences are essential when comparing companies occupying adjacent positions in a size table.

GMR’s Nvidia, TSMC, Broadcom, ASML, AMD, Micron and Arm profiles provide routes into the company coverage. For ASML’s domestic operating environment, Dutch Business Review covers the Netherlands business and policy context.

This table is a research starting point, not an investment recommendation. The source updates continuously; the figures published here remain the dated snapshot until the next editorial review.
