Taiwan or Korea?
Taiwan or Korea: who is bigger in chips? Taiwan's top 5 chip companies are worth $2.5 trillion, Korea's $2.2 trillion.
Which side did you guess? 👇
We added up the five biggest chip companies in each place. By stock market value, on 9 Oct 2026.
Taiwan: about $2.5 trillion. TSMC alone is $2.07 trillion. That is 82% of the five. Then MediaTek, ASE, UMC and Nanya.
Korea: about $2.2 trillion. Samsung is $1.28 trillion. SK hynix is $892 billion. Together they are 98% of the five.
So Taiwan is one giant. Korea is two.
The catch: they mostly do different jobs. Taiwan builds the main chips. Korea builds the memory chips. An AI computer needs both.
Also: Samsung makes phones and TVs too, so not all of its value is chips. Stock values change every day.
