Regional marketshares of IDMs (companies with wafer fabs), fabless companies, and total IC sales were led by U.S. headquartered companies in 2021, according to IC Insights.
U.S. companies held 54% of the total worldwide IC market (the combined total of IDM and fabless IC sales) in 2021 followed by the South Korean companies with a 22% share. Taiwanese companies, on the strength of their fabless company IC sales, held 9% of global IC sales as compared to a 6% share held by the European and Japanese suppliers (the Taiwanese companies first surpassed the European companies in IC industry marketshare in 2020).
The South Korean and Japanese companies have an extremely weak presence in the fabless IC segment and the Taiwanese and Chinese companies have a very low share of the IDM portion of the IC market. Overall, U.S.-headquartered companies show the most balance with regard to IDM, fabless, and total IC industry marketshare.
