Propelled by 51% share of IDM sales and 65% share of fabless sales, U.S. companies captured 55% of the total worldwide IC market in 2019.

Regional marketshares of IDMs (companies operating wafer fabs), fabless companies, and total IC sales were led by U.S. headquartered companies in 2019, according to data presented in the recently released March Update to The McClean Report 2020.

Figure 1 shows U.S. companies held 55% of the total worldwide IC market in 2019 followed by the South Korean companies with a 21% share, down six percentage points from 2018.  Taiwanese companies, on the strength of their fabless company IC sales, held 6% of total IC sales, one point less than the European companies.

Figure 1

South Korean and Japanese companies have an extremely weak presence in the fabless IC segment and the Taiwanese and Chinese companies have a noticeably low share of the IDM portion of the IC market. Overall, U.S.-headquartered companies showed the most balance with regard to IDM, fabless, and total IC industry marketshare.
