Figure 1 depicts the 2016 fabless company share of IC sales by company headquarters location. As shown, at 53%, the U.S. companies held the dominant share of fabless IC sales last year, although this share was down from 69% in 2010 (due in part to the acquisition of U.S.-based Broadcom by Singapore-based Avago).

Although Avago, now called Broadcom after its merger with fabless IC supplier Broadcom became official on February 1, 2016, has fabrication facilities that produce III-V discrete devices, it does not possess its own IC fabrication facilities and is considered by IC Insights to be a fabless IC supplier.

Figure 2 shows that in 2009, there was only one Chinese company in the top-50 fabless IC supplier ranking as compared to 11 in 2016.

Moreover, since 2010, the largest fabless IC marketshare increase has come from the Chinese suppliers, which held a 10% share last year as compared to only 5% in 2010.

However, when excluding the internal transfers of HiSilicon (over 90% of its sales go to its parent company Huawei), ZTE, and Datang, the Chinese share of the fabless market drops to about 6%.

European companies held only 1% of the fabless IC company marketshare in 2016 as compared to 4% in 2010. The reason for this loss of share was the acquisition of U.K.-based CSR, the second largest European fabless IC supplier, by Qualcomm in 1Q15 and the purchase of Germany-based Lantiq, the third largest European fabless IC supplier, by  Intel in 2Q15.

These acquisitions left U.K.-based Dialog ($1.2 billion in sales in 2016) as the only Europe-headquartered fabless IC supplier in the fabless top 50-company ranking last year (Norway-based Nordic Semiconductor just missed making the top 50 ranking with 2016 sales of $198 million).

There is also only one major fabless Japanese firm—Megachips, which saw its sales increase by 20% in 2016 (8% using a constant 2015 exchange rate), one major South Korean fabless IC company (Silicon Works), and one major Singapore-based (Broadcom Ltd.) fabless supplier.
