Fabless take 32.8% industry share

Typically, the sales growth rate of the fabless IC suppliers is better than that of the IDMs, and 2010 was the first year on record that IDM IC sales growth outpaced fabless IC company sales growth. That year, IDM IC sales grew 35% and fabless IC company sales grew 29%.

The difference between fabless IC supplier growth and IDM IC supplier growth has been especially pronounced over the past two years:

In 2019, driven by a collapse in the memory market, IDM IC sales plunged by 20% while fabless IC supplier sales declined only 1%.

In 2020, fabless IC company sales surged by 24% while IDM sales increased by only 8%.

Even after including the booming 2017 and 2018 IDM sales increases of 31% and 16% respectively, the 2010-2020 IDM CAGR was only 3%, one point less than the total IC market CAGR during this same timeperiod.

In contrast, the average annual growth rate of IC sales from the fabless/system IC companies was 8%, double the total IC market CAGR during this same 10-year timeframe.

Given the typical disparity in the annual growth rates in favor of the fabless/system IC suppliers versus the IDMs, it comes as little surprise that, except in 2010, 2015, 2017, and 2018 fabless/system IC companies increased their share of the total IC market (Figure 2).

In 2002, fabless/system IC company sales accounted for only 13% of the total IC market.

 With the memory market soaring in 2017 and 2018, a market in which the fabless companies have very little share, the fabless share of the total IC market shrank in both of those years.

However, with the memory market registering significant weakness in 2019, this situation reversed itself, with the fabless share of the total IC market jumping 4.1 percentage points that year to 29.9%.
