TSMC is the world’s largest and most advanced process foundry, fabless chip design companies almost all rely on TSMC foundry, including Apple, AMD, Qualcomm, MediaTek, NVIDIA and so on, of which Apple deservedly became TSMC’s number one customer, and the degree of dependence is increasing, nearly 40% of revenue in 2021 from Apple.
According to, market research firm Strategy Analytics data, TSMC’s revenue share from Apple has gradually increased in recent years. Among TSMC’s top 10 customers, Apple’s share of which revenue also increased from 25% in 2016 to 37% in 2021.
You can also see from the chart above, Apple contributed $14.8 billion in revenue to TSMC in 2021, all other customers contributed revenue of just $42 billion, after all, Apple iPhone/iPad A series and M1/M2 series chips are TSMC foundry, and are the most advanced 7nm, 5nm process, high prices, high production, revenue share is naturally higher than other Manufacturers a cut.
Time back in 2019, Huawei was TSMC’s second largest customer when Apple’s revenue accounted for about 23%, and Huawei accounted for 14%, if there is no U.S. restrictions, Huawei in recent years will also have a large number of self-research chips to TSMC foundry, but unfortunately after the Kirin 9000 chip has been out of print.
After this, TSMC’s reliance on Apple continues to rise, taking into account the second half of the 2022 chip market from a shortage to surplus, many customers will cut orders, while Apple is less affected by the decline in phone and PC sales, is expected in TSMC’s revenue share may further increase.
