The numbers keep getting bigger. TSMC just revised its global semiconductor market forecast upward from $1 trillion to over $1.5 trillion by 2030 and the reason is one word: AI. Speaking at TSMC’s 2026 Technology Forum, executives painted a picture of an industry growing faster than anyone predicted just two years ago, driven almost entirely by artificial intelligence and high-performance computing demand.
The breakdown tells the story clearly. AI and HPC are expected to represent 55% of the entire semiconductor market by 2030, roughly $825 billion of that $1.5 trillion figure alone. Smartphones, which once dominated chip demand conversations, contribute only around 20%. Automotive chips account for 10%. The hierarchy has completely shifted.
The raw growth numbers are staggering. Demand for AI accelerator wafers has grown 11 times between 2022 and 2026. TSMC’s CoWoS advanced packaging capacity, the technology connecting AI GPUs with high-bandwidth memory, is growing at over 80% CAGR through 2027. Capacity for 2nm and next-generation A16 chips is expanding at 70% CAGR from 2026 to 2028.
To keep pace, TSMC is adding nine new fab phases and packaging facilities in 2026 alone. In Arizona, four fabs are at various construction stages with output growing 1.8x year-over-year. Japan’s second fab upgraded to 3nm. Germany’s fab is on schedule.
For context the chips inside your next iPhone, Samsung flagship, and every AI data center on the planet all run through TSMC.
The AI era isn’t coming. According to TSMC, it’s already here and it’s worth $1.5 trillion.
