The shift in TSMC's revenue mix is the clearest single measure of how thoroughly AI has restructured global semiconductor demand: High-Performance Computing — the segment anchored by AI accelerators for cloud data centers — rose 20% sequentially in a single quarter and now accounts for 66% of total wafer revenue, while smartphones, which generated the largest share of TSMC's revenue as recently as 2022, fell to just 22%. Gross margin climbed to 67.7%, above the company's own guidance ceiling, reflecting pricing power that comes from holding roughly 73% of the global advanced foundry market with no credible near-term challenger for the customers that matter most.
Advanced process nodes drove nearly all of that shift: the 3-nanometer process accounted for 30% of wafer revenue, the adjacent 5-nanometer node contributed 33%, and combined with 7nm production, nodes at 7nm and below represented 77% of all wafer revenue. TSMC Chairman and CEO C.C. Wei said "our conviction in the multi-year AI megatrend remains very high," noting that agentic AI applications are expanding silicon requirements across CPUs, GPUs, and other chip types — and that TSMC's edge comes from technology leadership and manufacturing expertise rather than subsidies or capital spending alone, since "there is no shortcut" for competitors trying to match its leading-edge capabilities.
For Q3, TSMC guided revenue between $44.6 billion and $45.8 billion, implying roughly 37% year-over-year growth, with 2-nanometer production ramping and CapEx for the year raised to $60-64 billion from a prior $52-56 billion range — confirming that the AI infrastructure spending cycle many expected to plateau in 2026 has instead accelerated.
