TSMC reported a sharp jump in quarterly revenue on 9 January 2026, fuelled by global demand for AI chips and its role as a supplier to Nvidia, now the world’s most valuable company.
Revenue for the final three months of 2025 rose 20 per cent year on year to about $33 billion, based on the chipmaker’s monthly updates. The number landed ahead of expectations, which is what happens when you sit in the middle of the hottest supply chain on earth.
For October to December 2025, Taiwan Semiconductor Manufacturing Co said revenue hit about NT$1.046 trillion (€28.4 billion), up 20.45 per cent year on year from roughly NT$868.46 billion (€23.6 billion). That was ahead of the NT$1.036 trillion analyst SmartEstimate, and it landed inside TSMC’s own Q4 revenue guidance of $32.2 billion to $33.4 billion.
TSMC’s 2025 revenue was reported at about NT$3.81 trillion (€103.5 billion), up 31.6 per cent. December eased off a bit versus November, with November 2025 revenue previously disclosed at NT$343.61 billion (€9.3 billion).
The proper stuff arrives on 15 January 2026, when TSMC reports full Q4 earnings, margins, profit, capex and its forward view. Until then, you are reverse-engineering from monthly sales and a lot of AI scene-setting.
The best hard detail on profitability and mix is still from the last full quarter it reported, Q3 2025. TSMC said Q3 revenue was NT$989.92 billion (€26.9 billion) and net income was NT$452.30 billion (€12.3 billion), with gross margin 59.5 per cent and operating margin 50.6 per cent.
In that Q3 disclosure, TSMC said three-nanometre was 23 per cent of wafer revenue, five-nanometre was 37 per cent, and seven-nanometre was 14 per cent, with advanced nodes of seven-nanometre and better accounting for 74 per cent of wafer revenue.
TSMC, senior vice-president and chief financial officer Wendell Huang said, “Our business in the third quarter was supported by strong demand for our leading-edge process technologies,” and he added that Q4 should see “continued strong demand” for the same.
For Q4 2025, TSMC guided gross margin at 59 to 61 per cent and operating margin at 49 to 51 per cent, which is unusually chunky for a company spending like mad on leading-edge capacity.
It matters what it said in October 2025 when it raised its full-year 2025 revenue growth outlook to the mid-30 per cent range in US dollar terms and kept 2025 capex up to $42 billion, because the market will judge 2026 on whether that spend has to climb again.
TSMC is often treated as a bellwether for the wider tech cycle, and this readout screams that AI spending is still alive and kicking. Job’s Mob still buys plenty of silicon from TSMC, but it is the Nvidia pipeline that has shoved the foundry into the loudest seat at the AI party.
