TSMC scores its best month ever as October revenue jumps 59.7%

Taiwan Semiconductor Manufacturing Co. didn't just grow in October — it rewrote its own record book. Revenue jumped 59.7% year over year to $18.4 billion, the highest monthly tally the chipmaker has ever posted.

In local currency, TSMC booked NT$586.89 billion for October 2026, up from NT$367.47 billion a year earlier. The month-over-month climb was 14.7%, coming off September 2026's NT$511.86 billion. That haul smashed the prior monthly peak of NT$514.81 billion set in August 2026 — a record that survived roughly two months.

The year paints the same picture. Revenue from January through October 2026 hit NT$4,485.62 billion, up 43.3% from the same stretch in 2025.

What's fueling it: artificial intelligence and high-performance computing customers, who are the main buyers. Shipments from TSMC's leading-edge nodes — 2nm, 3nm and 5nm — drove the growth. The 2nm process is the newest piece of the lineup, and it entered shipments during the third quarter.

Management expects fourth-quarter 2026 revenue between $52.3 billion and $54.3 billion, with October alone accounting for roughly 34% to 35% of the midpoint of that range. TSMC also raised its full-year 2026 revenue growth forecast to around 44% in US dollar terms. Markets responded: shares rose in Taiwan, and the stock showed positive trends in US pre-market trading.

TSMC isn't carrying the momentum alone. Taiwan's overall exports climbed 58.9% year over year in October, while electronic component exports surged 61.4%, outpacing the headline number.
