TSMC October revenue jumps 59.7% to $18.4 billion on AI chip demand

Taiwan Semiconductor Manufacturing Co. just had the best month in its history. October revenue climbed 59.7% year over year to $18.4 billion.

A record month, by a wide margin

In local currency, TSMC booked consolidated revenue of NT$586.89 billion in October 2026. A year earlier, in October 2025, the figure was NT$367.47 billion.

The month-over-month jump was also hard to ignore. Revenue rose 14.7% from September 2026, when TSMC brought in NT$511.86 billion.

October also set a new monthly record. The previous high was NT$514.81 billion in August 2026, which means the record lasted about two months before falling.

Zoom out and the year looks similar. Revenue for January through October 2026 reached NT$4,485.62 billion, up 43.3% from the same stretch in 2025.

AI is doing the heavy lifting

The engine behind the surge is demand for advanced semiconductors. Artificial intelligence and high-performance computing customers are the main buyers driving it.

Shipments from TSMC’s leading-edge process nodes, including 2nm, 3nm and 5nm, were central to the growth. The 2nm technology is the freshest of the bunch. It was included in shipments during the third quarter, and it adds another premium product to TSMC’s lineup.

A third of the quarter in one month

TSMC’s guidance for fourth-quarter 2026 revenue sits between $52.3 billion and $54.3 billion. October alone accounts for approximately 34% to 35% of the midpoint of that range.

TSMC has also raised its full-year 2026 revenue growth forecast to around 44% in US dollar terms.

Markets took notice. TSMC shares rose in Taiwan, and the stock showed positive trends in US pre-market trading.

Taiwan’s export machine is running hot

TSMC’s numbers did not arrive in isolation. Taiwan’s broader export sector also posted strong results for October.

Overall exports from Taiwan increased 58.9% year over year in the month. Electronic component exports surged 61.4%, outpacing the headline figure.
