TSMC's September revenue jumps 54.6% to NT$511.9 billion on AI chip demand

Taiwan Semiconductor Manufacturing Company (TSMC), the world's largest contract chipmaker, reported consolidated revenue of about NT$511.86 billion for September 2026, up 54.6% from September 2025. The company released the figure on Thursday, October 8, 2026. September sales were 0.6% lower than in August, when revenue reached about NT$514.81 billion, the first month ever above NT$500 billion. In US dollar terms, September revenue was roughly $16 billion. Revenue for July to September came to about NT$1.49 trillion, about 51% higher than a year earlier.

TSMC makes the most advanced processors for companies such as Nvidia, Apple and AMD, so its monthly sales are one of the clearest real-time readings of demand for AI hardware. A 54.6% jump from a year earlier, at a revenue level already above NT$500 billion a month, shows that orders for AI accelerators and the advanced chips around them are still rising fast.

The figures land in a nervous week for AI stocks. On the same day, shares of Nvidia, Oracle and CoreWeave fell after a report put OpenAI's annualized revenue well below what investors had assumed. TSMC's numbers point the other way: whatever the debate about how quickly AI companies can turn spending into profit, the money for chips is still being spent. The slight dip from August is small and monthly sales often move with shipment timing, so it does not, on its own, signal a slowdown.

The growth also shows how concentrated TSMC's business has become. With about two-thirds of revenue coming from high-performance computing, the company's fortunes are now closely tied to data-centre investment by large cloud and AI companies. That brings strong growth while spending lasts, but also exposure if those buyers pull back.

For Indian businesses, TSMC's results are a reference point for the semiconductor plans India is pursuing. They show the scale and the pace of investment that leading chipmaking requires, and they underline how much of the world's AI supply chain still runs through a single company in Taiwan.

Short-term: The numbers give investors evidence that AI chip demand stayed strong through the third quarter, which may steady sentiment in chip stocks after this week's sell-off.

Long-term: Sustained growth at this pace supports TSMC's heavy spending on new factories and advanced packaging, and keeps pressure on other countries to build their own chip supply chains.

Who is affected: Chip designers such as Nvidia, AMD and Apple that rely on TSMC; cloud and AI companies buying the chips; investors in semiconductor stocks; and governments, including India's, building domestic chip industries.
