TSMC's September sales rise 54.6% year on year, driven by AI chip demand

Taiwan Semiconductor Manufacturing Co (TSMC), the world's largest contract chipmaker, posted net revenue of NT$511.86 billion (about $16.03 billion) in September, up 54.6% from the same month a year earlier. The figure was, however, down 0.6% from August, which tempers the narrative of unstoppable growth that has tended to accompany the company in recent quarters.

The article itself includes a relevant correction: the piece was updated to clarify that September sales did not reach a record high. That is an important nuance, because much of the media coverage of TSMC lately has emphasized successive all-time highs tied to the artificial intelligence boom, and it is worth not taking that framing for granted when the source itself explicitly contradicts it.

For the third quarter as a whole, TSMC's revenue came in at around NT$1.49 trillion, although the article does not break that figure down into year-on-year or sequential comparisons, so no reliable quarterly growth rate can be derived from it. The company is due to publish its full third-quarter results next week, which should provide more detail on margins, guidance and the specific weight of AI demand, aspects the source does not spell out.

On the market side, TSMC shares closed down 1.35% just before the monthly figures were released, a move the article does not attribute to any specific cause beyond the proximity of the sales data.

TSMC manufactures chips for customers such as Nvidia and Apple, two of the names most closely tied to the current artificial intelligence investment cycle, which explains why the market follows its monthly figures closely as an indirect gauge of demand for advanced chips. The article also notes that in September TSMC committed to adopting ASML's high numerical aperture extreme ultraviolet (High NA EUV) lithography machines, a key technology for producing more advanced manufacturing processes. With that step, TSMC joins Samsung Electronics among the customers taking on this latest-generation equipment, pointing to a continued race for miniaturization and performance in the most cutting-edge chips, largely destined for artificial intelligence workloads.

Taken together, the article offers a monthly snapshot of TSMC marked by notable year-on-year growth, a slight downward correction from the previous month, and a backdrop of technology investment (the adoption of High NA lithography) that reinforces its position as a central supplier in the AI supply chain. The full quarterly results, due the week after this publication, will be the next reference point for gauging whether this monthly slowdown is a one-off or the start of a trend.
