The company-wide sales figures offer an AI-supply-chain checkpoint ahead of quarterly earnings, not a separate measure of AI-chip revenue.
Listen to this story
TSMC’s September revenue gives investors a strong annual growth reading but no further month-to-month increase, ahead of the company’s quarterly earnings release the following week. The roughly NT$1.49 trillion in third-quarter sales underscores the scale of the chipmaker’s business, which supplies companies including Nvidia and Apple. But September’s figures cover total revenue, not AI-chip sales specifically, so they do not show how much of the growth came from AI demand.
September revenue was NT$511.86 billion, or about $16.03 billion, up 54.6% from a year earlier and down 0.6% from August.
TSMC shares fell 1.35% before the sales figures were released; that decline was not a market reaction to the disclosure.
The next checkpoint is TSMC’s third-quarter earnings report, which will provide more financial detail than the monthly revenue release.
TSMC’s September sales remained far above last year’s level, even as they edged below August’s. The chipmaker reported revenue of NT$511.86 billion ($16.03 billion), according to CNBC’s October 8 report. Sales rose 54.6% year over year and fell 0.6% month over month, providing a new revenue checkpoint before the company’s quarterly earnings report the following week.
The two growth rates answer different questions. The annual comparison measures September against the same month in 2025, showing how much larger sales have become over a year. The monthly comparison measures September against August 2026. For readers judging momentum, one captures the longer change in revenue; the other captures its latest direction. September delivered strong annual growth without another month-to-month increase.
TSMC’s shares closed 1.35% lower before the monthly figures were released. That timing is important: the trading decline preceded the disclosure, rather than representing investors’ response to the newly published September numbers.
TSMC’s sales for the full quarter reached approximately this amount.
TSMC is the world’s largest contract chipmaker, with Nvidia and Apple among its customers. Those customer relationships put the manufacturer behind more than one company’s products, making its revenue relevant beyond its own business. CNBC identifies TSMC as a major beneficiary of surging demand for advanced chips used in AI.
September’s figure nevertheless covers TSMC’s overall revenue, not a separately disclosed AI-chip total. The distinction limits what the annual increase can tell readers: it measures growth across the manufacturer’s business, rather than isolating how much additional revenue came from AI demand.
TSMC is scheduled to report third-quarter earnings the week after the October 8 disclosure. The revenue total establishes the scale of sales for the quarter, but it is not a quarterly profit announcement. The forthcoming earnings release is the next financial checkpoint for the company.
