TSMC's record quarter: $46.7B Q3 revenue as September sales surge 54.6% on AI chip demand
TSMC reported a record NT$1.49 trillion ($46.7B) in third-quarter revenue on October 8, with September sales up 54.6% year over year — the latest hard proof that AI infrastructure spending is converting into real chip revenue, even as the stock slipped before the release.
TSMC reported Thursday that consolidated September revenue rose 54.6 percent from a year earlier to NT$511.86 billion (about $16.1 billion), per the company's monthly release quoted by ANI. The figure caps a record third quarter for the world's largest contract chipmaker — and is the latest hard evidence that AI infrastructure spending is converting into real, billed chip revenue rather than just capex promises.
The quarter in one number
Calculated from the monthly releases, July–September revenue came to roughly NT$1.49 trillion ($46.71 billion), up about 50 percent year over year — a single-quarter record, Reuters reported Thursday. That beat the LSEG SmartEstimate of NT$1.46 trillion drawn from 19 analysts, and landed above TSMC's own July guidance of $44.6 billion to $45.8 billion.
The company will report full third-quarter earnings on October 15, when analysts expect net profit of roughly NT$740.8 billion — up 64 percent on the year, per the same LSEG estimate. Cumulative revenue for the first nine months of 2026 reached NT$3,898.73 billion, up 41.1 percent from the same period in 2025.
Shares fell anyway
TSMC's Taipei-listed shares closed down 1.35 percent on Thursday — but that decline happened before the revenue figures were released, so it was not the market's verdict on them. The broader Taipei market was also down about 1 percent, and TSMC shares have climbed 64.5 percent so far this year: expectations going into the release were sky-high.
Why the monthly number matters
TSMC's monthly filings occupy a rare spot in the AI trade: they are not projections, guidance, or capex budgets — they are chips already built, shipped and billed. The company makes the vast majority of the world's most advanced logic chips, including the GPUs inside Nvidia's accelerators and custom AI silicon for the big cloud providers, and supplies Apple as well. When its monthly sales move this far, something real happened upstream, not just a slide deck.
That is also why the timing does work. ASML reports its own third-quarter results on October 14, and TSMC follows with full earnings on October 15 — this was the last hard data point before both.
What to watch
Two things to listen for on October 15: whether gross margins hold to the 65–67 percent the company guided, and what management says about fourth-quarter demand and the 2026 outlook. One caveat on today's number — the release reports total company revenue, not a separately disclosed AI-chip figure, so the 54.6 percent measures growth across the whole business rather than isolating how much came specifically from AI demand. The composition comes next week.
