TSMC reported NT$511.86 billion in consolidated revenue for September 2026 on October 8. That was 54.6% more than in September 2025, but 0.6% less than in August 2026, according to the company’s release.

September’s revenue in context

The two comparisons use different baselines: September revenue rose sharply year over year while edging down from the previous month. Revenue measures sales; it is distinct from profit, which accounts for expenses.

January–September 2026NT$3,898.73 billion+41.1%

TSMC’s revenue for January through September was NT$3,898.73 billion, up 41.1% from the same nine months in 2025. The cumulative total puts September’s result within a longer period of year-over-year growth, even as the monthly figure slipped from August.

CNBC corrected its report to say September sales did not reach a record high. The outlet also described TSMC as benefiting from demand for advanced AI chips. That is industry context, not a cause TSMC attributed to September’s increase: the figures are consolidated revenue totals, rather than a breakdown assigning growth to AI demand (CNBC).
