TSMC reported September revenue of T$511.86 billion (NT$), bringing third-quarter revenue to approximately T$1.49 trillion, according to figures carried by Moomoo. The monthly result makes September one of the strongest single months in the company's history and confirms that demand for leading-edge foundry capacity has not cooled through the second half of 2024.

How large is the Q3 figure in context?

The T$1.49 trillion quarterly haul is the number investors and supply-chain analysts watch most closely, because TSMC's revenue is the most direct proxy for global appetite for advanced silicon. Apple, NVIDIA, AMD and Qualcomm all buy wafers from the company, spanning process nodes from mature N28 capacity up through N5, N4 and the ramping N3 family.

September's T$511.86 billion contribution to that total signals that wafer shipments held up firmly through the final month of the quarter. That matters because TSMC's quarters are not flat: smartphone and high-performance-computing customers concentrate tape-outs, stock builds and product launches around specific windows, and September typically reflects fulfillment ahead of the autumn device cycle.

What does the revenue mix tell buyers?

TSMC does not break out node-level detail in its monthly sales disclosures — the company publishes full segment and node revenue splits only in its quarterly earnings materials, which arrive later in October. The headline figures therefore describe total foundry billing, not the performance of any single process or customer program.

Even so, the magnitude of the September and Q3 numbers gives buyers of advanced-node capacity a clear signal: allocation at the front end remains tight and expensive. Foundry pricing for leading-edge nodes has been rising as TSMC funds its capital program, and strong reported revenue is consistent with those higher wafer prices sticking.

Where does the money go?

TSMC's revenue strength feeds directly into its capacity build-out. The company has committed to capital expenditure in the tens of billions of US dollars annually across:

• Advanced node fabs in Taiwan, including N3 and next-generation N2 development
• Overseas expansion, with fabs under construction in Arizona, Japan and Germany
• Advanced packaging capacity for AI accelerators, where CoWoS supply remains a bottleneck for customers including NVIDIA

Sustained revenue at this scale underwrites that roadmap. Every quarter above roughly T$1.4 trillion strengthens the case that the international fab strategy — politically driven as much as commercially — remains funded by the core Taiwan business.

What comes next?

The market's attention now shifts to TSMC's quarterly earnings call later in October, where the company will disclose revenue by node and platform, gross margin, and any revision to full-year capex and 2025 guidance. If the Q3 top line lands with margins intact, expect management to face questions on CoWoS packaging expansion, overseas fab schedules and pricing for N2, which is slated for volume production heading into 2025. On the strength of these monthly figures, the commercial picture favors the foundry: demand at the leading edge continues to outrun supply, and TSMC's pricing power looks set to carry into next year.
