TSMC reported September revenue of T$511.86 billion, bringing third-quarter revenue to T$1.49 trillion, according to figures released by the company.

The September number closes out a quarter in which Taiwan's dominant contract chipmaker recorded T$1.49 trillion in total sales. The monthly figure of T$511.86 billion represents the final data point investors and analysts will use to assess the quarter before TSMC's formal earnings report.

What do the numbers show?

The headline figures break down simply:

• September revenue: T$511.86 billion
• Q3 revenue (July–September): T$1.49 trillion

TSMC discloses monthly revenue under Taiwanese reporting requirements, which obliges listed companies to publish sales figures ahead of full quarterly results. These monthly disclosures give the market an early read on demand before the company publishes detailed margin, capacity and guidance data.

Why does monthly revenue matter for the market?

TSMC sits at the center of the global semiconductor supply chain. Its revenue trajectory functions as a proxy for demand across smartphones, high-performance computing and automotive electronics, since customers ranging from Apple to Nvidia depend on its fabrication capacity.

A September figure of T$511.86 billion, accumulating to T$1.49 trillion over the quarter, gives analysts the top-line picture roughly two weeks before the company's quarterly earnings call. At that call, TSMC will layer in gross margin, capital expenditure and forward guidance — the numbers that typically move the stock.

What happens next?

Investors will now watch the scheduled Q3 earnings release, where TSMC management will contextualize the T$1.49 trillion revenue figure with profitability data and fourth-quarter outlook. Until then, the monthly and quarterly top-line numbers stand as the firmest available measure of how the world's largest contract chipmaker performed through the third quarter.
