On November 10, 2026, TSMC announced that its consolidated revenue for October was NT$586.89 billion, up 59.7% from a year earlier and 14.7% from the previous month. It topped August, the previous high, to become the highest monthly revenue of 2026. The advanced 2nm process accounted for 8% of wafer revenue in the most recent July–September quarter, but that figure differs in both period and scope from October's consolidated revenue. To connect the company-wide growth rate of roughly 60% to 2nm growth, you need to distinguish monthly revenue, the quarterly breakdown by process technology, and the company's guidance.
October revenue reaches NT$586.89 billion, a 2026 high
October revenue rose 14.7% from September's NT$511.857 billion. Compared with October last year (NT$367.473 billion), it was up 59.7%, so revenue grew strongly both month over month and year over year. These figures can be confirmed in TSMC's official announcement and the attached detailed materials. According to the company's 2026 monthly revenue list, August had the highest revenue from January through September. October surpassed that record, showing that the scale of sales has expanded further.
Cumulative revenue for January–October reached NT$4,485.617 billion, up 43.3% from the same period last year. Both the single month and the cumulative total show strong growth in TSMC's overall revenue. However, the 2026 monthly revenue figures are unaudited, and the company has published consolidated monthly revenue only since 2013. In addition, while the figures confirm that company-wide revenue increased, they do not show how much each process technology or application contributed to that growth.
Why the 8% 2nm share can't be applied to October revenue
The 8% share of wafer revenue for 2nm comes from TSMC's July–September 2026 results, announced on October 15. In that quarter, 3nm accounted for 33%, 5nm for 28%, and 7nm for 10%, bringing advanced processes of 7nm and below to 79% in total. In other words, the 8% for 2nm is a figure whose denominator is wafer revenue for July–September. It does not match the "October consolidated revenue" shown in the monthly announcement in either the period covered or the type of revenue.
Furthermore, the 8% is a share for the whole quarter, not a month-by-month ratio. Even though October revenue grew sharply, 2nm revenue did not necessarily rise at the same rate. Putting the October monthly announcement, the July–September results, and the October–December outlook side by side makes the differences among the figures clear.
| Disclosure item | Period / category | Reported figure / content | Revenue basis / denominator |
|---|---|---|---|
| October monthly revenue | October 2026 (actual) | NT$586.89 billion, up 59.7% year over year | Consolidated revenue |
| Revenue share by process technology | July–September 2026 (actual) | 2nm: 8%, 3nm: 33%, 5nm: 28%, 7nm: 10% | Wafer revenue |
| October–December outlook | October–December 2026 (guidance) | Revenue of US$52.3–54.3 billion. Expects strong demand for advanced technologies, including a ramp of 2nm volume production | Consolidated revenue (guidance) |
Thus, multiplying October's consolidated revenue of NT$586.89 billion by the 8% 2nm share from July–September does not yield October's 2nm revenue. Likewise, the 59.7% year-over-year growth rate is a separate metric from 2nm's revenue share or its contribution to growth. TSMC's October monthly announcement and attached materials do not include a breakdown of revenue by process technology, customer, or application. As a result, the disclosed materials as they stand do not allow us to determine how much 2nm or AI-related demand contributed to October's revenue growth.
That does not mean 2nm did not contribute to October's growth. It means the published monthly data cannot quantify its contribution. Nor is there information that separates changes in sales volume from changes in price, so it is difficult to pinpoint the cause of the revenue increase from the sales figure alone.
TSMC expects 2nm volume to ramp; quarterly results are the next focus
TSMC CFO Wendell Huang indicated at the July–September earnings announcement that strong demand for advanced technologies, including a rapid ramp of 2nm volume production, would support results in the October–December quarter. However, that was an explanation of guidance for the quarter, not an analysis of what drove October's growth, which became known afterward. The company's revenue guidance for October–December is US$52.3–54.3 billion, based on an exchange rate of 31.8 Taiwan dollars to the US dollar. October revenue is a single-month result in Taiwan dollars, whereas the guidance is a three-month forecast in US dollars, so currency and period must be aligned when comparing the two.
On profitability, TSMC expects a gross margin of 65–67% for October–December. The actual figure for the preceding July–September quarter was 66.4%. Gross margin is the share of revenue that remains as gross profit, and it is affected by factors such as manufacturing costs and product mix. However, because the monthly announcement does not disclose October's gross margin, rising revenue alone does not tell us whether profitability has improved.
In addition, 2nm was already included in wafer revenue for July–September. Interpreting October's revenue growth as the result of 2nm volume production starting that month therefore does not match the disclosed timeline. What TSMC anticipates for October–December is a further ramp of 2nm production that has already begun.
What the latest monthly announcement makes clear is the fact that TSMC's revenue has reached its highest level of 2026. How the ramp of 2nm volume production is affecting actual revenue mix and profitability cannot be seen from monthly data alone. In the October–December results to be published later, it will be important to check the share of wafer revenue from 2nm together with changes in consolidated revenue and gross margin.
