TSMC August Revenue +53%: What Monthly Data Can't Tell You
TSMC's August revenue rose 53.3% from a year ago, and within hours it was being read as proof of a 2nm or AI surge. The monthly release cannot carry that weight. It is excellent for tracking the quarter against guidance and nearly silent on what drove it.
KEY TAKEAWAYS
- August revenue was about NT$514.81B, up 10.1% month on month and 53.3% year on year. Jan-Aug revenue rose 39.3%.
- July plus August total NT$982.4B, 67-69% of Q3 guidance converted at TSMC's assumed 32 NT$ per dollar (author calculation).
- Monthly releases carry no node, customer, product or margin detail, so 2nm and AI contributions cannot be pinned down from them.
The number, cleanly stated
TSMC reported consolidated August revenue of approximately NT$514.81B on Sep 10, up 10.1% from July and 53.3% from August 2025. Revenue for January through August reached NT$3,386.87B, up 39.3%.
Units trip people up. The NT$514,806 million quoted in some channels, NT$514.81B and roughly 5,148억 in Korean notation are the same figure. Growth rates are rounded to one decimal, so anything back-solved from them, such as August 2025 revenue of about NT$335.8B, is approximate.
What monthly revenue is good for: tracking guidance
In July TSMC guided Q3 revenue to US$44.6-45.8B, with its margin guidance based on 32 NT$ per dollar. At that rate the range is NT$1,427.2-1,465.6B. July (NT$467.6B) and August (NT$514.8B) together cover 69% of the low end and 67% of the high end.
September would need NT$444.8-483.2B, which means it could come in 6-14% below August and still land inside the converted range. Because guidance is in dollars, every NT$1 move in the exchange rate shifts the target by about NT$45B. Q2's implied rate was about 31.6, and NT$ growth runs ahead of dollar growth when the currency weakens: Q2 was +36.0% in NT$ against +33.7% in dollars.
Two months versus the first half
Averaging the quarters gives a rough baseline. Q1 averaged NT$378.0B a month and Q2 NT$423.5B. July and August average NT$491.2B, about 16% above the Q2 monthly pace, and August alone is 22% above it.
The guidance midpoint of US$45.2B implies about 12% growth over Q2's US$40.20B in dollar terms. So the first two months are running ahead of the midpoint pace in NT$, before September and before currency is netted out. That is a genuine positive signal about volume and pricing in aggregate. It is just not a signal about which node or which customer is responsible.
What it cannot tell you: nodes and AI
The monthly release gives a total and growth rates. There is no split by customer, product or node, no AI share and no profit. August's 10.1% sequential gain could reflect 2nm ramp, 3nm volume, pricing or simply shipment timing, and the release cannot separate them.
The same goes for customers. TSMC does not name them in monthly data, so linking a strong month to a particular accelerator launch is a guess dressed up as a reading. Supply chain reports can suggest it; the revenue release cannot confirm it.
Node mix only arrives with quarterly results. In Q2, 2nm was 3% of wafer revenue, 3nm 30%, 5nm 33% and 7nm 11%, with 77% at 7nm and below. The CFO pointed to a steep 2nm ramp in Q3. The first hard read on its pace comes with Q3 results in mid-October.
Margins were guided lower
Monthly revenue also says nothing about profitability. Q2 gross margin was 67.7%, while Q3 guidance is 65-67%, so even the top of the range sits below the last quarter. Revenue beating the high end would not by itself mean margins follow. I will leave the reasons to TSMC's own explanation rather than guess.
A simple routine for monthly prints
The useful habit is to convert each month straight into quarter-to-date progress against guidance, note the exchange rate, and stop there. Anything about mix, customers or margins waits for the quarterly release. That keeps a fast data point from becoming a narrative it cannot support.
What I actually watch
| Checkpoint | Why it matters |
|---|---|
| September revenue (around Oct 10) | Whether it lands in NT$444.8-483.2B (at 32) |
| Q3 results (mid-October) | 2nm share vs Q2's 3%, HPC share |
| Average Q3 exchange rate | Currency share of NT$ growth |
| Gross margin vs 65-67% guidance | Revenue and margin can diverge |
Value chain read-through
| Segment | Link | Signal |
|---|---|---|
| TSMC | Monthly revenue vs guidance | September print, node mix |
| AI accelerator designers | Leading-edge wafer demand | Quarterly HPC share |
| HBM suppliers | Moves with accelerator shipments | CoWoS capacity, supplier results |
| Equipment and materials | 2nm ramp spending | Capex execution |
Risks to this view
- The guidance conversion uses 32 NT$/US$; a different realized rate changes the coverage math.
- Monthly revenue is lumpy with shipment timing; one strong month is not a trend.
- August 2025 revenue and quarterly averages are derived from rounded figures.
- Reading 2nm or AI share into a monthly total has no disclosure behind it.
Next, I look at how far Nvidia and Palantir's supply chain AI actually automates decisions, using the benchmark Nvidia published.
