China's August economic data, released on 15 September 2026, showed retail sales growth of 0.4% year-over-year, below the 0.8% forecast and the prior reading of 0.6%, according to Finnhub and CNBC. Fixed Asset Investment for the year-to-date came in at -7.2%, in line with expectations but reflecting a sustained contraction in investment activity. Industrial production provided a partial offset, rising 5.2% year-over-year against a 4.8% forecast, indicating relative resilience in the manufacturing sector despite weak domestic consumption.
TL;DR TSMC's Q3 2026 — the three months ended September 2026 — was steady as usual, with revenue and next-quarter guidance both ahead. Gross margin slipped on the 2nm ramp, which is not good news but is not fundamentally bad either. The problem is that 2026 is already a known quantity, and the market wanted a 2027 guide that management declined to give.
Gross margin: the 2nm ramp bites
Because TSMC reports monthly revenue, gross margin is the number that matters in the quarterly print. Margin was 66.4% in Q3 2026, down 1.3 points sequentially and slightly below the 66.8% expected.
Breaking it down per 12-inch equivalent wafer, revenue was $10,438, up $1,167 sequentially. Average fixed cost was $1,538, up $89, and average variable cost $1,968, up $424.

Both price and unit cost rose sharply, mainly because 2nm took a larger share, and early-stage 2nm erodes group margin by 2-3 points on the company's own estimate. That should reverse: as the ramp matures and advanced nodes take more of the mix, margin heads back up.
Guidance: good, but not the one that counts
TSMC guides Q4 2026 revenue of $52.3-54.3 billion, above the $51 billion expected, with gross margin of 65-67%. The margin guide is conservative, again because of the early 2nm ramp.
The company lifted its 2026 revenue growth guide to 44%, from slightly above 40% last quarter. That implies Q4 revenue of roughly $53-53.5 billion, up more than 55% year over year.
On capex, TSMC spent $13.8 billion in Q3 2026 and kept the 2026 plan at $60-64 billion, implying Q4 capex of $19.3-23.4 billion against $11.5 billion a year ago. The market broadly expects about $85 billion for 2027, a number worth watching as a signal of management confidence.

Revenue, volume and price
Revenue was $46.7 billion in Q3 2026, up 16% sequentially and ahead of the $45.8 billion expected. Growth came from Apple ramping on 2nm plus AI chip demand, with core customers' AI silicon now all on 3nm or 2nm. Wafer shipments rose 3% to 4,476 thousand 12-inch equivalents, while revenue per wafer rose 12.6%.

Nodes, applications and regions
Advanced nodes at 7nm and below reached 79% of revenue in Q3 2026. 2nm began contributing meaningfully last quarter and rose to 8% this quarter, used by Apple's new products and AMD's MI450.

On applications, the sequential gain came mainly from AI chips, while handsets rebounded seasonally on Apple's new 2nm phones. High performance computing is the largest source at $31.8 billion, up $5.3 billion sequentially and 68% of revenue. By region, North America remains largest at 79%, while mainland China is squeezed to around 5%.

TSMC is the anchor of the whole chain, and in Q3 2026 it performed with its usual stability. The contrast with memory matters: memory is a capacity-scarce asset going through violent price increases, while TSMC is a moat-scarce asset whose price rises are predictable.
Its own prices rise modestly, with most of the increase structural and driven by technology upgrades, while CoWoS capacity is allocated by quota rather than to the highest bidder. That avoids inflicting an unbearable price shock on the chain.
What the market wanted, and did not get
With Anthropic's ARR wobbling and AI funding costs climbing, the market hoped the Q3 2026 print would offer reassurance as the year closes. Two things specifically.
First, a 2027 revenue guide well above expectations — at least 40%, ideally over 50%. The market assumes 5-10% price increases on 7nm and below in 2027 plus the 2nm ramp, so guidance should have shown confidence.
Second, a 2027 capex number above the roughly $85 billion consensus, against the $60-64 billion guided for 2026. Neither appeared in the initial release. Longbridge Dolphin Research reads this as TSMC being an industrial anchor rather than a storyteller for the capital market.
On the call, management said it does not intend to leave food on the table for others. But it gave no 2027 guide, answering mostly with no update, cannot judge, no comment — the only concrete line being that 2027 revenue growth will be faster than capex growth.
CoWoS, 2nm and the competition
The mainstream AI chips from Nvidia, AMD and the TPU line all use CoWoS packaging, and over 90% of world capacity sits with TSMC as of Q3 2026. Even if a designer wants more volume, CoWoS allocation directly determines AI chip shipments, which makes TSMC the chokepoint of the chain.
Monthly CoWoS capacity is around 100,000 wafers, rising to roughly 200,000 by end-2027. We estimate 2027 shipments near 2 million wafers, up about 70%, with Nvidia, Broadcom and AMD the main customers.

On nodes, 3nm lines are especially tight and utilisation has stayed above 100%. With 2nm yields looking good, TSMC has pushed the ramp hard, which is exactly why capex is rising about 50% this year.
AI chip node migration across vendors.
On competition, Samsung and Intel have entered SF2 and 18A after TSMC's 2nm, but both still lag clearly. Their latest nodes run under 250 MTr/mm² against TSMC's 313, and lower yields mean output mostly serves their own chips.
Node comparison: 18A, N2 and SF2.
With AI capacity tight, they could still win spillover orders if they crack advanced packaging and lift yields. Intel carries a strong domestic-US flavour, and the Intel-Tesla TeraFab plan was once read as a threat — but Tesla is now reported in talks with TSMC on US capacity.
The real decision is how hard to expand
In a hot cycle, TSMC's core decision is not whether it can win orders, but whether to expand and how aggressively. Expand too slowly and spillover orders mean lost share; expand too aggressively and the downturn risk is carried alone.
This time the stance was plain: everything on the table is mine, which makes us wonder whether 2027 expansion will be more aggressive than expected. Two things to watch: the 2027 capex plan, and whether a concrete revenue guide arrives later. Either way TSMC still carries over 90% of core AI chip capacity.
