Taiwan Semiconductor Manufacturing posted its sixth consecutive record quarter on Thursday, with third-quarter net profit of NT$763.06 billion — roughly $23.6 billion — a 68.7% jump from the year-ago quarter. Revenue reached NT$1.494 trillion — $46.72 billion — up 50.9% in local currency and 41.2% in dollar terms. Both figures beat expectations: profit topped the LSEG consensus of NT$746.3 billion by roughly 2.2%, while revenue finished above TSMC's $44.6–45.8 billion guidance range. Per-share profit came in at NT$29.43 — $4.60 per ADR — up 68.7% from a year earlier.
The mix is where the AI story lives: high-performance computing — AI accelerators and processors for data centres — supplied 68% of revenue, up from 57% a year earlier, while smartphones managed just 21%.
On the earnings call, chief executive C.C. Wei said demand for leading-edge technology remained exceptionally strong and lifted the 2026 revenue growth forecast to roughly 44% in dollar terms. For the fourth quarter, TSMC guided revenue of $52.3–54.3 billion — roughly 14% quarter-on-quarter at the middle of the guided range, and 55% to 61% above last year's fourth quarter. CNBC reported that customers including Nvidia, Apple, Broadcom and AMD are competing for TSMC's chip capacity, and the order data backs the scarcity narrative: the newest 2-nanometer node has already reached an 8% share of wafer revenue, up from just 3% a quarter earlier, with 3nm contributing 33%, 5nm 28% and 7nm 10%.
Profitability stayed exceptional even as the 2nm ramp diluted it. Gross margin came in at 66.4% — down 130 basis points from the second quarter, but up 6.9 points from a year ago. Operating margin of 58.7% beat the top of TSMC's guided 56–58% range. Management said overseas fabs are costing about two points of gross margin today, a drag that could reach three or four points as the Arizona and Japan plants ramp.

Why it matters
This quarter was a direct answer to the market's biggest question: has AI spending peaked? Wednesday's rout priced in hot US inflation — September CPI printed 3.7% year on year — and revived fears that higher rates would choke the capex funding the AI buildout, as we covered in the Asia chip rout and the Nasdaq slide. TSMC's response: raise the growth outlook, lift capex, and guide a fourth quarter that — at the $53.3 billion midpoint — would top the record it just set.
The signal for chip investors is simple: wafer supply, not end demand, is now the binding constraint.
The read-through cuts both ways. The physical AI buildout is still accelerating: TSMC lifted its 2026 capital budget to $60–64 billion, already raised once this year from $52–56 billion, and says 2026–2028 spending will run significantly higher than the previous three years. But the boom is getting more expensive to serve — the 2nm ramp and overseas fabs are already costing points of margin, and Wei himself cautioned that big margin gains "will not arrive overnight."
What to watch
- October monthly sales (early November): the first check on whether the Q4 ramp toward $52.3–54.3B is real.
- 2nm yields and margins: Q4 gross margin guidance is 65–67% — any slip means the ramp is costing more than planned.
- Fed meeting, October 27–28: hot CPI has an October hike back on the table at roughly 49% odds; another hike would re-rate every AI-linked multiple.
- Arizona fab progress: overseas fabs already cost about 2 points of gross margin, heading for 3–4 points as Arizona and Japan scale.
- AI accelerator outlook: Wei kept the mid-to-high-50s CAGR target for AI accelerator revenue through 2029 but said it would "probably end up higher" — a formal upgrade would be a fresh catalyst.
MarketRadar take
The arithmetic of the AI boom keeps improving for TSMC and getting harder for everyone else. Our math: high-performance computing revenue works out to roughly $31.8 billion for the quarter, up about 68% from a year earlier — meaning nearly all of TSMC's dollar growth is now AI-driven. The tension is valuation, not fundamentals: Taipei shares still closed 2% lower on Thursday and the ADR slid 3.4% to $430 on Wednesday, because a stock priced for perfection met a Fed pricing hikes. Until the October 28 decision, even record quarters may keep getting sold.
