Taiwan Semiconductor Manufacturing Co (TSMC) posted a record third-quarter profit on Thursday, October 15, 2026, as surging demand for artificial intelligence chips pushed both revenue and earnings to new all-time highs. Net profit jumped 68.7% from a year earlier to NT$763.1 billion (about $23.6 billion), beating analyst estimates and extending the world's largest contract chipmaker's streak of record quarters to six.
The results, reported from TSMC's headquarters in Hsinchu, Taiwan, underscore one uncomfortable truth about the AI boom: demand for the chips that power it keeps outrunning supply — and the company that makes most of them keeps cashing in. Here is a full breakdown of the numbers, what drove them, and what they signal for the rest of the AI trade.
TSMC Q3 2026: The Numbers
- Net profit: NT$763.1 billion (~$23.6 billion), up 68.7% year-on-year — a record, and above the NT$746.3 billion LSEG SmartEstimate consensus.
- Revenue: NT$1.494 trillion (~$46.7 billion), up 50.9% year-on-year and 17.6% quarter-on-quarter — above the top end of TSMC's own $44.6–45.8 billion guidance.
- Earnings per share: NT$29.43, up 68.7% from NT$17.44 a year ago.
- Gross margin: 66.4% (down slightly from 67.7% in Q2 as the new 2nm process ramps up); operating margin hit 58.7% — above the top of company guidance.
- Record streak: sixth consecutive quarter of record net profit.
Where the Growth Came From
The engine of the quarter was high-performance computing — the category that includes AI server and data-centre chips. HPC now accounts for 68% of TSMC's revenue, up from 57% a year earlier, while smartphones make up 21%. HPC revenue grew 22% from the previous quarter, far outpacing the smartphone segment's 10%.
The mix of chips tells the same story. TSMC's most advanced processes dominated: 3-nanometre chips were 33% of wafer revenue, 5nm was 28%, 7nm was 10% — and the brand-new 2nm process, which only started volume production this year, leapt from 3% of revenue last quarter to 8%. Combined, processes of 7nm and below made up 79% of all wafer revenue.

Major customers including Nvidia and Apple are soaking up that leading-edge capacity. TSMC said demand for its leading-edge technology remains stronger than available supply — and it is not the only gatekeeper saying so: just a day earlier, ASML, the Dutch maker of the lithography machines every advanced chip needs, said its planned 2027/2028 supply will not meet demand. From the profit side, TSMC is now confirming the same message: in the AI buildout, demand is not the problem — supply is.
The Margin Question: Why Profitability Is Being Watched
If there was a test in this quarter's report, it was margins rather than demand. Gross margin slipped 1.3 percentage points from Q2 to 66.4%, which TSMC attributed mainly to margin dilution from the initial ramp of 2nm production. Building cutting-edge fabs outside Taiwan — which costs far more than production at home — adds further pressure.
Still, the company is spending through it. TSMC reiterated 2026 capital expenditure of $60–64 billion, guided fourth-quarter revenue to $52.3–54.3 billion (about 14% sequential growth at the midpoint), and projects full-year 2026 revenue growth of 44% in US-dollar terms — a forecast it has now raised twice this year.
Why the US Cares: Arizona, Texas and a $2 Trillion Valuation
For American readers, the story has a domestic address. TSMC is in the middle of a $265 billion buildout in Arizona, its biggest overseas manufacturing commitment, and is reportedly evaluating a further expansion in Texas — including reported discussions around Elon Musk's Terafab project. The company's market capitalisation now sits near $2 trillion, roughly double that of South Korean rival Samsung Electronics.

That scale is why TSMC's earnings day doubles as a health check for the entire AI trade — from Nvidia's accelerators to the cloud giants racing to buy them.
A Record on a Rough Day for Tech Stocks
Notably, the record beat landed on a brutal day for technology shares. Hotter-than-expected US inflation data — September CPI at 3.7% and producer prices up 6.3% annually — revived bets on another Federal Reserve rate hike, and chip stocks sold off for a sixth straight session. The contrast is the story in miniature: TSMC's fundamentals have rarely looked stronger, but the market is pricing in what expensive money could do to the AI spending spree.
TSMC Q3 2026: FAQs
What does TSMC do?
TSMC (Taiwan Semiconductor Manufacturing Company) is the world's largest contract chipmaker — a "pure-play foundry." It doesn't design chips; it manufactures them for clients like Nvidia, Apple and AMD that do. It makes roughly 90% of the world's most advanced chips.
Why did TSMC's profit jump 69%?
Relentless demand for AI chips. High-performance computing now drives 68% of revenue, and TSMC's advanced 3nm and 2nm processes are running at full tilt with pricing power — AI customers are paying premium prices because supply is tight.
What are 2nm and 3nm chips?
The numbers refer to transistor sizes — smaller means more transistors per chip, and therefore more computing power with less energy use. TSMC's 2nm process, now in volume production, is the most advanced chip technology in mass production anywhere.
What is TSMC's outlook for Q4 2026?
The company guided fourth-quarter revenue to $52.3–54.3 billion with gross margin of 65–67%, and expects full-year 2026 revenue to grow about 44% in US-dollar terms. Management says leading-edge demand still exceeds supply.
Why does TSMC matter to the US economy?
TSMC's chips power everything from iPhones to Nvidia's AI data centres. Its $265 billion Arizona expansion and possible Texas investment are central to America's push to make advanced chips at home rather than relying on Taiwan.
