TSMC Q3 Earnings: Record Profit Up 68.7% as AI Demand Lifts 2026 Outlook

The world's largest contract chipmaker made what is now a familiar move: it beat estimates, set another record, and raised its outlook. Taiwan Semiconductor Manufacturing delivered a third-quarter net profit of NT$763.1 billion, up 68.7% from a year earlier and the sixth straight quarterly record, powered by an unrelenting appetite for AI processors.

The number that matters most sits in the guidance, not the print. TSMC now expects full-year 2026 revenue to grow about 44% in U.S. dollar terms, up from the roughly 40% it promised in July. Management also guided fourth-quarter revenue of $52.3 to $54.3 billion, a sequential gain of around 14% and a year-over-year jump of about 58%, according to TrendForce and the company's own earnings release.

Revenue for the quarter reached NT$1.494 trillion, or $46.36 billion, up 50% from the prior year and ahead of the NT$1.47 trillion LSEG SmartEstimate. Net income of NT$763.1 billion beat the NT$746.34 billion analysts had penciled in, and operating margin came in at 58.7%, above the upper end of the company's own 58% guidance. Free cash flow surged to NT$476.56 billion from NT$139.38 billion a year earlier, CNBC reported citing the release.

What is driving the beat is easy to isolate in the platform data. High-performance computing, the category that houses AI accelerators and their supporting silicon, made up 68% of revenue and grew 22% quarter over quarter. Smartphones contributed 21%, and automotive was the fastest-growing platform on a sequential basis at 23%. By node, 3-nanometer chips led at 33% of wafer revenue, followed by 5-nanometer at 28% and 7-nanometer at 10%.

The 2-nanometer story is the one to watch for margin math. TSMC said the 2nm node's share of wafer revenue climbed to 8% from just 3% in the second quarter, evidence that the ramp is picking up real volume. That ramp is also the reason management's fourth-quarter gross margin guidance of 65% to 67% sits below the third quarter's outcome, with operating margin of 56.5% to 56.8%. Rapidly scaling a new node costs money before the yield and utilization curves flatter out, and the market is being told that pressure is here now.

The capex line reinforces the longer view. TSMC reiterated 2026 capital spending guidance of $60 billion to $64 billion and said it plans to spend more over the 2026 to 2028 period than it did in the preceding three years, a client note that underscores how far out the AI build-out is being booked.

For AI markets, this print is the cleanest confirmation yet that the equipment-cycle signals firing across the sector are landing in actual revenue. ASML said last week that planned lithography supply for 2027 and 2028 will not cover customer demand, and TSMC's numbers show why: the foundry is the gating customer converting that tool demand into wafers, and it is running ahead of plan.

There are real counterweights. The fourth-quarter margin guide shows the 2nm ramp carries a cost, and the ADR reaction has been muted after a week in which hotter-than-expected U.S. inflation re-armed the case for further Fed tightening, a headwind for long-duration growth and AI infrastructure names alike. The ADR closed at $430.00 on October 14, down 3.4%, according to Investing.com exchange data, ahead of this print. Memory suppliers Samsung, SK Hynix and Micron also slid this week after China's ChangXin Memory Technologies unveiled rival technology, a reminder that the AI demand story is concentrated in a few names.

Wider currency and power dynamics matter for how far these numbers travel. The new Taiwan dollar's path against the U.S. dollar distorts U.S.-reported revenue, and analysts will parse how much of the 50% top-line growth is volume against how much is favorable exchange. On the supply side, power-constrained data center buildouts in the United States are an input cost and a scheduling risk for the accelerator order book that feeds HPC revenue, even as the demand pipeline itself shows no sign of cooling.

The next numbered catalysts are already on the calendar. NVIDIA's own results this cycle will tell investors how much of TSMC's HPC growth is accelerator revenue rather than jitter from a single order book, and the first TSMC monthly revenue report for October is the closest forward check on the fourth-quarter guide. On the company's own numbers, the bull case is that demand visibility extends years out; the bear case is that the margin cost of getting 2nm to scale shows up in the quarters immediately ahead.
