TSMC posts another record quarter on AI demand, but plans carefully for 2027

Every time you ask an AI assistant a question, a data centre somewhere does the work, and the chips inside it may well have come from one company in Taiwan. That company, TSMC, has just reported another record quarter. Yet its boss also struck a careful note about next year.

TSMC Q3 earnings matter far beyond Taiwan. TSMC (Taiwan Semiconductor Manufacturing Co) builds chips that other firms design, and Reuters names Nvidia and Apple among its key customers. Its results are one of the clearest readings of whether the AI boom is still real. On this evidence, it is. But the outlook for 2027 is more mixed.

TSMC Q3 earnings: AI chips carried revenue to US$46.72 billion

TSMC’s own figures for July to September 2026:

• Revenue: NT$1,494.24 billion (New Taiwan dollars), or US$46.72 billion. That is 41.2% more than a year ago in US dollars, and above TSMC’s own forecast of US$44.6–45.8 billion.
• Net income: NT$763.06 billion, up 68.7% on a year ago. Reuters and CNBC report this is TSMC’s sixth quarter in a row of record profit. Reuters puts it at about US$23.59 billion.
• Margins: TSMC kept 51.1 cents of profit from every dollar of sales. Gross margin dipped to 66.4% from 67.7% in Q2, mainly because its newest 2-nanometre (2nm) chips are still early in production.

The mix tells the bigger story. High-performance computing, meaning AI and data-centre chips, made up 68% of revenue, up from 57% a year ago. Smartphones fell from 30% to 21%. Customers in North America brought in 79% of revenue.

TSMC expects more. Its Q4 guidance is US$52.3–54.3 billion in revenue. Reuters reports TSMC now sees full-year 2026 revenue growing about 44%.

Why a record quarter came with a careful word on 2027

On the TSMC earnings call, CEO C.C. Wei spoke about the year ahead. As reported by Reuters, he said: “consumer and price-sensitive end-markets segments are being challenged due to the impact of rising component prices and macroeconomic uncertainties. As such, we are being prudent in our business planning going into 2027.” There is no formal TSMC 2027 forecast yet, only a promise of prudence.

So, by TSMC’s own account, the caution is not about AI. Reuters reports TSMC called AI demand “extremely robust”. Sravan Kundojjala, an analyst at research firm SemiAnalysis, told CNBC that TSMC checks whether customers can really deploy AI systems, and “even after those checks, TSMC says demand remains well above its supply capacity.”

The open question is whether AI can keep growing fast enough to carry TSMC while phones and PCs slow down. Gary Tan, a portfolio manager at Allspring Global Investments (which owns TSMC shares), told Reuters the risk is that this caution spreads into wider earnings cuts across the chip supply chain, though for now it “looks like sensible expectation management”.

TSMC says its second Arizona factory should start mass production in Q3 2027, slightly ahead of plan, Reuters and CNBC report. Rumour: TSMC could build a factory in Texas. Reuters reported in September, citing two unnamed sources, that TSMC was evaluating an investment there; TSMC declined to comment at the time. On the call, Wei confirmed only that teams were sent to evaluate it. No decision, site or amount has been announced.

What the AI shift means for your next phone and your savings

For most people, the key line in these TSMC Q3 results is Wei’s mention of “rising component prices”. In our reading, that suggests phones and laptops could cost more, or sell fewer, in 2027. That is an inference, not a TSMC forecast. If a new phone or laptop is on your 2027 list, watch launch prices closely.

If you own TSMC shares or a fund that holds them, watch the outlook, not the record. Reuters reports TSMC shares in Taipei fell 2% before the release, during a wider tech sell-off, even though they are up 57% this year. Strong results do not always mean a rising share price.

Strong demand, honest limits: why this caution is a healthy sign

On balance, these results are good news for the AI build-out. Revenue, profit and the Q4 outlook all point up, and the newest 2nm chips are already 8% of wafer sales.

The less comfortable part is the gap that is opening. AI data centres are thriving, while the devices most people actually buy face higher costs. A company this dependent on one boom carries real risk if that boom cools.

Still, the likelier reading is the calm one. Saying “prudent” while demand exceeds supply is what a steady company does. It suggests TSMC is planning for a normal cycle, not bracing for a fall.

The next test comes when TSMC reports its fourth quarter. Watch whether phone and PC sales hold up, and whether “prudent” turns into lower numbers.
