TSMC’s $46.7 billion quarter says AI chip demand still beats supply. Big Tech results from 21 October test the data center build

The world’s largest contract chipmaker has just told the market that the AI build-out is not slowing. TSMC’s third quarter beat its own guidance, its fourth-quarter outlook implies another step up, and its chairman said demand for AI chips still runs ahead of what the company can make. One day earlier, ASML, which supplies the lithography tools behind those chips, said its customers are already asking about orders for 2029 and 2030.

This is the market signal of the week for data centers. Chips ordered today become racks that need power, cooling and buildings in 2027 and 2028. The question for the next two weeks is whether the four largest buyers confirm that signal with their own spending plans.

What the signal says: TSMC’s quarter in numbers

TSMC’s third-quarter release, filed with the US Securities and Exchange Commission on 15 October, shows revenue of NT$1,494.24 billion, or US$46.72 billion. That is up 50.9% year on year in New Taiwan dollars and up 16.2% from the second quarter in US dollars. Net income rose 68.7% to NT$763.06 billion and the gross margin was 66.4%.

The mix matters more than the total. Advanced technologies at 7 nanometres and below made up 79% of wafer revenue. The 3 nm node alone was 33%, and the new 2 nm node, which only began its ramp this year, already reached 8%. High-performance computing, the platform that holds AI accelerators and data center processors, was 68% of revenue and grew 22% from the prior quarter, CRN Asia reported.

Chief Financial Officer Wendell Huang tied the quarter directly to leading-edge demand.

Where it points next: demand still ahead of supply

On the earnings call, Wei was asked whether AI demand is cooling. His answer was the opposite. He said TSMC’s earlier forecast for AI accelerator revenue to grow at a compound rate in the mid to high 50s percent from 2024 to 2029 would “probably” be exceeded, according to The Motley Fool’s transcript.

Huang added that TSMC expects capital spending from 2026 to 2028 to be “even more significantly higher than the past three years”, though he declined to give a 2027 figure. Wei also said volume production at TSMC’s next Arizona fab will begin in the third quarter of 2027, slightly ahead of schedule. Asked about where new capacity goes, he said the power supply situation is “one of the consideration factor” in TSMC’s planning.

In our view, that last remark is the bridge to the data center market. A chipmaker that is short of supply and planning more fabs is betting that its customers’ customers, the cloud and AI operators, will have buildings and grid connections ready for the output. Wei said TSMC plans capacity with “our customer’s customer” in mind.

Upstream confirms it: ASML and Samsung

TSMC was not alone this week. ASML reported record third-quarter net sales of €11.7 billion and net income of €5.0 billion on 14 October, with a gross margin of 57.5%. It guided fourth-quarter sales to €14.2 billion to €15.2 billion and full-year 2026 sales to €44 billion to €45 billion.

Fouquet said customers keep raising their equipment demand forecasts, “driven primarily by their views on the size and duration of AI-related investments”, and that ASML is studying ways to raise 2028 capacity beyond the 30% increase it had already announced.

Memory points the same way. Samsung Electronics guided on 8 October to third-quarter operating profit of about KRW 107.4 trillion on sales of about KRW 195 trillion. A year earlier, operating profit was KRW 12.17 trillion, so profit is up nearly ninefold (our calculation from Samsung’s figures).

Where the money lands: Big Tech’s 2026 spending plans

The chip signal only turns into data center demand if the buyers keep spending. Their last updates, given with second-quarter results in late July, pointed up.

• Amazon. Amazon raised its 2026 capital spending estimate to about US$220 billion from US$200 billion, citing higher memory costs, Fortune reported. CEO Andy Jassy said Amazon would not have enough capacity to meet all of its 2026 demand and expected the same in 2027. AWS revenue grew 37% to US$42.2 billion, its backlog stood at US$496 billion and AWS is on pace to double its power capacity by the end of 2027 compared with 2025.
• Alphabet. Alphabet raised its 2026 capex guidance to US$195 billion to US$205 billion from US$180 billion to US$190 billion. Of its roughly US$44.9 billion second-quarter capex, about 60% went to servers and 40% to data centers and networking equipment, W.Media reported. Google Cloud’s backlog reached US$514 billion.
• Meta. Meta narrowed its 2026 capex outlook to US$130 billion to US$145 billion, including principal payments on finance leases, from US$125 billion to US$145 billion. Second-quarter capex was US$31.08 billion, according to its results release.
• Microsoft. Microsoft’s calendar 2026 capex is now about US$175 billion, down from an earlier estimate of US$190 billion, because of an accounting change that moves future data center leases from finance to operating leases, CFO Dive reported. The company said its AI infrastructure plans were unchanged.

Microsoft Chief Financial Officer Amy Hood explained why the headline number fell even though the build plan did not.

Sources: Fortune, 30 Jul 2026; W.Media, 23 Jul 2026; CFO Dive, 30 Jul 2026; Meta, 29 Jul 2026; results dates from Amazon, Alphabet and Meta investor notices; Microsoft’s date from its 7 October investor notice. Our total uses US$220 billion, US$200 billion, US$175 billion and US$137.5 billion. Company definitions differ (Meta includes finance lease principal; Microsoft’s figure excludes operating leases), so the total is indicative only.

What it means for the data center build

Chip revenue is the earliest hard number in the AI supply chain. Wafers TSMC ships in the fourth quarter become accelerators and servers in 2027, and those servers need powered halls. Alphabet’s split gives a rough sense of scale: if about 40% of its 2026 capex midpoint of US$200 billion goes to data centers and networking, as in its second quarter, that is about US$80 billion in one year from one company (our calculation, assuming the second-quarter split holds for the year).

The constraint is moving from chips to sites. Jassy’s warning that AWS cannot meet all of its demand in 2026, and its plan to double power capacity by the end of 2027, describe a market where powered capacity, not silicon, sets the pace. That is consistent with the grid and permitting limits we covered in our Texas queue analysis and our PJM analysis.

In our view, this is the core of the signal. Upstream suppliers are now planning for 2028 and beyond. Data center developers that can deliver power on a 2027 and 2028 timeline are in the strongest position they have been in, and those that cannot will watch demand move to other markets.

What could weaken the signal

Margins. TSMC’s gross margin slipped 1.3 points from the second quarter to 66.4%, CRN Asia reported, and fourth-quarter guidance of 65% to 67% does not rise. The 2 nm ramp is expensive.

Accounting, not appetite. Microsoft’s lower capex number shows that headline capex can fall while the build continues through leases. Investors comparing quarters need to read lease disclosures as well as capex lines.

Supply caps. If ASML cannot ship enough tools for 2027 and 2028, chip output and the server pipeline behind it are capped. That would slow, not end, the data center demand the chips imply.

Memory costs. Amazon said higher memory prices pushed its capex estimate up by US$20 billion. Part of the growth in spending is price, not volume.

What to watch next

• 21 October 2026: Meta reports third-quarter results after the US market close, with any update to its US$130 billion to US$145 billion 2026 capex range.
• 28 October 2026: Alphabet and Microsoft report. Alphabet’s capex range and cloud backlog, and Microsoft’s lease disclosures, are the key lines.
• 29 October 2026: Amazon reports, including AWS growth, backlog and its US$220 billion 2026 capex estimate.
• January 2027: TSMC fourth-quarter results (date not yet set) and the first 2027 capex figure, which Huang declined to give this week.
• Third quarter 2027: volume production at TSMC’s next Arizona fab, slightly ahead of the previous schedule, Wei said.

Frequently asked questions

How much revenue did TSMC report for the third quarter of 2026?

US$46.72 billion, or NT$1,494.24 billion, up 41.2% year on year in US dollars. Net income rose 68.7% to NT$763.06 billion and the gross margin was 66.4%.

What did TSMC say about AI demand?

Chairman C.C. Wei said demand is still higher than supply and that TSMC’s forecast of mid to high 50s percent compound growth in AI accelerator revenue from 2024 to 2029 will probably be exceeded. TSMC guided fourth-quarter revenue to US$52.3 billion to US$54.3 billion.

Why does a chipmaker’s result matter for data centers?

About 68% of TSMC’s revenue now comes from high-performance computing, which includes AI accelerators. Chips shipped now become servers that need powered data center capacity in 2027 and 2028.
