TSMC lifts 2026 spending plan as AI-chip demand outstrips capacity

TSMC has raised its 2026 capital-spending forecast to US$60–64 billion as demand for advanced chips continues to outstrip what it can supply. The company’s results also show its 2-nanometre process gaining ground, putting real numbers behind the AI-chip capacity race.

What happened

Startup Fortune reports that TSMC’s third-quarter revenue reached US$46.72 billion, up 50.9% year on year, and that net income rose 68.7% to about NT$763 billion. The company has raised its full-year revenue-growth forecast for the third time this year, to approximately 44% in US-dollar terms.

The report says TSMC’s 2nm chips made up 8% of wafer revenue in the quarter, up from 3% in the second quarter. It also reports the company’s latest capital-expenditure range of US$60–64 billion, up from US$52–56 billion. TSMC chief executive C.C. Wei told investors that demand for its most advanced chips remains strong enough for supply, rather than orders, to be the constraint.

Why it matters

TSMC manufactures chips used across the AI industry, so its capacity plans offer a grounded view of the infrastructure boom: not just what companies hope to buy, but what the world’s leading foundry says it can make. A higher spending forecast points to an effort to expand that supply, while the 2nm revenue share gives a concrete sign that the new process is entering the mix.

More capacity and record results do not settle whether all the spending on AI will pay off. They do show that, for now, TSMC says demand is running ahead of available supply. That has consequences for chip designers and the customers waiting on their hardware.

Our read

The strongest signal here is not another upbeat forecast. It is the combination of a raised investment plan and a reported capacity constraint, alongside 2nm moving from 3% to 8% of wafer revenue in a quarter. The bottleneck is physical, and loosening it will take more than a revised spreadsheet.

What to watch

• Whether TSMC’s expanded 2026 spending translates into more usable advanced-node and packaging capacity.
• Whether its next results show 2nm’s share continuing to grow.
• Whether the company maintains its revenue-growth outlook as supply expands.
• How the capacity constraint affects chipmakers and their customers.

Discussion spark: Should chipmakers and cloud providers treat TSMC’s capacity commitments as evidence that AI demand will endure, or as a costly bet that could leave them with excess supply?
