Leading-edge foundry concentrates further as TSMC ramps N2 and capex

In one sentence. TSMC began recognising N2 revenue in Q2 2026 with mass production ramping in the second half, raised 2026 revenue growth guidance from above 30% to above 40%, and lifted capex to $60-64bn.

Why it matters

There is effectively one supplier of volume leading-edge logic, and it is raising prices and capex simultaneously while keeping 67.7% gross margins. Every AI, mobile and networking roadmap in the world is a derivative of one company's allocation decisions, concentrated on one island.

What is happening

TSMC began recognising N2 revenue in Q2 2026 with mass production ramping in the second half, raised 2026 revenue growth guidance from above 30% to above 40%, and lifted capex to $60-64bn. HPC reached 66% of Q2 revenue, a record for the second consecutive quarter. Top-10 foundry revenue was $53.49bn in Q2 2026 per TrendForce, up 11.5% sequentially. Samsung Foundry improved on HBM base-die and 2nm HPC wins but remains a distant second; Intel's 14A is explicitly contingent on external customers.

First observable signal. TSMC's 3nm monopoly in 2023-24; the decisive signal was Intel and Samsung failing to convert 2024-25 node announcements into external volume.

Evidence

Claim Type Date Source
TSMC Q2 2026 revenue $40.20bn, gross margin 67.7%, operating margin 60.3%, EPS NT$27.25; Q3 guidance $44.6-45.8bn fact 2026-07-16 TSMC Investor Relations (A)
HPC was 66% of TSMC Q2 2026 revenue, +20% QoQ, a record for the second consecutive quarter; N2 began contributing revenue fact 2026-07-16 MacroMicro (Taiwan) (B)
Top-10 foundry revenue nearly US$53.49bn in 2Q26, +11.5% QoQ, with SMIC narrowing the market share gap with Samsung fact 2026-09-09 TrendForce (Taiwan) (B)
Samsung Foundry earnings improved on HBM base-die and 2nm HPC orders, targeting double-digit H2 revenue growth fact 2026-07-30 Samsung Global Newsroom (Korea) (A)
Intel 18A reached high-volume manufacturing but yields remain below profitable levels; 14A depends on two prospective customers deciding H2 2026 to H1 2027, and may be slowed or cancelled… fact 2026-03-16 Tom's Hardware (Luke James) (B)

Where sources disagree

  • TSMC 2026 capex — TSMC IR quarterly results page (Q2 2026): Capex guidance not stated on the summary results page; only revenue and margin guidance published vs Earnings-call reporting (MacroMicro, Bits&Chips): US$60-64bn, raised from US$52-56bn. Likely reason: TSMC gives capex guidance verbally on the earnings call rather than in the results summary page. The figure is well-corroborated across independent outlets but the primary artefact is the call transcript, not the results page.

Companies and products

Companies. TSMC, Samsung Electronics, Intel, SMIC, UMC, GlobalFoundries, Rapidus
Products. N2, N3, A16, SF2, Intel 18A, Intel 14A
Funding. TSMC 2026 capex $60-64bn; Arizona commitment raised by $100bn to $265bn total. Rapidus is funded by Japanese government subsidy plus corporate equity.

Impact

Industry. Beneficiaries: TSMC, ASML, semicap suppliers, Taiwan's economy. Losers: Intel Foundry, Fabless firms facing price increases, Anyone needing capacity without a long-term relationship.
Consumer. N2 tape-outs span Apple, NVIDIA, AMD, Qualcomm, MediaTek and hyperscaler custom silicon. Samsung's 2nm HPC wins are real but unnamed in its own disclosure.
Regulatory. Very high. CHIPS Act and equivalents in Japan, Korea, EU and Taiwan subsidise capacity; Section 232 Phase 2 threatens tariffs on additional semiconductors and manufacturing equipment.
Geography. TW, US, KR, JP, CN, EU

Risks and counter-forces

  • Taiwan Strait geopolitical shock
  • Capex committed at cycle peak
  • Overhang if AI demand normalises while N2 capacity lands

Counter-trends. Government-subsidised second sources (Rapidus, Intel Foundry, SMIC); customer pressure for dual-sourcing after 2021-22 shortages

What to watch next

  • T-03-02 Advanced packaging, not wafers, is the binding constraint on AI compute
  • T-03-06 Semicap equipment spending is outrunning the industry's own forecasts
  • T-03-10 China's real bottleneck is HBM and materials, not logic - and it is being attacked directly
  • T-03-20 Intel Foundry's external-customer turnaround treated as a settled outcome
