TSMC Q2 2026 — CoWoS/N3 Sold Out Through 2026

Core Thesis

TSMC's Q2 2026 print confirms AI compute demand is "still expanding, not flattening" — but the real signal for the datacenter buildout is on the supply side: CoWoS advanced-packaging capacity and the N3 (3nm) node are sold out through the end of 2026, with lead times stretching into 2027. Advanced packaging, not wafer starts, is the near-term ceiling on how fast hyperscalers can turn capex into installed GPU capacity.

Q2 2026 Results

• Revenue: NT$1.27T (~$39.62B), +36% YoY, above TSMC's own guidance band ($39.0–40.2B) — a record quarter.
• Full-year AI-segment revenue growth outlook raised to above 40%.
• CEO C.C. Wei: "Our conviction in the multi-year AI megatrend remains very high."
• Gross margin guided 65.5–67.5%; net profit and Q3 guidance were pending the full call at publication.

Supply-Side Signal (the datacenter-relevant part)

• CoWoS capacity: sold out through end-2026.
• N3 (3nm) node: sold out through end-2026, lead times into 2027.
• This directly gates GB200/GB300-class rack deployment — a hyperscaler with capex approved and power secured can still be capacity-constrained on the actual accelerator supply if it isn't already in TSMC's booked queue.
