TSMC CEO: AI chip demand will exceed leading-node capacity by 25–30% in 2026 — no relief until 2027
TSMC CEO C.C. Wei told shareholders on June 4 that demand at leading nodes will outpace capacity by 25–30% in 2026, with CoWoS advanced packaging — which stacks HBM memory on Nvidia and custom-silicon accelerators — sold out and the constraint not lifting until at least 2027. With Alphabet committing $84.75B in new AI data-center equity and other hyperscalers accelerating their 2026–2027 capex, the TSMC bottleneck is now a hard ceiling on how fast AI infrastructure can scale — demand is there, the silicon isn't.

Customer demand is so high, and we can only support so much.

Why this matters
- → AI infrastructure scaling hits hard physical ceiling through 2027.
- → Hyperscaler capex stalled by chip supply, not demand or funding.
- → Leading-node shortage forces customers to compete for allocation.
