Every new fab is built from tools made by a handful of segment monopolists, and the AI cycle (leading-edge logic + DRAM/HBM + advanced packaging) is driving a higher-intensity WFE wave with long lead times that gates how fast capacity can come online.

+4 this quarter — Record WFE spending (~$145B in 2026) and an intensity cycle expected to persist through the back half of the decade, served by segment oligopolies (litho, deposition/etch, metrology, test) with extended lead times — tight but with multiple vendors per category, so not as acute as the EUV monopoly.
WFE is the machinery that builds every chip fab — deposition, etch, lithography, metrology and test. A higher 'WFE intensity' cycle means each incremental wafer of leading-edge, memory or advanced-packaging capacity needs more (and more expensive) tools, and each tool category is dominated by one or two suppliers with long delivery times. That makes equipment availability, not just fab construction, a real pacing item for capacity additions.

What would loosen it
Capacity digestion after the current build-out, a pullback in China equipment buying, or slower-than-planned foundry and memory capex.

Analysts: advanced-packaging capacity could expand ~80% YoY in 2026; higher WFE-intensity cycle expected to persist through the second half of the decade.
