Design an AI chip and you still have to build it — and the number of places that can build a leading-edge chip is astonishingly small. In practice, the cutting edge runs through a handful of fabs, most of them TSMC’s, using lithography machines only ASML makes.
Foundry capacity is the real starting line
Foundry capacity — the ability to actually manufacture the most advanced chips — is the first physical gate every AI accelerator passes through. It takes years and tens of billions to add, which is why a surge in AI demand can’t simply be met by building more fabs this quarter.
A chokepoint on top of a chokepoint
Above the fab sits an even narrower point: the extreme-ultraviolet lithography tools that make leading-edge nodes possible come from a single supplier. When one company gates the tools and one company dominates leading-edge capacity, the whole industry inherits their pace.
Seeing the exposure
That concentration is why foundry and lithography names sit so deep in the chain’s dependency graph. THE ENTITY places each where it actually sits and shows who leans on it — so the chokepoint is legible, not folklore. Research, not advice.
