EUV monopoly

AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.

**Bottleneck theme:** Lithography & Fab Tools **Focus:** $ASML — ASML HOLDING NV ASML holds the EUV monopoly. There are zero alternatives below 7nm — every Rubin GPU, every HBM4 die, every leading-edge custom ASIC, and every advanced-node smartphone SoC passes through an ASML EUV tool. The duopoly position widens rather than narrows over time: the High-NA EUV (Twinscan EXE:5000) generation requires 10+ years and tens of billions of dollars of cumulative R&D that no alternative supplier can replicate. Customer concentration in TSMC, Samsung, Intel, and the leading memory makers gives ASML structural pricing power and order-book visibility unmatched in the industry. The investment case is multi-decade compounding through every leading-edge node transition (N2 → A16 → A14 → A10 ...) plus the long-term shift toward more-mask, more-EUV nodes. The bear case is short-term: China DUV revenue under export-control restrictions, lumpy EUV/High-NA revenue recognition, and an order book that can swing meaningfully quarter-to-quarter. Pair with $TSM (the customer), $LRCX/$AMAT/$KLAC (the complementary equipment), and indirectly with the entire AI hardware stack downstream.
