Chip Giants: Who's the Safer Bet?
23 Oct
Summary
- ASML holds a unique monopoly on EUV lithography machines.
- TSMC dominates chip fabrication with 72.5% market share.
- TSMC is considered a safer investment despite ASML's monopoly.

Taiwan Semiconductor Manufacturing (TSMC) and ASML Holding are industry titans, each with a unique near-monopoly. ASML's technological advantage is its sole production of crucial extreme ultraviolet (EUV) lithography machines, essential for creating advanced chips.
TSMC's dominance stems from its massive scale in chip fabrication, capturing 72.5% of industry revenue in Q2. This significant market share effectively locks in clients due to competitors' inability to match TSMC's capacity.
However, ASML's business model hinges on expanding chip production, a demand that may wane after the current AI build-out. TSMC, conversely, could benefit from future technological advancements like autonomous vehicles and robotics, suggesting a more stable business outlook.
Valuation analysis indicates ASML trades at a premium compared to TSMC, based on future earnings estimates for 2026 and 2027. Consequently, TSMC is positioned as the more secure investment choice.
