ASML premarket up 2% as TSMC, Samsung commit to new EUV

The commitments from TSMC and Samsung are a demand signal that extends beyond ASML's order book. It suggests the leading-edge chip race is not slowing, which has ripple effects for the entire semiconductor supply chain and for capex-heavy foundries. The key question is whether this validates a broader upcycle in advanced equipment spending or merely concentrates it among a few players. Watch if these pledges translate into firm orders and whether other fabs follow, as that would confirm the durability of this demand.
