ASML and TSMC Forecasts Confirm AI Capex Cycle

ASML and TSMC both issued strong forward guidance, signaling that capital expenditure cycles tied to AI infrastructure remain on track despite broader macro uncertainty. The two companies sit at opposite ends of the semiconductor supply chain, ASML manufactures the extreme ultraviolet lithography machines that enable advanced chip fabrication, while TSMC is the world's dominant contract chipmaker, making their aligned outlooks a reliable cross-check on demand health across the sector. Their forecasts suggest hyperscaler and AI accelerator spending commitments are translating into real equipment orders and wafer capacity bookings, not just announced intentions. Investors and analysts tracking the AI capex cycle will treat these data points as confirmation that near-term demand is holding, though the durability of the cycle beyond current order books and any concentration risk among a small number of large AI customers remain the key variables to monitor going forward.
