Question
AI Infrastructure Capex Expands Into Power, Liquid Cooling, and Optical Interconnects
Direct answer
Hyperscale computing clusters are encountering power and heat dissipation limits, shifting procurement urgency to physical layer infrastructure. Modine is capturing liquid cooling deployments, while Astera Labs and Applied Optoelectronics supply interconnects required to link distributed clusters.
Despite robust secular demand, infrastructure suppliers including Vertiv and Applied Optoelectronics have pulled back from 2026 valuation highs, reflecting market digestion of lead times and near-term margin pass-through capabilities.
