KLA is a structural near-monopoly in semiconductor process control, not a cyclical equipment vendor, with about 56% of process control and over 85% of optical wafer inspection. It combines pricing power, rising process-control content per wafer as chips grow more complex, and a recurring services base whose lifetime revenue per tool exceeds the tool's original price. Whichever AI application wins, chipmakers must pay the KLA toll as long as they demand smaller, faster chips. x.com x.com
