Crown Castle CCI

Real EstateMarket cap $48B5 connections

Crown Castle owns 40,000+ cell towers, 115,000 miles of fiber, and 120,000 small cells across the US - the infrastructure that AT&T, Verizon, and T-Mobile all lease. Unlike American Tower (global), Crown Castle is US-only, making it a pure play on US wireless infrastructure density. 5G densification - more small cells per square mile - is its multi-decade growth driver.
