About American Tower
American Tower is a real estate investment trust that owns and operates communications infrastructure. Its core business is leasing space on its global portfolio of wireless towers to mobile carriers under long term contracts, a model built on steady, recurring rent.
Its AI relevance comes from CoreSite, the US data center platform it acquired. CoreSite operates interconnection dense colocation facilities in major metro markets, where cloud providers, networks, and enterprises exchange traffic directly. AI and cloud connectivity demand supports leasing and interconnection growth across those campuses, though towers remain the dominant business.
Founded in 1995 and headquartered in Boston, Massachusetts, American Tower employs about 4,866 people and trades on the NYSE.
American Tower in the AI buildout
American Tower touches the Data Centers layer through CoreSite, whose metro colocation campuses serve as interconnection hubs where clouds, carriers, and enterprises meet. AI raises the value of that positioning: inference traffic and hybrid deployments need low latency exchange points near users, which is what CoreSite sells. The rest of the portfolio, a global base of wireless towers, sits outside the buildout, making American Tower a tower REIT with a data center kicker rather than an AI infrastructure play.
AMT is tracked in Data Centers & Hardware, rated Growing on the AI Exposure leaderboard.
