American Tower Continues Its Global Domination

American Tower (NYSE: AMT) is a behemoth in the real estate investment trust (REIT) sector. The communications-focused infrastructure REIT currently clocks in at a nearly $100 billion market cap, more than $25 billion above the next-largest REIT, industrial giant Prologis (NYSE: PLD). American Tower has grown to such a large scale by gobbling up cell towers in the U.S. and expanding overseas, becoming the largest global tower operator.
