Amazon is leading the competition for fulfillment centers and last-mile delivery locations, and the e-commerce behemoth is also pushing the new supply pipelines as developers scramble to complete large facilities.

"When it comes to e-commerce, there is Amazon and then there is everyone else," notes a recent report from CommercialEdge on the state of the industrial sector. "Between the behemoth's direct sales to consumers and third-party sales through its platform, it is by far the dominant force in online retailing. Even as other companies, like Wal-mart, surpassed it in e-commerce growth in 2020, they are still playing catch-up."

Many of the largest spaces in the CommercialEdge Industrial database include an Amazon lease, including the 3.8 million square foot LogistiCenter at I-95 Wilmington, which is currently under development in Philadelphia. Similar facilities are underway in Austin, Detroit, Syracuse, and  Little Rock. And nationwide, Amazon distribution centers will account for 8 of the top 10 largest industrial projects underway in the US this year, with a total footprint of 28.3 million square feet—an area about the size of New York City's Central Park.
