With the opening of its first large-format cashier-less grocery store in Seattle on Tuesday, Amazon is on its way to further expanding its physical footprint across U.S. cities.

The big picture: Amazon’s 2017 purchase of Whole Foods was never the end of its grocery ambitions — or its fight to win a bigger share of the whopping $700 billion per year American grocery industry.
