There are plans to open six more by the end of the year, and up to 50 stores in 2019.
Amazon Go threatens traditional convenience store companies like 7-Eleven, as well as chain fast food sandwich and lunch chains like Subway. Some of the shops only offer a limited selection of salads, sandwiches and snacks, while others have a small selection of groceries, making it more akin to a convenience store.
Why it matters: While Amazon has ruled the e-tailer business for the past few years, physical stores represent a considerable investment which Jeff Bezos is willing to undertake for longer-term profitability.
Amazon has been quite cautious in its roll-out of Amazon Go stores that replace the cashier with a smartphone app. Since then, the company has opened two more Seattle sites and one in Chicago, and has confirmed plans for San Francisco and NY stores.
A 3,000-store footprint would catapult Amazon into the ranks of America's major physical retail chains. For comparison, there are close to 67,000 7-Eleven locations around the globe. Adding 3,000 convenience stores would make AmazonGo among the biggest such chains in U.S.
Shares of big grocers slipped in response to the report Wednesday. Walmart declined as much as 0.6 percent, reversing an earlier gain, while Target Corp. dropped about 1.5 percent and Kroger Co. slid as much as 3.1 percent.
Those companies had already been on notice for more than a year after Amazon bought its way into brick-and-mortar groceries with the $13.5 billion acquisition of more than 470 Whole Foods Market stores. The third location opened a week later in one of Amazon's office buildings at 300 Boren Ave.
What's more, Amazon has grown its advertising business 242 percent since 2017, eMarketer said.
"We have no plans to open 2,000 of anything", a spokesperson said a few days after the newspaper's story published.
Amazon Go is going national.
AmazonGo outlets each use hundreds of cameras and sensors to detect what customers take off shelves and bill their credit card accounts.
The original AmazonGo in downtown Seattle required more than $1 million in hardware alone, a person familiar with the matter has said.
