This Chart Shows Amazon's Dominance in Ecommerce

It’s no secret that Amazon is dominant in ecommerce.

But despite this being common knowledge, the most recent data behind the explosion in Amazon’s market position is still stunning to behold: in the last two years, the already monstrous Amazon somehow was able to increase their share of the total U.S. ecommerce market from 38% to 49%.

Amazon holds almost half of the massive $252.7 billion market – that’s more than double the market share of the next nine companies (including eBay, Walmart, Best Buy, Apple, etc.) combined!


Capturing a 50% share of a coveted U.S. ecommerce market is impressive, especially considering Amazon is up against many formidable retailers:

Rank Company Market Share (2018)
#1 Amazon 49.1%
#2 eBay 6.6%
#3 Apple 3.9%
#4 Walmart 3.7%
#5 The Home Depot 1.5%
#6 Best Buy 1.3%
#7 Qurate Retail Group 1.2%
#8 Macy’s 1.2%
#9 Costco 1.2%
#10 Wayfair 1.1%

Retailers like Walmart and Best Buy are collectively throwing billions of dollars to get a foothold online. The competition is certainly fierce, but Amazon has still been able to achieve astronomical growth:

2016 2017 2018
Amazon market share 38.1% 43.5% 49.1%

Will Amazon cap out at 50%, 60%, 70%, or beyond?

At this point no one can tell – but regardless of where the growth ends, such a level of dominance has never been achieved in the retail market like this before.


Although not as stunning as overall ecommerce market share, the company’s Prime Day numbers also illustrate the vast size and scale of the company.

The most recent rendition of the annual event in July 2018 raked in $4.2 billion of revenue in a 36-hour period, even though the company had well-publicized technical issues that cost the company $72 million.
