eMarketer released an ecommerce forecast that ranks, for the first time, the top ecommerce retailers in the US. Together, eMarketer estimates, the top 10 retailers will make up nearly two-thirds of all US retail ecommerce sales in 2017.
Overall, eMarketer estimates that US retail ecommerce will grow 15.8% in 2017 to reach $452.76 billion, making up 9.0% of total retail sales. By comparison, the ecommerce growth rate of the top 10 companies combined will total 27.3% in 2017.
Not surprisingly, Amazon sits at the top spot of the ranking, with more than 6 times the projected sales of No. 2 eBay. Amazon's ecommerce growth rate is estimated to be 32.0% this year, roughly double the pace of overall ecommerce growth.
But Amazon won't log the fastest growth among the top 10 companies. Both Walmart (46.9%) and Wayfair (41.4%) will outpace Amazon this year, albeit from much smaller bases.
