US Ecommerce Sales 2017: The Top 10 Companies

Executive Summary

eMarketer estimates that US retail ecommerce sales will grow 15.8% in 2017 to reach $452.76 billion, making up 9.0% of total retail sales. Retail ecommerce sales from the top 10 US companies ranked in that category will hit $289.86 billion this year.

• Amazon is responsible for an outsized proportion of total ecommerce sales. When Amazon’s sales are combined with ecommerce sales from eBay and Walmart—the next two companies on the list—they represent almost 5% of total retail sales in the US.
• While the top two companies are for the most part online-only retailers, 60% of the biggest ecommerce players are multichannel, with a majority of sales occurring in-store.
• No sector dominates the top 10. Discount and variety, department stores, electronics, home goods and home improvement are all represented.
• A number of mergers and acquisitions occurred in 2017, due in part to retailers buying companies and creating partnerships to stay competitive with Amazon. Several more acquisitions are likely on the horizon.
