Across two different sets of criteria, seven U.S. retailers fall in the Top 10 in 2026.
Both the National Retail Federation (NRF) and Digital Commerce 360 have released their rankings of the largest retailers in the region. The key discrepancy deciding Nos. 1 and 2 is how each set of rankings categorizes sales.
Whereas the National Retail Federation measures total sales, Digital Commerce 360 focuses purely on ecommerce. Additionally, the NRF tracks sales the retailers made in the U.S., whereas Digital Commerce 360 tracks global ecommerce sales.
Digital Commerce 360’s rankings are part of the broader Top 2000 Database. The market research tool does not limit retailers by country. Instead, it tracks North America’s largest online retailers by their annual ecommerce sales.
For example, the NRF only included Amazon’s in-store and first-party online sales. On the other hand, Digital Commerce 360 also includes both first- and third-party global online sales but not in-store sales.
And when it comes to physical retail sales in the U.S., Walmart still takes the top spot.
Comparing rankings of the Top 10 U.S. retailers in 2026
The fact that seven of the 10 largest U.S. retailers fall into both rankings indicates the importance of ecommerce in 2026 in growing retail sales. Not one of the retailers ranked in the same position across both lists.
Last year, six retailers made the Top 10 in both sets of rankings. Notably, the NRF’s Top 10 remains unchanged since then. That wasn’t the case on the ecommerce side.
Lowe’s grew its online sales enough in 2025 to push Wayfair out of the No. 10 spot in 2026. That also is what made seven retailers rank in both lists instead of six.
CVS, Walgreens and Albertsons each generate the vast majority of their sales through physical stores. Furthermore, CVS was the only retailer of that trio to have crossed the $1 billion mark in ecommerce sales for the first time in 2025. Relative to its overall $139.37 billion in 2025 sales, just over $1 billion came from ecommerce.
CVS is also the lowest-ranking retailer by ecommerce sales in both sets of rankings, and the only one ranking lower than 50 in the Top 2000 Database. It’s also the only retailer across both sets of rankings with ecommerce sales of less than $7.5 billion in 2025. The next-lowest, at that threshold, was Albertsons. However, close to 10% of its sales came from ecommerce in 2025.
Additionally, that made CVS and Albertsons the only retailers across both sets with less than $10 billion each in 2025 ecommerce sales.
Notably, Walmart made more in 2025 ecommerce than more than half of the retailers on the NRF list each made in total U.S. sales that year. Furthermore, Walmart generated more in 2025 ecommerce sales than the next seven largest online retailers combined.
And based on Digital Commerce 360’s analysis of Amazon’s sales, Amazon made more online in 2025 than any other retailer in the NRF’s Top 10 aside from Walmart. Similar to Walmart, Amazon’s ecommerce sales also amounted to more than the rest of the Top 10 combined.
