Top Ecommerce Companies in the USA: The 100 Brands Winning the Traffic Race in 2026

Month one, 2025 is done. And wow — what a start! New challenges, new opportunities, and some seriously powerful Similarweb updates to keep you ahead of the pack.
First, let’s talk about some of the moments that shook up January:
But while the industry was shifting, we were busy rolling out some exciting updates. From expanded market share insights and smarter dashboards to intuitive sales prospecting tools, you have everything you need for a successful start to 2025.
Think you know your competitors? Think again. Analyzing just one of their domains can give you a misleading picture of their true market power.
Now, with the latest update to Market Analysis, you see total traffic across all domains owned by a competitor — so you’re never guessing.

Now, with the latest update to the Players page in Market Analysis, you get the whole picture. This feature reveals total traffic across all domains owned by an industry player in a specific country.
Why this matters. You can:
Consumer demand is like the tide — it rises and falls, shifts in direction, and varies from one place to another.

That’s why we’ve supercharged our Demand Analysis tool to make trend-tracking effortless. Here’s what’s new:
Data is only as useful as the way it’s presented.
That’s why we’ve introduced Custom Dashboards — a flexible way to visualize and interact with Similarweb data in a format that works for you.

With this update, you can:
Whether you’re tracking performance, benchmarking competitors, or presenting insights to stakeholders, Custom Dashboards turns raw data into actionable intelligence — faster and more efficiently than ever.
Keeping tabs on who’s winning the search results page just got even easier. We’ve introduced new filters in our SERP Players and Pages reports, giving you more control over how you analyze competitive performance.
Now, you can track growth and decline trends over time, spot shifts in rankings, and isolate specific competitors or platforms like Reddit to see who’s capturing the traffic you’re after.
Hunting for new prospects? You can waste time searching domain by domain. Or… you can use our new Company Tab in Sales Intelligence.
The Company Tab eliminates the guesswork. Instead of searching domain by domain, you can now look up an entire company and instantly access all of its regional websites in one place. This streamlined view helps you see the full scope of their online presence with just one click.
Why this matters. You can:
We have big things planned for 2025, starting with tools that give you clearer insights and more control over your digital strategy.
First up is our Ad Intelligence Suite, designed to help you analyze ad performance and track publisher and advertiser activity.
We’re also introducing App Intelligence as a standalone tool, making it simpler to uncover app performance trends and market opportunities. On top of that, Retail Intelligence is getting an upgrade, offering a deeper understanding of consumer behavior to refine your ecommerce approach.
And this is just the beginning — more updates and enhancements are always in the pipeline.
