How Many eCommerce Sites Are There in 2025?

There are more than 24 million eCommerce sites worldwide, and while new sites are still being created daily, the growth trend has recently shifted.

The eCommerce landscape has exploded in recent years, and the numbers speak for themselves:

Take a look at this chart:

In 2019, there were 9.2 million eCommerce sites. Fast-forward to 2025, and there are a staggering 24.1 million.

Even with a recent dip, that’s still more than double what we saw in 2019.

But here’s the kicker:

The year-over-year (YoY) growth rate has had its ups and downs:

So, what’s driving these fluctuations?

eCommerce is still a massive market with over 24 million sites worldwide, but growth patterns can vary year to year.

While the pandemic triggered unprecedented expansion, the sector is now finding its footing in a more mature and competitive landscape.

Wondering which countries dominate the eCommerce space?

Here’s the lowdown:

These numbers reveal a fascinating trend: while traditional markets grow, emerging markets quickly catch up.

A Quick Overview of the Top 3 Countries

When it comes to eCommerce, a few countries are leading the pack.

Let’s dive into the top three and see what makes them stand out.

How Many eCommerce Sites Are There in the US?

The rise of eCommerce in the United States has been nothing short of phenomenal—but in recent years, the growth trend has taken a turn.

As of 2025, the United States has 11.9 million eCommerce sites, reflecting a -13.1% change from the previous year.

Despite the downturn, the total number of sites remains significantly higher than pre-pandemic levels, signaling that the market is still substantial. However, it appears to be entering a period of consolidation.

Here’s how the number of eCommerce sites has evolved over time:

Despite these recent declines, the overall US eCommerce landscape is still vastly larger than it was in 2019.

The market appears to be entering a mature phase, where rapid expansion is giving way to consolidation and strategic recalibration.

As consumer behavior continues to evolve, the most adaptable eCommerce businesses will maintain or grow their share, even while others exit or pivot to different business models.

A Snapshot of the UK eCommerce Growth

Next, we turn our attention to the United Kingdom.

As of 2025, the UK has 1.1 million eCommerce sites, reflecting a -15.4% change from 2024.

While this marks a dip, the overall number of online businesses remains significantly higher than it was just a few years ago, indicating that the market is experiencing a period of consolidation rather than a long-term decline.

Here’s how the numbers have changed over time:

2022 to 2023: Another significant leap to 1.2 million sites, a 45.9% increase, solidifying the UK’s position as an eCommerce powerhouse.

Despite the recent downturn, the UK eCommerce sector remains vibrant and is vastly larger than it was in 2019.

As the market transitions from rapid growth to a more mature, competitive environment, we can expect periodic fluctuations and consolidations while still offering ample opportunity for businesses that adapt to evolving consumer demands.

Brazil’s eCommerce Boom and Recent Correction

Now, let’s head over to Brazil, where the eCommerce sector has experienced a significant boom over the past few years—followed by a recent market correction.

As of 2025, Brazil has 0.7 million eCommerce sites, reflecting a -12.5% change from 2024.

Despite this dip, the market remains considerably larger than it was just a few years ago, highlighting the country’s still-strong foundation of online business.

Here’s how the numbers have shifted over time:

Despite the recent downturn, Brazil’s eCommerce sector is still significantly larger than it was in 2019.

The market appears to be moving from a phase of explosive growth to one of refinement and consolidation, where established players are consolidating their positions and some smaller ventures may be exiting or merging.

This evolution is normal in a maturing market, and it sets the stage for more sustainable, long-term growth going forward.

Conclusion and Key Takeways

1. Consolidation is Underway
   • In 2025, eCommerce site counts dropped by -13.1% in the US, -15.4% in the UK, and -12.5% in Brazil. These simultaneous dips signal a “shakeout,” where only stronger or more innovative players survive.
2. From Quantity to Quality
   • The frantic surge of 2021 (where the UK jumped 211.5% and Brazil soared 263.6%) is now giving way to fewer but more resilient stores focused on profitability and customer experience.
3. Global Patterns Converge
   • The transition from explosive pandemic-era growth (up to 204% YoY in some markets) to moderate or negative rates in 2024–2025 shows that even emerging regions are catching up fast, then leveling off like established markets.
4. Innovation May Accelerate
   • A leaner field often triggers higher-tech solutions—from AI-powered recommendations to advanced fulfillment options—because remaining players need to outdo each other for a share of a more discerning consumer base.
5. Specialization Over Generalization
   • General marketplaces still dominate, but niche eCommerce sites can thrive by offering depth rather than breadth, especially as consumers seek personalized experiences and curated product lines.
