Shopify vs Amazon Sales Growth Trends: 2026 Data

Let's dig into the growth numbers. If you're betting your business on a platform, you want to know: where is the momentum?

Shopify's Growth Engine

Shopify's 2025 GMV soared to . That's not just a blip—it's a sign of sustained, global expansion. Revenue grew even faster, up 30% YoY, with international revenue up 36%. B2B GMV nearly doubled (96% growth), showing Shopify's reach beyond just DTC brands.

What's fueling this? A few things stand out:

• Personalized store control: Shopify lets brands own their customer experience, which is huge for loyalty and retention.
• Global reach: Shopify merchants now span 175+ countries, with 44% in the US, 31% in EMEA, and 16% in APAC ().
• Flexible ecosystem: App integrations, payments, and analytics are all getting more sophisticated.

Amazon's Steady, But Slower, Climb

Amazon's 2025 net sales reached . "Online stores" sales grew 9%, and "third-party seller services" (the backbone for most SMBs) grew 10.3%. Amazon is still the biggest player, but its growth rate is less than half of Shopify's.

What's slowing Amazon down?

• Marketplace saturation: More competition, tougher ad economics, and fee increases.
• Seller registration slowdown: Only ~165,000 new sellers registered in 2025, down 44% from 2024 ().
• Rising costs: FBA fees are up, and ad spend is eating into margins.

Visualizing the Growth

Here's a quick comparison:

Bottom line: Shopify is the rocket ship for growth, especially for brands that want to own their customer relationships. Amazon is still the volume leader, but the pace is cooling.

Buyer Behavior Comparison: Shopify and Amazon in 2026

Now, let's talk about what really matters: the people buying your stuff. Are Shopify or Amazon shoppers more loyal? Who spends more? Where do you build a real brand?

Shopify: The Loyalty Machine

Shopify merchants enjoy a big advantage in customer retention. The average repeat customer rate is , with top performers hitting 35% or higher. That means more than a quarter of customers come back for a second (or third, or tenth) purchase.

Why is this so high?

• Brand experience: Shopify stores control their own look, feel, and messaging. Customers remember where they bought.
• CRM and remarketing: Shopify's ecosystem makes it easy to run email, SMS, and loyalty programs.
• Personalization: Brands can tailor offers, bundles, and post-purchase experiences.

Average order value (AOV) for Shopify stores is around , with revenue per customer at $92.

Amazon: The Convenience King

Amazon's repeat purchase story is a bit different. Loyalty is to the platform, not the brand. Prime members spend and order about twice per month—double the rate of non-Prime shoppers. But they're loyal to Amazon, not necessarily to your storefront.

• Repeat purchase rate for individual sellers is closer to 20%.
• Average order value varies widely, but Amazon's scale means more frequent, smaller purchases.

The challenge? It's tough to build a direct relationship with your customer. Amazon owns the data, the communication, and the discovery.

Buyer Behavior at a Glance

Key takeaway: If you want to build a loyal customer base and maximize lifetime value, Shopify gives you the tools. If you want to tap into a massive pool of impulse buyers, Amazon is still king.

Seller Analytics Tools: Shopify Analytics vs Amazon Seller Central vs Thunderbit

Let's get nerdy for a second—because analytics is where the real edge happens.

Shopify Analytics

Shopify's built-in analytics are all about giving you a 360° view of your store:

• Sales trends: Track GMV, revenue, and conversion rates over time.
• Customer insights: See repeat purchase rates, cohort analysis, and customer lifetime value.
• Custom reports: Use ShopifyQL to dig deep into your own data, segment by product, region, or campaign.
• Visualization: Dashboards, charts, and export options for further analysis.

Shopify's analytics are especially strong for DTC brands that want to optimize for retention, AOV, and personalized marketing.

Amazon Seller Central

Amazon's Seller Central is focused on operational performance:

• Sales and traffic reports: See units sold, page views, and conversion rates.
• Inventory management: Track stock levels, FBA shipments, and restock alerts.
• Brand Analytics: For registered brands, get insights into top search terms, funnel performance, and competitor benchmarks.
• CSV exports: Download raw data for your own analysis.

Amazon's analytics are great for managing inventory and tracking performance, but less flexible for deep customer insights or cross-channel analysis.

Thunderbit: The Cross-Platform Game Changer

Here's where I get excited. is an AI-powered web scraper that lets you collect, unify, and analyze data from both Shopify and Amazon (and beyond):

• AI field suggestions: Just describe what you want ("scrape all product prices and reviews from these Shopify stores and Amazon listings"), and Thunderbit figures out the rest.

Thunderbit is especially useful for sales and operations teams who want to go beyond the built-in dashboards and see the whole market—not just their own store.

Market Share Shifts: Shopify and Amazon in the Global Ecommerce Landscape (2026)

Who's winning the ecommerce platform race in 2026? The answer depends on how you slice the data.

Shopify's Rising Star

Shopify's global market share has climbed to 10% in 2026, with US share above 14% (). That's a big jump from just a few years ago, and it's being driven by:

• Brand-building startups: Shopify is the go-to for new DTC brands and SMEs who want control.
• International expansion: Shopify's merchant base is now 56% outside the US.
• Ecosystem growth: Payments, apps, and integrations are making it easier to scale.

Amazon: Still the Giant, But Slowing

Amazon's global market share is 15%, but its growth rate is slowing—especially in mature markets like the US and Western Europe. The platform is still the first stop for many shoppers, but more brands are diversifying to avoid being "just another Amazon seller."

Market Share Table

What's the takeaway? Shopify is gaining ground, especially with startups and SMBs who want to build their own brand. Amazon is still the volume leader, but the days of "just list it and they will come" are fading.

Profitability and Seller Margins: Shopify vs Amazon Data

Let's talk money. Which platform puts more profit in your pocket?

Amazon Seller Profitability

According to :

• 57% of Amazon sellers report profit margins above 10%.
• 28% report margins above 20%.
• 13% say they're not currently profitable.
• 58% become profitable within their first year.
• Average monthly sales per seller: $11,671.
• Average profit per month (at 21% margin): ~$2,451.

But there's a catch: Amazon's fee stack is getting heavier. In 2026, FBA fees are increasing by an average of , and ad costs are rising.

Shopify Seller Profitability

Shopify doesn't publish profit margin data (it varies widely by business model), but we can estimate:

• GMV per store ranges from $4.5K–$11.3K/month depending on whether you use BuiltWith or StoreLeads for store count ().
• Fee structure: Shopify charges a monthly subscription ($39–$399+), plus card rates starting at 2.9% + $0.30 per transaction ().
• No marketplace fees: You keep more of each sale, but you have to drive your own traffic (which means more marketing spend).

Cost Structure Comparison Table

Key insight: Shopify sellers have more control over costs, but must invest in marketing. Amazon sellers face higher platform fees, but get built-in traffic.

Strategic Implications: Data-Driven Platform Choice for SMBs in 2026

So, what does all this mean for small and mid-sized businesses? Here's my take, based on the data and what I see in the field:

• Shopify is best for brands that want to build long-term customer relationships, control their data, and optimize for repeat purchases. The flexibility and analytics depth make it easier to test, learn, and grow.
• Amazon is unbeatable for instant reach and scale, but you're renting customers, not owning them. The trade-off is less control, higher fees, and more competition.
• The smartest teams are going multi-channel. They use Shopify for brand-building and retention, Amazon for volume and discovery, and unify their data to optimize both.

Pro tip: Don't pick a platform based on gut feeling. Use data—repeat purchase rates, margin analysis, and competitive monitoring—to guide your strategy. That's where AI tools like Thunderbit come in.

Here's where Thunderbit shines. As an , Thunderbit lets you collect and harmonize data from both Shopify and Amazon (and even your competitors):

Key Takeaways: Shopify vs Amazon Seller Data in 2026

1. Shopify is growing faster than Amazon in 2026, especially among startups and SMBs. Its 29% YoY GMV growth outpaces Amazon's 12%.
2. Shopify sellers enjoy higher repeat purchase rates (28–35%) and more control over customer relationships. Amazon sellers benefit from massive reach but face lower brand loyalty.
