Amazon vs eBay vs Walmart: Which Marketplace Should Sellers Choose in 2025?

With e-commerce booming in 2025, sellers have more opportunities than ever to grow their businesses online. However, one of the most common questions new and experienced sellers face is: Should I sell on Amazon, eBay, or Walmart?

Each platform has its own advantages, disadvantages, and customer base. In this guide, we’ll break down the differences between Amazon, eBay, and Walmart Marketplace so you can decide which one is right for your business.

Selling on Amazon: The Leader in Online Retail

Amazon is the world’s largest marketplace, with millions of active shoppers who trust the brand for quick delivery and quality service.

Advantages:

Massive Audience: Amazon dominates the U.S. e-commerce market, attracting customers in almost every niche.
Fulfillment by Amazon (FBA): Sellers can outsource storage, shipping, and customer service.
Customer Trust: Shoppers often start their search directly on Amazon, which boosts conversion rates.

Drawbacks:

Intense Competition: Thousands of sellers compete for the same keywords and categories.
High Fees: Between referral and fulfillment fees, profit margins can shrink quickly.
Strict Guidelines: Even minor policy violations can result in account suspension.

Selling on eBay: The Flexible Alternative

eBay has been around since the early days of e-commerce and continues to attract buyers looking for deals, second-hand goods, and collectibles.

Advantages:

Diverse Product Range: From auctions to brand-new items, sellers have more freedom with listings.
Global Reach: eBay is available in nearly every country, making it easy to sell internationally.
Lower Starting Costs: Easier for beginners compared to Amazon or Walmart.

Drawbacks:

Less Trust for New Sellers: Without strong feedback, it can be harder to gain traction.
Self-Fulfillment: No built-in FBA-like option, meaning sellers handle logistics.
Price-Sensitive Buyers: Many eBay shoppers expect discounts, which can reduce profits.

Selling on Walmart Marketplace: The Rising Competitor

Walmart Marketplace is growing quickly as the company continues to expand online. While it’s smaller than Amazon and eBay, it offers unique advantages.

Advantages:

Lower Competition: Fewer sellers mean more room for visibility.
Strong Brand Name: Walmart is one of the most trusted retailers in the U.S.
Affordable Fees: Referral fees are generally lower than Amazon’s.

Drawbacks:

Tough Approval Process: Not every seller gets accepted.
U.S.-Focused: International sellers have limited opportunities.
Still Developing: Tools and seller features are less advanced compared to Amazon.
