The top online marketplaces in the world sold $1.66 trillion in 2018. Sales on marketplace sites, like those operated by Alibaba, Amazon, eBay and others, accounted for more than 50% of global web sales in 2018, according to Internet Retailer’s analysis. The growth of these sites in ecommerce is a reason many large retailers, including sportswear e-retailer Fanatics Inc., recently began selling on marketplaces. Here are the key findings of a new in-depth analysis of the just-released Internet Retailer Top 100 Online Marketplaces report and ranking.

This exclusive data of online marketplaces is offered in the 2019 Internet Retailer Online Marketplaces online database.

In addition to ranking the top 100 online marketplaces, the 2019 Top 100 Online Marketplaces Database reports up to 50 key financial, performance and corporate metrics on each one, including:
