With an estimated $441 billion in worldwide retail e-commerce sales, Amazon is a clear leader in the digital marketplace. The tech giant is forecasted to account for 47% of U.S. retail e-commerce sales in 2019, making it the largest e-commerce platform in the country, according to eMarketer. Shares of amazon are worth more than 5 times what they were trading at five years ago, but now many investors are searching for the "next amazon" in other corners of the world, hoping that they will replicate Amazon and Jeff Bezos' success.
