Overview

Amazon has led US ecommerce for over a decade, but Walmart Marketplace is its most credible challenger. With massive physical retail presence and growing online traffic, Walmart is impossible for serious sellers to ignore.

Amazon offers sheer scale, FBA logistics, and the Prime ecosystem. Walmart counters with lower fees, less seller competition, and the world's largest retailer brand halo. WFS is maturing as a credible FBA alternative.
