Alibaba and Amazon are the two largest e-commerce companies in the world. While Alibaba sells more goods overall, Amazon generates higher fees from sales. However, Alibaba is significantly more profitable due to its business model of facilitating product exchanges through online platforms rather than directly selling goods like Amazon, which incurs higher costs from logistics and warehouses. Going forward, both companies have a strong hold on their home markets of China and the US, and it remains to be seen how they may compete as Alibaba expands globally.
