What is Amazon's biggest money maker?

Amazon's largest source of revenue is its retail operations, which encompass both online and physical stores. The company's e-commerce platform allows it to sell a vast array of products directly to consumers, while also providing a marketplace for third-party sellers. This dual approach significantly boosts Amazon's sales volume. In addition to retail, Amazon generates substantial income from its subscription services, such as Amazon Prime, which offers members benefits like free shipping and access to streaming content. Furthermore, Amazon Web Services (AWS) has emerged as a critical revenue stream, providing cloud computing solutions to businesses worldwide. Collectively, these channels contribute to Amazon's financial success, but retail remains the cornerstone of its business model, accounting for the largest share of its overall revenue.
