$Amazon.com(AMZN)$ Amazon isn't just an e-commerce giant. Its retail marketplace has a serious logistical moat and massive customer reach, but the real story is what sits underneath. AWS powers a big chunk of cloud computing and generative AI infrastructure with high margins, and the advertising business is turning into a real monetization engine at the point of purchase. The company keeps using cash flow from its consumer operations to fund and scale those higher-margin tech and logistics segments, so it ends up acting less like a traditional retailer and more like a compounding machine built on global trade, enterprise technology, and consumer habit.
