Amazon

Amazon's market cap of ~$2.3 trillion reflects its dual identity as the world's largest e-commerce platform and the undisputed leader in cloud computing through AWS, which alone generates more than $100 billion annually. CEO Andy Jassy has overseen a dramatic cost restructuring that restored Amazon's profitability to record levels while investing aggressively in generative AI through Bedrock, its managed AI services platform. Amazon's logistics network, now including its own air cargo fleet and last-mile delivery infrastructure, is increasingly becoming an autonomous competitive moat.
