Amazon Ads Hit 10% of Revenue as AWS and Ecommerce Drive 10% Growth

AMZNAMZN

Amazon’s online sales rose 10% year-over-year in Q3 2025 versus Walmart’s 5.8%, while AWS and advertising units generated $33 billion and $17.7 billion respectively, with ads accounting for nearly 10% of revenue. At its current 10% ecommerce and 22% AWS growth rates, Amazon forecasts reaching over $1 trillion in annual revenue by 2028.

1. Amazon’s Accelerated Online Revenue Growth

Amazon’s e-commerce segment continues to outpace traditional retail, with online sales rising 10% year-over-year in the latest quarter compared to a 5.8% increase in total revenue at its leading competitor. This acceleration reflects strong consumer adoption of Amazon’s platform, driven by expanded Prime membership benefits and enhanced personalization tools. Investors should note that this growth rate positions Amazon to capture a larger share of digital retail spend even as overall consumer demand moderates.

2. Diversified High-Margin Businesses Fuel Profit Expansion

Beyond its online marketplace, Amazon’s high-margin operations are scaling rapidly. Amazon Web Services reported a 20% year-over-year revenue increase, propelled by surging demand for AI computing resources and enterprise cloud services. Concurrently, Amazon’s advertising division generated $17.7 billion in revenue last quarter—nearly 10% of total sales—versus under 1% at its main physical-store rival. These segments collectively drive consolidated gross margins above 50%, offering investors exposure to both structural e-commerce growth and profitable technology platforms.

3. Long-Term Logistics Investments Support Competitive Moat

Amazon has expanded its fulfillment infrastructure to over 1,300 shipping facilities and more than 500 physical grocery outlets since acquiring Whole Foods, investing over $60 billion in logistics over the past two years. While still smaller in store count than traditional operators, these assets underpin Amazon’s ability to offer next-day and same-day delivery to over 85% of U.S. households. Such capabilities reinforce customer loyalty and create high barriers to entry in fast-delivery commerce, underpinning durable revenue streams and justifying the company’s continued capital allocation to network expansion.
