Amazon -- How the Business Works

Amazon operates three reinforcing business pillars: E-Commerce (North America and International stores), AWS Cloud (the world's largest cloud infrastructure provider), and Advertising (the third-largest digital ad platform in the U.S.). Revenue totaled $717B in FY2025, with operating income expanding from $12.2B (FY2022) to $80.0B (FY2025) -- a 6.5x improvement under CEO Andy Jassy. The Prime membership program (200M+ members) acts as a flywheel connecting all three pillars, generating purchase data that powers advertising while funding massive AWS/AI investment.

Business model flow -- how the pillars reinforce each other
Step 1
E-Commerce Generates Data
200M+ Prime members generate trillions of shopping, browsing, and streaming signals. $588B in store revenue (N. America + International) creates the largest 1P purchase dataset in the world. 62% of units sold by 3P sellers amplify data breadth.
Step 2
Data Powers Advertising ($69B)
Purchase intent data enables closed-loop attribution that Google and Meta cannot match. Sponsored products, Prime Video ads (315M+ viewers), and Amazon DSP convert shopping signals into the fastest-growing high-margin revenue stream (+22% YoY, ~20.9% 2-year CAGR).
Step 3
Advertising Funds AWS Investment
High-margin advertising revenue ($69B at estimated 50%+ operating margins) funds the unprecedented $125B capex in 2025 and $200B guided for 2026, almost entirely directed at AWS data center and AI infrastructure expansion.
Step 4
AWS Enables AI ($129B, ~35% Op Margin)
AWS holds ~31% cloud market share with $244B backlog (+40% YoY). Custom silicon (Trainium, Graviton) provides structural cost advantages. Bedrock AI platform growing 60% QoQ. AWS generated $45.6B operating income in FY2025 -- more than most companies earn in revenue.
Step 5 -- Cycle Repeats
AI Improves E-Commerce → Back to Step 1
Rufus AI shopping assistant (300M users) drives $10B+ incremental annualized sales with 60% higher purchase rates. Alexa+ doubles engagement and quadruples shopping conversions. 1M+ robots optimize fulfillment. AI-driven improvements bring more customers into Prime, restarting the flywheel.
How each business works

E-Commerce (82% of revenue). Amazon operates the world's largest online marketplace across North America ($426B) and International ($162B) segments. Revenue comes from two models: first-party retail (Amazon buys and resells inventory, $269B) and third-party marketplace (sellers list products and Amazon collects commissions, fulfillment fees, and shipping revenue, $172B). The 3P mix has reached 62% of units -- the highest ever -- making the business increasingly capital-light. Amazon has built an unmatched logistics network with 1M+ robots, delivering 9B+ units same/next-day globally. Grocery ($150B+ gross sales) and quick commerce (30-minute delivery) are extending the total addressable market. Prime membership ($49.6B subscription revenue) locks in repeat purchases and provides predictable recurring revenue.

AWS Cloud (18% of revenue, ~57% of operating income). Amazon Web Services is the world's largest cloud infrastructure provider with ~31% market share, ahead of Azure (~22%) and Google Cloud (~11%). AWS generated $129B in revenue growing 20% YoY, with $45.6B in operating income at ~35% margins. The business provides compute, storage, database, AI/ML, and networking services to millions of customers. AWS has been the Gartner cloud leader for 15 consecutive years. The $244B backlog (+40% YoY) provides exceptional revenue visibility. Custom silicon (Trainium AI chips and Graviton CPUs, >$10B run rate growing 100%+) provides a structural cost advantage versus competitors reliant on third-party GPUs. Bedrock, the managed AI platform, is growing 60% quarter-over-quarter.

Advertising (10% of revenue, highest growth). Amazon's advertising business has grown from $31B (FY2021) to $69B (FY2025) -- 2.2x in four years. It is the third-largest digital advertising platform in the U.S. with ~15% share, behind only Google and Meta. The business benefits from a unique structural advantage: Amazon has first-party purchase data and closed-loop attribution that no competitor can replicate. When a shopper sees a sponsored product ad and buys it, Amazon can directly measure the return on ad spend. Prime Video ads reach 315M+ global viewers, and the Amazon DSP combined with a Roku partnership creates the largest connected TV advertising footprint in the U.S. Advertising is estimated to carry 50%+ operating margins, making it the highest-margin business within Amazon and a critical funding source for the company's massive infrastructure investments.
