How Amazon Makes its Money: Revenue Breakdown

How Does Amazon Make its Money?

Amazon generates revenue through six distinct business lines, but the critical insight for understanding the company is that revenue and profit come from very different sources. E-commerce (online stores and third-party seller services) generates the most revenue — about 62% of the $716.9 billion total — but operates on razor-thin margins where a good quarter means 2-3% profit. The real profit engines are Amazon Web Services (AWS) and advertising, which together contributed roughly 80% of operating income despite representing only 28% of revenue.

This dual nature is central to Amazon’s strategy. The retail business acquires hundreds of millions of customers and generates massive transaction volume at near-breakeven margins. AWS and advertising then monetize Amazon’s infrastructure and audience at dramatically higher margins. It is, in effect, an advertising and cloud company that runs the world’s largest retail operation as a customer acquisition channel.

In FY2025, Amazon reported $716.9 billion in total revenue (up 12.4%) and $77.7 billion in net income — more than doubling the $36.3 billion earned just two years earlier.

Amazon (AMZN) Business Model

Amazon’s business model is architecturally unique among large companies. Jeff Bezos built the company around a flywheel concept: lower prices attract more customers, more customers attract more third-party sellers, more sellers expand selection, greater selection and competition drive prices lower still. At each turn of the flywheel, Amazon captures fees (seller commissions, FBA fulfillment charges, advertising) while spreading infrastructure costs across ever-larger volumes.

The flywheel creates a powerful economies of scale advantage that compounds over time. Amazon’s fulfillment network — over 1,000 facilities worldwide, including sort centers, delivery stations, and last-mile hubs — would cost tens of billions and take a decade for any competitor to replicate. Similarly, AWS’s data center footprint and the customer trust embedded in the Prime membership (200+ million members paying $139/year) represent durable competitive moats.

Amazon reinvests aggressively. Capital expenditure reached $128.3 billion in FY2025, primarily directed toward AWS data centers and AI infrastructure (including Amazon’s custom Trainium and Inferentia chips). This investment level exceeds the total revenue of most Fortune 500 companies and reflects Amazon’s bet that AI workloads will drive the next wave of cloud growth.

Amazon Competitors

Amazon’s competitive landscape is fragmented across its business lines. In e-commerce, Walmart is the closest overall competitor, with a growing online operation and unmatched physical store footprint. Shopify enables millions of independent merchants to compete with Amazon’s marketplace by running their own online stores. In cloud computing, Microsoft’s Azure (25% market share) and Alphabet’s Google Cloud (11%) compete with AWS (31%). In advertising, Amazon’s ad platform competes with Google and Meta for retail-related ad budgets, and it has rapidly become the third-largest digital ad platform globally.

The competitive dynamic is evolving. China-based platforms like Temu (owned by PDD Holdings) and Shein have disrupted low-end e-commerce with direct-from-factory pricing, pressuring Amazon on price-sensitive categories. In cloud, the AI boom has intensified competition as each hyperscaler races to attract AI workloads with custom chips and exclusive model partnerships — AWS with Anthropic, Azure with OpenAI, Google Cloud with Gemini.

Revenue Breakdown

Online Stores — 38% of Revenue

Direct retail sales where Amazon buys inventory from brands and wholesalers, warehouses it in its fulfillment centers, and ships it to customers. This is the classic Amazon shopping experience — the “Sold by Amazon” listings. Online Stores generated $269.3 billion in FY2025, growing 9%. Margins are deliberately thin (estimated 1-3%) because Amazon prices aggressively to maximize customer acquisition and flywheel velocity. The real monetization comes from the higher-margin services that sit on top of this retail infrastructure.

Third-Party Seller Services — 24% of Revenue

More than 60% of units sold on Amazon come from third-party sellers, not Amazon itself. These sellers pay Amazon referral fees (typically 8-15% of the sale price), Fulfillment by Amazon (FBA) fees for warehousing and shipping, and increasingly, advertising fees to get their products seen. Third-Party Seller Services generated $172.2 billion in FY2025, growing 10.3%. This is significantly higher-margin than first-party retail because Amazon earns fees without bearing inventory risk — the seller owns the product; Amazon provides the platform and logistics.

AWS — 18% of Revenue

Amazon Web Services is the world’s largest cloud computing platform with roughly 31% market share. AWS generated $128.7 billion in FY2025 revenue, up 19.7%, and $45.6 billion in operating income — meaning AWS alone accounted for 57% of Amazon’s total operating profit despite being only 18% of revenue.

AWS offers over 200 services, from basic compute instances (EC2) and object storage (S3) to fully managed databases (RDS, DynamoDB), machine learning services (SageMaker, Bedrock), and generative AI APIs. Customers include startups, enterprises, and government agencies, with remaining performance obligations (contracted backlog) of $244 billion providing exceptional revenue visibility.

Advertising — 10% of Revenue

Amazon’s advertising business generated $68.6 billion in FY2025, growing 22.1% — the fastest growth rate among Amazon’s major segments. When a shopper searches for “running shoes” on Amazon, the top results are often Sponsored Products — advertisers pay per click to appear prominently. Sponsored Brands and display ads extend this model. The advertising business is extraordinarily high-margin because it runs on existing Amazon shopping infrastructure and captures demand from consumers who already intend to buy. Amazon is now the third-largest digital advertising platform globally, behind Alphabet’s Google and Meta.

Prime Subscriptions — 7% of Revenue

Prime membership revenue reached $49.6 billion in FY2025, growing 11.8%. Prime ($139/year or $14.99/month) offers free two-day shipping, Prime Video streaming, Prime Music, Prime Reading, and other benefits. With over 200 million members globally, Prime serves as the glue holding the Amazon ecosystem together — Prime members spend 2-3x more on Amazon than non-members, creating a powerful retention and monetization loop.

Income Statement Overview

Amazon’s $80 billion in operating income on $716.9 billion in revenue represents an 11.2% operating margin — seemingly low compared to software peers, but a record high for Amazon and a dramatic improvement from the 2-5% margins that characterized the company for most of its history. The margin expansion has been driven by the growing mix of high-margin businesses (AWS at 35.4% operating margin, advertising at an estimated 50%+ margin) outpacing the low-margin e-commerce segments.

Net income of $77.7 billion was boosted by $17.3 billion in non-operating income, primarily from mark-to-market gains on Amazon’s investments in Anthropic (the AI startup behind Claude) and Rivian (the electric vehicle maker).

Key Financial Metrics

• Operating Margin: 11.2% — A record for Amazon, up from 10.8% in FY2024. While this looks modest compared to pure-play software companies, it represents a tectonic shift for a company that deliberately ran at near-breakeven margins for two decades. If margins continue expanding 50-100 basis points per year as the advertising and cloud mix grows, Amazon could reach 15%+ operating margins within a few years.

• AWS Operating Margin: 35.4% — AWS is a cash machine, generating $45.6 billion in operating income. This margin has expanded steadily as older data center investments depreciate while per-unit costs decline on newer, more efficient infrastructure. AWS alone would rank as one of the most profitable companies in the S&P 500.

• Advertising Growth: 22.1% — Amazon’s ad business added $12.4 billion in incremental revenue year-over-year, outpacing even Meta’s ad growth rate. The introduction of ads on Prime Video in early 2024 opened a new inventory source with demonstrated engagement.

• Capital Expenditure: $128.3B — Amazon spent more on capex than most countries spend on their entire technology sectors. The majority went to AWS data centers and AI infrastructure, including the buildout of Trainium2 chip clusters. This level of spending will suppress free cash flow in the near term but positions AWS for the AI infrastructure wave.

Is Amazon Profitable?

Amazon is highly profitable and its profitability is accelerating. The $77.7 billion in net income in FY2025 represents a 31% increase from FY2024’s $59.2 billion and a 114% increase from FY2023’s $36.3 billion. The company has moved decisively beyond its historic reputation as a growth company that sacrificed profits for expansion.

The profitability will look inflated in FY2025 due to $17.3 billion in non-operating gains from investment revaluations (primarily Anthropic). On a pure operating basis, the $80 billion in operating income is the cleaner measure and shows an 11.2% operating margin that is structurally expanding.

What to Watch

1. AI infrastructure ROI — Amazon spent $128.3 billion in capex in FY2025, with plans to maintain or increase this level. AWS has a $244 billion backlog, but the question investors are debating is whether returns will justify the investment magnitude. If AI workloads grow as expected, AWS stands to capture a large share. If AI spending cycles slow, the overcapacity could pressure margins.

2. Anthropic partnership — Amazon has invested an estimated $8+ billion in Anthropic, the AI company behind Claude. This investment is already marked at $7.7 billion above cost on Amazon’s books. Anthropic’s models are integrated into AWS’s Bedrock AI service, giving AWS a proprietary AI offering to compete with Microsoft’s OpenAI integration on Azure and Google’s Gemini on GCP.

3. Advertising margin expansion — At $68.6 billion and growing 22%, advertising is approaching AWS in strategic importance. The introduction of ads on Prime Video unlocked a new high-CPM inventory source. If Amazon continues to expand ad placements (search, product pages, Prime Video, Twitch, Fire TV), advertising revenue could exceed $100 billion annually within two to three years.

4. Regulatory and trade risk — Amazon settled an FTC lawsuit for $2.5 billion in FY2025, but regulatory scrutiny remains elevated globally. Evolving U.S. trade policies and tariffs on internationally sourced goods could pressure costs for both Amazon’s first-party retail business and its third-party sellers.

5. International profitability inflection — Amazon’s international segment reached $4.8 billion in operating income in FY2025, up from $3 billion the prior year. Historically, the international business was a consistent money-loser as Amazon invested heavily in logistics networks across India, Europe, and other markets. If international margins continue converging toward North American levels, it represents a significant earnings catalyst.

Amazon (AMZN) Financial Summary

Amazon (AMZN) generated $716.9 billion in total revenue in fiscal year 2025, growing 12.4% year-over-year. Net income reached $77.7 billion with operating income of $80 billion at an 11.2% operating margin — a record. AWS ($128.7B revenue, 35.4% operating margin) and advertising ($68.6B revenue, 22% growth) are the profit engines, while e-commerce provides massive scale and customer reach at lower margins. Amazon’s $128.3 billion in capital expenditure reflects one of the largest AI and cloud infrastructure investments in corporate history.
