Amazon.com Inc.
A two-sided flywheel pairs a low-margin commerce engine with high-margin cloud, ads, and subscriptions, letting scale and data subsidize faster delivery, broader selection, and stickier customer loyalty.
Business Overview
Amazon runs a global commerce-and-compute platform across three segments — North America, International, and AWS — with trailing-twelve-month sales of $742.8B as of March 31, 2026. Low-margin retail (online and physical stores, third-party seller services) drives volume, while high-margin AWS ($137B TTM, +28% in Q1 2026), advertising (>$70B TTM), and subscriptions supply the profit. Over 1.5 million employees support retail, logistics, and data centers.
Revenue Model
Customers pay through direct product sales, marketplace take-rates on third-party transactions, recurring Prime subscriptions, usage-based cloud consumption, and advertising sold against shopping intent. Switching costs rise through Prime benefits, seller tooling, fulfillment integration, and embedded cloud workloads.

Breakdowns
Revenue Mix
Competitive Moat
The closest competitor is Walmart, but Amazon combines marketplace scale, logistics reach, and AWS cash generation in one system. Third-party sellers now account for over 60% of units sold, which deepens selection and improves capital efficiency.
Competitive Landscape
Walmart
Competes in retail breadth and fulfillment speed, but lacks Amazon’s cloud profit pool and marketplace software ecosystem.
Microsoft
Competes most directly in cloud, but does not match Amazon’s consumer marketplace, seller network, or retail ad engine.
Alphabet
Competes in digital ads and cloud, but lacks Amazon’s commerce transaction data and fulfillment integration.
Growth Drivers
+28% YoY
AWS reacceleration
AWS grew 28% to $37.6B — its fastest in 15 quarters — as generative-AI workloads lifted infrastructure consumption.
>$70B TTM
Advertising scale
Advertising surpassed a $70B trailing-twelve-month run-rate as shopping-intent data improves ad relevance and conversion.
>$20B run-rate
Custom silicon
Amazon-designed Trainium/Graviton/Nitro chips topped a $20B run-rate (triple-digit growth), with OpenAI and Anthropic committing gigawatts of Trainium.
60%+ units
Third-party mix
Third-party sellers are over 60% of units sold, expanding selection without proportional inventory risk.
Risk Factors
Antitrust litigation
An FTC case targeting Amazon marketplace practices could impose operating constraints; trial timing has shifted and remains pending.
$1.2B FCF
Capex / FCF pressure
AI-driven capex (Q1 alone $44B) cut trailing free cash flow to $1.2B, down 95% — returns hinge on AWS AI monetization.
~30% share
Cloud competition
AWS leadership can narrow if Azure and Google Cloud price aggressively or win more AI workloads.
Key Developments
April 2026
Q1 2026 results: net sales $181.5B (+17%), operating income $23.9B (+30%); AWS +28% to $37.6B — its fastest growth in 15 quarters.
Secured multi-gigawatt Trainium commitments — ~2 GW from OpenAI (ramping 2027) and up to 5 GW from Anthropic; custom-silicon run-rate topped $20B.
Guided Q2 2026 net sales to $194–199B (+16–19%) with operating income $20–24B; trailing free cash flow fell to $1.2B as AI capex ramped.
Investor Takeaway
This business shows how a company can turn low-margin distribution into a moat when a high-margin platform sits on top of it. The lesson is that ecosystem design matters as much as product economics when one customer base can be monetized multiple times.
