Cloud Is Carrying the Store
- AWS is the profit engine, with sales up 28% in Q1 2026 and a $150 billion annual run rate.
- Amazon's AI services are now above a $15 billion run rate inside AWS.
- Management says its custom chip effort could be a $50 billion run-rate business if it stood alone.
- The bear case is the huge spending plan, with about $200 billion of 2026 capital spending guided mostly for AWS.
- A $364 billion AWS backlog gives Amazon more proof that customers are lining up for the new capacity.
The cloud bet is working
Amazon still looks like a store from the outside. Most sales come from North America and International retail. But the main profit story is AWS, the cloud unit that rents computing power to companies and governments. In Q1 2026, AWS sales grew 28% year over year and reached a $150 billion annual run rate.
The AI story is now less about hope and more about reported demand. Management said AWS AI revenue is above a $15 billion run rate. It also said the Graviton and Trainium chip effort could be a $50 billion run-rate business if it were a stand-alone company. Bedrock, the service that lets customers use foundation models, also showed fast customer spend growth.
That supports the bull case. Amazon is spending heavily because customers want more cloud and AI capacity. Management said a substantial portion of the planned AWS capital spending already has customer commitments, and AWS backlog stands at $364 billion before adding a new deal of more than $100 billion.
The bear case has not gone away. Amazon guided to about $200 billion of total 2026 capital spending, mostly for AWS. That is a huge check to write. If demand slows, if data centers are delayed, or if the new AI workloads carry lower margins than core AWS, depreciation could pressure profit. The stock also does not look cheap, so investors need both growth and execution to stay strong.
Traffic first, profit second
Amazon runs retail at thin margins on purpose. Low prices, fast shipping, and Prime keep shoppers coming back. That traffic gives Amazon power. Third-party sellers pay fees to reach shoppers, and advertisers pay for sponsored spots near the point of purchase.
AWS works very differently. It sells cloud computing by usage, so customers pay more as they store more data, run more software, or train more AI models. Large customers can leave AWS, but doing so is hard and slow. That makes AWS more durable than a normal product sale.
Advertising is the hidden high-margin layer. Brands pay Amazon because shoppers on Amazon are often ready to buy. This turns the retail store into a large ad platform, not only a place to sell goods.
The weak point is cash. Amazon spent $128.3 billion on cash capital expenditures in 2025 and plans a major step-up in 2026. If the new AWS capacity earns strong returns, the model gets better. If not, free cash flow can shrink fast.
What Amazon sells
AWS
Cloud computing rented by usage. It is Amazon's main profit driver and the home of the AI buildout.
AWS AI services
AI tools such as Bedrock let customers use and build with large models. Management disclosed an AI revenue run rate above $15 billion.
Custom silicon
Graviton and Trainium are Amazon's in-house chips for cloud and AI workloads. Management said the chip effort could equal a $50 billion run-rate business if sold like a stand-alone chip company.
Online stores and Prime
The core shopping site and membership program drive loyalty and order volume. Everyday essentials now make up one-third of units sold in the U.S. store.
Third-party marketplace
Outside sellers pay Amazon for access, payment flow, storage, delivery, and other services. Amazon can earn fees even when it does not own the product.
Advertising
Sponsored listings, display ads, and video ads monetize Amazon's shopping traffic. The business is running at about an $85 billion annual rate.
Project Kuiper
Kuiper is Amazon's low-earth-orbit satellite internet project. It has meaningful revenue commitments before commercial launch, but it is still early.
Sales mix still looks like retail
Mix is from Q1 2026 net sales in Amazon's Form 10-Q. North America and International include retail, marketplace, subscriptions, and advertising, while AWS is reported as its own segment.
What could break the thesis
Capex outruns demand
High impact · Medium oddsAmazon is planning about $200 billion of 2026 capital spending, mostly for AWS. Management says much of the capacity has customer commitments, but the size still demands strong execution. If AI demand cools or data centers arrive late, depreciation can hit margins before revenue catches up.
AI supply chain bottlenecks
High impact · Medium oddsAmazon says it relies on a limited group of suppliers for semiconductors, including GPUs used for AI infrastructure. A shortage of chips, memory, or power can cap growth even when customers want more capacity. This matters because the AWS growth plan depends on installing a lot of new infrastructure.
AWS margins disappoint
High impact · Medium oddsAWS growth has re-accelerated, but the margin profile of newer AI services is still an open question. Training and inference workloads can require expensive chips and power. If AI revenue grows but earns lower returns than core cloud services, the bull case becomes less powerful.
Retail profit gives back gains
Medium impact · Medium oddsNorth America and International retail are still the largest sales base. Better fulfillment efficiency and advertising helped recent results, but shipping costs, tariffs, wages, and a consumer slowdown can pressure margins. A weak retail base would leave AWS carrying even more of the company.
Regulators target the profit pools
Medium impact · Medium oddsAmazon faces investigations and litigation over issues such as monopolization, price fixing, and consumer protection. The risk is not only fines. A remedy that changes marketplace rules could affect seller fees or advertising, two of Amazon's better profit pools.
In one breath
How does Amazon actually make money?
Retail brings the traffic, but it often carries thin margins. The bigger profit engines are AWS cloud computing, advertising, seller fees, fulfillment fees, and Prime subscriptions.
Why does AWS matter so much to Amazon?
AWS is the cloud business that rents computing power to companies and governments. It is smaller than retail by sales, but it produces a large share of operating profit.
What is Amazon's biggest risk right now?
The biggest risk is the capital spending cycle. Amazon is spending about $200 billion in 2026, mostly for AWS, so AI and cloud demand must stay strong enough to earn good returns.
Is Amazon mainly an AI stock now?
AI is now a major part of the AWS growth story, but Amazon is still a mix of retail, cloud, advertising, subscriptions, and marketplace services. The AI upside is real, while the spending risk is also real.
