Amazon is not a hidden stock.

Everyone knows the company. Everyone uses the company. Everyone understands that Amazon is more than just online shopping.

But I still think a lot of investors underestimate the actual machine that Amazon has built.

This is not just an e-commerce company, a cloud company, an advertising company, or an AI infrastructure company. It is all of those businesses connected together in one ecosystem.

That is what makes Amazon so powerful.

Amazon has the consumer relationship through Prime. It has the marketplace through third-party sellers. It has the cloud infrastructure through AWS. It has the advertising layer built on purchase intent. It has the fulfillment network. It has subscriptions. It has logistics. It has AI infrastructure. It has data.

Most companies would love to have one of those businesses.

Amazon has all of them.

That is why I own $AMZN.

The Amazon Ecosystem

The easiest mistake with Amazon is trying to value it like one simple business.

Amazon is not simple.

The company reports in three main operating segments: North America, International, and AWS. But underneath that, Amazon has multiple revenue streams: online stores, physical stores, third-party seller services, subscription services, advertising services, AWS, and other revenue.

In 2025, Amazon generated roughly $717 billion in total net sales. AWS alone produced nearly $129 billion. Advertising services generated almost $69 billion. Third-party seller services generated over $170 billion. Subscription services generated nearly $50 billion.

Those numbers matter because they show how diversified Amazon really is.

Amazon is not dependent on one single lever. Retail creates the customer relationship. Third-party sellers create marketplace depth. Prime increases loyalty. Ads monetize purchase intent. AWS monetizes enterprise cloud demand. AI infrastructure expands the AWS opportunity. Logistics improves speed and efficiency.

Each part strengthens another part.

That is the Amazon flywheel.

The more customers use Amazon, the more valuable the marketplace becomes. The more sellers join the marketplace, the more selection improves. Better selection and faster delivery make Prime more valuable. More shopping activity creates more valuable ad inventory. More scale gives Amazon more data, more efficiency, and more negotiating power.

This is not a normal business model.

This is a machine.

Retail Is Still the Foundation

Retail is not the highest-margin part of Amazon, but it is still the foundation of the entire company.

The retail business gives Amazon scale, customer trust, Prime relationships, seller relationships, fulfillment density, and daily consumer relevance.

That matters.

A lot of companies have great apps. Fewer companies have a product people use constantly. Amazon is one of those rare companies that has become part of everyday life.

The retail business also gives Amazon a massive advantage in advertising. When someone searches for a product on Amazon, they are usually much closer to buying than someone scrolling through a social media feed.

That is why Amazon advertising is so valuable.

Retail may not be the flashiest part of the story, but without retail, Amazon does not have the same Prime ecosystem, marketplace power, ad opportunity, or logistics advantage.

The bullish case is not that retail suddenly becomes a software-margin business.

The bullish case is that Amazon keeps making retail more efficient while the higher-margin businesses built on top of retail become a bigger part of the profit mix.

That is where the earnings power can come from.

Third-Party Sellers Are a Huge Part of the Story

One of the most underrated pieces of Amazon is third-party seller services.

Amazon is not just selling products directly. It is also providing infrastructure for millions of sellers.

Sellers use Amazon for access to customers, fulfillment, payments, logistics, advertising, and trust. In return, Amazon collects fees from seller services, fulfillment, and ads.

This is a very important part of the model because it turns Amazon into a platform, not just a retailer.

The more sellers use Amazon, the more selection customers get. The more selection customers get, the more valuable Prime becomes. The more customers shop, the more sellers need Amazon. The more sellers compete, the more valuable Amazon advertising becomes.

That is a powerful loop.

Third-party seller services also help explain why Amazon’s retail business is better than it looks on the surface. The company is not only earning money from direct product sales. It is earning money from the infrastructure behind commerce.

That is a better business than traditional retail.

AWS Is the Profit Engine

AWS is still one of the most important parts of the Amazon thesis.

Cloud infrastructure is one of the most important markets in the world, and AI is only making it more important.

Every company wants to use AI. But to use AI, companies need compute, storage, databases, networking, security, chips, and developer tools.

AWS sits directly in the middle of that.

In Q1 2026, AWS revenue grew 28% year over year to $37.6 billion. That was a major acceleration and showed that AWS is still a serious growth engine even at massive scale.

Even more important, AWS produced $14.2 billion of operating income in the quarter.

That is why AWS matters so much.

Amazon’s retail business creates scale. But AWS creates profit.

This is also why I view Amazon as one of the better AI infrastructure plays in the market. Amazon is not just talking about AI. It is building and selling the infrastructure that companies need to run AI workloads.

AWS has Bedrock, Trainium, Graviton, custom silicon, cloud infrastructure, and a massive enterprise customer base. Amazon is spending aggressively because demand for compute is growing aggressively.

The market may debate whether AI capex is too high in the short term.

That is fair.

But if Amazon is right, this spending can strengthen AWS for the next decade.

Advertising Might Be Amazon’s Best Hidden Profit Lever

Amazon advertising is one of the most attractive businesses inside the company.

The reason is simple: Amazon owns purchase intent.

Google knows what people search for. Meta knows what people engage with. Amazon knows what people are actually trying to buy.

That is incredibly valuable.

If a customer searches for running shoes, protein powder, headphones, or a laptop on Amazon, brands want to show up at that exact moment. That makes Amazon’s ad inventory very different from traditional display ads.

It is closer to the point of purchase.

In Q1 2026, Amazon advertising revenue was about $17.2 billion, up roughly 22% year over year.

That is a massive business by itself.

The other important part is margins. Advertising should be much higher margin than traditional retail. So as advertising becomes a larger part of Amazon’s business mix, it can help overall profitability improve.

This is one of the biggest reasons I am bullish on Amazon long term.

Amazon does not need retail margins to become amazing if AWS and advertising keep becoming larger profit drivers.

The business mix is changing.

That is what matters.

Prime Is the Glue

Prime is one of the most important consumer products in the world.

It is not just free shipping.

Prime is shipping, video, music, deals, convenience, habit, and loyalty. It keeps customers inside the Amazon ecosystem.

That matters because the best businesses are not just the ones that acquire customers. They are the ones that keep customers and expand the relationship over time.

Prime does that.

A Prime member is more likely to shop on Amazon, watch Prime Video, use Amazon devices, see Amazon ads, and stay inside the ecosystem. Prime gives Amazon a recurring relationship with customers instead of needing to win every transaction from scratch.

It also gives Amazon more ways to monetize.

Prime Video can support ads. Prime shopping creates purchase data. Prime delivery reinforces convenience. Prime Day drives volume. The subscription itself creates recurring revenue.

This is why I think Amazon’s ecosystem is so hard to compete with.

Competitors can copy pieces of Amazon.

It is much harder to copy the entire system

The Margin Expansion Story

The biggest reason I like Amazon today is the margin expansion story.

Amazon already has the scale.

The question now is how much profit the company can produce from that scale.

For years, Amazon spent heavily on fulfillment, logistics, AWS, content, international expansion, and new growth areas. That made the company look less profitable than it could eventually become.

Now the business is starting to show more operating leverage.

In Q1 2026, Amazon reported total net sales of $181.5 billion, up 17% year over year. Operating income reached $23.9 billion. That is a massive number.

This is the key point: Amazon’s revenue base is already enormous. Even small improvements in margin can create huge increases in operating income.

That is why I think Amazon can look cheaper than it appears.

A surface-level multiple does not fully capture what happens if AWS keeps growing, advertising keeps scaling, retail efficiency improves, and international losses continue moving in the right direction.

Amazon does not need every segment to be perfect.

It just needs the profit mix to keep improving.

That is the setup I like.

AI Capex Is the Main Debate

The biggest risk in the Amazon thesis right now is capex.

Amazon is spending a massive amount of money on AI infrastructure, data centers, chips, and AWS capacity.

In Q1 2026, free cash flow fell sharply to around $1.2 billion on a trailing twelve-month basis, mainly because of increased property and equipment purchases tied to AI investment.

That is the bear case.

Amazon is generating a lot of operating cash flow, but it is also reinvesting aggressively. If AI demand disappoints, or if returns on capex are lower than expected, investors could get frustrated.

That risk is real.

But I do not automatically view heavy capex as bad.

The question is not whether Amazon is spending a lot. The question is whether that spending earns attractive returns over time.

If AI demand keeps growing, AWS capacity becomes more valuable. If Trainium and Graviton help Amazon lower costs and improve performance, AWS becomes more competitive. If companies keep moving workloads to the cloud, Amazon’s infrastructure advantage becomes even more important.

This is the tradeoff investors have to accept.

Short-term free cash flow may look messy.

Long-term earnings power may be getting stronger.

For me, that is a tradeoff I am willing to study and hold through as long as the demand signals stay strong.

What Could Go Wrong

No stock is risk-free, and Amazon is no exception.

The biggest risk is that AI capex does not produce the returns investors expect. If Amazon keeps spending heavily but AWS growth slows or margins compress, the stock could struggle.

Competition is another risk. AWS competes with Microsoft Azure and Google Cloud. Advertising competes with Google, Meta, TikTok, retail media networks, and others. Retail competes with Walmart, Costco, Target, Temu, Shein, and many more.

Regulation is also a real risk. Amazon is massive, and massive platforms always attract regulatory attention.

Consumer weakness could pressure retail. Cloud optimization could pressure AWS. International markets could remain lower margin. Logistics investments could take longer to pay off.

These risks are real.

But the question is whether the upside is still worth the risk.

For me, the answer is yes.

What I Am Watching

For Amazon, I care about a few key things.

First, AWS growth. If AWS continues accelerating or holding strong growth at scale, that supports the AI infrastructure thesis.

Second, AWS margins. Growth is great, but operating income matters.

Third, advertising growth. This is one of Amazon’s highest-quality revenue streams, and I want to see it keep compounding.

Fourth, retail margin improvement. The stores business does not need huge margins, but efficiency gains can matter a lot because the revenue base is so large.

Fifth, free cash flow after the AI capex cycle. I am okay with heavy investment if returns show up later. But eventually, those investments need to turn into cash flow.

Sixth, Prime engagement. Prime is the glue holding the consumer ecosystem together.

Those are the numbers I care about more than daily stock price movements

Final Thoughts

Amazon is one of the best businesses in the world.

That does not mean the stock goes up every quarter. It does not mean valuation never matters. It does not mean the AI capex risk should be ignored.

But I think the long-term setup is still very strong.

Amazon has multiple ways to grow earnings. AWS can keep scaling. Advertising can become a larger profit driver. Retail can become more efficient. Prime can keep customers locked into the ecosystem. Third-party seller services can keep expanding. AI infrastructure can create another wave of demand.

That is why I own $AMZN.

This is not a simple “Amazon is more than retail” thesis.

Most people already know that.

My thesis is that Amazon’s earnings power is still not fully appreciated.

The company has spent years building the infrastructure, customer relationships, marketplace, cloud platform, ad network, logistics network, and AI capacity.

Now the question is how much profit all of that can produce.

I think the answer could be a lot more than people expect.
