Why I Think Walmart’s Real Product Is the Customer
Investors have become fascinated by Walmart’s advertising business. Every earnings season seems to produce another discussion about retail media, digital ads and whether Walmart Connect can become the next great profit engine.
I think the market is staring at the wrong shelf.
Advertising matters, but it is merely one expression of a much larger advantage. Walmart’s true asset is its ability to earn multiple streams of income from a single customer interaction. A family that enters a store to buy milk can also become a marketplace customer, a Walmart+ subscriber, a delivery user and an advertising target, all before the trolley reaches the car park.
The shopping trolley is quietly becoming a multi-product platform.
One trolley. Several businesses. One customer
The Supermarket That Behaves Like Infrastructure
Retail has traditionally been a brutally simple business. More sales require more stores, more staff, more inventory and more capital.
Walmart is quietly changing those economics.
Revenue increased from $572.8 billion in fiscal 2022 to $713.2 billion in fiscal 2026. On the surface, that growth is respectable rather than spectacular. Plenty of investors stop reading at that point and conclude that Walmart remains a mature retailer.
The deeper numbers tell a different story.
Net income climbed from $13.9 billion to $22.3 billion. Operating cash flow rose from $24.2 billion to $41.6 billion. EBITDA expanded from $36.6 billion to $44.0 billion.
The crucial point is that profit growth has materially exceeded revenue growth.
Walmart is not merely selling more goods. It is extracting more earnings from infrastructure that largely already exists.
Its stores are no longer simply stores. They are fulfilment centres, advertising platforms, distribution hubs and membership acquisition engines.
The frozen food aisle has become an asset that works several jobs at once.
Margins Tell Only Half the Story
One reason investors may be underestimating $Wal-Mart(WMT)$ is that the operating margin still looks uninspiring.
Operating margins remain around 4%, while gross margins have stayed remarkably consistent near 25%. These are not the figures normally associated with businesses receiving premium valuations.
Yet net profit margins improved from 2.4% to 3.1%.
A 70-basis-point improvement may appear trivial until one remembers that Walmart now generates more than $700 billion in annual revenue. Tiny improvements on enormous numbers become very large sums of money.
Net income increased by roughly 60% over four years.
This is why I believe investors focusing solely on margins are missing the bigger story.
The more important development is capital efficiency.
The Quiet Revolution in Capital Efficiency
Walmart’s asset base expanded from approximately $245 billion to $285 billion between fiscal 2022 and fiscal 2026.
At first glance, that appears to support the traditional retail model of spending more capital to produce more growth.
However, operating cash flow tells a different story.
Cash generation accelerated far faster than the asset base. Free cash flow approached $15 billion despite capital expenditure exceeding $26 billion during fiscal 2026.
Many of Walmart’s newer revenue streams require relatively little additional investment.
Marketplace sellers use infrastructure that already exists.
Advertisers use data that has already been collected.
Members use delivery networks that have already been built.
Every additional participant increases earnings without requiring another store to appear beside a motorway exit.
Software companies call this operating leverage.
Retailers usually call it impossible.
Two Things Investors May Be Missing
The first overlooked factor is inventory productivity.
Inventory increased only modestly while sales rose by more than $140 billion. For a retailer of Walmart’s scale, maintaining such efficiency during inflationary pressures and supply-chain disruption is quietly impressive.
The second factor is the declining share count.
Diluted shares outstanding fell from approximately 8.4 billion to 8.0 billion. Share repurchases rarely generate headlines because they lack the glamour of artificial intelligence or cloud computing announcements.
Yet fewer shares have amplified earnings growth.
Sometimes the most effective financial engineering involves nothing more exciting than buying your own company.
The Competitive Aisle
Amazon remains the obvious comparison.
$Amazon.com(AMZN)$ possesses stronger advertising economics, vastly superior cloud profits and significantly higher margins. $Wal-Mart(WMT)$ cannot compete directly with Amazon Web Services, nor is its advertising business likely to match Amazon’s scale.
However, Amazon increasingly needs physical infrastructure, while Walmart increasingly monetises physical infrastructure that already exists.
The two companies are approaching one another from opposite directions.
$Costco(COST)$ generates extraordinary loyalty through memberships, but its model relies heavily on annual fees. Walmart benefits from something arguably stronger: weekly necessity-based engagement.
People may postpone buying furniture or electronics, but they remain stubbornly committed to eating dinner.
Target offers superior merchandising and a more curated shopping experience, yet lacks Walmart’s logistical scale and grocery dominance.
There is also an international dimension that receives surprisingly little attention. International revenue now exceeds $130 billion, and several overseas markets continue growing faster than the core US business. If Walmart can replicate its marketplace, advertising and membership ecosystems internationally, the company may eventually export not simply stores, but monetisation systems. Few retailers possess either the scale or customer reach to attempt this.
What makes Walmart unusual is the combination of defence and growth.
Its grocery operations provide resilience.
Its marketplace, membership and advertising businesses provide incremental returns.
Very few companies possess both.
The market trends upward long before the narrative catches up
Where This Thesis Could Be Wrong
The obvious objection is valuation.
Walmart now trades at a multiple that would once have seemed extraordinary for a supermarket operator. Investors are increasingly paying for future monetisation opportunities rather than the existing retail business.
If advertising growth slows, if marketplace expansion disappoints, or if Walmart+ adoption plateaus, the market could begin treating $Wal-Mart(WMT)$ as a conventional retailer again.
There is also the uncomfortable comparison with Amazon.
Amazon’s advertising business remains considerably larger, its technology capabilities are deeper and its profitability is stronger. If retail media eventually consolidates around a handful of dominant players, Walmart may discover that investors have overestimated the size of its opportunity.
The danger is not that Walmart fails operationally.
The danger is that expectations rise faster than earnings.
The market has already paid for part of the story
That risk deserves acknowledgement.
The Debate Investors Should Actually Have
The market frequently asks whether Walmart deserves a technology valuation.
I think that question misses the point.
Walmart will always remain a retailer. The grocery business carries structural limitations that no amount of digital advertising can remove.
The more important question is whether Walmart is becoming the first retailer capable of generating software-like incremental returns while retaining the resilience of a grocery-led business.
That combination is exceptionally rare.
Defensive retail meets platform economics. Few businesses live here
Technology companies often enjoy extraordinary economics but suffer cyclical demand. Grocery retailers enjoy stability but rarely generate exceptional returns. Walmart increasingly appears to sit between those two worlds.
It is building platform economics on top of essential spending.
If that continues, investors may eventually realise that Walmart's greatest competitive advantage is not its stores, its warehouses or even its advertising business.
It is the ability to generate multiple streams of earnings from the same customer relationship while preserving the defensive qualities of a business people rely upon every week.
Finding a company that combines platform economics with everyday necessity remains remarkably uncommon.
That rarity may ultimately prove to be Walmart's most valuable asset.
