Money in Motion (Part 3): Walmart (NASDAQ: WMT) — The Retailer That Decided to Become a Tech Company

🏪 Why This One Is Different

Every other company in our nine-part Business Behind the Brand series had something in common: Australian investors were familiar with them. Coca-Cola. Nike. McDonald’s. JPMorgan. These are brands you interact with, invest through, or read about constantly.

Walmart is the exception.

It doesn’t operate in Australia. There are no stores here. No Walmart-branded anything in your supermarket trolley or on your street. For most Australian investors, Walmart sits somewhere between “the American version of Woolworths” and “that massive company from the movie where they destroy small towns.”

That gap in familiarity makes this piece more important, not less. Because Walmart — at roughly US$826 billion in market cap and over $710 billion in annual revenue — is one of the most consequential businesses on earth. And right now, it is in the middle of a transformation that has direct implications for anyone invested in global consumer, tech, or advertising stocks.

Understanding what Walmart is becoming is more useful than knowing what it has been.

📊 The Numbers That Actually Matter

Start with the Q2 FY2027 results (quarter ended 31 July 2026), reported this week.

The revenue number is deceptively boring. 5.9% growth on a base of more than $710 billion is enormous in dollar terms — but you’re not buying Walmart for top-line growth. You’re buying it, if you buy it at all, for what is happening underneath.

The two numbers that matter most are eCommerce (+23%) and advertising (+38%).

Those are not retailer numbers. Those are platform numbers.

📡 Walmart Connect: The Most Underappreciated Revenue Line in US Retail

Here is the insight most investors miss.

When a consumer goods company wants to reach shoppers at the moment they are about to buy — not browsing, not scrolling, but actually in-store or on a shopping app with their wallet open — they pay to be featured. That payment goes to whoever controls the shelf: physical or digital.

For decades, that shelf was owned by supermarkets. The fees were called “slotting fees” and they were an analogue, opaque arrangement that gave retailers a margin supplement but never became a real business.

Amazon changed the model. It built a digital advertising platform on top of its marketplace and turned it into one of the most profitable businesses in the world. Amazon advertising now generates well over $60 billion per year. The margins on that revenue are extraordinary — close to pure profit — because the infrastructure (the website, the logistics, the customers) already exists.

Walmart is replicating this model. Walmart Connect is its retail media network — the platform that lets brands buy sponsored placements, search positions, and display advertising across Walmart’s digital and physical properties.

In Q2 FY2027, Walmart Connect U.S. grew 43% excluding VIZIO. Global advertising rose 38%. The VIZIO acquisition was specifically designed to deepen this business — VIZIO’s SmartCast operating system gives Walmart connected TV advertising inventory that extends the retail media network into the living room.

For context, global advertising revenue reached approximately $6.4 billion in FY2026. That is still a small percentage of total sales, yet it is already a meaningful and high-margin contributor to operating income growth.

This is not a coincidence. It is a deliberate, capital-intensive bet that Walmart can capture a second margin stream — high-margin advertising revenue layered on top of its existing low-margin retail operations.

🆚 The Amazon Comparison (Done Honestly)

It is tempting to draw a straight line from Walmart’s advertising growth to Amazon’s trajectory. The logic is compelling: Amazon built advertising on top of retail, it now generates tens of billions per year, Walmart is doing the same thing, therefore Walmart becomes the next Amazon advertising empire.

The parallel is real. The timeline and scale are not.

Amazon’s advertising business was built on the back of a decade of e-commerce dominance that created a captive audience of hundreds of millions of active shoppers with rich purchase history data. Amazon’s Prime membership flywheel created the loyalty and data density that made its advertising valuable.

Walmart is building the equivalent from a standing start in e-commerce. Its digital reach is growing — 23% global eCommerce growth is genuine — but its data depth, digital-first customer relationships, and self-serve advertiser infrastructure are all still maturing.

The honest read: Walmart’s advertising business will be meaningfully large. It will not be Amazon advertising in five years. But it does not need to be. Even at a fraction of the scale, a well-monetised retail media business materially changes Walmart’s margin profile and therefore its valuation story.

The question for investors is whether the market is pricing that potential correctly at roughly 36.6x earnings — a multiple that already assumes significant execution on the transformation.

🌏 The Aussie Angle: Why Walmart Matters From 10,000 Kilometres Away

Walmart does not have stores in Australia. But it does have influence over your portfolio, your cost of living, and your currency — in ways worth understanding.

Global supply chain: Walmart is arguably the single most powerful entity in global consumer goods supply chains. When Walmart changes its ordering patterns — because of tariffs, demand shifts, or supplier renegotiations — it creates ripple effects across Asian manufacturing, shipping, and commodity markets that eventually land in Australian prices.

Tariff sensitivity: Walmart sources a significant portion of its products from China. US tariff policy directly affects Walmart’s cost base and, by extension, its pricing power and margins. When tariffs go up, Walmart must choose between absorbing the cost (margin hit) or passing it to consumers (inflation). Q2 FY2027 operating income was partly supported by tariff refunds — a tailwind that may not persist.

AUD/USD as a diversifier: Holding WMT as an Australian investor is, in part, a currency position. Walmart generates revenue in USD. If AUD weakens against USD — as it tends to do when global risk appetite falls — your WMT position appreciates in AUD terms before the stock moves at all. Walmart’s defensive earnings profile (people still buy groceries in recessions) makes it a natural place to hold USD exposure without taking on the volatility of a pure tech or growth position.

Platform access: Australian investors can access WMT directly through US shares via platforms like Stake, Superhero, CommSec International, or Interactive Brokers. WMT is listed on NASDAQ. Standard foreign investment withholding considerations on any dividends apply — confirm current ATO guidance with your adviser.

🔮 Transformation in Progress — Verdict Pending

So is Walmart’s transformation real?

The evidence says: partially, and it is early.

The advertising business is genuinely growing and genuinely high-margin. The eCommerce segment is expanding. The VIZIO acquisition is a calculated bet on connected TV retail media that makes strategic sense. The membership business is growing at 17% — a meaningful recurring revenue stream that improves earnings predictability.

What is not yet resolved: whether Walmart can sustain eCommerce growth against Amazon’s moat without continuously subsidising logistics and pricing. Whether Walmart Connect can reach the data density that makes advertising truly premium. Whether the capital being deployed into tech infrastructure will generate returns that justify the current multiple.

Walmart sits in a genuinely interesting position: too large to be a growth stock, too transformed to be purely a value stock. It is a company mid-metamorphosis — and markets rarely price those well, either over- or under-valuing the endpoint.

The thesis here is not “buy Walmart because it is the next Amazon.” The thesis is “Walmart is building a second business inside a first one, and if that second business reaches even a fraction of Amazon’s advertising scale, the earnings profile changes significantly.” That is a patient investor’s proposition — not a momentum trade.

Whether the market gives you the time to be right is a separate question.

🏁 Nine Companies, One Framework

This is the final piece of a nine-part series. It is worth pausing to say what these nine businesses have in common — and what they reveal about how the US economy actually works.

• Visa: a toll road on every transaction, invisible and indispensable.
• McDonald’s: a real estate company that happens to sell hamburgers.
• Costco: a membership business that happens to sell products at cost.
• Coca-Cola: a brand and distribution network with a product almost as an afterthought.
• Johnson & Johnson: a dividend machine built on healthcare system dependency.
• Berkshire Hathaway: an insurance float that funds a portfolio of entire businesses.
• JPMorgan Chase: the plumbing that moves capital through everything else on this list.
• Nike: a brand licensing operation that happens to make athletic gear.
• Walmart: a retail network building a tech company inside itself.

None of these are what they appear to be on the surface. Every one of them has a business model that runs underneath the obvious product — a structural advantage that compounds quietly while the product gets the attention.

That is the pattern. And it matters more than price momentum, earnings surprises, or analyst upgrades.

The gap between what Aussie investors think they know about US markets and what is actually true is wide. It costs real money over time — in missed positions, in misunderstood risks, in portfolio construction that tracks headlines instead of business models.

That gap is what this publication exists to close.
