Walmart's 70% Margin Signal: Why the Consumer Trade Is Becoming an Advertising Business
Walmart's headline comp is cooling, but its high-margin ad business may be the real consumer signal heading into earnings.
Walmart is about to offer investors a familiar kind of earnings suspense: a giant retailer whose sales engine is still running, but no longer accelerating at the pace the market has come to expect. U.S. same-store sales growth slowed to 4.1% in the quarter ended April 30, from roughly 4.5% in each of the previous five quarters, and analysts expect the figure to slip below 4% for the quarter ended July 31. The contrarian signal is elsewhere. Walmart Connect, the retailer's advertising business, is growing fast enough and carrying margins high enough to change what a consumer trade actually means.
That distinction matters because Walmart's headline numbers are increasingly being asked to answer two different questions. The first is whether American households are still able and willing to spend. The second is whether Walmart can turn its scale, shopping data and digital reach into a profit stream that is less exposed to traffic, promotions and the cost of moving physical goods. The first answer is getting less comfortable. The second is becoming more important.
The margin hiding behind the aisles
Reuters reported on Aug. 18 that Walmart lowered prices on roughly 7,000 items as shoppers searched for cheaper groceries and essentials. That is a useful snapshot of the operating environment: the retailer is defending value at the same time that investors are asking it to protect profitability. In the Reuters report, Walmart shares were up 2.6% for the year at $114.33, lagging the S&P 500's 13% gain. The market is not treating a 4% comp as a victory by itself. It wants proof that the company's profit mix can improve even as the price-and-volume trade becomes harder.
Walmart Connect is that proof point, at least in theory. The business grew 44% in the quarter ended April 30, its fastest reported pace since Walmart began disclosing the figure in the first quarter of 2023. It was launched in 2019 and rebranded in 2021, and it remains a small fraction of Walmart's $713 billion in annual sales. Yet Reuters reported that its margins contribute about one-third of Walmart's operating income, while analysts estimate gross margins of around 70%. Those figures make the advertising unit more than a side business. They make it a potential answer to the low-margin economics of retail.
Sarah Henry, managing partner at Walmart shareholder Logan Capital Management, told Reuters on Aug. 18 that “The sky's the limit” for how lucrative Walmart Connect can become. That is an optimistic formulation, but it captures the strategic asymmetry. A dollar of advertising revenue does not need a truck, a stockroom or a new store in the way a dollar of merchandise sales does. It can be sold against inventory that Walmart already has, using purchase histories that the retailer already owns. The value is not simply in selling another product. It is in selling better information about the people who buy products.
Morningstar analyst Brett Husslein made the comparison even more directly in the same Reuters report: “They're building it up to the point where it starts to look a bit more akin to Amazon.” The important word is not Amazon. It is “building.” Walmart is still in the investment and proof phase, where advertisers need to be convinced that its data can target customers and then show that an ad produced a purchase. The prize is a retail-media network with a higher-margin, recurring contribution that changes the market's view of Walmart from a scale grocer to a measurement platform attached to a scale grocer.
A consumer slowdown that is also a mix shift
The near-term backdrop is not benign. CNBC reported on Aug. 18 that U.S. retail sales fell in July for the first time in nine months. LSEG expected the U.S. Retail and Restaurant second-quarter earnings index to grow 67% from a year earlier, but the resilience was becoming concentrated: its broadline retail sector, covering 185 retailers, was expected to post 231% earnings growth. That combination of strong aggregate profit growth and uneven household demand is exactly the environment in which high-margin ancillary businesses become decisive.
Jharonne Martis, LSEG's director of consumer research, wrote in a report cited by CNBC on Aug. 18 that “Strong profit growth is being driven by a handful of large, high-margin retailers, while guidance across the broader sector points to a more cautious outlook for discretionary spending in the second half of the year.” Her formulation is a warning against reading the earnings season as a clean consumer rebound. It also helps explain why Walmart's advertising business matters. If discretionary volume is fragile, Walmart can still monetize the attention of a large customer base, the intent behind search and the conversion data generated after a purchase.
Walmart is already showing signs that this digital layer is expanding beyond simple sponsored listings. Reuters said Walmart Connect impressions rose 17% in the second quarter, compared with 9% for Amazon's advertising business, according to Sensor Tower. The retailer's Sparky shopping assistant more than doubled its active users in the quarter ended April 30, according to a May Walmart statement. Nearly one-third of consumer searches now originate on AI models, Flywheel told Reuters, which gives Walmart another reason to treat search, product discovery and advertising as a single strategic surface rather than separate departments.
This is where the bullish and bearish interpretations of the same earnings report can diverge. A bear sees slower comps, price reductions and a premium multiple as evidence that Walmart has little room for error. An optimist sees grocery market share, membership, digital traffic and advertising as a flywheel that can keep comp growth respectable while lifting the quality of earnings. Both can be right in the same quarter. A retailer can be winning share from weaker competitors while the consumer is becoming more price-sensitive, and it can be growing ads while the core basket becomes more promotional.
Wall Street's setup leaves little room for a merely adequate result. CNBC reported that analysts expected Walmart to earn 74 cents a share on revenue of $186.62 billion, compared with company guidance of 72 cents to 74 cents. The stock was up less than 3% for the year, while FactSet data showed about 21% upside to the average price target. On Aug. 4, Oppenheimer analyst Rupesh Parikh downgraded Walmart to perform from outperform and removed a $140 target, pointing to a valuation of about 37 times forward earnings versus a historical level closer to 23 times. He flagged the risk of U.S. comp growth slowing from above 4% into a 2.5% to 3.5% range.
That valuation makes the advertising margin story necessary, but not sufficient. At 70% gross margins, Walmart Connect can make a meaningful contribution without becoming a large share of total sales. But the market will eventually demand evidence that the growth is durable, that advertisers renew campaigns, that measurement remains credible and that Walmart can increase monetization without damaging the value proposition that brings shoppers through the door. Advertising is attractive precisely because it monetizes attention. It becomes dangerous when the pursuit of attention starts to distort price, assortment or trust.
The comparison with Amazon also sets a useful limit. Walmart Connect's impressions may be growing faster from a smaller base, but Amazon has had years to build its advertising tools, demand relationships and reporting infrastructure. Walmart's advantage is different: grocery frequency, a broad physical footprint and a customer base that gives its first-party data a strong link to actual household purchases. Its challenge is proving that advertisers will pay for that link at scale, not just for the reach of the Walmart name.
There is also a macro implication. Retail media turns a consumer slowdown into a more complicated signal for equity investors. If households trade down, Walmart can gain traffic and share. If they reduce discretionary purchases, the retailer can still sell access to high-intent shoppers. If inflation forces more promotions, the company may defend volume while sacrificing merchandise margin. The advertising unit can cushion that pressure, but it cannot repeal it. Investors should therefore watch the mix of sales, gross profit and advertising growth rather than treating the comp number as a standalone verdict on the consumer.
Our view is that the market is looking at Walmart through an outdated aisle-by-aisle lens. The more useful question is whether the company can convert retail scale into a portfolio of monetizable signals without compromising its value promise. For Thursday's report, the high-signal items are not only the U.S. comp and the revenue beat. Watch Walmart Connect growth, its contribution to operating income, evidence of repeat advertiser demand and any sign that digital discovery is moving from a feature into a habit.
If Walmart delivers a solid comp but weak advertising commentary, the stock's premium multiple will look exposed. If the comp softens while Connect continues to grow at a high rate and management shows that the margin contribution is broadening, the market may decide that the slowdown is a mix shift rather than a broken model. That is the contrarian trade: the consumer is not suddenly stronger than the headline data suggest, but Walmart may be becoming more profitable in the exact environment that makes the headline data look weaker.
