In one breath
Walmart’s filed numbers show net margins climbing steadily, from 1.9% in FY2023 to 3.1% in FY2026, even as the company holds grocery prices low to pull in traffic. The stock is priced at a multiple well above its own decade median, meaning the market is paying for a business that keeps improving faster than history suggests it should. The open question is whether a grocery flywheel built on thin food margins and high-margin advertising can keep widening those margins if tariffs bite into fresh produce costs, as Reuters reported in July 2026.
A decade ago, Walmart was losing
Cast your mind back to 2015. Amazon was eating retail alive, and Walmart’s stock had just suffered its worst single-day drop in 27 years after the company warned investors that profits would fall. The stores felt dated. The website was an afterthought. And grocery, the one category that gets families through the door every week, was growing slowly while nimbler rivals chipped away at the edges.
The pivot came fast and expensive. In August 2016, Walmart agreed to acquire Jet.com for roughly $3.3 billion, the largest e-commerce acquisition in U.S. history at that point. The bet was less about Jet.com itself, which Walmart quietly wound down by May 2020, and more about the engineering talent and digital playbook it bought with the deal. That purchase was the turning point the current numbers trace back to.
Building the flywheel, one grocery run at a time
The logic Walmart has been executing ever since is straightforward: use low grocery prices to generate foot traffic and delivery orders, then sell advertising against that audience and subscription fees on top of it. Groceries are the bait; everything else is the margin.
By June 2024, Walmart’s InHome delivery service reached over 45 million homes across more than 50 markets, a network built on top of the thousands of stores that already serve nearly 70% of the U.S. population. That physical footprint is the moat. A startup cannot replicate it. A pure-play online grocer cannot match the economics of a store that doubles as a warehouse.
The Q1 FY2027 earnings release, filed for the period ended April 30, 2026, shows the flywheel spinning. Walmart’s global advertising business grew 37% in Q1 FY2027, and e-commerce grew at a similarly strong clip in the same quarter. Those are high-margin revenue lines growing on top of a grocery base that is merely holding its own on price. Think of it as a landlord who charges modest rent to fill every unit, then earns real money from the parking garage and the rooftop billboard.
What the filed numbers actually show
Our data, computed from SEC filings, tells a story of slow and steady margin recovery. Net margins bottomed in FY2023, the year supply-chain costs and wage inflation hit hardest, and by FY2026 the annual 10-K shows them at their highest point in the five-year window we track. Revenue grew from well under $600 billion in FY2021 to $706 billion in FY2026.
The most recent quarterly filing, the Q1 FY2027 10-Q, adds texture. Consolidated gross profit rate improved to 24.3%, driven by merchandise mix shifts toward higher-margin categories. Walmart U.S. comparable sales grew 4.1% for the quarter, with grocery contributing meaningfully. Transactions were up 3%, the strongest U.S. transaction growth in six quarters, meaning more households are choosing Walmart more often, not just spending more per trip.
That transaction figure matters. A retailer can inflate comparable sales by raising prices. Growing transactions means the customer count is genuinely rising, which is a harder and more durable achievement.
The grocery share question
Here is where the story gets complicated. Walmart U.S. grocery net sales topped $285 billion for fiscal year 2026, a meaningful increase year-over-year, but that growth rate is slowing from prior periods. Grocery market share had edged down slightly by early 2026, according to data cited by Grocery Dive. Walmart is still the largest grocer in America by a wide margin, but the direction of share is worth watching.
A McKinsey report from June 17, 2026 noted that North American grocery sales growth in 2025 was almost entirely price-driven, with actual unit volumes declining slightly. Consumers are buying roughly the same number of items but paying more for them, and they are cutting impulse purchases while leaning toward private-label brands. That environment actually suits Walmart: its private-label assortment is strong, and its scale lets it absorb cost pressure better than smaller chains.
The tariff risk is the counterweight. Simply Wall St, citing Reuters reporting in July 2026, flagged that new U.S. tariff policies on fresh produce could squeeze margins for large grocers. Walmart has some insulation, Mizuho’s David Bellinger noted tariff refunds and lower diesel prices as near-term tailwinds, but a sustained increase in fresh produce costs would land directly on the grocery gross margin, which is already thin.
Upper-income households: the unexpected guest
One detail buried in the Q1 FY2027 commentary deserves its own moment. Management noted market share gains particularly among upper-income households, a demographic that historically shopped at Whole Foods or specialty grocers. BNN Bloomberg, citing TD Cowen’s Oliver Chen on July 17, 2026, described this shift as Walmart’s diversified revenue mix attracting higher-income consumers who are now price-sensitive in a way they were not three years ago.
This matters for margins. Higher-income shoppers tend to buy more general merchandise alongside groceries, and general merchandise carries better margins than food. If Walmart keeps this cohort, the mix shift that has been quietly lifting gross profit rates could continue even if grocery prices stay flat.
The math versus the mood
The math, meaning what the filed fundamentals justify, shows a business compounding margins upward while growing revenue at a steady mid-single-digit pace annually. The mood, meaning what the market is currently paying, is a price-to-earnings multiple of 41.8 against a decade median of 35.6, placing the stock at the 76th percentile of its own valuation history. The price-to-sales ratio sits at the 89th percentile of its own decade, meaning the market is paying more per dollar of Walmart’s revenue than it has in almost any year in the past ten.
That gap is the story. The business is improving. The stock is priced for that improvement to continue at a pace above historical norms. If the tariff headwinds on fresh produce prove manageable and the advertising flywheel keeps growing, the filed-trend math and the market’s mood may eventually reconcile. If produce costs rise sharply or upper-income shoppers drift back to specialty grocers, the mood would need to come down to meet the math.
Reading the numbers
- Net margin, FY2026: 3.1%. This is what Walmart keeps from each dollar of sales after every cost is paid. Think of a household earning $100,000 a year and saving $3,100 of it. For a retailer operating on grocery economics, moving from 1.9% to 3.1% in three years is a meaningful shift, not a rounding error.
- Comparable sales growth, Q1 FY2027: 4.1%. This measures sales at stores open at least a year, stripping out the effect of new store openings. It is the cleanest read on whether existing customers are spending more. At 4.1%, Walmart is growing faster than general U.S. retail inflation, which means it is taking share somewhere.
- Gross profit rate, Q1 FY2027: 24.3%, up 6 basis points year-over-year. A basis point is one-hundredth of a percentage point. Six basis points sounds tiny, but on nearly $178 billion of quarterly revenue, each basis point is worth roughly $18 million. The direction matters as much as the magnitude: the Q1 FY2027 10-Q shows the consolidated gross profit rate above the prior-year quarter, continuing the upward trend our five-year filing data tracks.
- P/E multiple: 41.8 versus decade median of 35.6. A price-to-earnings multiple is the price tag per dollar of annual profit. A household paying $41.80 for every $1 of annual income a rental property generates is paying a premium over what the same property historically fetched. That premium is justified if income grows faster than history suggests, and it becomes a problem if growth disappoints.
- Advertising revenue growth, Q1 FY2027: 37%. Walmart’s advertising business sells space to brands that want to reach shoppers already in a buying mindset. Growing 37% on top of a $285-billion grocery base is the high-margin engine that makes the thin-margin grocery strategy viable. A grocery store that also runs a profitable media company is a different animal than a grocery store alone.
