On Thursday morning the largest retailer on earth reported a quarter that, on paper, did almost everything right. Revenue of $187.9 billion beat the roughly $186.8 billion consensus. Adjusted earnings came in at $0.81 a share against expectations near $0.74. Operating income rose 28.8 percent, close to five times the pace of sales. Gross margin expanded 158 basis points to 29.4 percent. And full-year guidance went up rather than down: constant-currency sales growth from a range of 3.5 to 4.5 percent to a range of 4.0 to 5.0 percent, adjusted earnings per share from $2.75–$2.85 to $2.80–$2.87.
Hours later Walmart closed down 9.8 percent, from roughly $114.30 to $103.84. It was the company’s worst session since 17 May 2022 — more than four years — and it wiped out close to a tenth of a market capitalisation that had been approaching $900 billion.
The trigger was a single percentage. And a large part of that percentage was not produced in any store. It was produced in Washington.
The number that did it
Walmart U.S. comparable sales — the revenue of stores open at least a year, excluding fuel — grew 2.6 percent. Depending on which survey you read, the street wanted somewhere between 3.5 and 3.8 percent. A year earlier the figure had been 4.6 percent. It is the slowest pace in about six years and the first genuine miss on this line in roughly five.
For an American retail investor, comps are the metric. They are designed to strip out the effect of new square footage and are therefore treated as the most honest available signal of whether a retailer is selling more to the customers it already has. In Walmart’s case the number carries an extra macroeconomic load. Roughly nine in ten Americans live within ten miles of a store, and the grocery aisles skew heavily toward lower-income households, so economists routinely read the quarter as a consumer barometer. When the number prints at a six-year low, the reflex is immediate: the American consumer has run out of road.
This quarter, that reflex is wrong — not entirely, but wrong by the margin that actually mattered to the share price.
Comparable sales are a nominal measure
The error is baked into the construction of the metric. Comparable sales measure revenue, not units. They are transactions multiplied by average ticket, and average ticket is itself units multiplied by price. Cut the price and the metric falls mechanically, even if the identical customer walks out with the identical basket. For the household that is a gain. For the number the equity market reacts to, it is a loss.
Which is why the two components Walmart discloses matter more than the headline. Transactions excluding fuel rose 1.5 percent. Average ticket excluding fuel rose 1.1 percent. Both are positive. More people came, and on average they took more home. The company’s own presentation states plainly that the 2.6 percent was driven by increased customer transactions and unit volumes, partially offset by the pharmacy headwind. Nothing in either component looks like a buyers’ strike.
125 basis points from Washington
The deduction came from the pharmacy counter. On 1 January 2026 the negotiated ceilings on the first tranche of drugs under the Medicare Drug Price Negotiation Program took effect — what the statute calls the maximum fair price. It is, in plain terms, a government-set price cap on a group of high-volume medicines.
Chief Financial Officer John David Rainey put the effect on Walmart U.S. comparable sales at roughly 125 basis points. In the earnings deck that figure sits directly beside the note that prescription counts grew mid-single digits. In the Sam’s Club health and wellness assortment the company measured the pure deflation impact at roughly 900 basis points. More people left the pharmacy holding their medication, and the register still rang up less.
Add those 125 basis points back and comparable sales land near 3.85 percent — above what the street had asked for. Some analysts run it more conservatively, sizing the pharmacy drag at 80 to 90 basis points, which implies something closer to 3.4 or 3.5 percent. That is still inside the range of expectations. On either arithmetic, the miss that cost nearly ten percent of the equity value very nearly disappears.
A second, related effect runs alongside it. GLP-1 weight-loss and diabetes drugs contributed roughly 100 basis points of tailwind to comparable sales in each of fiscal 2025 and fiscal 2026. For the current year Walmart expects about half that, and Rainey was explicit about why: script growth is more than offset by price and mix headwinds. Again, volumes up, revenue per unit down.
The control experiment: the same government inflated the profit
Anyone stripping government action out of the revenue line has to do the same on the profit line — where the state pushed in the opposite direction. On 20 February 2026 the Supreme Court held six to three that the International Emergency Economic Powers Act does not authorise the president to impose tariffs. The levies collected under it — the Penn Wharton Budget Model puts the total at $175 billion to $179 billion — have to go back. As of 31 July, according to Customs and Border Protection, roughly $100 billion of the $168 billion collected from some 330,000 importers had been refunded.
Walmart received nearly $2.9 billion of it in the quarter. That is the main reason reported operating income grew 28.8 percent while adjusted constant-currency operating income grew 17.4 percent. At Target, which reported a day earlier, the distortion is starker still: of $4.11 in reported earnings per share, $1.65 came from the tariff refund. Forty percent of the quarter’s profit was a court ruling. Strip it out and Target earned $2.46, up 20 percent — and its comparable sales rose 3.8 percent on 3.6 percent traffic growth, comfortably ahead of Walmart.
That comparison deserves an asterisk of its own. Target beat Walmart on the metric that broke Walmart’s stock in part because Target has almost no pharmacy exposure: it sold its pharmacy and clinic business to CVS Health for about $1.9 billion back in 2015. A divestment made eleven years ago is doing meaningful work in the relative comp figures of 2026.
So the real shape of the quarter is this. Both of Walmart’s headline numbers were distorted by government action, in opposite directions. A price regulation suppressed the top line; a court ruling inflated the bottom line. The market correctly discounted the inflated profit and took the suppressed sales figure at face value. That is the less consistent of the two available responses.
Walmart is cutting its own prices on purpose — 11,000 times
And the company intends to press harder. Walmart has said it will put the entire tariff refund into lower prices. It ran 11,000 rollbacks in the quarter, up from 7,200 in the first quarter and against a normal run rate of roughly 5,000. Chief Executive John Furner, in the job since the start of the year, has framed it openly as buying share: the investment is concentrated in grocery and general merchandise.
For the metric, that means Walmart is deliberately depressing the numerator of its own comp calculation. Every successful price cut that pulls a customer away from a competitor costs comparable sales growth before it delivers any. Rainey pointed to the cleaner read: the core grocery and general merchandise categories have been, in his words, extremely consistent, largely in the 3 to 4 percent range quarter after quarter. That is where the demand signal lives. It is not the headline.
What actually improved
Beneath the comps argument sits a structural shift that barely registered on Thursday. Global eCommerce grew 23 percent and Walmart U.S. eCommerce 24 percent — the tenth consecutive quarter above 20 percent in the U.S., where online now accounts for roughly a quarter of segment sales. Marketplace sales rose more than 50 percent and store-fulfilled delivery 40 percent.
The margin story sits in the two businesses that are no longer retail in any conventional sense. Global advertising grew 38 percent, with Walmart Connect in the U.S. up 43 percent excluding Vizio. Global membership fee income rose 17 percent and the membership and other income line 15.6 percent. These are revenues carrying gross margins a supermarket cannot reach, and they explain most of the 158-basis-point gross margin expansion. Operating cash flow was $19.7 billion, free cash flow $5.5 billion, and trailing twelve-month return on investment 15.4 percent.
Walmart increasingly earns like a platform and is still valued, and reacted to, like a grocer. That is precisely why a retail metric designed in the 1970s moved more market value in one morning than an advertising business compounding at 38 percent.
The case against this reading
The all-clear would be too cheap if it ignored three things. First, transaction growth halved, from roughly 3 percent in the prior quarter to 1.5 percent. That is not a pricing artefact. Fewer trips per customer is a genuine signal that households at the lower end are economising on journeys — and Walmart is more exposed there than any competitor.
Second, average ticket rose only 1.1 percent. In an economy where consumer prices are climbing faster than that, a ticket this weak means customers are trading down inside the assortment: brand to private label, large pack to small. Good for Walmart’s share, poor for branded packaged-goods suppliers — a point already being made about the food manufacturers that depend on its shelves.
Third, the raised guidance is still a disappointment relative to expectations. The midpoint of the new adjusted EPS range is about $2.84 against a consensus nearer $2.90. And the third quarter carries a separate headwind of more than 100 basis points from the timing shift of Flipkart’s Big Billion Days event in India. Anyone hoping the headline number normalises quickly will not get that in November. JPMorgan and Bank of America both stayed with their buy ratings after the drop — which settles nothing, but does show the argument is live.
What it means for European investors — and for Jackson Hole
Investors outside the United States have seen this mechanism before, without the drama. Tesco grew group like-for-like sales 4.3 percent, with UK and Ireland up 4.9 percent, on sales excluding VAT and fuel of £33.05 billion, up 5.1 percent at constant rates. Ahold Delhaize reported €23.2 billion of net sales, up 1.9 percent at constant currency, with comparable growth excluding gasoline of 1.7 percent and European margin improving to 3.9 percent. Carrefour managed 2.1 percent like-for-like in the first half. In every case the same arithmetic applies: euro-area food inflation has fallen from 2.5 percent in December 2025 to 1.6 percent in June 2026, the lowest reading since mid-2021. Less price on the same volume is less revenue growth — with no customer having gone anywhere.
British investors have an even closer parallel to the cause. Branded-medicine pricing in the UK runs through a negotiated voluntary scheme under which manufacturers hand back a share of NHS branded sales above an agreed growth allowance. Volume and revenue in that market have been decoupled by agreement for years, and nobody reads a fall in NHS drug spend as evidence of a weak consumer. American equity investors are less accustomed to administered prices, and they read the same signal as demand weakness.
Which sets up the macro point, and it becomes relevant within a week. On Friday 28 August, Kevin Warsh delivers his first keynote as Federal Reserve chair at Jackson Hole, where this year’s theme is financial innovation and its implications for payments and policy. The funds rate sits at 3.50 to 3.75 percent, and at the July meeting three regional presidents dissented in favour of a hike — the first time three policymakers broke ranks in the same direction since 2016. In that setting there will be a temptation to file a soft Walmart print as evidence of fading price pressure. It would be a category error. What compressed Walmart’s revenue was not slackening demand; it was a statutory ceiling on the price of a handful of medicines. That kind of disinflation genuinely relieves household budgets, tells you nothing about the output gap, and drops out of the data the moment the base effect laps it.
The most useful summary of the quarter came from the chief financial officer, though he did not intend it as one: the core categories keep growing 3 to 4 percent, quarter after quarter, with unusual consistency. That is the state of the American consumer. The 2.6 percent on the headline is the state of a metric that cannot tell a cheaper price from a lost customer.
