Grocery Units Went Negative in June. Walmart Is Still Gaining Share.

American grocery shoppers bought 1.8 percent fewer items in June than a year earlier, according to a Bain & Company analysis of NielsenIQ data published by CNBC on July 16. The same measure grew 0.1 percent in June 2025. Prices are still rising roughly 2 to 3 percent a year, but that inflation cushion is no longer enough to keep total grocery sales growing.

The pressures behind the pullback have been building for months. Grocery prices sit about a third above 2019 levels per federal price data, fuel costs have climbed, and lower-income households have absorbed reduced SNAP benefit amounts and tighter eligibility rules. Bain’s Consumer Pulse survey from May found 80 percent of Americans trying to spend less and 28 percent actively cutting grocery spending. Within that cutting group, 56 percent are trading down to cheaper brands, 49 percent are buying fewer items, and 44 percent are relying more on coupons and promotions. Kurt Grichel, who leads Bain’s Americas retail practice, described a stock-up trip that cost $300 in 2019 now ringing up at $400, a gap large enough that even upper-income shoppers are feeling sticker shock and shopping around.

Circana Measured the Same Half Year and Found Flat, Not Falling

Three days before the Bain data landed, Circana published its own read. Circana’s July 13 Compass research put U.S. retail food and beverage growth at 2.2 percent for the first half of 2026, with volume flat, and the firm expects volume to stay flat through the balance of the year. Price and mix carried the growth, up 2.3 percent, with packaged food up 3.7 percent while fresh rose just 0.4 percent.

The two datasets measure different things, and the difference matters. Circana’s figure is total food and beverage volume averaged across six months. Bain’s figure is grocery units in June specifically. A flat half is fully consistent with a June that broke negative, which is why the June number deserves attention: it may mark the month the average tips. Circana’s behavioral diagnosis also differs in emphasis. Sally Lyons Wyatt, Circana’s global executive vice president and chief advisor, argues consumers are “no longer simply trading down or cutting back” but becoming more intentional through pack-size choices, private label selection, and AI-assisted shopping. Suppliers should read the two reports together rather than choosing one: the shopper is stretching every dollar harder, whether the firms call that retreat or rationalization.

Walmart Is Growing Its Slice of a Pie That Stopped Growing

Walmart’s most recent earnings put the retailer on the winning side of this squeeze. In its first quarter of fiscal 2027, reported May 21, Walmart reported share gains in both grocery and general merchandise, with upper-income households leading the growth. Read alongside the demand data, the connection suggests itself: the sticker-shocked upper-income shopper Grichel describes matches the profile of the customer Walmart reported winning.

Walmart is pressing that position. On July 6 the retailer announced price reductions across thousands of summer items, dropping a one-pound roll of ground beef roughly 12 percent to $5.94 from $6.74, with cuts spanning produce, beverages, and household goods across stores, clubs, and its apps. Julie Barber, executive vice president and chief merchant of Walmart U.S., framed the move in the announcement as another round of price investment aimed at the products customers shop for most during the summer season. The category choices track Grichel’s observation that the pricing edge goes to grocers who are sharp on the items shoppers actually notice, the ground beef, milk, and eggs tier of the basket.

For 1P grocery suppliers, the implication is direct: Walmart is funding visible price cuts while gaining share in a shrinking-unit category, and the pressure to help fund that value position will show up in cost negotiations, rollback participation asks, and promotional planning through the second half. For 3P Marketplace sellers the effect is less direct but real. Grocery value drives the traffic, and price-sensitive shoppers arriving for $5.94 ground beef are the same shoppers browsing consumables and general merchandise listings with sharpened price expectations.

Manufacturers Are Already Paying for the Volume Fight

The supplier side of this equation is visible in PepsiCo’s second quarter, reported July 9. PepsiCo’s North American food volumes were flat despite stepped-up affordability investments, and North America food revenue declined 2 percent. CEO Ramon Laguarta told analysts “the consumer is worse than what we had anticipated,” pointing mainly to gas prices, which hit a four-year national average high of $4.56 per gallon in late May. Executives also pointed to lower effective pricing in the quarter, meaning promotional spend rose as shoppers grew more price sensitive. Management’s second-half plan includes higher North America advertising and marketing spend while refining trade and pricing tactics customer by customer.

That last phrase deserves a supplier’s attention. Trade and pricing decisions made customer by customer are decisions made retailer by retailer, and no customer table is bigger than Walmart’s. Telsey Advisory Group analyst Joe Feldman told CNBC that grocers are pressing suppliers for price reductions where they can find them, that suppliers see the need themselves, and that the entire industry is now chasing growth in units rather than only in dollars.

Suppliers preparing for fall line reviews should expect that shift to reframe the conversation. A plan built on price-driven dollar growth now reads as a plan built on a cushion that stopped working in June. Merchants managing categories with negative units will be looking for the mechanisms PepsiCo is already funding: sharper opening price points, promotional depth on high-velocity items, and pack architectures that give a rationalizing shopper a reason to stay in the brand rather than slide to private label.

None of this arrived without warning. Bain’s January retail outlook projected U.S. retail sales growth slowing to 3.5 percent this year from 4.0 percent, and flagged a flight to value toward lower-priced and private-label goods as the force that could temper growth further. The June unit data suggests that flight has begun, and the second half of 2026 will be measured in units.
