Trader Joe's store-brand model looks increasingly like a winning strategy

Private labels are no longer the bargain-bin fallback in grocery. In FMI’s 2026 private-brand research, clubs and supermarkets both gained year-over-year share, while mass retailers, dollar stores, and drug stores slipped and convenience stores mostly held steady. For Trader Joe’s, that is less a trend to chase than a confirmation of how the chain already works.

Why the market is tilting toward store brands

The clearest signal in FMI’s data is shopper intent. About 43% of surveyed consumers said they plan to buy private brands somewhat or much more, compared with 27% who said the same for national brands. FMI’s June 16 consumer research also says nine-in-10 shoppers buy store brands, which means the question is no longer whether private label has a place in the basket. The question is which retailers can make that basket feel worth repeating.

Circana’s broader read on the category helps explain the scale. In the United States, private-label sales reached $330 billion in 2025, with a 24% unit share and a 23% dollar share of the total market. PLMA’s 2026 Private Label Report put store-brand sales at a record $282.8 billion in all outlets last year, up by a little more than $9 billion from 2024, and said store brands grew at nearly three times the dollar-sales rate of national brands in 2025. That combination of higher share, stronger growth, and durable shopper penetration shows private label has become a structural part of grocery, not a temporary inflation-era trade-down.

Why Trader Joe’s is already built for this

Trader Joe’s is not trying to retrofit itself into a private-label-heavy business. The company says more than 80% of what it sells is private label, that it does not collect slotting fees, and that its buyers travel the world looking for products that are exceptional and likely to find a following with customers. It also says every product goes through a rigorous tasting panel process before it reaches shelves.

That operating model matters because Trader Joe’s sells store brands the way many chains sell national brands: as the main event. The limited assortment gives crew members a tighter set of products to know well, and it gives customers a clearer reason to trust the recommendation on the shelf talker, at the register, or from a crew member who has actually tasted the item. In a store built around discovery, product knowledge is not a soft skill. It is part of the merchandising.

The rising share of private brand across grocery only sharpens that edge. Trader Joe’s challenge is not proving that store brands can win. It is keeping the lineup fresh enough that customers feel they are discovering something new, not just buying another version of the same value story.

What shoppers are telling retailers they want

FMI’s 2026 consumer materials say the strongest drivers of private-brand growth are quality and taste, not just price. Among shoppers who increased their private-brand purchases, 39% cited quality and 37% cited taste. That is a useful reminder for Trader Joe’s crew and managers: the chain’s private-label promise depends on more than low everyday pricing.

Customers come back when the product earns trust in the pantry and in the fridge. A good store-brand model has to clear three hurdles at once: it has to feel distinct, it has to taste good enough to replace a familiar national brand, and it has to be easy for crew to explain without sounding scripted. Trader Joe’s already leans into that formula by making curation part of the brand itself. The buying team’s role is to source and test products that feel special, and the store team’s role is to translate that into a quick, credible recommendation.

That is where everyday store pride becomes operational. When a crew member knows why a snack, sauce, frozen meal, or beverage is on the shelf and what makes it different, the store does more than move units. It builds the kind of customer trust that makes a private-label-heavy assortment feel like a service rather than a compromise.

What the data means for crew and managers

The current market is rewarding retailers that can make their own brands feel like the smart choice. Clubs and supermarkets are taking share, while mass retailers, dollar stores, and drug stores are losing ground in private-brand unit and sales share. For Trader Joe’s, that reinforces the logic of a model that keeps the assortment tight, the products distinctive, and the conversation around the products active on the floor.

For crew, the practical takeaway is straightforward:

• Know the backstory on the items customers ask about most.
• Be ready to explain taste, use, and why a product is on the shelf.
• Treat tasting panels, product feedback, and customer reactions as part of the job, not background noise.
• Use the store’s limited assortment as an advantage, since it lets you know the products better than a typical grocer can.

For managers, the message is equally clear. The model works when the store keeps feeding the buying side with real feedback and keeps the floor team fluent in the assortment. Private-brand growth can make a retailer look strong on paper, but Trader Joe’s depends on a more specific standard: customers have to believe that the chain’s own label is chosen with intent, tested with care, and worth seeking out again.

That is why the numbers matter. A category that already reaches $330 billion in U.S. sales, with nine-in-10 shoppers buying store brands, is not a niche. It is the terrain Trader Joe’s has been playing on for years. The stores that will keep winning are the ones where the label on the package and the knowledge on the floor feel like the same promise.
