Trader Joe’s and Aldi are pulling ahead in the battle for grocery market share, according to new retail foot traffic data.
Both chains are not only seeing more shoppers but also fewer customers visiting other stores during the same trip, according to a new report from Placer.ai, a retail analytics firm.
Fewer Shoppers Split Their Grocery Trips
In 2024, just 5% of Trader Joe’s shoppers visited another grocery store immediately before or after shopping at the chain—a slight drop from the previous year. Aldi saw an even larger drop, from 6% in 2023 to 5% in 2024.
This trend suggests that more Americans now treat Trader Joe’s and Aldi as standalone grocery destinations, despite both chains offering a smaller product selection than traditional supermarkets.
Foot Traffic Is Up Across the Board
The report also shows strong foot traffic growth:
- Aldi visits jumped more than 18% year over year in 2024
- Trader Joe’s visits increased by 6% over the same period
- Both chains also saw more visits per location, even if the pace was slightly slower
The momentum has carried into 2025. For the week of February 18:
- Trader Joe’s brought in 6% more shoppers than the same week last year
- Aldi’s visits rose by over 9%
Why Customers Are Staying Loyal
Placer.ai says the shift reflects a growing trust in both brands as primary grocery stops, especially for budget-conscious consumers. With rising food prices, many shoppers are drawn to the value-driven, limited-assortment model that both stores are known for.
Both chains are also becoming weekend shopping hubs. The data shows that Trader Joe’s and Aldi attract a higher share of weekend traffic than their competitors, signaling that customers are using these stores for weekly stock-up trips.
Expansion Plans Are Accelerating
Aldi is capitalizing on this momentum. In February, the company announced plans to open 225 new U.S. stores in 2025, its fastest-ever expansion in the country.
Trader Joe’s is also growing, with 12 new store locations in development as of January 2025.
The Bottom Line
Trader Joe’s and Aldi are tightening their hold on American grocery shoppers. As both chains grow their store footprints and drive more loyal, single-destination traffic, they are reshaping how—and where—Americans shop for groceries.
With fewer shoppers splitting trips and foot traffic rising, these two retailers are fast becoming the go-to choices for value, convenience, and weekend stock-ups.
