Placer.ai reported that Aldi, Trader Joe’s, and Lidl continue to chip away at the market share of their larger, more well-established competitors. According to Placer, the three grocers experienced significant foot traffic growth in the first half of 2025, with Aldi up 7.1% (year over year), Trader Joe’s up 11.9%, and Lidl up 4.9%. The overall grocery market was up 1.5%.
For Aldi, “average visits per location were 1.6% higher than they were in 2024, 17.4% higher than in 2023, and 26.7% higher than in 2022,” according to the report. The study noted that the company is successfully growing its brick-and-mortar footprint while also growing its customer base.
Trader Joe’s has grown to almost 600 locations across the country, and over the last five years, its relative share of visits has also grown. During that same period in California, home to nearly one third of Trader Joe’s locations, the relative share of visits for Safeway, Vons, and Ralph’s has dropped.
Lidl, which operates 187 U.S. locations, is rapidly gaining suburban, wealthy, and older shoppers. However, the discount grocer is opening stores in major cities in an effort to broaden its appeal to a more diverse customer base.
