Intermarché, Mercadona, and Lidl UK are the retailers that gained the most market share in 2025 compared to the previous year, according to an analysis by NielsenIQ. The study, focused on the five largest European markets, Germany, France, the United Kingdom, Italy, and Spain, identifies the fifteen food retailers with the strongest growth.

Alongside Mercadona, three other Spanish retailers appear in the top fifteen. Lidl España ranks fifth, followed by Consum in twelfth place and Aldi España in fourteenth.

The ranking also includes four French operators, Intermarché, Système U, Action, and Auchan, four from the United Kingdom, Lidl UK, Tesco, Marks and Spencer, and Sainsbury’s, two from Italy, Selex and Lidl Italia, and one from Germany, Rossmann.

Lidl and Aldi continue to have a strong presence in the ranking. Even in a time of inflation control, their price-driven models remain a priority for consumers, says Daniel Ducrocq, vice president of Retail for Western Europe at NielsenIQ.

In France, Ducrocq notes that most of the market share gains come from purchases, but for Intermarché and Coopérative U, the increase is driven by the strong performance of private label. He also points out that market concentration is accelerating, with 79 per cent of fast-moving consumer goods sales concentrated in the five leading retailers in the country.

Finally, Ducrocq highlights that Mercadona, Tesco, and Marks and Spencer are well known for their private label strategies, so their market share gains confirm the strength of this approach.
