Intermarché leads this week's rankings with a double story: the gain in market share for Mousquetaires, detailed in the October 23 article, and the cyberattacks that targeted the chain's stores. Security difficulties weigh on the entire sector, as E.Leclerc is also at the center of discussions about market share and about points of sale affected by recent incidents. Carrefour had to lower its 2026 forecasts and must cope with the repercussions of disruptions across its French network.
Lidl and Auchan drive the rest of the landscape: the former thanks to the wine fairs and brand comparisons tracked this week, the latter through stores hit by disruptions and food performance seen as under scrutiny in October. Système U appears in the results of the compared chains, while Monoprix Maison is feeling the consequences of refrigeration failures that disrupted several stores. Casino continues to appear in wine fair results, and ALDI is gaining visibility in reports on distributors' market shares.
Overall, the week paints a food sector under pressure, where technical and digital incidents are affecting the most visible chains as well as second-tier players. Market share reports and revised forecasts show that the battle for consumers is now being fought as much on operational resilience as on prices.
