Inside the Aisles of Grocery Retail Media

In Q1 2026, Kroger dominated grocery retail media networks (RMNs) with 2.4 billion impressions, outpacing all other measured grocers by more than 2.5 times. Albertsons ranked second at 950 million, followed by Meijer (715 million). While Kroger led in scale, Meijer and Publix showed the fastest growth.

Meijer's impressions in March 2026 were nearly seven times higher than in January 2024, and Publix consistently ran two to three times its baseline. Facebook emerged as the dominant channel across all six grocery RMNs, with Instagram playing a supportive role, highlighting reliance on Meta for reach. Albertsons and Meijer had higher shares of OnSite Display impressions, while Kroger diversified into TikTok and Snapchat.

Top advertisers distributed impressions differently; Kroger captured the largest share for most, but Albertsons led for Unilever (45%) and Meijer for Kraft Heinz (34%). P&G's presence spiked dramatically, with impressions reaching 212 million in Q1 2026, a 930% year-over-year increase, supporting 31 brands. Crest ran the largest campaign with Instagram ads tagged "Available at Kroger," and P&G leveraged the Super Bowl for a multi-brand "Homegating Starts Here" campaign, demonstrating how grocery RMNs can connect brands to cultural moments beyond food.
