The Federal Trade Commission’s decision to block the proposed merger between Kroger and Albertsons was one of the most consequential rulings in U.S. retail history. But what if the deal had gone ahead? How would the combined entity have reshaped the supermarket landscape—and could it have challenged Walmart’s dominance in groceries?
Scale and Market Power
Had the merger been approved, the new company would have become the second-largest supermarket operator in the United States, with nearly 5,000 stores across more than 40 states. The merged chain would have controlled close to 20% of national grocery spending, putting it in direct competition with Walmart, which currently holds just over 20%.
This scale would have given Kroger–Albertsons unprecedented leverage over suppliers, allowing the combined entity to negotiate better terms and reduce costs across categories. In theory, this could have translated into lower shelf prices for consumers and a stronger ability to withstand inflationary pressures.
Competitive Dynamics with Walmart
Walmart’s strength lies in its scale, distribution network, and aggressive pricing strategy. However, a Kroger–Albertsons merger would have brought together two complementary forces: Kroger’s advanced digital ecosystem and loyalty programme, and Albertsons’ strong regional presence in markets where Kroger was weaker.
Together, the merged entity could have mounted a more direct challenge to Walmart’s grocery supremacy. While Walmart dominates in suburban and rural areas, Kroger–Albertsons would have wielded power in urban and regional markets, where its store footprint and brand familiarity run deep.
The battle for shoppers would not only have been about price but also about convenience, product variety, and digital engagement. A larger Kroger–Albertsons could have accelerated investment in e-commerce, same-day delivery, and private-label development, narrowing Walmart’s advantage.
Consumer Impact
For shoppers, the outcome would have been mixed. On the one hand, the combined buying power of Kroger and Albertsons might have driven down costs and expanded the reach of value-driven private-label products. On the other hand, critics warned that reduced competition in certain markets could have led to store closures, higher prices, and fewer choices for consumers—especially in regions where Kroger and Albertsons overlapped heavily.
Supplier and Manufacturer Pressure
For food manufacturers, the merger would have been a double-edged sword. While the new entity would have provided a massive distribution channel, suppliers would likely have faced tougher negotiations and squeezed margins. Smaller brands, in particular, might have struggled to gain shelf space as the retailer consolidated its assortments to maximise efficiency.
Walmart’s Countermove
If faced with a newly merged rival of near-equal size, Walmart would almost certainly have doubled down on its key strengths: operational efficiency, omnichannel leadership, and aggressive price positioning. The retailer has the resources to absorb short-term margin hits to maintain its price leadership—a strategy that has proven effective during inflationary cycles.
Walmart might also have escalated its investment in fresh food, private-label expansion, and health-and-wellness services to differentiate itself further. In a scenario where Kroger–Albertsons challenged its share, Walmart’s sheer financial firepower would still have given it the edge in sustaining long-term market dominance.
A Missed Rivalry
Had the merger gone ahead, U.S. grocery retail would have been reshaped into a two-horse race. Walmart would have faced its first true national challenger in decades, while regional players like Publix, H-E-B, and Aldi would have been forced to carve out niche strategies to stay competitive.
Instead, with the FTC blocking the deal, Walmart retains its commanding lead, and the U.S. market remains fragmented outside of its dominance. The “what if” of Kroger–Albertsons serves as a reminder of how consolidation could have shifted balance—but also how regulatory intervention continues to shape the future of American supermarkets.
