Competitive Landscape — Walmart, Costco, Aldi, and the Margin Squeeze

Kroger doesn't operate in a vacuum — it competes for share against Walmart (21% market share, more than Kroger and Costco combined), Costco (9.2% and rising), Aldi (2.8% but growing fastest), and Albertsons (the merger partner that got away). Understanding the competitive picture gives every "Why Kroger?", "How would you grow sales?", and "Where do you think the industry is heading?" question real teeth. This is the synthesis module — it ties strategy, technology, culture, and operations together into the question every interviewer is really asking: can you help us win?
