Overview
This lecture explores the rise of Walmart as the largest U.S. grocer, examining how inflation, innovation, and scale have contributed to its dominance, and considering implications for consumers, competitors, and small grocers.
Rising Grocery Prices and Consumer Response
- Food at home prices increased 11.4% in 2022 and are expected to rise 5% in 2023.
- Inflation has driven more Americans, across income levels, to Walmart for lower grocery prices.
- Walmart now receives over 25% of U.S. grocery dollars, up 1.5% from 2021.
- Higher income shoppers now make up about half of Walmart's food market share gains.
Walmart's Growth and Market Strategy
- Walmart is the largest U.S. grocer, with sales more than double its nearest competitor.
- The company improved online shopping, added automation, and expanded delivery options (including drones and in-home delivery).
- Walmart benefits from scale to negotiate lower prices with suppliers.
- Its private label brands, especially Great Value, are highly popular among consumers.

Historical Context and Industry Consolidation
