Retail Titans Walmart and Costco Defy Inflation Surge
23 Aug
Summary
- Walmart and Costco expected to benefit as grocery prices rise
- Walmart keeps price increases to 3% vs. 7.5%+ at rivals
- Walmart, Costco stocks climb 66% and 181% in past 5 years

As of August 23, 2025, the retail landscape is being reshaped by rising grocery prices driven by President Trump's tariffs. However, two retail titans, Walmart and Costco, are emerging as inflation-proof powerhouses.
According to a recent analysis, Walmart has managed to keep the increase in grocery prices to just 3% over the past 18 months, a stark contrast to the 7.5% or more seen at rivals like Amazon, Kroger, and Target. Walmart's massive scale and buying power have allowed it to force suppliers to keep prices lower, benefiting its customers.
This resilience has translated to impressive financial results for both companies. In its fiscal year 2024, Walmart grew total revenue by 6% to $648 billion and adjusted earnings per share by 5.7% to $6.65. Over the 52 weeks following that announcement, Walmart's stock price climbed 66%. Costco has also thrived, with its stock up 181% over the past 5 years.
As grocery prices continue to rise, more Americans are expected to turn to Walmart and Costco, known for their emphasis on low prices. The two retailers' ability to weather the inflationary storm has cemented their positions as dominant forces in the retail industry.
