The retail sector often serves as a refuge for investors during economic downturns, and Walmart (WMT) and Costco (COST) have proven themselves resilient in turbulent times. Both companies have unique strengths: Walmart dominates with its scale and competitive pricing, while Costco thrives on its membership-driven model and bulk discounts. But as their stocks continue to outperform the market, which one offers the better opportunity for investors today?
Walmart’s Wide Reach and Diversified Operations
Walmart is a global powerhouse. With over 10,600 stores spanning the U.S., Mexico, China, and other markets, the retailer commands unparalleled reach. Its business includes traditional superstores and the Sam’s Club brand, which competes directly with Costco in the warehouse club segment.
Despite its global footprint, Walmart derives more than 80% of its revenue from its U.S. stores. Its ability to integrate brick-and-mortar and e-commerce operations is a significant advantage. For instance, Walmart’s online order fulfillment leverages its extensive physical locations, giving it an edge over pure e-commerce players.
In fiscal 2024, Walmart’s revenue grew 6%, driven by strong U.S. comparable sales (up 5.6%) and a 13% rise in international revenue. Although its store count has declined slightly due to divestitures, the retailer has focused on automation and subscription services like Walmart+ to stay competitive. Looking ahead, analysts predict a compound annual growth rate (CAGR) of 5% in revenue and 17% in earnings per share (EPS) through 2027.
Costco’s Membership Model and Steady Growth
Costco operates 897 warehouses globally, with a majority located in the U.S. Its business hinges on membership fees, which contribute significantly to its profits. This model enables Costco to sell products at minimal margins while relying on recurring membership revenue.
The retailer has consistently grown its membership base, reaching 138.8 million cardholders in fiscal 2025, with a high renewal rate of 90.4%. Recent fee increases, the first in seven years, demonstrate its pricing power and ability to weather inflationary pressures.
While Costco’s pandemic-driven growth has moderated, it continues to post strong numbers. Revenue rose 5% in fiscal 2024, with e-commerce sales surging by 16%. Analysts anticipate a CAGR of 7% in revenue and 11% in EPS through 2027.
Comparing Financial Metrics and Valuation
Both Walmart and Costco have delivered impressive stock performance over the past three years, with returns of over 90% and 60%, respectively. This far outpaces the S&P 500’s 23% gain during the same period.
However, their valuations tell different stories. Walmart trades at 34 times forward earnings, while Costco’s multiple stands at a loftier 47. Both stocks also offer low dividend yields—0.91% for Walmart and 0.49% for Costco—making them less attractive for income-focused investors in a high-interest-rate environment.
Here’s a snapshot of their key metrics:
| Metric | Walmart | Costco |
|---|---|---|
| Market Cap | $729 billion | $407 billion |
| Forward P/E Ratio | 34 | 47 |
| Dividend Yield | 0.91% | 0.49% |
| Gross Margin | 24.7% | 12.7% |
The Case for Walmart as the Better Buy
Costco’s membership model provides a reliable revenue stream, but Walmart’s diversified business gives it the edge in terms of growth potential and resilience. While both stocks are priced at a premium, Walmart’s valuation is more reasonable, and its lower dependence on membership revenue makes it less vulnerable to consumer spending shifts.
Additionally, Walmart’s focus on automation, digital integration, and subscription-based services positions it well for long-term growth. Its ability to maintain competitive pricing and grow internationally further strengthens its case.
A Word of Caution
Despite their strengths, both stocks are trading at inflated valuations, partly due to investor preference for stable, recession-resistant businesses. While these companies are solid long-term investments, current prices may limit near-term upside. Investors might benefit from waiting for more favorable entry points or exploring other opportunities in the market.
