On June 9, 2025, Costco's trading volume reached 17.05 billion, ranking 33rd in the day's stock market. The stock price of Costco Wholesale Corporation (COST) decreased by 0.86%.

Costco Wholesale Corporation maintained its strong comparable sales growth trend in May, driven by its appeal to value-focused shoppers. The company's ability to offer quality merchandise at competitive prices, both in-store and through its expanding e-commerce platform, continues to attract consumers in an inflationary environment.

For the four weeks ending June 1, 2025, Costco reported a 4.3% year-over-year increase in total company comparable sales. Regionally, comparable sales rose 4.1% in the United States, 3.3% in Canada, and 6.6% in other international markets. This follows gains of 4.4% in April and 6.4% in March, indicating consistent momentum.

Excluding the impacts of gasoline price fluctuations and foreign exchange, comparable sales were even more robust. U.S. comps climbed 5.5%, while Canada and other international markets posted increases of 6.3% and 8.4%, respectively. Overall, total company comps, excluding these factors, grew 6%, following strong rises of 6.7% in April and 9.1% in March.

E-commerce remained a bright spot, with comparable sales surging 11.6%, or 12% when adjusted for fuel and currency headwinds. This builds on gains of 12.6% in April and 16.2% in March, reflecting sustained strength in Costco’s online channel.

As a result, Costco's net sales for May increased 6.8% to $20.97 billion, up from $19.64 billion in the same period last year. This follows a sales improvement of 7% and 8.6% reported in April and March, respectively.

Costco's resilient business model, centered around a membership-based structure, continues to be a major growth driver. The company’s high membership renewal rates, coupled with its efficient supply-chain management and bulk purchasing power, ensure competitive pricing and customer loyalty.
