Read MoreHide Full Article
Key Takeaways
COST's digitally enabled comparable sales rose 18.8% in April and 21.6% over the first 35 weeks.
Adjusted for gas and FX, COST's digital comps still gained 18.4% in April and 21.1% for the first 35 weeks.
Costco's e-commerce presence now spans several international markets.
Costco Wholesale Corporation’s (COST - Free Report) rapidly expanding e-commerce business is increasingly becoming a factor that could support a richer market valuation for the retailer. While the company has long been associated with warehouse traffic and membership loyalty, the latest sales update suggests its digital business is now contributing to growth in a more material way.
Digitally enabled comparable sales increased 18.8% in April and climbed 21.6% for the first 35 weeks ended May 3, 2026. Even after adjusting for gasoline prices and foreign exchange, digitally enabled comparable sales still rose 18.4% in April and 21.1% for the first 35 weeks. Those figures significantly outpaced the company’s overall comparable sales growth of 11.6%, indicating that Costco’s online ecosystem is scaling faster than its core warehouse business.
Strong digital momentum suggests that Costco is expanding customer engagement beyond in-store bulk shopping while reinforcing convenience for existing members. The company’s e-commerce presence now spans several international markets, including the United States, Canada, the United Kingdom, Mexico, Korea, Taiwan, Japan and Australia.
In an environment marked by inflationary pressures and uncertain consumer spending patterns, Costco’s digital growth may be strengthening investor confidence that the retailer can sustain revenue growth across multiple shopping channels. The acceleration of these digital channels serves as a powerful catalyst for a higher valuation because it diversifies revenue streams and captures a broader share of member spending.
What the Latest Metrics Say About Costco's Valuation
From a valuation standpoint, Costco's forward 12-month price-to-earnings ratio stands at 46.37, higher than the industry’s ratio of 32.36 but below its median P/E level of 46.88, observed over the past year. Although the premium multiple may appear elevated, investors often view Costco as a high-quality retail operator supported by resilient comparable sales growth, strong membership retention and expanding digital capabilities.
As long as Costco continues to deliver consistent sales growth and strengthen its omnichannel presence, its premium valuation could remain supported by investors seeking stable growth within the retail sector.

(WMT - Free Report) continues to scale its digital ecosystem aggressively, with e-commerce sales rising 24% globally and contributing 23% of total sales during the fourth quarter of fiscal 2026.

Walmart’s comparable sales growth of 4.6% in the U.S. division reflects increased customer transactions supported by digital adoption.
