Costco Reports Strong May 2026 Sales, Digital Growth Outpaces Overall Retail
Costco Wholesale Corporation (NASDAQ:COST) announced that its net sales for the four‑week period ending May 31, 2026 were $24.01 billion, a 14.5 % increase from $20.97 billion a year earlier. For the first 39 weeks of fiscal 2026, net sales totaled $221.19 billion, up 10.0 % year‑over‑year. The company also reported that total comparable sales for the May period grew 12.5 % and 8.3 % for the first 39 weeks, while digitally enabled comparable sales rose 21.1 % and 21.6 % respectively. Even after removing the effects of gasoline‑price and foreign‑exchange fluctuations, digitally enabled comparable sales increased 20.9 % for May and 21.1 % for the 39‑week period.
The figures were released in a press statement issued by Costco’s investor relations office on June 3, 2026. The company’s data show that its e‑commerce and digitally enabled sales are expanding at a faster pace than the broader retail sector. Digitally enabled sales, which include online orders that are fulfilled from the company’s warehouses, accounted for a significant portion of the comparable‑sales growth.
Costco’s business model is built around a membership‑only warehouse‑club format that offers a limited assortment of goods at low prices. The company operates 931 warehouses and e‑commerce sites worldwide, with locations in the United States, Canada, the United Kingdom, Mexico, South Korea, Taiwan, Japan, Australia and China. The international footprint has helped the company sustain growth in markets where online shopping has accelerated during the pandemic and beyond.
Industry analysts note that the pace of digital sales growth at Costco is notable because the company’s core membership and bulk‑purchase model has traditionally relied on in‑store traffic. The 21 % rise in digitally enabled comparable sales indicates that a larger share of customers are turning to the company’s online platform, a trend that aligns with broader shifts in consumer behavior toward omnichannel retail.
Costco’s financial results for the first 39 weeks of fiscal 2026 also show that the company’s overall sales trajectory remains positive. Net sales grew 10 % year‑over‑year, and comparable sales increased 8.3 %. These numbers suggest that the company’s membership base and product mix continue to support steady revenue growth.
The company did not issue any statements regarding future plans in the press release. However, the data imply that Costco is maintaining its expansion strategy, with a focus on both physical and digital channels. The company’s continued investment in e‑commerce infrastructure is expected to support the ongoing growth of digitally enabled sales.
Costco’s next earnings announcement is scheduled for the end of the third fiscal quarter. The company reported operating results for the third quarter and the first 36 weeks of fiscal 2026 on May 28, 2026. Investors will likely examine the upcoming quarterly report for guidance on membership growth, inventory levels, and the trajectory of digital sales.
The company’s performance remains a point of interest for investors who track the warehouse‑club sector. While the press release does not provide forward‑looking guidance, the strong sales figures and the accelerated growth of digitally enabled sales provide a snapshot of Costco’s current market position.
In summary, Costco’s May 2026 sales data demonstrate robust growth in both overall and digital channels, with the company’s international network and membership model underpinning continued expansion. The company’s forthcoming quarterly report will provide further insight into its financial health and strategic priorities.
