Costco's Digital Sales Top $33 Billion: Can E-commerce Keep Scaling?
Read MoreHide Full Article
Key Takeaways
Costco's digitally enabled sales exceeded $33 billion in fiscal 2026 and grew more than 20%.
Same-day delivery through Uber Eats, DoorDash and Instacart averages under an hour and appears incremental.
Personalized placements, emails and AI search drove strong growth.
Costco Wholesale Corporation’s (COST - Free Report) digital business is becoming an increasingly meaningful part of its retail ecosystem. In fiscal 2026, digitally enabled sales, including third-party delivery, exceeded $33 billion and grew more than 20%. Momentum remained strong in the fourth quarter, when digitally enabled comparable sales rose 19.5%, or 19.8% excluding foreign-exchange impacts. E-commerce site and app traffic also climbed 30%.
The growth is broad-based rather than concentrated in one merchandise area. Pharmacy, home furnishings, small electrics, hardware, housewares and domestics ranked among Costco’s strongest digital sales categories during the quarter. At the same time, Costco is extending same-day availability through Uber Eats, DoorDash and Instacart. Management noted that average delivery times across these platforms are under an hour and that the transactions appear mostly incremental instead of shifting purchases away from warehouses.
The company is simultaneously improving how members discover products online. Personalized product placements and email communications generated triple-digit sales growth in the fourth quarter, while 10% of Costco.com orders included a personalized item. Traffic originating from AI search also grew at a triple-digit rate for the second straight quarter and delivered the highest conversion rate among site traffic sources.
For Costco, continued e-commerce scaling increasingly depends on making digital shopping faster, more relevant and complementary to warehouse visits.
How Walmart & Target Are Scaling Digital Sales

Target is supporting this momentum through digital personalization, AI-powered shopping tools and enhanced app experiences. Target’s digital traffic from external AI platforms is also rising more than 3.5 times the industry rate, suggesting Target is increasingly using technology and convenience to strengthen online discovery and engagement.
