Why is Costco partnering with DoorDash and Uber instead of expanding its own delivery network?

According to industry analysis in the article, this is an asset-light strategy. Costco avoids capital investment in vehicles and driver payroll while leveraging existing gig driver networks. RTMNexus CEO Dominick Miserandino notes that 'Costco isn't buying trucks or paying drivers' and instead lets delivery platforms 'take on the hassle,' keeping membership revenue untouched and forcing platforms to compete on fees and speed.

What geographic coverage does Costco now have through these delivery partnerships?

Uber Eats expanded Costco availability to 47 U.S. states (up from 17), covering nearly 600 locations. DoorDash launched nationally in the U.S. this week after operating in Australia, New Zealand, Sweden, Iceland, and Puerto Rico. Additionally, Costco is available on Uber Eats in Canada, Mexico, Japan, Taiwan, France, and Spain.

How does this reflect shifts in the broader parcel delivery market?

Alternative carriers (non-FedEx, UPS, USPS) now handle 8.5% of parcel volume, up from 2.6% in 2021. The article cites U.S. Census Bureau data showing online sales represent 16.5% of retail and grow at 10% annually, driving demand for lower-cost delivery alternatives. DoorDash now serves 8 of 10 largest food retailers in North America, indicating platform consolidation in last-mile logistics.

What competitive advantage does this partnership create for Costco?

Multi-channel delivery keeps members satisfied and drives incremental sales without major capital expenditure. By working with three platforms (Instacart, DoorDash, Uber), Costco creates competitive pressure on fees and service levels. The strategy also differentiates Costco from competitors by offering same-day delivery at scale, addressing growing customer expectations for ultra-fast fulfillment.

Is Costco still partnering with Instacart?

The article references Instacart as the incumbent provider ('For years, Instacart was the only real game in town for them'), suggesting the existing relationship continues. The addition of DoorDash and Uber represents expansion, not replacement, of Costco's delivery network.

The signal

Costco has significantly expanded its same-day delivery capabilities by launching comprehensive partnerships with DoorDash and Uber across the United States. DoorDash now offers Costco products through its marketplace nationwide, while Uber Eats has expanded from 17 to 47 states, covering nearly 600 Costco locations. This strategic move reflects a broader industry shift toward asset-light delivery models, where retailers leverage gig-economy platforms rather than building proprietary logistics networks. The expansion carries meaningful implications for supply chain professionals.

First, it demonstrates how traditional retailers are competing with e-commerce giants by outsourcing last-mile delivery to specialized platforms. 5% today. Third, the move underscores changing customer expectations: ultra-fast delivery is now table-stakes for major retailers, not a competitive advantage. For supply chain teams, this trend presents both challenges and opportunities.

Companies must reassess whether proprietary delivery networks remain economically viable, evaluate partnerships with emerging delivery platforms, and adapt demand planning to accommodate faster, more volatile fulfillment patterns. The structural shift toward platform-based fulfillment will likely continue reshaping parcel logistics and capital allocation decisions across retail and e-commerce.
