Costco Wholesale Corporation and DoorDash have launched Costco on the DoorDash Marketplace nationwide, putting the warehouse club on its second major delivery platform in two days and completing a marketplace sweep timed a week ahead of the retailer’s fiscal 2026 earnings report.
Costco members can now order groceries, pantry staples, household essentials, electronics, seasonal merchandise and Kirkland Signature products from all U.S. Costco warehouses through DoorDash for same-day delivery, shopping more than 4,000 products per warehouse.
The launch follows Wednesday’s announcement expanding Costco on Uber Eats to 47 states, and with the club’s longstanding Instacart-powered same-day delivery, Costco now reaches shoppers on all three major U.S. delivery marketplaces.
“Costco members have been asking for Costco on DoorDash, and today we’re delivering,” said Mike Goldblatt, VP of enterprise partnerships at DoorDash, which is based in San Francisco. “By pairing Costco’s quality, value and selection with DoorDash’s reach and local delivery network, we’re giving members more flexibility in how they shop.
“The U.S. launch also marks the next chapter in a global partnership already serving Costco members around the world.”
The mechanics
The membership gate stays intact on the new channel: Members link an active Costco membership in the DoorDash app when prompted, while non-members are directed to Costco.com to purchase a membership before completing an order, preserving the club model’s economics even as access widens. DoorDash said Costco ranked among the most-searched retailers not yet available on its platform.
The U.S. launch extends a global DoorDash-Costco relationship already spanning Australia, New Zealand, Sweden, Iceland and Puerto Rico.
Costco, based in Issaquah, Washington, operates 939 warehouses worldwide, including 647 in the U.S. and Puerto Rico, and closed fiscal 2026 with sales of $297.3 billion, up 10.2 percent, powered in part by digitally-enabled comparable sales growth of 20.9 percent. The company reports fourth quarter and full-year earnings Sept. 24.
