DoorDash and Uber Eats to offer delivery from US Costco stores

Uber Eats and DoorDash have expanded their partnerships with Costco to provide nationwide delivery of groceries, electronics, and household items. This strategic move directly challenges Instacart's dominance within the same-day grocery delivery sector. DoorDash noted that Costco was one of the most-searched retailers previously unavailable on its U.S. platform. These new agreements allow both delivery giants to offer a wider range of products to consumers, increasing competition for existing market leaders in the industry.
