Amazon is switching restaurant delivery partners, dropping Grubhub in favor of Uber Eats as the official option for Prime members in the United States.

The deal ties Uber's delivery network into Amazon's own platforms: Prime members will be able to place restaurant orders through Amazon and, on some orders, skip delivery fees entirely, according to Engadget. For Amazon, it swaps a struggling partner for the market's dominant player; for Uber, it opens a direct pipeline to Prime's enormous US subscriber base.

The move is a blow to Grubhub, which had leaned on the Amazon partnership as a source of order volume while losing ground to Uber Eats and DoorDash. Losing placement inside the Prime bundle removes one of its few structural advantages in a market where it has steadily shrunk.

For consumers, the practical change is straightforward: the delivery perk attached to a Prime subscription now routes through a different app, and the fee waivers apply to orders placed on Amazon's side of the integration rather than everywhere on Uber Eats.
