Uber has sold its entire stake in Serve Robotics, an autonomous delivery robot company, first reported by TechCrunch. The sale comes as the companies have started to diverge on the business side, with differing views on scaling the shared autonomous fleet; Serve did not expect that it would make sense to renew the partnership when it expires in early 2027.
The exit had been in motion for at least a year. Regulatory filings show Uber reduced its stake in 2025, but the final selloff surprised Serve, which learned about it once it was officially disclosed, according to a source familiar with the events.
Serve began as Postmates X, the robotics division of Postmates, which Uber acquired in 2020 for $2.65 billion. A year later, the division spun out as an independent company called Serve Robotics, taking the name of the autonomous sidewalk delivery bot that Postmates X developed and piloted.
Uber backed Serve and entered a partnership with the company in 2022. The companies expanded that partnership in May 2023 to deploy up to 2,000 of Serve’s sidewalk bots onto Uber’s app in multiple markets in the United States.
At Serve’s August 6 second-quarter earnings call, co-founder and CEO Ali Kashani said delivery volume through Uber grew for 17 consecutive quarters, from the first quarter of 2022 through the first quarter of this year. The trend reversed in Q2 because of lower-than-expected robot utilization.
Kashani also said the companies had differing views about the operating model for scaling the shared autonomous fleet, including fleet coordination and merchant integration. During the same time frame, Serve’s deliveries with another food delivery partner grew nearly 50% in a single quarter.
Uber’s Q2 reversal and Serve’s nearly 50% increase in deliveries with another food delivery partner sit alongside the companies’ differing views on scaling the shared autonomous fleet. Kashani said Serve did not expect that it would make sense to renew the partnership agreement when it expires in early 2027.
Uber has partnered with or invested in more than 30 autonomous vehicle technology companies over the past several years.
