Uber fully exits stake in Serve Robotics amid strategic divergence
Uber has sold its entire holding in Serve Robotics, a move disclosed in regulatory filings that surprised the spin-out company. The exit follows a year-long reduction in shares and reflects deepening disagreements over operating models and robot utilisation.
Uber has completed the sale of its entire stake in Serve Robotics, the autonomous sidewalk delivery company that originally spun out from the ride-hailing giant more than five years ago. The divestment was disclosed in a regulatory filing first reported by Bloomberg, marking the end of a financial relationship that began shortly after Uber’s $2.65 billion acquisition of Postmates in 2020.
The final selloff came as a surprise to Serve Robotics, which learned of the transaction only upon its official disclosure. While the exit had been brewing for at least a year, with regulatory filings indicating Uber began reducing its stake in 2025, the complete withdrawal signals a definitive break between the two entities. Uber could not be immediately reached for comment regarding the decision.
The divergence stems from fundamental disagreements on how to scale the shared autonomous fleet. During Serve’s second-quarter earnings call on August 6, co-founder and chief executive Ali Kashani cited differing views on operating models, specifically regarding fleet coordination and merchant integration. These strategic misalignments have coincided with a downturn in performance metrics for the partnership.
Kashani noted that delivery volume through Uber had grown for 17 consecutive quarters from the first quarter of 2022 through early this year. However, that trend reversed in the second quarter due to lower-than-expected robot utilisation. In contrast, Serve Robotics reported that deliveries with another food delivery partner grew nearly 50 per cent in a single quarter during the same period, highlighting the disparity in operational success.
Serve Robotics originated as Postmates X, the robotics division of the on-demand delivery startup Uber acquired in 2020. The division spun out as an independent entity in 2021, taking its name from the autonomous bot developed by Postmates X. Uber initially backed the firm and established a partnership in 2022, which was expanded in May 2023 to deploy up to 2,000 sidewalk bots onto Uber’s app across multiple US markets.
Despite the history of collaboration, Serve does not expect to renew its partnership with Uber when the current agreement expires in early 2027. The company is one of more than 30 autonomous vehicle technology firms Uber has partnered with or invested in over the past several years, but this exit underscores the increasing difficulty of integrating autonomous robotics into the broader gig economy model.
