Uber Sells Stake in Serve Robotics: Reasons and Implications

Uber has completed the sale of its stake in Serve Robotics, a developer of autonomous delivery robots. The news emerged from regulatory filings published this week. The ride-hailing and delivery giant had gradually reduced investments in the startup over the past year, but the final exit came as a surprise to Serve Robotics’ leadership, which only learned of the deal after its completion.

Serve Robotics originated from Postmates X, the robotics division of Postmates. After Uber acquired Postmates for $2.65 billion in 2020, the project spun off into an independent company. Uber not only invested in the startup but also established a partnership agreement: in 2023, the companies agreed to deploy up to 2,000 Serve robots in Uber’s app across several U.S. cities.

However, collaboration began to falter in recent months. As Serve Robotics CEO Ali Kashani noted, delivery volumes via Uber declined in Q2 due to low robot utilization. The companies failed to agree on a scaling model for the autonomous fleet, including coordination and restaurant integration. As a result, Serve Robotics does not plan to renew its agreement with Uber, which expires in early 2027.

Despite the split, the startup is growing with other partners: delivery volumes surged nearly 50% in a single quarter. Serve Robotics remains one of over 30 autonomous transport technology projects Uber has collaborated with or invested in over the years.
