SAN FRANCISCO — Uber Technologies Inc. divested its entire stake in Serve Robotics Inc. during the second quarter of 2026, ending a partnership that began when Serve spun out of Postmates. The exit followed an impasse over deployment strategy, and with the partnership agreement set to expire in early 2027, Serve Robotics is considering not renewing it.
Uber acquired Postmates for $2.65 billion in 2020. Serve Robotics emerged from Postmates' robotics unit after that deal, eventually going public through a reverse merger in 2023-2024. Uber had maintained an ownership stake in Serve ranging from 11 percent to 16 percent, making it a significant institutional holder.
The original agreement called for Serve to deploy up to 2,000 delivery robots on the Uber Eats platform for last-mile urban deliveries. The relationship deteriorated over disagreements on how and where the robots should operate.
Eduardo Rojas, a former member of Uber's Autonomous Mobility Delivery team, publicly discussed the deteriorating situation, pointing to declining revenue from the partnership and Serve's potential decision to terminate the deal.
For Uber, the loss goes beyond a single vendor. The company has spent years positioning itself as the platform layer for autonomous mobility, with third-party operators supplying the vehicles and Uber providing the marketplace and logistics backbone. The Serve exit tests that model.
Serve Robotics has built a fleet of more than 2,000 delivery robots and expanded to more than seven U.S. metropolitan areas, completing tens of thousands of deliveries. The company has also signed deals with more than 4,000 restaurants independently of Uber Eats, including 7-Eleven, Shake Shack and White Castle, reducing its reliance on any single platform.
In Jan. 2026, Serve acquired Diligent Robotics, moving beyond sidewalk delivery into indoor robotics for healthcare, hospitality and logistics.
Serve Robotics reported a 400 percent revenue increase in the second quarter of 2026. Over the same period, Uber delivery volume declined for the first time in 17 consecutive quarters, attributed to lower-than-expected robot utilization within the partnership.
Uber's exit from its Serve stake suggests the commercial terms it offers autonomous partners may not be attractive enough to sustain long-term commitments. The financial impact of robot deliveries on Uber Eats' overall volume remains small, but the strategic cost is harder to dismiss: Serve's origins inside Uber's own corporate family make the breakdown a direct test of whether Uber can retain the autonomous operators its platform model requires.
