Uber Divests Entire Ownership Stake in Sidewalk Delivery Firm Serve Robotics

Uber has divested its entire ownership stake in autonomous delivery robot manufacturer Serve Robotics, according to a recent regulatory disclosure first reported by Bloomberg. The move marks a significant shift in the relationship between the ride-hailing giant and the robotics firm, which originally spun out of Uber-owned Postmates several years ago.

What Happened

According to regulatory filings, Uber’s exit from Serve Robotics developed over the past year, with the company gradually reducing its equity holding throughout 2025 before executing a complete sell-off. A source familiar with the situation indicated that the final divestment came as a surprise to Serve Robotics, which learned of the sale only after the official filing was submitted. Uber could not be immediately reached for comment on the transaction.

Serve Robotics originated as Postmates X, the internal robotics division of food delivery service Postmates. Uber acquired Postmates in 2020 in a deal valued at $2.65 billion. In 2021, the robotics division was spun off into an independent entity named Serve Robotics, after the autonomous sidewalk delivery bots it designed and tested.

Key Highlights

  • Uber has sold 100% of its equity in Serve Robotics after progressively trimming its holding in 2025.
  • Serve Robotics originated as Postmates X before spinning out as an independent firm in 2021 following Uber’s $2.65 billion acquisition of Postmates in 2020.
  • In May 2023, the two companies expanded an existing commercial partnership to deploy up to 2,000 sidewalk delivery robots across multiple United States markets on the Uber app.
  • Delivery volumes via Uber declined in the second quarter due to lower-than-projected robot utilization, halting a 17-quarter growth run.
  • Serve Robotics leadership noted divergence over operational models, including fleet coordination and merchant integration.
  • Serve Robotics does not expect to renew its commercial contract with Uber when the agreement concludes in early 2027.

Why This Matters

The divestment highlights diverging operational priorities between the two companies. During Serve Robotics’ second-quarter earnings call on August 6, co-founder and Chief Executive Officer Ali Kashani noted that delivery volume through the Uber platform had expanded for 17 consecutive quarters from the first quarter of 2022 through the first quarter of this year before reversing in the second quarter because of lower-than-expected robot utilization.

Kashani stated that the companies hold differing views regarding the operational framework required to scale their shared autonomous fleet, particularly in areas concerning merchant integration and fleet coordination. While activity on Uber contracted, Serve Robotics recorded a nearly 50 percent quarter-over-quarter delivery increase with an alternative food delivery partner.

What to Watch Next

The current commercial agreement between Uber and Serve Robotics remains active but is slated to expire in early 2027. Given the operational disagreements and recent performance trends, Serve Robotics has stated it does not expect to renew the partnership upon its expiration. Meanwhile, Uber continues its broader automated technology strategy, maintaining investments or partnerships with more than 30 autonomous vehicle technology firms.

Frequently Asked Questions

How did Serve Robotics originate?

Serve Robotics began as Postmates X, the dedicated robotics branch of Postmates. When Uber bought Postmates for $2.65 billion in 2020, it backed the division’s spin-out into an independent company the following year.

Why did delivery volumes on Uber decline for Serve Robotics?

According to Serve Robotics CEO Ali Kashani, delivery volume growth reversed in the second quarter due to lower-than-anticipated utilization of the delivery robots on the Uber platform.

Will Serve Robotics still operate on the Uber app?

The existing partnership established terms to deploy up to 2,000 robots across various US markets. However, Serve Robotics has indicated it does not expect to extend or renew the operating contract when it ends in early 2027.
