Uber surprised robotics company Serve by selling its entire stake
Uber has sold its entire stake in Serve Robotics, the autonomous sidewalk delivery robot company that spun out of the ride-hailing giant more than five years ago, according to a regulatory filing first reported by Bloomberg. The sale appears to have blindsided Serve itself, which only learned of the move once it was officially disclosed, and comes as the two companies' commercial relationship has been cooling.
Serve began life as Postmates X, the robotics arm of Postmates, which Uber acquired in 2020 for $2.65 billion before it spun out as an independent firm the following year. Uber had backed Serve and partnered with it from 2022, expanding the deal in 2023 to deploy up to 2,000 delivery robots across US markets, but growth through Uber's app stalled in the second quarter of this year due to lower robot utilisation, while deliveries via another partner grew nearly 50%. Serve's chief executive, Ali Kashani, said the firms now have "differing views" on scaling the fleet and does not expect to renew the partnership when it expires in early 2027; Uber has invested in or partnered with more than 30 autonomous vehicle firms in recent years and could not be reached for comment.

- Partnership between the firms is unlikely to be renewed in 2027
New here? Start with this
Uber's takeover of Serve Robotics goes back to 2020, when it bought the delivery firm Postmates and, with it, an in-house robotics team then known as Postmates X. That unit was spun off as its own company, Serve Robotics, the following year, and Uber went on to invest in it and use its sidewalk delivery robots for food and parcel drop-offs in several US cities.
The two firms' relationship deepened in 2023 with a plan to put up to 2,000 robots to work through Uber's app, making Uber one of Serve's most important business partners alongside its own investment stake. Serve's chief executive is Ali Kashani, while Uber has separately built a wide portfolio of stakes and tie-ups with dozens of self-driving and robotics companies.
That backdrop matters because it shows Uber and Serve were not just occasional collaborators but tightly linked through ownership, funding and a live commercial contract, one due to run until early 2027. Any change in that relationship has knock-on implications for Serve's operations and for how Uber positions itself within the wider autonomous delivery and robotics industry.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Advocates for Uber's decision would point out that a corporate parent is not obliged to remain a permanent shareholder in a spun-out venture, especially once the commercial relationship has cooled and performance data no longer supports it: Serve's robot utilisation and deliveries through Uber's app had stalled even as growth through a rival partner surged nearly 50%. With more than 30 autonomous vehicle bets in its portfolio, Uber can reasonably argue that reallocating capital away from an underperforming, non-core equity position towards more promising partners is sound, disciplined business practice rather than any betrayal.
The case against
Critics sympathetic to Serve would argue that blindsiding a five-year strategic partner and former subsidiary by selling out entirely without warning, only for Serve to learn of it via a public filing, reflects a troubling disregard for the trust and goodwill such long-term relationships depend on. Given that Uber effectively created Serve, championed its rollout, and expanded their delivery agreement as recently as 2023, a more transparent, collaborative wind-down would have better respected the smaller company's stability, workforce and investors who were left to absorb the shock alongside the market.
