Uber has sold its remaining equity stake in Serve Robotics, according to TechCrunch, ending a financial link to the sidewalk delivery-robot company that grew out of Postmates before becoming an independent public company.

The reported exit is notable because Serve's history is closely tied to Uber. Serve's SEC registration statement says the project began inside Postmates in 2017. After Uber acquired Postmates in 2020, Uber approved the contribution of the related intellectual property and assets to the company in February 2021. Serve later went public and now trades on Nasdaq under the ticker SERV.

The ownership relationship had already been shrinking. A September 2025 Schedule 13D/A showed Uber beneficially owned 2,070,629 Serve shares, with sole voting and dispositive power over those shares. TechCrunch reported that the final sale was disclosed in a regulatory filing first reported by Bloomberg and that Serve learned about the sale once it was officially disclosed.

The commercial relationship is separate from the equity position. Serve's filings say its robots are integrated with delivery platforms including Uber Eats and DoorDash, allowing the robots to receive delivery requests and share status updates through those platforms. That means Uber can remain a distribution partner even without holding Serve stock.

For Serve, the practical question is whether losing Uber as a shareholder changes investor confidence more than operations. The company still has to prove that autonomous sidewalk delivery can scale beyond pilots and selected markets, but the latest sale makes that challenge more independent from Uber's balance sheet.
