Uber’s latest quarterly holdings disclosure shows it exited Serve Robotics and added Rivian and Lucid

Uber’s changing equity portfolio is showing up in the company’s quarterly institutional holdings disclosure, according to a market update that summarizes the positions Uber reported for the period ended June 30.

The update says Uber reported seven “reportable” equity positions in that filing, but did not list Serve Robotics, which has been a focus for investors following Uber’s earlier stake in the delivery robotics company. In other words, the disclosure implies Uber’s involvement in Serve Robotics has ended, at least in terms of what it was required to report for that quarter.

The same summary reports that Uber added shares in two electric-vehicle makers, Rivian and Lucid. The inclusion of these names alongside the absence of Serve Robotics suggests Uber adjusted its public-market exposure during the quarter, even if it did not provide details on when it traded or why it made those changes.

While the post frames the shift as a “fully exits” development for Serve Robotics, the company’s disclosure is essentially a snapshot based on reporting thresholds and filing requirements, not a trading diary. Positions that fall below reportable levels or move in and out of the threshold can change how holdings appear from one quarter to the next.

Uber’s holdings disclosure is part of a broader category of regulatory information that large institutional investors report each quarter, listing certain equity positions held as of specific dates. These reports are watched because they can announcement whether a company or its investment arm is increasing, reducing, or exiting particular public-market bets.

In the case of the names involved here, Serve Robotics represents the intersection of logistics and automation, while Rivian and Lucid represent competing approaches to electric vehicle manufacturing and software-driven vehicle experiences. Moving away from a robotics delivery bet and toward EV makers can be read as a rotation of risk and time horizon, though the disclosed data does not explain the rationale.

What is not disclosed in the market update is any valuation impact, the size of Uber’s prior Serve Robotics position, or the magnitude of its Rivian and Lucid additions. The post also does not indicate whether Uber retained exposure through other vehicles or whether there were related hedges or derivatives that would not appear the same way in equity-only reporting.

For investors and observers, the main next step is to watch Uber’s future quarterly disclosures to confirm whether Rivian and Lucid remain on the list for subsequent reporting periods, and to see whether Serve Robotics stays absent. If the pattern persists, it would reinforce the idea that Uber has structurally exited that robotics bet rather than only letting it fall below a reporting threshold.
