Uber Stock Climbed on Robotaxi Hopes. But It Doesn't Own the Autonomous Cars Driving Its Expansion.

Uber's stock has risen on robotaxi optimism, but the company doesn't own the autonomous vehicles or self-driving technology powering its expansion. Instead, it operates as a platform aggregating partners' robotaxis. While this asset-light model could be advantageous if autonomy fragments across many operators, it poses risks if competitors like Waymo scale independently. Uber has committed over $10 billion to secure its own robotaxi supply through deals with Lucid and Rivian, though deployments won't materialize until 2026-2028.
