Uber has acquired a larger stake in Careem Technologies for $100 million. Simultaneously, Tesla has expanded its Robotaxi program in Austin, offering the service in the entire metropolitan area. The move underscores growing focus on autonomous transportation and ride-hailing services.

Uber ([UBER](/stocks/UBER)) has invested an additional $100 million to expand its stake in Careem Technologies, the Middle East ride-hailing and 'super app' it has backed for years. The move deepens Uber's exposure to a high-growth regional platform spanning mobility, delivery, and digital payments, though full deal terms were not disclosed.

Separately, Tesla ([TSLA](/stocks/TSLA)) has widened its Robotaxi program in Austin, its initial launch city, extending the service's geofence to cover the entire metropolitan area in what marks the program's fifth expansion [doc3]. Analysts view the broader coverage as a signal that Tesla is pushing to prove the commercial viability of driverless ride-hailing at city scale.

Together, the two developments highlight an intensifying race in autonomous and on-demand transportation. Uber is reinforcing its asset-light marketplace and regional reach, while Tesla presses its bet on owned-fleet autonomy, framing a competitive dynamic, partner versus rival, that will shape how the robotaxi market monetizes over the next few years.
