Uber is investing hundreds of millions of dollars into Lucid and autonomous vehicle technology startup Nuro in a bid to launch its own robotaxi service.

Lucid shares jumped 36% Thursday on news the EV startup is partnering with self-driving software maker Nuro and rideshare giant Uber Technologies to bring a new group of robotaxis to Uber's platform.

The partnership will combine Uber's ride-sharing platform with Lucid's new electric SUV, the Gravity, and Nuro's autonomous driving technology. It'll be launching first in an unnamed "major US city," but is expected to roll out globally to more than 20,000 Lucid vehicles over the next six years.

Lucid’s stock zooms to best day in months after Uber becomes the EV maker’s latest backer and the companies hatch a plan to launch robotaxis.

Tesla's robotaxi encountered three disengagements or human interventions during Business Insider's test of the service.
