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 shares soared Thursday after announcing a robotaxi partnership with rideshare giant Uber and self-driving software maker Nuro.
