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

Uber will invest $300 million in electric vehicle maker Lucid in a robotaxi deal that aims to start with one major U.S. city late next year, the companies said on Thursday.

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.
