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

The ride-sharing company also announced it’s making separate multi-hundred-million dollar investments in both Lucid and Nuro.

Uber is investing $300 million in Lucid, a spokesperson for the automaker, Nick Twork, confirmed. The investment in Nuro will be “significantly more than that,” Ferguson said, though he declined to share an exact figure. As part of the deal, Uber will take a seat on Nuro’s board of directors.
