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 $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.
