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.

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.
