Shares of Lucid Group (LCID) soared 40% on Thursday morning after the EV maker announced that Uber Technologies (UBER) plans to deploy 20,000 or more of its vehicles on the Uber platform as robotaxis.

The move is the result of a three-way partnership between Lucid, Nuro, and Uber for a next-generation autonomous robotaxi. It’s expected to be launched next year in a major US city, although the companies were hesitant to say which one.

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.
