Uber has announced a multi-million dollar partnership with U.S. electric vehicle maker Lucid and robotics company Nuro. The three companies plan to deploy at least 20,000 robotaxis "in dozens of markets around the world" over the next six years, starting in a major U.S. city in 2026.

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

Uber is adding Lucid electric vehicles equipped with Nuro's self-driving technology to its growing robotaxi network, and is buying a stake in both companies. Why it matters: The deal is important to all three partners.
