Waymo and Uber quietly part ways in Phoenix

Waymo and Uber have officially concluded their autonomous vehicle partnership in Phoenix, Arizona, ending a three-year pilot program that began in 2023. While the companies continue to collaborate in Austin and Atlanta, the Phoenix exit marks a strategic shift as Waymo reintegrates its vehicles into its own proprietary fleet and Uber prepares to launch a new partnership with an unnamed autonomous provider. This move highlights the maturing robotaxi market and the increasingly complex relationship between the two companies as they transition from collaborators to potential global competitors.

The partnership in Phoenix officially ended in May 2026 at the conclusion of its contracted term, according to statements from both companies. The pilot was described by Uber as an intentionally limited deployment involving just over a dozen vehicles, though it served as a foundational step for larger operations in other cities. Waymo has since moved the vehicles used for the Uber program back into its own Phoenix fleet, where they continue to serve passengers through the Waymo One app and support integrations with partners like Via and DoorDash. While Phoenix was unique for being the only city where Waymo operated both directly and through Uber, the companies maintain that their ongoing exclusive partnerships in Austin and Atlanta remain robust.

The landscape of the autonomous vehicle sector has shifted dramatically since the collaboration was first announced in 2023. At that time, the industry was characterized by uncertainty, with Cruise still considered a major independent competitor before its eventual absorption into General Motors. Since then, Waymo has scaled significantly, growing its fleet to approximately 4,000 vehicles and providing more than 500,000 trips per week across 11 major U.S. metro areas. The company is currently in the process of launching in 20 new cities this year and is introducing its latest robotaxi hardware, the Zeekr-made van known as "Ojai," to the public.

Despite the successful conclusion of the Phoenix pilot, the relationship between Alphabet-owned Waymo and Uber is entering a more competitive phase. The two entities are reportedly preparing to compete directly against each other in London as early as this year. Uber has also been aggressive in diversifying its autonomous offerings, inking deals with dozens of other AV partners to populate its network. This evolution reflects a broader industry trend where early-stage research and development partnerships are giving way to market-share battles as robotaxi technology reaches commercial scale and moves beyond the experimental phase.
