Uber and Alphabet’s Waymo have ended their driverless-car partnership in Phoenix, the city where the two first tested whether longtime rivals could work together. Both companies confirmed the split on Monday, with an Uber spokesperson describing Phoenix as “our first pilot market with Waymo” and “an intentionally limited deployment, reaching just over a dozen vehicles dedicated to the program.”

The arrangement dated to a multiyear deal struck in 2023, under which Uber put a subset of Waymo’s robotaxis on its ride-hailing and food-delivery apps. The ride-hailing portion wound down last month, and the food-delivery piece had ended back in May 2025, after the program completed hundreds of thousands of trips. A Waymo spokesperson said the vehicles have already been integrated back into its own Phoenix fleet, where riders can still book them through the Waymo app.

The breakup is less a falling-out than a fork in the road. Uber and Waymo are an unusual pair — former courtroom rivals who became partners while still competing — and each is now pursuing a separate autonomous strategy. Waymo increasingly wants riders in its own app, and Uber wants to be the platform every robotaxi maker plugs into. Phoenix is where those two visions stopped overlapping.

For Waymo, the split shows growing confidence in going it alone. The Google sister company operates a fleet of about 4,000 automated vehicles in the United States, offers rides through its own app in most markets, and is expanding to new cities without Uber, launching in Dallas with Moove and Avis as fleet partners. In Phoenix, its vehicles will remain in use and will make autonomous deliveries through DoorDash, which competes directly with Uber Eats.

Uber, meanwhile, is spreading its bets. Its broader autonomous strategy now spans far beyond Waymo, with partners including Wayve, Avride, and a recently announced agreement for up to 50,000 Rivian-built robotaxis. Waymo vehicles remain available exclusively through Uber in Austin and Atlanta, and Uber says it is preparing another autonomous-vehicle partnership in Phoenix, though it has not yet identified the company. The strategy is to make Uber the front door for autonomous rides regardless of which company’s technology powers the vehicle.

The stakes are enormous because robotaxis have the potential to transform the economics of ride-hailing. Removing the human driver eliminates the industry’s largest operating cost, potentially lowering fares while increasing profit margins for whichever company controls the fleet. That explains why both companies are racing to control as much of the value chain as possible—from the self-driving technology to the customer-facing app and the vehicles themselves.

The shift also reflects an increasingly crowded autonomous-driving race. Waymo is rolling out its newest robotaxi, the Zeekr-built Ojai, and plans to launch rides through Lyft in Nashville later this year without exclusivity. Tesla, which obtained an Arizona ride-hailing permit last fall, is currently operating a limited autonomous fleet of roughly 69 vehicles in Texas. Each competitor is positioning itself in what many believe will become one of transportation’s largest future markets.

The Phoenix split also comes as the industry faces greater scrutiny over safety. Waymo recently recalled nearly 3,900 robotaxis after identifying a software issue that could allow vehicles to enter closed freeway construction zones. Incidents like that carry significant business consequences, influencing both regulatory oversight and public confidence as autonomous fleets continue expanding.

For riders in Phoenix, little changes immediately. The same driverless vehicles will continue operating on city streets—they will simply be requested through a different app.

The larger battle, however, is only beginning.

The central question facing the entire autonomous-vehicle industry is who ultimately owns the customer relationship: the company that builds the self-driving technology or the platform millions of people already use to request rides.

Phoenix has made one thing clear: Uber and Waymo now have very different answers, and the outcome of that competition will help determine how Americans book—and pay for—driverless transportation in the years ahead.
