Pony.ai and Uber began their partnership in May 2025. In spring 2026, they launched their first commercial robotaxi service in Europe in Zagreb, working with Croatian mobility company Verne. Passengers will soon also be able to book the service through the Uber platform.
The partners now plan to expand the service significantly. They aim to deploy more than 2,000 robotaxis across four additional European cities alongside Zagreb, although they have not yet disclosed the locations or when the fleet will reach that size. Pony.ai and Uber also plan joint operations in the Middle East.
Pony.ai provides its SAE Level 4-certified autonomous driving system and experience from existing robotaxi fleets, while Uber handles bookings, payments and customer service through its platform. At Level 4, vehicles can operate fully autonomously without human intervention within a defined operating area.
Local partners to operate fleets
To scale the service, Pony.ai and Uber will use a joint deployment model involving local partners. Depending on the market, these partners can handle financing, vehicle ownership and day-to-day fleet operations. In Zagreb, for example, Verne owns and operates the fleet, while Pony.ai supplies the autonomous driving technology and Uber connects the service with customers through its platform.
