Uber and Pony.ai Launch Commercial Robotaxi Service in Zagreb

Uber has partnered with Chinese autonomous driving firm Pony.ai and mobility operator Verne to launch a commercial robotaxi service in Europe. The operation begins in Zagreb, Croatia, marking a strategic expansion of driverless ride-hailing into the European market.

The collaboration creates a three-way integration of specialized capabilities: Pony.ai provides the autonomous driving technology stack, Verne manages the physical fleet operations, and Uber provides the demand platform to connect passengers with vehicles. This structure allows the partners to deploy autonomous vehicles (AVs) directly into a live commercial environment using Uber's existing user interface.

A Shift in Strategy

This move reflects a broader pivot in Uber's approach to autonomy. Rather than developing its own proprietary self-driving software, Uber has transitioned to a partner-led model. By collaborating with various autonomy providers, Uber aims to integrate diverse third-party fleets into its app, effectively becoming the primary marketplace for autonomous mobility.

For Pony.ai, the Zagreb launch is a key component of an aggressive "dual-engine" growth strategy. The company is actively seeking to diversify its footprint beyond the Chinese market, targeting expansion across Europe and the Middle East to establish a global presence.

The Race for Scale

Industry analysts suggest this partnership signals a critical phase in robotaxi commercialization. As the technology matures, the primary competitive advantages are shifting away from pure software development toward fleet size and platform integration. By leveraging Uber's massive global user base and Pony.ai's scaling capabilities, the venture seeks to prove that driverless ride-hailing is viable within the complex urban environments typical of European cities.

Pony.ai is pursuing an ambitious scaling timeline to support this expansion. The company aims to deploy more than 3,000 robotaxis across more than 20 cities globally in 2026. According to company targets, nearly half of those vehicles are intended for overseas markets, highlighting the importance of the European rollout.

What's Next

While the Zagreb launch establishes a commercial foothold, the long-term success of the venture depends on the ability to scale the fleet across additional European cities. Observers will be watching for further city announcements and data regarding the operational efficiency of the Pony.ai stack in diverse weather and traffic conditions. It remains to be seen how quickly the partnership can expand its vehicle count to meet its 2026 global targets.
