These expansions occur as the industry prepares for a major update from Tesla regarding its own planned robotaxi network and "Cybercab" hardware.
The growth of these fleets highlights a rapidly maturing market that Goldman Sachs Research estimates could reach $19 billion by 2030.
Waymo currently leads the U.S.
sector with more than 4,000 vehicles across 14 cities and a goal to facilitate one million trips per week by the end of 2026.
This scaling of autonomous infrastructure—the physical and digital systems required for driverless transport—intensifies the competition for market share in major urban centers.
To support this expansion, Waymo is deploying its new Ojai vehicles, which utilize a minivan-style chassis and sixth-generation driverless technology integrated with Gemini artificial intelligence.
While passengers in new markets can hail rides through a dedicated app, the industry continues to face scrutiny from labor groups and safety advocates regarding job displacement and the vehicles' performance in heavy traffic or construction zones.
Waymo intends to increase its presence in these new cities from dozens to hundreds of vehicles over time as it navigates these regulatory and technical challenges.
