Waymo is expanding its commercial driverless taxi service into three additional American cities: Denver, San Diego, and Tampa. The Alphabet-owned company is opening fully autonomous rides to members of the public in the three markets after months of mapping, testing, and employee-only operations. Access will initially be introduced gradually, with interested customers joining through the Waymo app before the services are opened more broadly.

The rollout represents the culmination of a process Waymo announced in July, when it began operating without human safety drivers in Las Vegas, and said Denver, San Diego, and Tampa would soon follow. Before removing the driver, Waymo typically maps a city, operates vehicles manually, conducts autonomous testing with specialists aboard, and eventually begins driverless employee rides. Only after those stages does it begin carrying ordinary customers.

Waymo’s expansion is an indication that autonomous ride-hailing is shifting from experimental technology into a genuine transportation industry. The expansion also demonstrates how quickly the robotaxi business is growing. In May 2024, Waymo was providing about 50,000 paid rides per week. By March 2026, that number had increased tenfold to approximately 500,000 weekly paid rides, spread across ten American cities. Waymo has set a goal of exceeding one million paid rides per week by the end of 2026.

The geographic diversity of the three new markets is particularly important. San Diego gives Waymo another major California market while Denver tests the company’s ability to operate in a city where snow, ice, and changing weather can create more difficult driving conditions. Denver’s initial service area encompasses roughly 60 square miles and includes downtown and surrounding neighborhoods, while Waymo eventually hopes to serve Denver International Airport.

In San Diego, the company similarly plans to expand toward highways and airport service after establishing its initial operation. Tampa strengthens Waymo’s position in Florida, where it already operates in Miami and Orlando. Waymo has raised $16 billion to finance additional vehicles and expansion, illustrating how investors increasingly regard autonomous taxis as a potentially enormous commercial market rather than simply a research project.

Waymo is not alone. Tesla has been developing its robotaxi operation, while Amazon-owned Zoox has begun charging customers for driverless rides in Las Vegas. But Waymo currently operates at a substantially larger scale, giving it an advantage in collecting real-world driving data and introducing consumers to autonomous transportation.

Taxi companies have complained that autonomous vehicles create unfair competition, while some residents remain skeptical about safety. In a recent Denver survey, 58 percent of people who had not used a robotaxi said they were unlikely to try one. San Diego transportation and taxi representatives have also raised objections to Waymo’s arrival.

Waymo’s expansion to Denver, San Diego, and Tampa represents an important milestone. The central question surrounding robotaxis is increasingly changing from whether autonomous ride-hailing can work to how quickly it can scale. If Waymo can successfully operate across cities with dramatically different traffic, weather and regulatory environments, driverless taxis may become a routine feature of American transportation much sooner than many consumers expected.
