How many cities will Waymo operate in by June 30?

Platform comparison

Market context

The real-world event this market tracks is the count of distinct cities where Waymo’s fully autonomous ride-hailing service is publicly bookable via the Waymo One app or Uber as of 30 June 2026. Currently, Waymo operates driverless 24/7 in ten cities, including Phoenix, San Francisco, Los Angeles, Miami, Dallas, Houston, San Antonio, Orlando, Nashville and Austin, with Austin and Atlanta also accessible exclusively through Uber[2][5]. This historical baseline frames the current 0% crowd-implied probability as a mispricing: the service already exists in ten cities, so the outcome “zero cities” is factually impossible, suggesting the market may be misinterpreting the settlement condition or the crowd is reacting to a technical glitch rather than the underlying event.

Traders should monitor Waymo’s expansion announcements, regulatory approvals in new states, and Uber partnership rollouts, as these are the primary catalysts for city count growth. In April 2026, City & State New York reported Waymo plans to expand to at least a dozen more cities beyond its current ten, indicating a clear trajectory toward higher counts[4]. Programmatically, this market would be approached by scraping Waymo’s official service-area pages and Uber’s autonomous vehicle toggle settings daily, then cross-referencing with state-level autonomous vehicle permits to confirm public availability. Any delay in regulatory clearance in states like New York, where human drivers are still required for testing, would be a key dependency to watch[4]. The settlement window ending 30 June 2026 leaves ample time for further city additions, making the zero-outcome claim highly improbable.
