Pronóstico: How many cities will Waymo operate in by June 30?

Platform comparison

Market context

Waymo is rapidly scaling its fully autonomous ride-hailing service across the United States, with public operations already spanning ten commercial metro areas as of early 2026, including major hubs like San Francisco, Phoenix, Austin, Dallas, Houston, Miami, Orlando, Nashville, and Los Angeles[1][2][3]. The market currently prices the contract at 0% YES for any expansion beyond this baseline by June 30, 2026, a stance that ignores the company’s explicit roadmap to launch in at least four additional US cities—Baltimore, Philadelphia, St. Louis, and Pittsburgh—within 2026, alongside a planned commercial entry into London by Q4 2026[1][4]. Historical precedents from Waymo’s accelerated 2025–2026 rollout, where it simultaneously opened four new cities in February 2026 and added five more by November 2025, demonstrate that the firm treats multi-city launches as routine rather than exceptional, making the 0% probability appear detached from operational reality[2][6].

Traders should monitor Waymo’s official announcements for the Baltimore, Philadelphia, St. Louis, and Pittsburgh launches, which the company has targeted for 2026, as well as the commercial timeline for London, where testing began in April 2026 with a full launch expected later this year[1][4]. Key dependencies include the validation of self-driving technology in these new geographies and the completion of regulatory approvals in the UK, which Waymo has stated must be secured before offering autonomous rides in 2026[1]. Recent reports confirm Waymo is delivering roughly 500,000 paid rides weekly across its existing network, underscoring the operational capacity to support rapid expansion, while partnerships with Uber and Lyft facilitate access in cities like Austin and Nashville, further lowering barriers to entry[1][3]. The settlement window ending 30 June 2026 leaves ample time for at least two of the targeted US cities to open, rendering the current 0% pricing highly improbable for any outcome where expansion occurs.
