TL;DR — Waymo grew from 10 US metro areas in March 2026 to 15 by August, adding Denver, Las Vegas, San Diego and Tampa. Weekly paid trips stayed at roughly 500,000 across four public disclosures since March, and trips per vehicle fell 25% as the fleet grew faster than ridership. Uber, meanwhile, is winding down Waymo’s exclusivity in cities like Phoenix and diversifying toward a dozen other robotaxi partners with more than $10 billion pledged.
Waymo operated in 10 U.S. metro areas as of late March 2026. By August, it was in 15, after Denver, Las Vegas, San Diego and Tampa all went fully driverless inside a single month. That’s real, fast geographic expansion. What didn’t expand alongside it: weekly paid trips, which have sat at roughly 500,000 across four separate public disclosures since late March — the same number, five more cities, and a materially larger fleet.
Coverage Grew. Utilization Didn’t.
The clearest way to see the gap is trips per vehicle. In May 2025, Waymo’s fleet averaged 167 trips per vehicle per week. By August 2026, with the fleet approaching 4,000 vehicles, that had fallen to roughly 125 trips per vehicle — a 25% decline. Third Pole covered the financial side of this when Waymo’s $126 billion valuation met a $1.8 billion quarterly loss on $382 million of revenue. The ridership data adds a specific mechanism to that loss: Waymo is adding cities and vehicles faster than it’s adding riders, which is a materially different story than a company simply scaling demand it already has.
And Uber Is Quietly Diversifying Away
Waymo’s position on Uber’s app has also started to change. The two companies let their Phoenix pilot — “an intentionally limited deployment” of just over a dozen vehicles — run out its contracted term in May 2026 and end, with Waymo folding those vehicles back into its own app-only fleet. Uber and Waymo are also ending exclusivity arrangements in Atlanta and Austin, where Waymo vehicles have until now been available exclusively through Uber’s app.
None of this is Waymo losing access to Uber’s platform entirely — CEO Dara Khosrowshahi called Waymo a “very, very important partner” even while announcing the wind-down. But Uber has simultaneously pledged more than $10 billion toward a much broader robotaxi portfolio: stakes and vehicle-supply deals with Lucid, Rivian, WeRide, Baidu, Wayve, Momenta, Pony.ai, Zoox, Motional and several others, spanning passenger rides, freight and delivery. Waymo is going from Uber’s flagship exclusive partner to one of more than a dozen options on the same app.
- City coverage: 10 metros in March 2026 → 15 by August — genuine, fast expansion.
- Weekly rides: roughly 500,000, unchanged across four disclosures since March.
- Trips per vehicle: down 25%, from 167 to about 125 a week, as the fleet outgrew demand.
Waymo is buying map coverage, not ride volume. Those are different products, and only one of them shows up in the weekly ridership number.
None of this means the robotaxi bet is failing — Waymo remains the operational leader by a wide margin over rivals like Tesla’s still-nascent robotaxi rollout, which had logged roughly 2.4 million cumulative paid miles by the same point. But a company adding five cities without adding riders, while losing its exclusive perch on the largest ride-hailing app in the U.S., is a different story than the one its city-count headlines tell on their own.
The next data point to watch isn’t another city launch. It’s whether weekly rides finally move off 500,000 now that Waymo has fully driverless service in 15 metro areas — or whether the plateau holds even as coverage keeps expanding.
