Forecast made 15 Oct 2026 · Methodology v2.1

Driverless cars currently provide well under 1% of Uber's rides worldwide, and Uber's own chief executive says a robot majority is 15 to 20 years away. A majority by 2031 would take roughly a million driverless cars on Uber, including in Brazil and India. Only about 120,000 have been promised so far. What would most change this forecast is Uber reporting driverless rides growing several-fold every year across many countries.

Where things stand (mid-October 2026)

Driverless trips are a tiny share of Uber's volume. In Q2 2026, Uber completed 3,867 million trips across Mobility and Delivery, about 42.5 million a day. Uber does not report Mobility trips separately; I assumed they are 65–80% of the total, roughly 28–34 million rides a day. AVs were live on Uber in only 7 cities (Q2 2026 prepared remarks), with up to 15 planned by year-end. Uber has never published an AV share of trips. Its Q1 2026 remarks gave only a growth rate: AV Mobility trips up more than 10x year over year. An analyst newsletter put AVs at under 0.5% of trips after Q2 2026; my own estimate is about 0.1–0.2%. Several of Uber's AV services still carry safety drivers, and those rides would not count here. Wayve in London, for example, launched with a licensed human driver on board. The next qualifying report is Q3 2026 results on 4 November 2026.

Uber's main supplier of driverless rides is pulling back. Waymo has about 4,000 vehicles and roughly 500,000 paid rides a week, mostly booked through its own app (TechCrunch, 24 Sep 2026). That is about 71,000 a day, under 0.3% of Uber's Mobility rides even if every one ran on Uber. Waymo ended its Uber arrangement in Phoenix in 2026 and plans its own app in Austin and Atlanta from January 2028 (Automotive News, 27 Jul 2026). Across all partners, about 120,000 vehicles have been committed to Uber "over the coming years."

Uber's own leaders put a driverless majority 15–20 years away. CEO Dara Khosrowshahi said in February 2026 that most trips being done by robots is "probably not 10 years from now, but… 15 to 20 years." Uber's Q4 2025 AV Spotlight says that over the next 5–10 years it expects to serve suburbs and smaller towns "primarily with human drivers." It also says regulatory reform in New York, Boston and Chicago will take years. By trip count, India and Brazil are among Uber's three largest markets, and Brazil is the largest. Much of that volume is two-wheeler Moto rides and low-cost car rides, which are unlikely to be driverless by 2031.

Scale needed (my own calculation)

I worked from the Q2 2026 trip count, assuming Mobility is 65–80% of trips and grows 10–15% a year. On that basis, Uber's Mobility rides would be about 45–68 million a day by Q3 2031. A majority would mean more than 22–34 million driverless rides a day. At the 25–30 rides per vehicle per day that Uber cites, that needs roughly 0.75–1.4 million driverless vehicles on Uber's network, running across many countries. That is about 10 times all vehicles committed to Uber so far, and over 100 times Waymo's current fleet. Starting from a 0.1–0.5% share, the AV share would have to grow about 2.4–3.3x every year until 2031. Q3 2031 results (about November 2031) are the last report that falls inside the window.

Reference class and forecast

I found no comparable case of a ride-hailing platform's supply switching to a new technology for a majority of trips within five years. Robotaxi forecasts are far more modest: Goldman Sachs projected robotaxis would take about 8% of the US market by 2030, and Uber's own executives give 15–20 years. My estimate of the real-world chance is well under 0.1%. On top of that I add:

  • a small allowance for a sudden technology-driven acceleration, if AI progress sharply speeds up both building and approving AVs;
  • a small allowance for a resolution mistake, such as counting an Uber claim about a majority within certain cities or AV zones, which the rules exclude.

I spread these as a per-quarter chance of about 0.01% through 2028, rising to 0.04% a quarter in 2031. That gives a cumulative 0.45% by the end of 2031.

Strongest case for YES: AV trips on Uber grew more than 10x in a year. Uber has committed over $10 billion and has 30+ partners. Tesla is scaling its Cybercab. Fast AI progress could compress timelines. These do not move me much. Ten-fold growth from a base of about 0.1% cannot hold for five straight years, because vehicle supply, depots, insurance and country-by-country permits limit how fast fleets can grow. Uber's highest-volume markets also have the weakest economic case for replacing drivers, and the biggest AV operators are building their own apps rather than relying on Uber.

Resolution criteria

Opened 16 Sep 2026Not yet resolved

Question. By the last day of each quarter, has Uber reported that vehicles with no human driver provided a majority of its Mobility trips worldwide in any quarter?

Definitions.

  • Uber: Uber Technologies, Inc. and its consolidated operations, including a successor continuing its Mobility business.
  • Mobility trips worldwide: all completed consumer Mobility rides on Uber's platform across all countries where it operates, counted on Uber's reported trip basis. This is the Mobility component of the Trips metric defined under “Key Terms for Our Key Metrics” in Uber's second-quarter 2026 results, not the combined Mobility-and-Delivery total. Shared rides follow Uber's consumer-trip counting convention rather than vehicle journeys. Delivery orders and Freight movements are excluded. Partner-operated rides count if included in Uber's Mobility trips; partners' off-platform rides do not.
  • Vehicles with no human driver: vehicles that perform the entire passenger trip through automated driving, without an onboard human driver or onboard safety driver responsible for taking over driving. Remote monitoring or assistance with routing is permitted, but trips involving remote human steering, braking, or acceleration are excluded. A non-driving attendant does not disqualify a trip. An “autonomous” or “AV” label alone is insufficient if the reported category includes supervised rides.
  • Majority: strictly more than 50% by number of trips, not revenue, Gross Bookings, miles, fleet size, or operating hours. Numerator and denominator must cover the same period and worldwide business scope.
  • Quarter: a complete calendar quarter or a complete fiscal quarter used in Uber's financial reporting, not a quarter-to-date period or arbitrary rolling three-month window.

Resolves YES if Uber reports an actual worldwide driverless Mobility trip share above 50% for a qualifying quarter, explicitly states that such trips constituted a majority, or publishes trip counts establishing that result by arithmetic. A reported estimate of the actual completed-quarter share counts; a target or forecast does not. A range qualifies only if its lower bound exceeds 50%; “about half,” exactly 50%, and rounded counts that do not establish a share above 50% do not qualify. A revised figure may establish YES, subject to the Observation period convention.

Resolves NO if no qualifying report has been published by the horizon. A majority in selected cities, countries, service categories, or only markets with AV availability does not count. Neither annual averages nor an end-of-quarter daily or weekly run rate establishes a quarterly majority. Supervised autonomous rides, including services with an onboard safety driver, do not count toward the numerator.

Resolving source. Uber-authored sources only: SEC Forms 10-Q, 10-K, or 8-K and their exhibits; quarterly earnings releases, presentations, prepared remarks, or Uber-published earnings-call recordings or transcripts at Uber Investor Relations; and official statements on uber.com. This is a narrower source requirement than Public confirmation (A2); third-party estimates, partner disclosures alone, interviews, and press paraphrases do not resolve the question. Apply Resolution date (A3), Resolution window, and Observation period conventions.
