# Uber Stock After Q3 2026 Earnings: Robotaxis Do More Trips on Uber's App — InvestMoat Research

_Uber's CFO says robotaxis on its network do about twice the daily trips of Waymo's and Tesla's new solo launches. I think that gap is the price of going it alone, and Uber's Mobility margin, up as it cut rider spending, is how to check it._

## Summary

On its Q3 2026 call Uber's CFO said robotaxis on its network in mixed markets do trips per vehicle per day in the high twenties, against the low teens for Waymo's and Tesla's own 2026 launches, and about 30% more than mature solo fleets. I think that utilization gap is Uber's network effect carrying into autonomy. Mobility revenue fell 2% on bookings up 18%, mostly because Uber now counts only its cut as revenue in some markets. Mobility segment operating income rose 27%, and as a share of bookings reached 8.0% against 7.4% a year earlier, after Uber cut rider incentives. The case against is that the utilization figures are Uber's own, Waymo is leaving the hybrid model it criticises, and a rising margin on slowing growth is also what harvesting looks like.

## What would prove this wrong

If Uber's Mobility segment operating income falls below 7.4% of Mobility gross bookings (to one decimal) in any quarter from Q4 2026 through Q4 2027, or Mobility gross bookings growth runs below 15% in constant currency for two straight quarters in that span while the margin holds, or Uber gives no numbered robotaxi utilization comparison on its Q4 2027 call (about February 2028), then the network is paying for riders, harvesting, or losing its place in autonomy, and I'm wrong.

_Status as of November 8, 2026: **holding**._

Mobility revenue, Q3 2026: -2% YoY · Mobility profit as % of bookings: 8.0% · Robotaxi trips per vehicle per day: High 20s vs low teens · UBER price: (live)

Uber's CFO said something on the Q3 2026 call that goes straight at the biggest worry about the stock. Asked about robotaxis, Balaji Krishnamurthy said Waymo and Tesla cars in the markets they launched on their own this year do trips per vehicle per day "in the low teens." Autonomous cars on Uber's network, in markets that mix robots and human drivers, do "high twenties." The bear case on Uber is that robotaxi operators won't need it. **I think that gap is the price of going it alone, and it's the best evidence yet that Uber's network carries into autonomy.**

You may have seen that Mobility revenue fell 2% while Mobility bookings, the total fares riders paid, rose 18%. That's mostly bookkeeping. Since Q1 2026 Uber has counted only its own cut as revenue in some markets, instead of the whole fare, which shrinks revenue without changing what riders spend. Profit is the better test, and I'll get to it after the robotaxi numbers.

## The robotaxi numbers from the call

A robotaxi costs about the same whether it carries riders or sits empty, so trips per car per day decide whether it makes money. A human driver logs off when demand is thin. A robot sits on the operator's books. That makes a pool of waiting riders worth more with robots than it was with drivers.

**Robotaxi figures Uber gave on its Q3 2026 call. These are management statements, not audited disclosures, and Waymo and Tesla haven't confirmed them.**

| Measure | What Uber said | Who said it |
| --- | --- | --- |
| Trips per vehicle per day, Waymo and Tesla in 2026 own-app launches | Low teens | CFO Balaji Krishnamurthy |
| Trips per vehicle per day, robotaxis on Uber in hybrid markets | High twenties | CFO Balaji Krishnamurthy |
| Utilization premium vs mature own-app deployments in the US | About 30% | CEO and CFO |
| Fully driverless vehicles on Uber | About 700 by end of 2026; over 2,000 by end of 2027 | CEO Dara Khosrowshahi |
| Who funds the fleet | Uber's balance sheet early; third-party capital in the long run | CEO and CFO |

There are two comparisons in that table and they're different sizes. Against Waymo's and Tesla's new solo launches, Uber says its network roughly doubles daily trips. Against mature solo fleets in the US, the edge is about 30%, and Krishnamurthy said that comparison includes San Francisco, a market he called especially good for robotaxis. The smaller number is the one I'd lean on. A 30% edge on a car whose cost is mostly fixed is a lot of margin.

The mechanism is the one that runs the human business. Uber has riders already open on their phones, so it can fill a robot's dead time between trips with demand a single-operator app doesn't have yet. If that holds, the network effect survives the driver leaving. Its job changes from finding drivers to filling cars.

The scale is tiny. Seven hundred driverless cars is nothing next to a business that handled 4.1 billion trips across rides and delivery in Q3. What the quarter gave is the first operating numbers on the question everyone argues about.

## How I'd check it from outside

Utilization figures come from Uber, about rivals who don't report them. The number I can check is how much of each Mobility booking dollar Uber keeps as segment operating income, its profit measure since January 2026. A network losing riders to robotaxi apps has to pay them to stay, and that shows up as a lower share.

**Uber's segment operating income as a share of gross bookings. Mobility stepped up in Q1 2026, the quarter a reporting change began, and again in Q3 2026, the first step that can't be put down to that change.**

| Period | Mobility | Delivery |
| --- | --- | --- |
| Q4 2024 | 7.05% | 3.17% |
| Q1 2025 | 7.49% | 3.29% |
| Q2 2025 | 7.28% | 3.52% |
| Q3 2025 | 7.42% | 3.48% |
| Q4 2025 | 7.39% | 3.56% |
| Q1 2026 | 7.69% | 3.7% |
| Q2 2026 | 7.64% | 3.84% |
| Q3 2026 | 8% | 3.7% |

Q1 2026: Reporting change begins; Q3 2026: First quarter clear of it.

Segment operating income divided by segment gross bookings, my arithmetic from Uber's releases. Q4 2024 to Q3 2025 use Uber's January 2026 recast of segment operating income; later quarters are as reported. Delivery is shown as a comparison: the same gig network, with no robotaxis in the numbers.

Mobility kept 8.0% of bookings in Q3 2026, against 7.4% a year earlier. I have to be careful with the first step up. It came in Q1 2026, the same quarter the reporting change began, and I couldn't confirm from the filings that the change left profit exactly untouched. The step from Q2 to Q3 is the clean one, and CEO Dara Khosrowshahi gave the reason: "we are taking down rider incentives and we are using those dollars to fund driver incentives."

So this year Uber cut what it spends on riders and kept more per booking dollar, in the same year Waymo and Tesla started running their own apps. Delivery, the same gig network with no robots in it, kept more too, so part of this is Uber-wide discipline rather than anything robotaxi-specific. Krishnamurthy put the Q3 slowdown down mainly to driver supply abroad, with fuel costs from the Middle East war hitting Brazil and India hardest, and said US growth moderated less.

For the shares, the debate is whether Mobility is a business robots will route around. If the utilization edge is real, the robotaxi era raises Uber's value as the place fleets go to get filled, and the margin should keep holding as the fleet grows. That's why I've put Uber next to the two operators and next to DoorDash, which runs the same kind of network in delivery and is here as a comparison, not as evidence. My [DoorDash piece](/research/doordash-instacart-and-the-scale-its-network-cant-supply) and [Tesla piece](/research/tesla-and-the-delivery-beat-the-moat-does-not-need) cover their sides.

## The case that Uber is harvesting a slowing network

The strongest objection is that a rising margin and a slowing network look the same in one quarter. Mobility bookings growth slowed in Q3 to 17% in constant currency, from 20% in each of the first two quarters, and Uber chose this year to take money away from riders. If riders are drifting to Waymo where it runs alone, cutting rider spend and booking a higher margin is what a company does when it defends profit instead of share. The margin would rise right up until the volume went.

Waymo has said as much in public. It told Uber in July it plans to launch its own app in Austin and Atlanta in January 2028 ([TNW](https://thenextweb.com/news/waymo-uber-exclusivity-ends-austin-atlanta-robotaxi)), and on November 4, earnings day, co-CEO Tekedra Mawakana told Bloomberg the Uber experience was a "lottery" for riders who can't tell whether a robot or a human will turn up ([Ubergizmo, citing Bloomberg](https://www.ubergizmo.com/2026/11/waymo-end-uber-partnership/)). That goes straight at the hybrid model behind Uber's best number.

The hybrid number has a second weakness. In a mixed market Uber's dispatch decides which trips go to robots. If it sends them the dense, easy rides and leaves the rest to humans, trips per car will look great without telling you much about the network. And the 30% gap against mature fleets is still Uber's comparison of Uber's markets. Neither Waymo nor Tesla has any reason to publish a figure that agrees.

I take all of that seriously, which is why my test pairs the margin with growth. If Uber is harvesting, the margin holds while bookings growth keeps sliding, and I've written that into the claim below. If the network is intact, Uber shouldn't need to buy riders back as Waymo's own app reaches more of its cities. The utilization gap is the claim I'd most like someone outside Uber to confirm, ideally with dispatch mix disclosed.

## What I'm watching

1. February 2027, the Q4 2026 report: Mobility segment operating income as a share of Mobility bookings, last 8.0%. Back below 7.4% and the network is paying to hold riders.
2. Mobility bookings growth in constant currency, last 17%. Two more quarters below 15% with the margin flat or rising would look like harvesting.
3. Whether Uber gives an updated, numbered utilization comparison, and whether Waymo or Tesla ever publish their own trips per vehicle per day.
4. The driverless count against management's 700 by end of 2026 and over 2,000 by end of 2027, and how much of it sits on Uber's balance sheet.
