Austin has become the first city where a car with no steering wheel picks up paying customers. Tesla opened Cybercab rides to the public on September 4, 2026, starting with just 45 registered Cybercabs (Axios). Two months later, Tesla's Texas robotaxi registry has passed Waymo's.
If you work at Tesla, or hold Tesla RSUs from a past grant, this story is important to your net worth. The question that matters for Tesla’s shareholders is not how many cars are on the road. It is how much of each fare Tesla keeps, and for how long they can keep their margins high.
This paper compares the Cybercab with Uber, Lyft, and Waymo on the numbers that drive margin:
Who keeps each fare dollar today, Uber and Lyft versus a driverless fleet.
How many robotaxis Tesla and Waymo run in Austin and across Texas.
What Austin riders pay for a Tesla ride versus a human-driven Uber.
Where fares land if competition squeezes the robotaxi margin.
Why Tesla has reasons to protect that margin for years.
The short version: Tesla removed the most expensive part of a ride, the driver, but has kept prices close to Uber's. The gap between cost and price is worth exploring.
Cybercab Margin vs. Uber and Lyft
At target cost, Cybercab keeps 83 cents per mile.
Start with the human-driven model. In Q3 2026, Uber's ride business booked $29.5 billion and recognized $7.52 billion as revenue, keeping about 25.5 cents of each booking dollar. Its Mobility segment earned $2.36 billion of operating income, about 8 cents per booking dollar (Uber). Lyft booked $5.6 billion, reported $1.8 billion of revenue, and produced $203.9 million of adjusted EBITDA, or 3.6 cents per booking dollar (Lyft). Most of the remaining money flows to driver earnings, incentives, insurance, and fees.
Tesla's CFO said on the Q3 call that the robotaxi goal is $0.30 of operating cost per paid mile, that Tesla is not there yet, and that he sees a path to it through scale (Tesla Q3 2026 earnings call). Huaxing Securities estimates Austin Cybercab rides of 3 to 8 miles currently cost riders $1.50 to $2.00 per mile under dynamic pricing (Gasgoo). Put those side by side and each fare dollar splits very differently:
Uber Mobility: about 74.5 cents to drivers and other pass-through items, 17.5 cents to platform costs, 8 cents of segment profit.
Lyft: about 67.6 cents outside revenue, 28.8 cents to costs, 3.6 cents of adjusted EBITDA.
Cybercab at $1.75 a mile and $0.30 cost: about 17 cents to operating cost, 83 cents left over.
Cybercab at $1.75 a mile and a stress-test cost of $0.60: about 34 cents to cost, 66 cents left over.
The Uber and Lyft figures are calculated from their Q3 2026 filings. The Cybercab lines are our model, and the $0.60 stress case is our assumption, set at double Tesla's target because Tesla says it has not reached $0.30. The "left over" amount is not net profit. It still has to cover any costs outside Tesla's target, such as software development and corporate overhead. Even so, the gap is enormous. Uber earns 8 cents on a dollar of rides. A driverless fleet charging Uber-like prices could keep many times that.
Austin Fleet Count: Tesla vs. Waymo
Tesla passed Waymo's Texas registry quickly.
Waymo arrived first. It began Austin rides through the Uber app in March 2025 and has grown its service area from 37 to 150 square miles (KXAN). Waymo runs roughly 300 vehicles in Austin (Houston Chronicle) and about 4,000 nationally (Los Angeles Times). Tesla's growth since September has been steep. The scoreboard reads like this:
Texas registry, November 10: Tesla 1,302 vehicles (729 Model Y, 573 Cybercab) versus Waymo 1,297 (Business Insider).
Texas registry, end of May: Tesla 42 versus Waymo 619 (same source).
Austin Cybercabs: Tesla claimed 300+ about one month after launch, an eightfold jump (Teslarati).
Austin on the street, mid-October: 354 Tesla robotaxis by independent count, versus 300+ Waymos (CBS Austin).
Weekly Austin miles: Tesla logged 438,000 driverless miles in the week ending October 18, versus Waymo's Q2 average of 406,000 (Electrek).
The Texas registry shows permission to operate, not cars carrying riders, and it says nothing about revenue (Business Insider). The mileage comparison pits Tesla's best week against Waymo's spring average (Electrek). Fair to say the two fleets are now roughly the same size in Austin, with Tesla growing faster.
Austin Fare Quotes: Robotaxi vs. Uber
One five-mile Tesla quote ran $19.58 versus $12.96.
If the margin holds, Tesla will be pricing near human-driven rides rather than far below them. Austin's evidence points that way. Price data from San Francisco, where Tesla rides still carry a safety driver, tells a different story:
Austin, five miles at lunch: a Tesla Robotaxi Model Y was quoted $19.58 against $12.96 for an Uber EV (Detroit Free Press, citing the Austin American-Statesman).
Austin, 2.5 miles after Cybercab launch: Tesla quoted $12.15 with a 40 to 50 minute wait, while Uber priced the trip at $7.96 with under 10 minutes (same source).
Austin Cybercab per mile: $1.50 to $2.00 on 3 to 8 mile trips (Gasgoo).
San Francisco, late 2025: Tesla averaged $8.17 a ride versus Uber at $17.47, Lyft at $15.47, and Waymo at $19.69 (Axios).
San Francisco, spring 2026: Tesla prices rose 41% while remaining the cheapest option (Obi).
The pattern matters. Where Tesla runs driverless, in Austin, it prices at or above Uber. Where it still pays a human in the seat, in San Francisco, it prices low and has been raising fares. A Bank of America analyst said on the Q3 call that Tesla prices below rivals "in most markets" (Tesla Q3 2026 earnings call). Austin's quotes are spot checks, not a full study, so the honest read is that Tesla's driverless pricing sits in Uber's neighborhood, not at the $0.30 to $0.40 per mile Musk floated in 2024 (Yahoo Finance).
Margin Contraction Price Projections
Fares could fall to 40 cents per mile.
Company guidance is biased. A better projection asks where fares settle if rivals force the margin down. here is the math: price per mile equals cost per mile divided by one minus the margin. Using Tesla's $0.30 target cost, with our $0.60 stress cost in parentheses, the scenarios look like this:
Hold today's pricing: about $1.75 a mile, an 83% margin, or $8.75 for five miles.
Margin falls to 50%: $0.60 a mile ($1.20), or $3.00 for five miles ($6.00).
Margin falls to Uber's take: keeping 25.5 cents per dollar gives $0.40 a mile ($0.81), or $2.01 for five miles ($4.03).
Margin falls to Uber's segment profit: keeping 8 cents per dollar gives $0.33 a mile ($0.65), or $1.63 for five miles ($3.26).
These are our projections, not company forecasts, and they exclude taxes, airport fees, and minimum fares. The Uber benchmarks come from its Q3 2026 results (Uber). Scenario three lands almost exactly on Musk's 2024 fare talk, which suggests that number described a mature, fully competitive market. Against Uber's $12.96 quote for five Austin miles, every contraction scenario is a discount of 50% or more for riders. That is the price war Tesla could start, and has chosen not to start yet.
Tesla Pricing Strategy and TSLA RSUs
supply constraint lets Tesla price near Uber.
Several facts suggest Tesla plans to earn a wide margin for some time instead of buying market share with low fares. The supply is short: riders in Austin waited 40 minutes to over an hour for a Cybercab (Detroit Free Press). When demand exceeds cars, cutting price only lengthens the line. The reasons stack up:
Tesla plans to own most Cybercabs and sell rides as a service, so fleet margin is Tesla's margin (Tesla Q3 2026 earnings call).
The CFO expects robotaxi to be a significant part of profitability in 2027, which favors margin over cheap rides (same source).
Cybercab sales to customers are targeted before the end of 2026, and buyers will want fleet returns that support the price (same source).
Waymo's own app arrives in Austin in January 2028, so the strongest competitive pressure is still over a year away (CNBC).
For an equity-compensated professional at Tesla, this cuts both ways. A long runway of high margins supports the robotaxi story behind your RSUs. The same math shows how fast that margin can shrink once Waymo, Uber's partners, and Tesla's own expanding fleet compete for the same rider. A household with most of its wealth in TSLA is betting on margin persistence, whether it means to or not. Knowing which scenario your plan depends on is the first step to sizing that bet on purpose.
If your paycheck and your portfolio both ride on the same robotaxi thesis, it is worth stress-testing your plan against the margin contraction scenarios above. Longitude Financial Planning focuses on making equity compensation simple for Austin professionals, including how much Tesla stock to hold, when to sell RSUs, and how to manage the taxes. A short review can show what happens to your goals if the Cybercab margin holds, and what happens if it doesn't.
