Waymo, Zoox, Tesla: Who Wins the Robotaxi Race?
Wall Street Week
· · 11 min · Guests: Aicha Evans, David Risher, Sarfraz Maredia, Sergei Kirillov, Mark Fagan
Summary
The episode argues that 2026 may be the year robotaxis move from novelty to broader commercial rollout, but not in a sudden, hockey-stick way. The host says global autonomous activity is concentrated in China and a handful of U.S. cities, with the fleet set to more than double to 18,000 vehicles this year from 8,000 in 2025. Harvard’s Mark Fagan cautions that growth will be gradual, while the host frames robotaxis as on-demand autonomous ride-hailing rather than fixed-route transit.
Waymo is presented as the current U.S. leader because it already runs fully driverless paid rides without a safety driver and plans broader public launches across America in 2026. Zoox’s Aicha Evans makes the case for building a purpose-built vehicle and operating model from scratch, even though she acknowledges it is slower, harder and capital-intensive. Tesla is described as pursuing a three-part robotaxi strategy that includes a cybercab, used Teslas and privately owned cars.
Several speakers emphasize that the key challenge is economics, not just technology. Uber’s Sarfraz Maredia says today’s rides are not competitive on price and that lower vehicle and compute costs will take years. Lyft’s David Risher and Avride’s Sergei Kirillov both argue that partnerships will matter, because ride-hailing platforms, autonomous systems and human drivers are likely to coexist rather than fully replace one another.
Key takeaways
- The host says the global robotaxi fleet should more than double to 18,000 vehicles in 2026 from 8,000 in 2025.
- Mark Fagan expects growth, but not a 'hockey stick' year with 20 cities and 25% to 50% of ride-hail rides automated.
- Waymo is the only company currently running fully driverless paid robotaxi services in the U.S. without a safety driver.
- Aicha Evans says Zoox chose a from-scratch vehicle and operating stack because it should be easier and more ubiquitous at scale.
- Sarfraz Maredia says today’s autonomous ride economics are not competitive and likely need several years of cost declines.
- David Risher and Sergei Kirillov both argue that robotaxis will likely complement, not fully replace, human drivers and existing ride-hailing networks.
Notable quotes
“-If I just zoom out today in 2026, most of the autonomous activity in the world is happening in China and in a handful of cities in the U.S”
“This is not going to be a year in which we see 20 cities with 25 to 50 percent of ride-hail rides being in robo-taxis”
“Right now, Waymo is the only company running fully driverless paid robo-taxi services in the U.S. without a safety driver”
“-It's going to cost a lot. No question about it. This is a capital-intensive endeavor, but I think the returns are going to surprise people”
“If we were to price those rides, or any of our competitors were to price those rides, sort of to break even, they really would not be competitive”
How the episode opens
-Is 2026 the year of the robo-taxi? -I would say 2026 is the year of the Zoox robo-taxi. -I think it's going to be in 2026 where this really starts to take off.
-If I just zoom out today in 2026, most of the autonomous activity in the world is happening in China and in a handful of cities in the U.S. -You are here. -It's the buzziest topic in Silicon Valley, and the public is going crazy for it.
It's a new experience. I'm looking forward to it. It's a new experience.
I'm looking forward to it. -But enthusiasm alone isn't enough to get us to a robo-taxi world. Six years ago, Elon Musk confidently predicted he'd have one million self-driving Teslas on the road by 2020.
One of many predictions that proved to be too optimistic. After hearing that robo-taxis are here for several years in a row, we're told 2026 will be the year of the robo-taxi. The number of vehicles on the road is set to more than double to 18,000 this year, from 8,000 in 2025.
For our purposes, a robo-taxi means on-demand, point-to-point autonomous ride-hailing. It's dynamic and not fixed route. -We will continue to see a growth in autonomous taxis in 2026.
It will not be a dramatic change. -Mark Fagan is a lecturer at Harvard University's Kennedy School. He also runs an autonomous vehicle lab.
This is not going to be a year in which we see 20 cities with 25 to 50 percent of ride-hail rides being in robo-taxis. It's all coming, but I don't believe it is a hockey stick. -For a nascent industry and business without much of a track record, there were already many players.
Waymo, owned by Google-parent Alphabet, takes existing cars and retrofits them with its self-driving system.
