Uber’s AV Deployment Claim Appears Overstated

Executive Signal Summary

The newsletter critiques Uber’s CFO claim that Uber will operate the world’s largest autonomous-vehicle (AV) fleet by 2029. It highlights Uber’s recent $1.25 billion deal with Rivian to deploy up to 50,000 R2 robotaxis by 2031, but argues many partners lack Level 4 capability and that Waymo’s current scale and backlog (including a reported 50,000-unit Hyundai order and $16 billion in funding) make Uber’s target unlikely. The author estimates Uber’s global AV fleet may reach ~28,000 vehicles by 2029 versus Waymo’s expected ~50,000 by 2028. The newsletter also reports Amazon is again developing a phone (AI/Prime-integrated or simplified “dumbphone”), and raises national-security concerns about widespread AI-generated deepfakes—“The Sloppening”—amplified on platforms like X and reaching large audiences.

Uber Bets Big on Rivian: 50,000 Robotaxis by 2031!

Uber Technologies will invest up to $1.25 billion in Rivian Automotive as part of a deal to deploy up to 50,000 Rivian robotaxis across the U.S., Canada and Europe by 2031. The agreement includes an initial $300 million equity investment expected soon (subject to regulatory approval) and contemplates Uber or its fleet partners purchasing 10,000 autonomous versions of Rivian's R2, with an option to buy up to 40,000 more beginning in 2030. Rivian said additional investment tranches will vest against milestones through 2031. The R2 robotaxis are planned to be exclusive to Uber’s ride-hailing and delivery platform in 25 cities, with San Francisco and Miami targeted as first launch cities in 2028. Uber will also pay licensing fees to use Rivian’s autonomous driving software.
