Uber Technologies and Rivian Automotive unveiled a transformative autonomous vehicle collaboration on Thursday. The arrangement calls for Uber to pour up to $1.25 billion into Rivian while integrating as many as 50,000 self-driving cars into its mobility ecosystem by 2031.
$UBER and Rivian $RIVN are partnering to deploy up to 50,000 autonomous robotaxis, with San Francisco and Miami targeted for the first commercial launches in 2028.

Shares of Rivian climbed roughly 8% in early premarket activity following the announcement. The gain provides some relief for investors, as the stock had declined over 14% year-to-date prior to this development.
Meanwhile, Uber’s shares showed minimal movement after the partnership was revealed.
The agreement kicks off with a $300 million equity infusion immediately following execution, pending standard regulatory approvals. This translates to approximately 19.55 million shares of Rivian common stock.
Additional funding will be distributed across four separate tranches through 2031, each contingent upon achieving predetermined operational milestones.
Uber—either directly or through fleet operators—commits to purchasing 10,000 autonomous-enabled versions of Rivian’s forthcoming R2 model. An additional purchase option exists for up to 40,000 robotaxis beginning in 2030.
Consumer sales of the R2 are scheduled to commence this spring. Rivian has been systematically advancing its self-driving capabilities, highlighted by its inaugural “Autonomy and AI Day” event held in December.
Deployment Strategy
The autonomous fleet will function exclusively within Uber’s ride-sharing and logistics network. Initial operations begin in San Francisco and Miami during 2028, with subsequent rollout planned for 25 cities spanning the United States, Canada, and European markets.
Uber CEO Dara Khosrowshahi emphasized Rivian’s comprehensive vertical integration—encompassing vehicle design, computing architecture, and software development—as a crucial factor in selecting this partnership.
Rivian CEO RJ Scaringe highlighted the company’s proprietary inference engine, designated RAP1, along with its advanced multi-modal sensing technology as catalysts for accelerated autonomy development.
Uber has also committed to recurring licensing payments for access to Rivian’s self-driving technology platform, according to Thursday’s regulatory disclosure.
Financial Context for Rivian
This agreement represents the latest in a series of significant capital arrangements for Rivian. Toward the end of 2024, the automaker finalized a $5.8 billion software partnership with Volkswagen.
For Uber, this deal extends a pattern of autonomous vehicle collaborations. Recent partnerships include arrangements with Lucid, Amazon’s Zoox division, Stellantis, and Nvidia.
Waymo, supported by Alphabet, currently dominates the American robotaxi landscape. Rivian’s R2 architecture is being strategically positioned to compete directly in this emerging sector.
During Rivian’s third-quarter 2025 earnings discussion, Scaringe emphasized that artificial intelligence advancements and enhanced processing capabilities are the critical enablers for economically viable autonomous taxi services.
This partnership represents Rivian’s most substantial commercial robotaxi initiative yet, with Uber furnishing both financial backing and immediate market access through its established platform.
