In a significant development for autonomous mobility, Uber Technologies and Rivian Automotive unveiled a transformative robotaxi collaboration on Thursday. The partnership involves Uber investing as much as $1.25 billion in the electric vehicle manufacturer while committing to deploy up to 50,000 self-driving vehicles across its platform by the end of the decade.
$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 Thursday trading following the announcement. The uptick represents a welcome rebound for the EV maker, whose stock had declined over 14% year-to-date prior to the news.
Meanwhile, Uber’s shares showed minimal movement in response to the partnership reveal.
The agreement calls for an initial $300 million capital infusion immediately following deal finalization, contingent upon regulatory sign-off. This upfront investment translates to approximately 19.55 million Rivian shares at current valuations.
Additional funding will arrive in four subsequent installments, each contingent upon achieving predetermined operational benchmarks at dates yet to be disclosed, extending through 2031.
Under the agreement, Uber—or its affiliated fleet operators—will acquire 10,000 autonomous-ready versions of Rivian’s forthcoming R2 model. An additional option exists to procure up to 40,000 more self-driving units commencing in 2030.
The R2 vehicle is scheduled for consumer availability this spring. Rivian has been steadily advancing its autonomous capabilities, highlighted by its inaugural “Autonomy and AI Day” event held last December.
Deployment Strategy
The autonomous fleet will function exclusively within Uber’s ride-sharing and logistics ecosystem. Initial deployment is scheduled for San Francisco and Miami in 2028, with subsequent rollout planned for 25 metropolitan markets spanning the United States, Canada, and European territories.
Uber’s Chief Executive Dara Khosrowshahi emphasized Rivian’s end-to-end integration strategy—encompassing vehicle architecture, computing infrastructure, and software development—as a primary factor driving confidence in the collaboration.
Rivian CEO RJ Scaringe highlighted the company’s proprietary inference platform, designated RAP1, alongside its advanced multi-modal sensing capabilities as catalysts enabling accelerated autonomous technology development.
According to Thursday’s regulatory disclosure, Uber has also committed to ongoing licensing payments for utilization of Rivian’s autonomous driving technology suite.
Financial Context for Rivian
This agreement arrives amid an active fundraising period for Rivian. Late last year, the automaker finalized a substantial $5.8 billion software partnership with Volkswagen.
For Uber’s part, this partnership represents the latest in a series of autonomous vehicle initiatives. Recent months have seen the company forge alliances with Lucid, Amazon’s Zoox division, Stellantis, and Nvidia.
Alphabet-supported Waymo currently dominates the domestic robotaxi landscape. Rivian’s R2 architecture is being strategically positioned to compete directly in this emerging market segment.
During Rivian’s third-quarter 2025 earnings discussion, Scaringe noted that advancements in artificial intelligence and computational processing power have finally enabled economically viable large-scale robotaxi operations.
The partnership represents Rivian’s most definitive move into commercial autonomous transportation, with Uber furnishing both financial backing and established market access.
