Shares of Rivian climbed roughly 8% during premarket hours following the announcement. The jump 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 in response to the partnership reveal.
The first capital infusion of $300 million will arrive soon after finalization, contingent upon regulatory clearance. This amount translates to approximately 19.55 million shares of Rivian.
An additional four investment stages are scheduled, with each payment dependent on achieving particular performance benchmarks by dates yet to be disclosed through 2031.
The ride-hailing company — either directly or through its fleet operators — will acquire 10,000 self-driving variants of Rivian’s forthcoming R2 model. An option exists to procure up to 40,000 additional autonomous vehicles beginning in 2030.
Consumer sales of the R2 are scheduled to commence this spring. Rivian has been steadily advancing its autonomous capabilities, holding its inaugural “Autonomy and AI Day” event in December.
Deployment Strategy
These autonomous vehicles will function exclusively within Uber’s ride-sharing and delivery ecosystem. Initial operations begin in San Francisco and Miami in 2028, with subsequent rollout planned for 25 metropolitan markets spanning the U.S., Canada, and Europe.
Dara Khosrowshahi, Uber’s CEO, expressed confidence in Rivian’s integrated methodology — combining vehicle engineering, computing infrastructure, and software development under one roof — as a fundamental advantage supporting this partnership.
RJ Scaringe, Rivian’s chief executive, highlighted the company’s proprietary inference platform, known as RAP1, alongside its advanced multi-modal perception technology as catalysts accelerating autonomous development.
According to Thursday’s regulatory disclosure, Uber has also committed to paying licensing fees for utilizing Rivian’s autonomous driving technology.
Rivian’s Financial Momentum
This agreement follows an active period of capital raising for Rivian. Late in 2024, the automaker finalized a $5.8 billion software partnership with Volkswagen.
For Uber, this partnership extends a series of autonomous vehicle initiatives. The company recently announced collaborations with Lucid, Amazon’s Zoox division, Stellantis, and Nvidia.
Alphabet-backed Waymo currently dominates the American robotaxi landscape. Rivian’s R2 platform represents the company’s strategic entry into this competitive sector.
During Rivian’s third-quarter 2025 earnings discussion, Scaringe emphasized that artificial intelligence advancements and enhanced processing capabilities are the critical factors enabling commercially viable robotaxi operations at scale.
This partnership represents Rivian’s most definitive move into the commercial autonomous vehicle market, with Uber delivering both financial backing and immediate market access.
