Key Highlights

• Uber commits to investing as much as $1.25 billion in Rivian over the next seven years
• A first installment of $300 million will be made after the agreement closes, subject to regulatory clearance
• Uber intends to acquire 10,000 autonomous R2 vehicles, with the possibility to add 40,000 more beginning in 2030
• The autonomous vehicle service debuts in San Francisco and Miami during 2028, followed by expansion across 25 metropolitan areas in the U.S., Canada, and Europe
• Rivian shares climbed approximately 8% during Thursday’s premarket session

On Thursday, Uber Technologies and Rivian Automotive revealed a groundbreaking robotaxi collaboration. The agreement calls for Uber to pour up to $1.25 billion into Rivian while deploying as many as 50,000 self-driving vehicles on its network by the conclusion of 2031.

Shares of Rivian climbed roughly 8% in early premarket activity following the disclosure. This represents a notable bounce for the stock, which had declined over 14% year-to-date prior to the announcement.

Meanwhile, Uber’s stock showed minimal movement after the partnership was made public.

The opening payment of $300 million is expected soon after finalization of the agreement, contingent upon securing regulatory clearances. This amount translates to approximately 19.55 million shares of Rivian.

An additional four investment installments are scheduled, each contingent upon achieving particular performance targets by dates to be determined through 2031.

Uber — or the fleet operators working with the platform — will acquire 10,000 self-driving variants of Rivian’s forthcoming R2 model. An additional purchase option exists for up to 40,000 additional autonomous vehicles commencing in 2030.

The R2 vehicle is already scheduled to become available to retail customers this spring. Rivian has been advancing its autonomous capabilities, having held its inaugural “Autonomy and AI Day” event in December.

Deployment Strategy

The autonomous fleet will function solely within Uber’s ride-sharing and food delivery ecosystem. Initial operations begin in San Francisco and Miami throughout 2028, with subsequent rollout planned for 25 metropolitan regions spanning the U.S., Canada, and Europe.

Dara Khosrowshahi, Uber’s Chief Executive, expressed strong support for Rivian’s comprehensive vertical integration strategy — encompassing vehicle engineering, computing infrastructure, and autonomous software development — as a critical factor driving confidence in this collaboration.

RJ Scaringe, Rivian’s CEO, highlighted the company’s proprietary inference technology, known as RAP1, along with its advanced multi-modal sensing capabilities as catalysts for accelerated autonomous vehicle development.

Uber has also committed to paying licensing royalties for utilizing Rivian’s self-driving technology, according to a regulatory disclosure filed Thursday.

Rivian’s Financial Landscape

This partnership comes during an active fundraising period for Rivian. Late in 2024, the electric vehicle manufacturer finalized a $5.8 billion technology agreement with Volkswagen.

For Uber, this represents another step in an aggressive autonomous vehicle strategy. The ride-hailing giant has recently unveiled partnerships with Lucid, Amazon’s Zoox division, Stellantis, and Nvidia.

Waymo, supported by Alphabet, presently dominates the American robotaxi landscape. Rivian’s R2 vehicle is being strategically positioned to compete directly in this emerging sector.

During Rivian’s third-quarter 2025 earnings presentation, Scaringe noted that advances in artificial intelligence and enhanced semiconductor capabilities are the breakthrough elements enabling large-scale robotaxi deployment.

This partnership represents Rivian’s most substantial commercial autonomous vehicle initiative announced thus far, with Uber delivering both financial backing and market access.
