Rivian Shares Rise After First Autonomy & AI Day Unveils In-House Processor

Rivian Automotive, Inc. (RIVN) saw its stock climb 15.89% to $19.04 as of 9:54 AM EST on December 12, 2025, rebounding strongly from the previous day’s decline following the company’s inaugural Autonomy & AI Day event.

The electric vehicle manufacturer unveiled ambitious plans for autonomous driving technology, including a proprietary AI chip and subscription-based self-driving features set to launch in early 2026.

The positive market response reflects growing investor confidence in Rivian’s technological capabilities and long-term growth potential in the competitive EV and autonomous vehicle sectors.

Rivian Debuts Custom Autonomy Processor and AI Driving Stack

At its first Autonomy & AI Day held in Palo Alto, California on December 11, 2025, Rivian announced the development of its proprietary Rivian Autonomy Processor (RAP1), a custom chip designed specifically for vision-centric artificial intelligence applications.

The chip features multi-chip module packaging with high memory bandwidth of 205 gigabytes per second and can process 5 billion pixels per second, positioning Rivian to compete directly with Tesla and other autonomous vehicle leaders. CEO RJ Scaringe emphasized that AI is enabling the company to create technology and customer experiences at an unprecedented rate.

The company plans to roll out its Autonomy+ subscription service in early 2026 for second-generation vehicles, priced at $2,500 upfront or $49.99 monthly. Unlike Tesla’s camera-only approach, Rivian’s system will incorporate lidar sensors, radar, and its custom autonomy computer to achieve Level 4 autonomous driving capabilities, where passengers can safely disengage from driving duties in normal conditions.

A near-future software update will introduce “Universal Hands-Free” capability, enabling hands-free driving on over 3.5 million miles of marked roads across North America.

Market Response Lifts Rivian Shares After AI Announcements

As of 9:54 AM EST on December 12, 2025, Rivian’s stock traded at $19.04, marking a 52-week high of $18.75 and reflecting a year-to-date return of 39.51%. The stock’s market capitalization stands at $22.747 billion, with revenue growth of 28.21% over the last twelve months reaching $5.83 billion.

Despite facing profitability challenges with an EBITDA of -$2.61 billion, the company maintains a healthy current ratio of 2.71 and substantial cash reserves of $7.09 billion, providing financial stability as it scales production.

The market’s positive response to Rivian’s AI announcements comes at a critical time for the company, which faces pressure to demonstrate growth potential amid slowing EV sales in the U.S. and increased competition from Chinese manufacturers. Analyst opinions remain mixed, with price targets ranging from $10 to $25, though firms like Needham raised their target to $23 citing confidence in Rivian’s software and AI capabilities.

The company’s strategic shift toward autonomous technology, separate from its $5.8 billion joint venture with Volkswagen, positions it to pursue both consumer vehicle sales and potential robotaxi opportunities in the future.
