Shares of Rivian were off roughly 3% during the hourlong event, as many Wall Street analysts believed the stock’s price had already benefited from expectations of the company’s announcements. The stock decline accelerated after OpenAI made its own AI announcement<\/a> Thursday, revealing its most advanced model yet.<\/p>\n Rivian also said it plans to roll out an Autonomy+ subscription with “continuously expanding capabilities” to customers of its second-generation vehicles in early 2026, to be powered by its Rivian Autonomy Processors and autonomy computers. <\/p>\n The Autonomy+ offering will be priced at $2,500 as a one-time upfront purchase or is available for $49.99 per month to start. By comparison, competitor Tesla<\/a> offers its premium FSD (Supervised) option for $8,000 upfront or a $99 per month fee. <\/p>\n “AI is enabling us to create technology and customer experiences at a rate that is completely different from what we’ve seen in the past,” Rivian founder and CEO RJ Scaringe said during the hourlong event.<\/p>\n Company executives said in a statement that a near-future software update will include a “Universal Hands-Free,” capability, allowing Rivian customers “hands-free driving” on over 3.5 million miles of roads in North America, covering the vast majority of marked roads in the U.S.<\/p>\n Rivian CEO RJ Scaringe at the company’s first “Autonomy and AI Day” on Dec. 11, 2025, in Palo Alto, California.<\/p>\n Lora Kolodny | CNBC<\/p>\n Scaringe said the new advanced driver-assistance system will continue to improve as more miles are driven, learning through a data flywheel through reinforced learning.<\/p>\n Unlike its primary competitor, Tesla, Rivian said it intends to use lidar, or light detection and ranging,<\/a>\u00a0systems and radar sensors in its forthcoming “R2” cars to enable “level 4,” or fully automated driving, as defined by SAE Levels of Driving Automation.<\/p>\n A passenger can sleep in the back seat in a level 4 self-driving car while it carries them to their destination in normal traffic and weather conditions. Waymo, the Alphabet<\/a>-owned robotaxi leader in the U.S., considers its vehicles level 4. <\/p>\n Scaringe said Thursday the company’s forthcoming self-driving vehicles enable the company to pursue robotaxis, which Tesla has promised for years but has yet to launch.<\/p>\n “Now, while our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space,” Scaringe said during the event.<\/p>\n Stock Chart IconStock chart icon Rivian and Tesla stock’s since Rivian went public. <\/p>\n Rivian is not alone in aiming to deliver autonomous systems that meet level 4 expectations, while rolling out partially automated features along the way to drivers who generally want these to reduce fatigue on long drives or make them safer behind the wheel overall. <\/p>\n Tesla and General Motors<\/a> are working on their own proprietary driverless systems, while Honda<\/a>, Lucid<\/a> and Nissan have partnered with venture-backed autonomous vehicle tech startups (Helm.AI, Nuro and Wayve respectively) to develop similar systems with a range of different technical approaches.<\/p>\n Powering Rivian’s self-driving aspirations will be a new in-house chip developed by the company, which\u00a0is\u00a0set to launch in 2026. Vidya Rajagopalan, Rivian vice president of electrical hardware, said the chip uses “multi-chip module” packaging and has “high memory bandwidth,” which is “key for AI applications.” Rivian’s chip boasts bandwidth of 205 gigabytes per second.<\/p>\n “Rivian is uniquely positioned to move from a software-defined vehicle and bring to the world an AI-defined vehicle,” Rivian Chief Software Officer Wassym Bensaid said.<\/p>\n The automaker also announced a new AI-powered “Rivian Assistant,” a next-generation voice interface launching in early 2026 on its first- and second-generation vehicles.<\/p>\n Rivian is under pressure to prove its future growth potential to investors<\/a> and to grow its customer base amid slowing sales of battery electric vehicles in the U.S. and competition from Chinese EV makers internationally. <\/p>\n![\"hide](\"https:\/\/static-redesign.cnbcfm.com\/dist\/a54b41835a8b60db28c2.svg\")
