Is It Time to Buy Rivian After Uber Partnership?

By Geoffrey Seiler – Mar 24, 2026 at 10:47AM ESTKey PointsRivian's newest deal with Uber will help it pursue autonomous driving and robotaxis.The move adds to an already impressive list of partnerships the company has formed. Rivian Automotive (RIVN 1.52%) added to its impressive list of partnerships when it recently struck a deal with ride-share leader Uber Technologies (UBER 2.58%). The deal will help the electric vehicle (EV) maker fund its autonomous driving ambitions. Under the agreement, Uber will invest up to $1.25 billion in Rivian, including $300 million immediately after the deal clears regulatory approval. As part of the agreement, Uber will buy 10,000 autonomous versions of Rivian's R2 vehicles with an option to purchase 40,000 more starting in 2030. The R2 robotaxis will be available exclusively through Uber and are expected to be available in San Francisco and Miami in 2028.

It now looks like it plans to reach full autonomous level 4 driving by 2028, given the deal's timeline. For the R2, the company will use a custom chip called the Rivian Autonomy Processor (RAP1), and it will eventually add a lidar sensor to go along with cameras and radar. As such, it is going after autonomy with a more sensor-rich stack like Alphabet's Waymo, as compared to Tesla, which has been taking a vision-first approach and not using lidar. The agreement follows Rivian's penchant for striking partnerships with leading companies. Amazon became a major stakeholder in the company back in 2019, after it chose Rivian to be its electric delivery van provider. Meanwhile, Rivian formed close ties with Volkswagen back in 2024, as the German automaker agreed to invest up to $5.8 billion in Rivian. The two companies also formed a joint venture that gave Volkswagen access to Rivian's important zonal electrical architecture that can significantly reduce the costs of EVs.

Rivian's software business has been a fast-growing, high-margin part of its business that has helped the company achieve positive gross margins. Now the company is really looking to shift this part of its business into overdrive by going after full autonomous driving and robotaxis in the next few years. I wouldn't be surprised if the company actually has a late-mover advantage with this as it learns from Waymo's and especially Tesla's mistakes. At the same time, Rivian's new R2 vehicle is set to greatly expand the market for the brand's electric SUVs while improving its gross margin profile as it scales up production. The company has a solid reputation in the luxury end of the EV SUV market, so I think it can be successful in the upper middle range as well. Right now, Rivian has a lot of good things going on, which makes the stock a solid speculative buy in my view.Read NextMar 4, 2026 •By Ryan VanzoForget Betting Markets: The Best Prediction You Can Make Right Now Is Buying This AI StockDec 13, 2025 •By Geoffrey SeilerTesla vs. Rivian: Which EV Stock Will Outperform in 2026?Sep 20, 2025 •By Rick OrfordLucid vs. Rivian: Which Is the Better Buy Right Now?Sep 5, 2025 •By Rick OrfordWhere Will Rivian Stock Be in 5 Years?Jun 25, 2025 •By Geoffrey SeilerBetter EV Stock: Rivian vs. TeslaJan 24, 2025 •By Johnny RiceWhy Rivian Stock Plummeted This WeekAbout the AuthorGeoffrey Seiler is a contributing Motley Fool stock market analyst covering technology, consumer goods, healthcare, energy, and materials stocks.
