Rivian's R2 SUV was its best-selling vehicle in the third quarter, with the company raising its delivery guidance for the year to 67,000 vehicles, up from a previous estimate of 65,000 to 70,000. The R2 was launched in June and has seen significant sales, with the company building 19,751 vehicles and delivering 19,248 in the third quarter, a 45% increase from the same period last year. The company had previously struggled to ship more than 50,000 vehicles annually, and the success of the R2 is seen as a sign that Rivian is finding new customers despite the loss of the $7,500 federal EV tax credit and changes to U.S. regulations that supported the growth of EVs.

DoorDash has agreed to acquire Instacart for $17 billion, combining their on-demand delivery services to offer a wider range of products, including restaurant takeout and grocery delivery. DoorDash will pay $65 per share for Instacart, and the deal has been approved by both companies' boards. The acquisition is expected to create new opportunities for retailers and brands to build out their online ordering platforms and advertising businesses using Instacart's technology. DoorDash plans to keep Instacart's brand, technology, and app, and the two companies will continue to operate separately until the transaction closes.
