Demand has surged for Rivian’s R1T pickup trucks, which it began making in September.
The company is loss-making and had delivered less than 200 vehicles as of the end of last month, but its value nonetheless soared it its November 10 stock market debut, topping those of traditional automakers General Motors and Ford.
Rivian was worth $114 billion at the close on Friday, compared with Ford’s $77 billion.
Much of the enthusiasm was fueled by the start-up’s partnerships with Ford and with Amazon, which plans to buy 100,000 Rivian vans by 2030.

Ford however has stepped up its own electric vehicle plans, announcing it would invest $30 billion by 2025 in the cars.
