Shares in Rivian Automotive are set to trade publicly Wednesday, and the world should get a better idea of just how excited investors are about the electric vehicle market.

Ahead of the start of trading, Rivian shares priced at $78, which gives the company an estimated market value of $66.5 billion. It's a noteworthy figure, given that Rivian has so far delivered about 150 of its electric pickup trucks to customers, mostly employees, and lost $1 billion in the first six months of this year. The valuation is up there with established automakers such as Honda ($53 billion) and Ford ($80 billion), which sell millions of cars worldwide each year.
