Tesla’s stock surge comes a week after one of Tesla’s leading electric vehicle rivals, Nikola, debuted its stock on public markets. Like Tesla, Nikola is building all-electric vehicles. But there are a couple of big differences. First, while Tesla initially focused on passenger cars, Nikola will initially sell trucks along with off-road vehicles and a jet ski. Second, while Tesla cars run on batteries, Nikola is focusing on fuel cells—though some vehicles will have a battery option.

Nikola’s first week on the stock market has been strong, with the stock price nearly doubling to reach Wednesday’s closing price of $65. This makes Nikola worth nearly $30 billion—on par with Ford—before it has shipped its first vehicle.
