This also affects the EV startups' funding (as well as self driving startups like Cruise). The main reason EV companies like Rivian and Tesla are worth that much is the cheap R&D money and their promise of future return. Traditional car companies are worth what they are because investors expect them to remain car companies.Most of these news stories are ignoring the elephant in the room: a year ago every new car was wildly expensive, with $10K-$20K over MSRP common. Used cars were similarly high priced, with some going for over MSRP. Interest rates near zero were making those prices look reasonable.
That bubble popped. Pent-up demand was satisfied, manufacturers caught up, and interest rates rose to (almost) historically normal levels. Dealer lots are full, and quiet price cutting has started.
This affected EVs as well as ICE vehicles.
Tesla has about 39% of its value priced in from selling and making cars (from BofA's graph I read somewhere). People are not pricing them like a traditional car company because they aren't a car company, or their stocks won't be worth that much.
