Its worth more that gm, ford, Chrysler, and toyota combined. I am not sure what year they will make more cars, revenue, and profit than all those companies combined.
That includes: VW, Porsche, GM, Ford, Daimler, BMW, Toyota, Fiat Chrysler, Honda, Hyundai, Nissan Renault, PSA, Suzuki. Combined.
Regardless of however long the ongoing stock market mania lasts, it's obviously going to obliterate a large number of shareholders on the way back down. There is no scenario where Tesla can fill in even a modest amount of that market cap.
Toyota is their absolute most extreme best case scenario. Toyota is worth less than 1/2 what Tesla is today. It would take decades for Tesla to get as large and profitable as Toyota if everything works out perfectly.
So while they sell cars and that is the majority of what they are known for now... it’s believed in the future they will be worth more because of the AI and storage businesses
I think at this point the only Automaker that can follow up Tesla could be Toyota or VW.
