I'm pretty confident the market is acting irrationally and the stock price will drop again once people start to think about Elon's statements and how they're too vague and don't make a lot of sense. The 10-Q next week should bring a lot of that enthusiasm back down to Earth.
The problem with Tesla being an AI company is that it still has to pay for all those gigafactories and vertical integration capabilities, so if Elon is lying again and deliveries are actually down YoY, then those fixed costs make each vehicle more expensive and less profitable and they could get into cashflow trouble before Robotaxis/Cybercabs are profitable. (And that's not taking into account that Tesla would suddenly be responsible for every accident their owned assets cause or that human passengers might take years before accepting being driven around without a human driver).
