Right now it’s easily double to triple that, even with Musks behavior.
I suspect a significant proportion of Tesla's stock price comes from people who are using it as a proxy for his other companies that the public can't invest in, primarily xAI (as all AI companies are in a horrific bubble right now) and SpaceX.
The passive investing / market cap weighted ETF complex tends to help big valuations stay big, but a company like Tesla still needs that sharp shot in the arm followed by frenzied buying occasionally in order to stay aloft (be it by traders, retail participants, shorts covering, etc).
I suppose they could replace Musk with another hype salesman, but the "hate" that Tesla gets is a big part of these upside shock cycles for the stock, because the ticker is a siren call for short sellers, who are ultimately guaranteed future buyers.
I guess it really does depend on which reality distortion field we’re talking about haha.
