It doesn't have to make sense, market cap is a flimsy meaningless value... If everyone holding TSLA tried selling at this price, a small fraction would manage to execute orders at that price before it plummetted.
The thing that doesn't make sense is treating (number of shares * last executed order price) as anything more than just that.
