When you are investor and broadly choose to buy US companies (which is what most people do), you get Tesla in the list (e.g. QQQ) as part of the package, and this pushes price higher, no matter if you believe in Tesla specifically or not.

In addition, existing investors are very very deep into Tesla now, and don't want to lose.

The sandcastle is quite fragile so one of the best strategy for everyone (funds and Musk) is to keep buying more, no matter if the news are bad or not. It works, until other people disagree with you, but so far, nobody is interested into losing that game.

I actually short Tesla just enough to offset my long positions that come as part of my regular ETFs.
