Thinking of buying shorts on twitter now with all the dumb ass news going around...
The best you could do is find a prediction market and bet against specific metrics.
I think a drop in Tesla share price would be likely, but I don't see why it would hit freefall?
To give you an idea:
Tesla revenue: 74.86B
Toyota revenue: 260.13B
Tesla market cap: 498.56B
Toyota market cap: 234.96B
That's roughly a 7.4x difference in expectation vs. reality.
I also think that a lot of anti-Musk sentiment has already been priced in. While a Twitter bankruptcy would absolutely have some further impact on that sentiment, it doesn't seem immediately obvious that it would wipeout all of Musk's fanatical support.
Given that, an immediate drop to 13% of Tesla's current value seems like a significant overestimate if Tesla keeps hitting sales and production targets. If Twitter bankruptcy accompanies a significant reduction in Tesla sales, I could see a drop of that size or larger, but not from a Twitter bankruptcy alone.
Tesla however does not sell non-EVs so stands only to gain as the non-EV market shrinks. This makes up some amount of the expectations that give Tesla a higher share price per current revue than other car makers.
Thus even if Musk's "genius magic" effect on stock price goes away complete, that seems unlikey to eliminate all expectations for more growth from Tesla than other car manufacturers.
That said, I think we mostly agree now as I think a drop by 2/3rds in Tesla price is not out of the realms of possibility. It's hard to guage how big the "genius magic" effect is on stock price.
Personally, I suspect that significant issues (especially regulatory) around FSD are more likely to crater the growth expectations of Tesla than any Twitter bankruptcy.
