Arguably
S&P index inclusion has not been politicized or corrupted before AFAIK, and I don't see the S&P starting with that for the sake of Tesla, who is really a small player in the trillions of dollars of index fund flows.
S&P and other ratings agency credit ratings on the other hand was and continues to be a big source of revenue, and with the 'bond issuer pays the credit rating agency' business model there's an
obvious conflict of interest that's not addressed even today.
That conflict of interest does not exist, or is at minimum much, much weaker for the rather mechanic act of S&P 500 inclusion.
So I hope it's going to be mechanic inclusion in ~June.
While it's an exciting movie, I found it kind of disturbing that the protagonist set out to earn a billion dollars from the potential collapse of civilization as we know it. They didn't warn anyone or work towards a solution in reality - they mostly hid all that information they uncovered to try to profit from it privately.
I.e. the usual Hollywood script of "hero sees end of the world and saves it" has changed into "hero sees end of the world and hopes it happens so that he can profit from it financially" script.
While I realize that this is how half of Wall Street is earning money, it's rather obscene if we look at the big picture...
