You should short the stock. If you think it’s a big scam and not actually worth being in the top 500 US companies, you could make a lot of money.
It’s an incentive for people to root out corruption and graft. If you truly believe that SpaceX is a big scam and it’s not actually worth enough to be in the S&P 500, then taking a short position not only will net you a bundle of cash, it will do the public a service by helping to expose a fraud and prevent future companies from doing the same thing.
That societal benefit is mostly worthless to investors.
Investors need to capture a good return (risk adjusted) to have any incentive to expose frauds or scams.
But no, we're in the grift economy where I'm suppose to hedge my bets about how big a fraud is and when someone will wake up naked in a pit of aligators.
Good luck with that.
