If it's true that Musk is getting rules changes so that SpaceX can be included in the S&P earlier than the current rules allow, I think there's a non-zero chance of Musk falling even more out of favor than he currently is, if not worse (if the SpaceX IPO ends up losing people money in the first 1-2 years)
The hype train will ensure the SpaceX IPO is successful beyond the 2nd year mark. Musk keeps making these moves because he knows, he doesn’t want it catching up to him. Better to offload the risk to Wall Street.
