Summary
The post alleges that upcoming rule changes for both the NASDAQ-100 and S&P 500 indices are designed to facilitate a rapid, high-valuation inclusion of SpaceX upon its IPO.
The author's thesis is that these rule changes will create a "wealth transfer" by forcing passive index funds (tracking the NASDAQ-100 and S&P 500) to buy a small float of SpaceX shares at inflated prices, benefiting insiders who are selling.
Quality assessment: This is speculation. The author connects several dots (proposed rule changes, a hypothetical SpaceX IPO) to form a cohesive but unproven conspiracy-style thesis. It lacks primary sources for the rule changes and relies on a future event (the IPO) that has not been confirmed.

I previously made a post here, saying that SpaceX's IPO should be concerning to investors in passive funds tracking NASDAQ-100, because of the proposed rule changes to the NASDAQ-100 that is being forced by SpaceX.
I want to expand on that thesis: I think that S&P500 passive funds will also be forced to buy SpaceX shares after its listing on NASDAQ, causing a wealth transfer from passive retail investors to SpaceX insiders.
This is because S&P is making a rule change to allow immediate inclusion of companies with large market capitalisation.
(1) This means S&P will be removing the 12-month waiting period before a newly listed stock can be added to S&P500.
(2) This means SpaceX could immediately get included in S&P500 upon IPO and listing.
(3) This means passive funds tracking S&P500 will immediately be forced to purchase SpaceX shares (from existing SpaceX shareholders) based on SpaceX's market capitalisation.

I've come to the view that the NASDAQ-100 is really meant to serve as jet fuel (pardon the metaphor) to drive up the price of SpaceX shares.
(1) SpaceX will IPO on NASDAQ with a very small float, creating scarcity.
(2) SpaceX will be included in NASDAQ-100 after a very short time (15 days) because of the NASDAQ-100 rule changes.
(3) NASDAQ-100 passive funds will then be chasing a small number of SpaceX shares, driving the price up. Worse, because of the NASDAQ-100 rule changes, the small float will be artificially inflated 5x in terms of market capitalisation, which means the passive funds will be forced to buy 5x more shares.
(4) Because of the high price per share, SpaceX will likely be listed on S&P500.
The author claims S&P is changing its rules to allow immediate inclusion of large-cap IPOs, removing the 12-month waiting period. This change will force S&P 500 passive funds (like SPY) to buy a massive, newly-listed company (SpaceX) at a potentially inflated IPO price. This forced buying from a limited float will transfer wealth from passive investors to SpaceX insiders, negatively impacting the fund's value relative to the risk taken. The author implies that the S&P 500 index is being manipulated to serve as exit liquidity for large private companies, which is detrimental to the interests of passive retail investors holding the index. This suggests a bearish outlook on the index itself. The S&P rule change may not happen or may have different terms. SpaceX may not IPO or may not qualify for immediate inclusion. The impact of a single new company, even one as large as SpaceX, may be diluted across the entire index and not have a significant negative effect.
The author alleges NASDAQ-100 is changing its rules to allow inclusion after 15 days and to artificially inflate the market cap of low-float stocks by 5x for weighting purposes. Upon its IPO, SpaceX will have a small float. The rule changes will force NASDAQ-100 passive funds (like QQQ) to chase these scarce shares at a valuation five times higher than their actual float suggests, causing a massive price spike and benefiting insiders selling into this manufactured demand. The author believes the NASDAQ-100 is being used as "jet fuel" to artificially inflate SpaceX's share price, which is fundamentally negative for investors in the index who are forced to buy at these distorted prices. The NASDAQ-100 rule changes may not be implemented as described. The 5x float inflation rule might be misinterpreted or have safeguards. The market may price in these mechanics, or regulators could intervene.
