The top 3 most popular index fund ETFs track S&P500, which doesn't really pull this kind of shenanigan. Only QQQ tracks the NASDAQ 100 and it's in 5th place by assets under management.
You should probably read a book about index investing if you are going to invest.
Yeah, but the S&P500 is hugely concentrated in MAG7, which are all Nasdaq listed. So when they all get sold to buy SpaceX, you can bet your butt something's gonna happen to a S&P500 ETF.
SPY is somewhat concentrated in mag7 (or the other 93 stocks in QQQ), but only a small percent of mag 7 are owned via QQQ, which has 400B aum. (Mag 7 is 19T.)
The bottom line is all this fuckery is a tiny blip for most investors. It's far more concerning to me the societal harm that will come from further enriching Elon.
