I am saying none of those things. S&P claims their S&P500 index is the "best single gauge of U.S. large-cap equities". That's taken directly from their website.

I dispute this claim, because the (current) rules for S&P500 inclusion exclude companies like SpaceX, Anthropic, and OpenAI. All of these companies are planning to IPO this year, and even if these companies maintain their present valuation for a year, none are eligible for S&P 500. Due to profitability requirements.

Yet these are all U.S. large-cap companies, among the top 20 largest in the U.S., and by S&P's description of the index, should be included. Not including these companies makes the index inaccurate.

Because SpaceX, Anthropic, and OpenAI are $1T+ companies. Google and Microsoft were much smaller relative to the size of the index when they joined.
