So you are saying that S&P 500 should be merged with Russell 2000 or rather just become a fully market index to be more "accurate". You do know that's something that exists already, having different indexes makes perfect sense and consumers can pick the ones they want based on their risk profile and preferences.

It took Google 2 years to get into S&P 500. For Microslop it was 8 years (!). So what's new?
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.
> [Google and Microsoft took years go get into the index], so what's new?
Because SpaceX, Anthropic, and OpenAI are $1T+ companies. Google and Microsoft were much smaller relative to the size of the index when they joined.
