The purpose of the S&P 500 is to be the "best single gauge of U.S. large-cap equities". That's direct from their website. I never dispute this.
I dispute the fact they claim to be the best benchmark of large-cap U.S. equities, yet have rules that (currently) exclude large-cap equities like SpaceX, OpenAI, or Anthropic.
Sure, but then it comes down to your opinion vs the S&P board's opinion. I suspect (given that there's only been a few days of this getting into the public eye) that more people support the S&P's position vs their critics. But the trade flows will show if people get out of SPX (or SPY/VOO) in the coming days.
My issue is that so many people have forgotten the purpose of the S&P 500 index (i.e. it's a benchmark to reflect the large-cap U.S. equity market), and instead treat it as a list of approved companies they should blindly invest their 401ks into. These people do not want to invest their retirement funds into the upcoming IPOs of the overpriced & unprofitable (SpaceX, Anthropic, OpenAI), and then are arguing the benchmark index should not include these companies.
But at a fundamental level, the S&P500 index exists to track the market. It was created decades before passive investing even existed. These companies are all large enough to qualify as major members of the index. If S&P started arbitrarily excluding parts of the market they find uninvestable, then that's compromising the integrity of the index, and defeats the purpose of the index entirely.
Reading this thread, there is so much confusion happening.
No? Where did I say that?

Right here:
> Because the index needs accuracy. If a company is 1-2% of the total US market cap and not included in the index, then the index is wrong right now.
If it's not a total US market index, then why is the index wrong to not include it?
Edit: and then again here:
