As far as I know, will still be included in the NASDAQ 100 (since NASDAQ changed their rules already and SpaceX will be listed on that exchange).

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. The longer this company is not in the index, the longer this error compounds. In the coming few months, multiple giga-cap companies (SpaceX, OpenAI, Anthropic) are all planning to IPO. These companies will likely never meet S&P profitability inclusion criteria for the nex…
> Because the index needs accuracy. No, it doesn't. At least, not the way you are probably defining it. This sounds to me like you may be trying to use the index for something it's not really meant to be used for.
What is the S&P 500 meant for then? It was created in 1957 as a benchmark of US equity performance. That's S&P Global's own stated purpose. If it's systematically excluding companies that represent significant chunks of total US market cap, the index isn't doing its job.

And where did the ad hominem part arise?
It's all empty words. > a very thorough and nuanced discussion > bunch of smart investment / finance guys > No click-bait-sky-is-falling content. The middle one is the ad-hominem puffery. The rest isn't quite exactly 100% 'of the person's, but still doesn't give me any actual leads into what the content is: its just empty puffery.

Re: SpaceX, Other Mega IPOs Denied Fast Index Entry by S&P
#174Good. Indexes are supposed to be slow-moving, precisely due to their entry requirement of sustained profitability that skews towards mature companies. All that an inclusion of these new companies would accomplish is a bailout of their stockholders by pension funds and ETFs where millions of regular people shoulder all the downside risk. SpaceX and OAI stock will be available through Robinhood, Questrade and all the o…
It’s important to note that index funds will eventually get in, so it’s not like 401k will never be holding these stocks. It would be silly to assume that the stock is going to tank that much on day 1, on the asumption that there are not enough investors to buy the big three IPOs that are coming out this year. There is plenty of money in the market, and everyone knows index funds will buy these stocks when the companies get in, so everyone will be able to dump them if needed in a year or so.
Btw I don’t really know how index funds work, but if they need to track the index as closely as possible, they will all have to buy those stocks on a certain day, no? There will be a crazy price hike when they do so. Or maybe they have terms that let them smoothen their trading around entry and exit?

#175Looks like US society and its systems are well and alive despite the usual doom and gloom.
It’s a single index… that doesn’t say anything about the country and its systems

#176Thank goodness. I was v concerned about the implications of this.

"Because the index needs accuracy.", and I would argue that include price accuracy not just inclusion accuracy. The S&P is a benchmark that is designed to reflect a subset of the market, and giving only some companies early access to the benchmark changes the benchmark. So if you want a benchmark that's designed to include all the big stocks regardless of age, profitability, etc then go make a new benchmark. The only…
"go make a new benchmark" completely ignores how this works in practice. Benchmarks are only useful because everyone uses the same one, you can't swap it out. The S&P 500 benchmark is used as a comparison for trillions of dollars of mutual funds, index funds, and institutional mandates. The further the S&P 500 strays from reflecting the actual market, the more useless it becomes.
Also the S&P criteria have been revised multiple times, it's not some sacred unchangeable document.

#178Note that Nasdaq and Russel did put in place fast entry rules. S&P is the only one that didn’t. https://www.nasdaq.com/articles/new-fast-tracks-account-olde...
CRSP is changing the index VTI tracks
I wasn't familiar with the Center for Research in Security Prices (CRSP). Apparently they were acquired by Morningstar in February 2026. I also found this press release from Vanguard announcing they will be updating fund names (including VTI) to reflect the acquisition
https://corporate.vanguard.com/content/corporatesite/us/en/c... but nothing on the fund composition or rule changes.

>All that an inclusion of these new companies would accomplish is a bailout of their stockholders by pension funds and ETFs where millions of regular people shoulder all the downside risk. Carvana is the poster child for this. It's astonishing that a company with a history of shady practices, and that has yet to offer a convincing explanation for why it is not a scam, is part of the S&P 500.
Ah, so you'd like the passive broad market index which contains the 500 biggest good companies?
Do tell us if you find one I guess.

> If a significant percentage of the market is excluded from the index because they don't meet index inclusion criteria, then then index stops being a useful benchmark. So what's the reason for fast entry specifically? If it's a significant portion of the market and will remain so, it doesn't need an accelerated entry. A benchmark should be conservative about new entrants so that it doesn't turn from a market benchma…

There are indexes which explicitly try to capture the entire market- the Russell 3000 is most prominent, but the Wiltshire 5000 is another one, and Vanguard's Total Market Funds and ETF follow the CRSP US Total Market Index. I believe all of them plan to include SpaceX/OpenAI etc. within a few weeks of its listing, which is what I'd expect from their goal of tracking the total market. Other indexes follow just a few stocks- most famously, the Dow Jones Industrial Average (built during an era of when it had to be calculated by hand every night) looks at just 30 stocks in a weird way(1).
The S&P 500 isn't either of those. It has a list of criteria for inclusion, one of which is profitability. They are sticking with that criteria. If you don't like it, sell your VOO and buy VTI instead.
1: It is essentially impossible to build an index that tracks the DJIA because, since it was done on pencil and paper, it isn't actually market-cap weighted, but is share price weighted, with a correction factor for each stock to account for splits, one stock replacing another, etc. Because of that nature, the weights of the DJIA change minute by minute, so someone attempting to track it would be subject to enormous error.
