One of the most important stories in the market right now is not just that SpaceX, OpenAI and Anthropic may go public.
The bigger story is what happens after they go public.
According to the Financial Times, potential blockbuster IPOs from SpaceX, OpenAI and Anthropic could trigger a massive wave of trading because of new โfast entryโ rules that may allow some newly listed companies to enter major indices much faster than before. Passive investors could be forced to sell billions of dollars of existing holdings to make room for these new stocks.
This matters because these companies are not normal IPO candidates.
We are talking about some of the most valuable private companies in the world. If they go public at extremely large valuations, they could immediately become some of the largest companies in public markets.
And that creates a very unusual situation.
A company could go public at a massive valuation, with a limited amount of shares available to trade, and then be added quickly to major indices.
That means index funds and ETFs may have to buy.
Not because the stock is cheap. Not because the company is easy to value. Not because the risk/reward is clearly attractive. But because the index rules require it.
That is the hidden risk.

Most people think passive investing is simple.
You buy the index, pay low fees, diversify globally, and avoid emotional mistakes. That is mostly true.
But index funds follow rules. And rules create flows.
If a company enters a major index, funds that track that index usually need to buy it. At the same time, they may need to sell other stocks to fund that purchase or to rebalance the portfolio.
When the company is small, this is not a big deal.
But when the company is potentially worth hundreds of billions or even trillions of dollars, the impact can be enormous.
Nasdaq has already changed its methodology to create a โfast entryโ path. Under the new rule, certain newly listed companies can become eligible for inclusion in the Nasdaq-100 after only 15 trading days if they meet specific size and eligibility requirements.
S&P Dow Jones Indices has also consulted on reducing the IPO seasoning period from 12 months to 6 months for certain indices, including the S&P 500.
FTSE Russell has also proposed a fast-entry mechanism for IPOs in Russell U.S. equity indices, specifically mentioning the possibility of large 2026 IPOs such as SpaceX, OpenAI and Anthropic.
So this is not a theoretical debate anymore.
Index providers are preparing for a world where the largest private companies may become public very quickly, and where traditional index inclusion rules may be too slow to reflect the new market reality.

A normal IPO is usually absorbed by the market gradually.
Investors analyze the prospectus. The company reports earnings. Analysts build models. The market starts to understand the business.
Price discovery takes time. But mega IPOs are different.
If a company like SpaceX, OpenAI or Anthropic goes public at a huge valuation, the market may not have much time to understand the business before index-related buying begins.
That is especially important if the free float is small.
Free float means the percentage of shares actually available for public trading.
If only a small percentage of the company is available, but a huge amount of passive money needs exposure, the market can become distorted.
Too much demand. Too little supply.
Everyone knows index funds need to buy.
That creates an opportunity for hedge funds and traders to buy ahead of passive flows.
This is called front-running. It is not necessarily illegal. It is often just the market understanding predictable flows.
But it can push prices higher before index funds buy.
In simple terms: passive investors may arrive late to a party where everyone already knew they were coming.

This is the most uncomfortable part. Private companies are staying private for much longer than they used to.
By the time they go public, a lot of the early wealth creation may have already happened in private markets.
Venture capital firms, private equity funds, early employees and founders may have owned these companies for years.
When the IPO finally happens, public investors get access.
But private investors get liquidity.
That does not automatically mean the public investor is making a bad investment. Sometimes great companies keep compounding for decades after going public.
But the incentive structure matters.

Not investment advice. The author may have financial interests in the mentioned instruments.
If a company goes public at an extreme valuation after years of private-market hype, public investors need to ask:
- Am I buying the next great compounder?
- Or am I providing liquidity to people who already made the easy money?
That question becomes even more important if passive funds are forced to... Show More
Very interesting point, Francisco. I think many investors still underestimate how much passive flows can distort price discovery in mega IPOs.
If companies like SpaceX or OpenAI go public with limited float and instant index inclusion, the demand pressure from ETFs alone could become massive regardless... Show More
