SpaceX, the aerospace company planning a major initial public offering (IPO), is expected to influence technology markets significantly. However, its inclusion in the S&P 500 index will not be immediate. The index enforces strict eligibility criteria, including consistent profitability, sufficient free float, and a minimum trading history. Since SpaceX does not currently meet all these requirements, its addition to the S&P 500 is likely to be delayed until at least 2027. This postponement also delays potential inflows from passive funds that track the index, which could amount to billions of dollars. The development highlights the rigorous standards companies must meet to join major market indices.
