S&P is considering modifying its rules to expedite the process of SpaceX entering the S&P 500 index.

According to informed sources, S&P Dow Jones Indices is considering modifying the rules for companies to join the S&P 500 index. This move could potentially allow SpaceX to join the index more quickly after its initial public offering. The rule change could mean that Elon Musk's space transportation and satellite company could experience a wave of passive buying amounting to tens of billions of dollars. Funds tracking the index must buy the newly added stocks, and approximately $24 trillion in assets are tied to the S&P 500 index. The sources mentioned that the index provider is in discussions with relevant parties to determine if rule modifications are necessary. No decision has been made yet, and S&P still needs to initiate a formal consultation process that will last for several weeks before any changes can be made.
