Strategic Implications

The inclusion of SpaceX in index funds may indicate a shift in how large, unprofitable companies are treated by index providers, which could have implications for the broader market and investor portfolios. The rules change suggests that index providers are adapting to the growing number of large, privately-held companies going public, which may lead to increased exposure to these companies in retirement accounts.

What Happened

New Index Rules Bring Trillion Dollar Companies to Retirement Accounts

SpaceX has become the first company to benefit from new index rules, entering the CRSP US Total Market Index just five days after its IPO. The change in rules, which now allow companies with lower public floats to be included, may also pave the way for OpenAI and Anthropic to join index funds in the future. The S&P 500 index, however, has decided not to change its rules, excluding SpaceX from its index for now. This development was reported by Moneywise.
