Mega-IPO candidates including SpaceX are expected to face a long road to entry to the S&P 500 Index, after the company that makes the rules rejected a proposal that included relaxing the requirement that they be profitable.

S&P Dow Jones Indices¡¯ index committee declined to remove a rule that companies generate positive net income for the past year, including the most recent quarter, the firm announced Thursday after a month-long consultation.?

Evercore ISI research analysts don¡¯t expect Elon Musk¡¯s rocket, satellite and artificial intelligence company to generate positive net income on an annual basis until 2027, according to a person familiar with the forecasts, who asked not to be identified as the information isn¡¯t public. That could mean its entry is held up until sometime in 2028 if the rule remains in place.
