The S&P 500 has maintained strict listing requirements that could keep major IPOs like SpaceX out for years, while Nasdaq has relaxed its rules to allow entry into the Nasdaq 100 within just 15 trading days. This divergence in index operator policies creates different pathways and timelines for mega-cap companies seeking inclusion in major equity indices.
