What three companies own 88% of the S&P 500?

Written by Editorial Team | Last Updated: August 2026

While no three companies own the S&P 500 index—which is instead comprised of 500 individual publicly traded corporations—common market mythology or index concentration queries often point toward mega-cap asset management giants that control massive institutional equity stakes, such as BlackRock, Vanguard, and State Street Global Advisors. These three massive index fund managers hold trillions of dollars in assets tracking major benchmarks like the S&P 500 on behalf of retail and institutional investors worldwide.
