Bloom Energy was just named to the S&P 500. These other stocks are joining the index as well.

Bloom Energy has been named to the S&P 500, while Molson Coors Beverage, Builders FirstSource and Trade Desk will be removed from the benchmark index. The change reflects the index committee’s ongoing effort to keep the S&P 500 representative of the large-cap U.S. equity market.

Such index adjustments carry practical significance because many active and passive funds track the S&P 500. When constituents are added or removed, these funds often buy or sell shares to mirror the updated composition. For Bloom Energy, inclusion could broaden its investor base and increase trading liquidity—while for the removed companies, the exit may spark temporary selling pressure from index-tracking portfolios.

Index membership is not a verdict on fundamental quality. It is determined by objective criteria such as market capitalization, liquidity and profitability. For investors, understanding how and why these changes occur offers context for market movements. Each addition or removal tells a distinct story about a company’s current standing and the evolving shape of the broader economy.
