Robinhood Joins S&P 500, Outpacing MicroStrategy in Index Inclusion

Robinhood Markets Inc. secured a coveted spot in the S&P 500 index, replacing Caesars Entertainment Inc., while MicroStrategy's bid for inclusion fell short. The trading platform's shares surged 7% following the announcement, reflecting investor confidence in its retail-focused model.

The inclusion marks a milestone for the commission-free brokerage, which has democratized market access through its mobile app. Analysts view the selection as validation of Robinhood's financial stability and growing institutional appeal. The formal addition to the index will occur on September 22.

With a market capitalization exceeding $89 billion, Robinhood now stands poised to potentially outperform established S&P constituents. Some analysts speculate it could rival Palantir Technologies Inc. as the index's top performer, particularly given its 65% year-over-year transaction revenue growth in Q2 2025.
