Michael Saylor Responds to Robinhood’s Inclusion in S&P 500, Outlines MicroStrategy’s Performance

On September 5, 2025, MicroStrategy (MSTR) was excluded from the S&P 500 index, while online brokerage platform Robinhood (HOOD) joined. Publicly, Michael Saylor, CEO of MicroStrategy, reacted to this decision with a tweet and an infographic highlighting his company’s Bitcoin-focused strategy. The infographic showed MSTR outperforming both the S&P 500 and Bitcoin during the same period. Saylor’s tone suggested that while the stock was passed over for inclusion in the index, MicroStrategy’s performance underscored their success with a Bitcoin-centric approach.
