MicroStrategy Excluded from S&P 500: Impact on Bitcoin Markets & Institutional Perception

The S&P 500 recently made an exclusion decision that significantly impacts MicroStrategy (MSTR). The company, rebranded as Strategy, was excluded during the September 2025 index rebalance. This action, driven by concerns over asset volatility and sector balance, sees the inclusion of AppLovin, Robinhood, and Emcor Group. Despite financial criteria meeting, this exclusion reflects discretionary decisions regarding a firm’s association with Bitcoin and market volatility.
