MicroStrategy (MSTR) will officially join the Nasdaq 100 Index on December 23, 2024, becoming the first Bitcoin company to be included in the index. Analysts expect this to bring about $2.1 billion in passive ETF buying and increase market liquidity. Although the company has not yet met the S&P 500's profitability standards, MicroStrategy is expected to be included in the S&P 500's quarterly adjustment in June 2025 after the new accounting standards take effect in January 2025. The company currently holds 439,000 bitcoins, worth more than $45 billion.
