MicroStrategy's market capitalization now meets the market cap rule for inclusion in the S&P 500.

However, the S&P also includes a profitability rule, which the MSTR does not meet -- because the government (via the FASB) pushed an anti-Bitcoin accounting rule that did not allow companies to value Bitcoin at the current price, only the price it was bought at.

That rule is repealed effective December 15, 2024, which could make MSTR massively profitable as of the following quarter, making it eligible for the S&P.

Once in the S&P, the vast majority of investors, who hold some version of the S&P will start to (indirectly) own Bitcoin. This would of course mean a massive capital inflow to MSTR, who would buy more Bitcoin, stimulating its feedback loop.
