Major asset manager Strive back on August 14, 2025 said MSTR was just one S&P 500 Index committee meeting away from entry, which has now already taken place. Many on Wall Street expect MicroStrategy (MSTR) to be announced as an addition to the S&P 500 on Friday, September 5, 2025 with a 96% likelihood Strategy will be in the September rebalance.

So, what does this mean for Bitcoin?

If MSTR joins the S&P 500, it would boost institutional demand for Bitcoin by giving passive funds indirect exposure and potentially increasing the stock's price beyond Bitcoin's performance, leading to higher Bitcoin prices as the funds buy MSTR shares and potentially more capital flows into crypto. The inclusion would also symbolize the growing mainstream acceptance of Bitcoin as a digital asset. Passive funds tracking the index would be forced to scoop up nearly 50 million shares, worth around $16 billion at current prices, according to an analysis by Stephens Inc. For Strategy's Saylor, whose relentless capital raising has funded a balance sheet holding roughly $70 billion in Bitcoin, the milestone would mean institutional validation of a strategy long dismissed by skeptics as reckless, while turning the likes of pension funds into indirect crypto holders in one fell swoop.
