To be clear, Nasdaq-100 is NOT S&P100. These are very different indexes and not of equal standing. S&P100 is more restrictive and carries more importance to financial institutions.

Please read re-produced article below:-

 MSTR (MicroStrategy, now called “Strategy” in some reports) is not currently a member of the S&P 100.

Here’s the situation:

📌 S&P 100 vs. S&P 500

• The S&P 100 is a subset of the S&P 500, consisting of 100 large, established U.S. companies selected for size, liquidity, and industry representation. 

• To be in the S&P 100, a company must first be included in the S&P 500 (it’s essentially the top tier of the S&P 500). Because MSTR is not in the S&P 500, it cannot be in the S&P 100 either.

📌 Current Index Membership for MSTR

• MicroStrategy (MSTR) is currently included in the Nasdaq-100 index, which tracks the largest non-financial Nasdaq-listed companies by market cap. 

• However, it has not been added to the S&P 500 or S&P 100. Various recent reports indicate that despite meeting some technical requirements, the S&P index committee has kept MSTR out of the S&P 500, often due to discretionary decisions around its Bitcoin-heavy business model and related criteria. 

📌 Why MSTR Isn’t in the S&P 500 (and Thus Not S&P 100)

• Although MicroStrategy has a large market cap and sufficient liquidity, inclusion decisions also consider profitability, earnings consistency, and qualitative factors. Recent decisions show it missed selection in favor of other companies like SanDisk for the S&P 500. 

• Because the S&P 100 is drawn from the S&P 500, failing to get into the S&P 500 automatically means MSTR isn’t eligible for the S&P 100.
