Just noticed Michael Saylor's net worth jumped nearly 16% so far this year to around $7.37 billion. Pretty wild considering his company MicroStrategy stock is up about 12% since January. The guy just made it onto the Bloomberg Billionaire 500 list too. What caught my attention is how concentrated his wealth actually is - roughly $6.72 billion is tied up in MSTR equity while only about $650 million sits in cash. That's a lot of eggs in one basket.

The real story here is MicroStrategy's Bitcoin play. They're holding almost 660,000 BTC now, which is like 3.3% of all Bitcoin in circulation. At current prices that treasury is worth around $72-73 billion. So basically Michael Saylor's net worth is really just following two things: how the stock performs and how the Bitcoin market moves. The company's been accumulating aggressively but claims they're doing it carefully to avoid moving prices.

Interesting thing is MSTR actually missed getting into the S&P 500 back in August even though it hit a lot of technical requirements. The committee apparently looked at broader factors beyond just the numbers. Anyway, the stock's been choppy lately - up 2.5% on Friday but down about 12% over the last month. So if you're watching Michael Saylor's net worth, you're basically watching two things: corporate software earnings and Bitcoin holdings. That's the whole game right there.
