Michael Saylor, the founder of MicroStrategy, signed a stock sale agreement with the company last year, allowing him to sell up to 400,000 shares of stock by April of this year. With more than 90% of the plan completed, Saylor has made a net profit of about $370 million from this year's stock sales, thanks to the significant increase in the value of MicroStrategy (actually Bitcoin). Saylor is the largest shareholder of MicroStrategy, with Class B shares worth about $2.3 billion. As of the end of 2023, Saylor owns an additional 400,000 Class A shares of stock due to options he received in 2014, which he is quickly selling. According to documents, as of this week, Saylor has sold 370,000 shares of stock, worth a total of $372.7 million. As of the latest sales disclosed on Thursday, he now holds only 30,000 Class A shares.
