According to Golden Finance, MicroStrategy founder Michael Saylor signed a stock sale agreement with the company last year, allowing him to sell up to 400,000 shares in the period ending in April this year. With the plan more than 90% completed, Saylor has netted about $370 million from this year's stock sales, thanks to the sharp rise in the value of MicroStrategy (actually Bitcoin). Saylor is MicroStrategy's largest shareholder, with Class B holdings worth about $2.3 billion. By the end of 2023, Saylor owns another 400,000 Class A shares due to options obtained in 2014, and these are the shares he is selling quickly. Documents show that as of this week, Saylor has sold 370,000 shares of stock for a total value of $372.7 million. As of the latest sale disclosed on Thursday, his holdings of Class A shares have fallen to 30,000 shares.
