MicroStrategy is set to increase its Bitcoin portfolio through a $500 million offering of convertible senior notes, intended for institutional buyers, with an additional option for $75 million. These unsecured senior obligations, maturing in 2032, may be converted into cash, MicroStrategy stock, or a mix of both. This move marks the company's third major convertible notes initiative in 2024, aiming to expand its already substantial Bitcoin holdings of 214,440 coins valued at approximately $14.4 billion.
