It's now the world's fourth-largest holder of bitcoin, behind only creator Satoshi Nakamoto, BlackRock's iShares Bitcoin Trust and crypto exchange Binance, with a stockpile valued at close to $44 billion. MicroStrategy's market cap has swelled from about $1.1 billion when it was just a software company to $80 billion today.

While the rally was long underway prior to November, Trump's election victory last month added fuel. The stock is up 57% since then while bitcoin has gained about 44%. Trump once called bitcoin a "scam," but he was the industry's preferred choice in this election and was backed heavily by some of the leading players, including Coinbase.
