According to the latest regulatory filings filed on September 20, MicroStrategy holds a total of 252,220 bitcoins, accounting for 1.2% of the total supply of bitcoin. Grayscale GBTC and Mini BTC currently hold more than 254,000 bitcoins in total, and the gap between the two holdings is narrowing further. MicroStrategy has recently raised funds and is reportedly holding more than $1 billion in funds that have not yet been put to use (or at least have not yet been announced). It is speculated that if these funds are used to purchase more bitcoins, they will add thousands of bitcoins to its balance sheet and make its holdings far exceed Grayscale.
