On July 15, two Bitcoin ETFs in the United States have surpassed MicroStrategy more than six months since their launch. At the same time, another ETF is chasing MicroStrategy, which was once the king of bitcoin holdings in the corporate world. According to current prices, BlackRock's IBIT currently holds 316,284 bitcoins, worth about $19.80 billion. The largest corporate holders of bitcoin as of July 12 include: IBIT, GBTC, MSTR (MicroStrategy), FBTC, ARKB, BITB, MARA, HODL, TSLA, COIN, HUT, BRRR, SQ, CLSK. GBTC (grey release) is also not the only growth bitcoin ETF; although it is not popular with retail investors due to its high management fees, it has gradually gained the attention of institutional investors in recent months and currently holds 273,726 bitcoins. For now, MicroStrategy remains firmly in third place, holding 226,331 bitcoins. However, Fidelity's FBTC is quickly catching up, holding 176,992 bitcoins. Tether holds 75,354 bitcoins, while ARK21Share's ARKB holds 47,764 bitcoins. MattHougan, chief investment officer at Bitwise, believes that while bitcoin spot ETFs have attracted about $15 billion in net new assets since their listing, they are only "just getting started." If his prediction comes true, MicroStrategy could soon be overtaken by FBTC and other bitcoin ETFs in the top three.
