According to PANews, Eric Balchunas, senior ETF analyst at Bloomberg, said on the X platform: "The 13F filing shows that a total of 414 companies finally held BlackRock's Bitcoin spot ETF 'IBIT' in the first quarter. This is incredible and breaks the record. Even for a new ETF to have 20 holders is extremely rare." Earlier, K33 Research said that 937 professional institutions had invested in US Bitcoin spot ETFs in the first quarter.
