According to online reports, BlackRock's IBIT is the world's largest bitcoin spot ETF, with US$430 million in capital outflow on Friday, ending a previous 34 consecutive days of net inflows (three of which were zero inflows). During the same period, the overall net outflow of all bitcoin spot ETFs in the U.S. stock market reached US$616 million, the largest outflow in a single day since February 26, against the background of a decline in BTC prices of about 4% in five days. Despite the outflow, IBIT's market dominance remains solid, with assets under management reaching US$69.2 billion, about 3.3 times the second-place Fidelity's FBTC (US$20.8 billion). As of now, IBIT accounts for 3.33% of total Bitcoin circulation, far exceeding FBTC's 1%. Data shows that IBIT's share of all Bitcoin ETFs 'trading volume remains at around 80%. Eric Balchunas, an analyst at Bloomberg ETF, pointed out that IBIT recently accounted for "more than 100%" of all fund inflows, indicating that the recent market has been driven more by institutions rather than retail enthusiasm. Nate Geraci, president of the ETF Store, commented: "In less than 17 months, IBIT assets are approaching US$70 billion, which is unbelievable."
