BlackRock's IBIT, the world's largest Bitcoin spot ETF, experienced a $430 million outflow on Friday, halting a 34-day streak of net inflows. This marked the largest single-day outflow since February 26, amid a 4% decline in Bitcoin's price over five days. Despite this, IBIT maintains a strong market position with $69.2 billion in assets under management, significantly outpacing Fidelity's FBTC, which holds $20.8 billion. IBIT continues to dominate trading volume among Bitcoin ETFs, accounting for approximately 80% of the market.
