BlackRock’s IBIT Bitcoin ETF breaks 34-day streak with $430 million in outflows

The largest spot bitcoin ETF in the world has broken its longest streak of inflows yet, shedding $430 million as the price of BTC rebounded from its all-time high. BlackRock's IBIT fund, which has $69.2 billion worth of assets under management (AUM), saw $430 million in outflows on Friday, according to SoSoValue data. Overall, U.S. based spot Bitcoin ETFs shed $616 million on Friday, their worst trading day since February 26 of this year, following BTC's 4% drop in price over the past five days. Despite the recent outflows, IBIT continues to dominate the Bitcoin ETF field; its AUM is more than triple the runner-up, Fidelity's FBTC fund, which has an AUM of $20.8 billion. IBIT holds 3.33% of all BTC in circulation, compared to FBTC's 1%, according to SoSoValue.IBIT's share of the volume for the Bitcoin funds continues to hover around 80%, according to The Block's data. The funds overall broke a 10-day inflow streak on Thursday, with IBIT the only fund to report net inflows. "The IBIT vs Everyone Else flow disparity is interesting," Bloomberg ETF analyst Eric Balchunas wrote on X. "Normally IBIT takes in 70% of the net inflows but lately it’s over 100%. My theory: the latest rally was more an institutional buying spree than retail." "What a run over past 30+ days though," ETF Store President Nate Geraci said on X, referring to IBIT's broken streak. "IBIT now pushing $70bil in assets [less than] 17 months since launch...Not sure I have words to describe how ridiculous this is."Disclaimer: The Block is an independent media outlet that delivers news, research, and data.
