According to Farside Investors, US spot Bitcoin ETFs recorded a total net outflow of 1,216.8 million dollars for the week, with IBIT at -1,085.7 million, FBTC at -115.8 million, ARKB at -85 million, GBTC at -172.4 million, HODL at -63.2 million, BITB at -7.9 million, and offsetting inflows at BTCO of 35.8 million and EZBC of 3.3 million, while BRRR and BTCW were flat, based on the weekly summary posted on farside.co.uk/btc, source: Farside Investors. IBIT accounted for roughly 89% of the week’s total net outflow, indicating concentrated redemptions in the largest fund by flows, calculated from the data on farside.co.uk/btc, source: Farside Investors. A weekly net outflow reflects redemptions exceeding creations across the ETF suite, and for cash-creation spot bitcoin ETFs this process entails underlying BTC transactions to meet redemptions as described in ETF mechanics, source: U.S. SEC Investor Bulletin on Exchange-Traded Funds and iShares Bitcoin Trust prospectus (SEC filing). Traders can monitor the daily flow updates and the largest vehicles (IBIT, FBTC, ARKB, GBTC) as primary drivers of aggregate weekly flows to gauge primary-market activity around US hours, source: Farside Investors, farside.co.uk/btc.

According to Milk Road, Bitcoin ETFs have experienced a 17,886% increase in week-on-week net flows, marking one of the top three all-time weekly inflows even before the week’s end (source: Milk Road Twitter, April 25, 2025). Notably, these inflows are distributed across multiple funds, not dominated by BlackRock alone, indicating broad institutional interest. This surge in ETF inflows is a bullish signal for Bitcoin price momentum and liquidity, offering traders actionable insights into market sentiment and the potential for increased volatility in the near term.
