According to Farside Investors, Bitcoin ETF net flows on May 23, 2025, recorded a substantial net inflow of $211.7 million, driven primarily by BlackRock's IBIT with $430.8 million in inflows. However, significant outflows were observed from Fidelity's FBTC ($-73.7 million), ARK's ARKB ($-73.9 million), and Grayscale's GBTC ($-89.2 million). These shifts highlight strong institutional demand for IBIT while legacy products like GBTC continue to see redemptions. Crypto traders should closely monitor ETF flow trends as they directly impact Bitcoin price liquidity and short-term volatility. Source: Farside Investors (@FarsideUK, May 24, 2025).
