According to Farside Investors, Bitcoin ETF net inflows totaled $425.5 million on May 5, 2025, with BlackRock's IBIT ETF leading at $531.2 million in positive flow. Meanwhile, notable outflows were seen in Fidelity's FBTC (-$57.8 million), Bitwise's BITB (-$22.7 million), and Grayscale's GBTC (-$16.4 million). Persistent net inflows indicate continued institutional demand for Bitcoin exposure, favoring IBIT as the primary trading vehicle. Traders should monitor these ETF flow patterns as they often correlate with short-term Bitcoin price momentum and liquidity shifts (source: Farside Investors via Twitter, May 6, 2025).
