According to Farside Investors, US-listed Bitcoin ETFs recorded a total net inflow of $607.1 million on May 21, 2025, marking a significant surge in institutional demand. The iShares Bitcoin Trust (IBIT) led with $530.6 million, followed by Fidelity's FBTC at $23.5 million and Bitwise's BITB at $20.5 million. Other funds such as ARKB and HODL saw modest inflows, while several products like BTCO, EZBC, BRRR, BTCW, and GBTC reported zero flows. This robust ETF inflow is a bullish signal for crypto traders, indicating heightened market confidence and likely supporting upward price momentum in the near term (source: Farside Investors, Twitter, May 22, 2025).

According to Farside Investors, Bitcoin ETF net inflow reached $674.9 million on May 2, 2025, with BlackRock's IBIT ETF accounting for the entire inflow and all other major ETFs, including FBTC, BITB, ARKB, and GBTC, recording zero net flows. This concentrated inflow into IBIT indicates strong institutional buying demand for this specific fund, suggesting a potential bullish sentiment for Bitcoin price action in the short term (source: Farside Investors on Twitter). Traders may interpret this as a sign of market confidence focused on the IBIT product, which could influence Bitcoin spot and futures trading strategies.
