Spot Bitcoin ETF Inflows Turn Positive Across All Time Windows for First Time in Months

U.S. spot Bitcoin (BTC) ETF flows have flipped to positive across every rolling period monitored by analysts, marking the first broad-based alignment in months. The move points to renewed institutional demand as BTC trades around $77,700, while cumulative lifetime net inflows stand at $62.8 billion. Bloomberg ETF analyst Eric Balchunas said the rebound has been driven in large part by BlackRock's iShares Bitcoin Trust (IBIT), which has attracted $3 billion in recent inflows—placing it in the top 1% of all ETFs by flow volume. "Bitcoin ETFs flows are back in the high life.. every single rolling period we track is now positive, haven't seen that in months," Balchunas said. Data from SoSoValue shows the 12 spot Bitcoin ETFs took in $335.8 million in net inflows on April 22 alone. IBIT led with $246.9 million, followed by Fidelity's FBTC with $56.7 million and Bitwise's BITB with $15.4 million. Momentum was stronger in the week ended April 17, when spot Bitcoin and Ethereum ETFs together drew $1.37 billion in net inflows—the largest weekly total since January 2026. Despite the upswing, lifetime cumulative inflows have yet to set a new high. Balchunas said totals likely need a couple billion more to surpass $62.8 billion. With traditional finance firms expanding crypto exposure, the pace of inflows through the rest of April could determine whether a new lifetime record is reached before May.
