BlackRock's Bitcoin ETF Attracts $604 Million Over Four Straight Days

BlackRock's iShares Bitcoin Trust (IBIT) has posted four consecutive days of net inflows totaling 9,269 BTC, valued at about $604 million at current prices. Launched in January 2024, the fund is increasingly viewed as a primary institutional gateway to Bitcoin. The run comes after what researchers characterize as a weak July for Bitcoin ETF flows across the sector, making the early-August pickup stand out. Flow breakdown Between August 3 and August 5, U.S. spot Bitcoin ETFs brought in roughly $626 million in net inflows. IBIT accounted for about $478 million over that three-day period, capturing the bulk of overall demand. On August 4, IBIT recorded $170.3 million of net inflows. On August 5, inflows rose to $196.8 million. Since launch, IBIT has typically represented 70% to 80% of daily inflows across the U.S. spot Bitcoin ETF market. Historically, its multi-day inflow streaks have generally fallen in a $200 million to $600 million range, placing the latest stretch at the top end. Cumulative net inflows into IBIT have now reached tens of billions since its January 2024 debut. Why July matters July saw notably softer Bitcoin ETF inflows, signaling a broader cooling in institutional demand. During a difficult stretch in late 2025, IBIT absorbed roughly $523 million in redemptions. What it suggests for Bitcoin Spot Bitcoin ETF flows have become a relatively clean, real-time gauge of institutional sentiment. Unlike on-chain indicators or futures positioning, ETF inflows reflect capital that has already cleared compliance processes, legal review, and allocation committees. Because ETF creation requires authorized participants to buy actual Bitcoin in the open market to back new shares, absorbing more than 9,000 BTC in four days represents meaningful demand relative to available spot liquidity.
