BTC ETF Flows Hit $1.4B in a Single Week
April spot Bitcoin ETF inflows are the highest since launch — IBIT and FBTC pull 78% of the volume.
Spot Bitcoin ETF inflows hit $1.4B in the third week of April, the highest single-week reading since the Q1 2024 launch. BlackRock IBIT pulled $740M; Fidelity FBTC pulled $360M; the remaining $300M was split across the long tail.
The two-issuer concentration is the structural story. IBIT and FBTC together control 78% of net flows YTD. That is a more extreme concentration than the gold ETF market reached at any point in its first 24 months.
On-chain matching: the ETF buying is real BTC accumulation. Coinbase Custody wallet movements show the buys land at the same week as the issuer creation flows. There is no synthetic exposure layer hiding the real demand.
