Bitcoin ETF Flow Analysis — April 2026 Edition

Bitcoin spot ETF flows in April have been the most institutionally constructive of the year — even with BTC trading sideways.

Cumulative April net inflows sit at $4.8B as of last week, the strongest month since the original launch window in early 2024. IBIT alone accounts for $2.9B of that figure, with FBTC contributing another $1.1B.

Deeper signal is the steadiness. April has produced 14 consecutive trading days of net positive inflows across the aggregated complex, vs the choppy single-day swings of late 2025. That kind of sustained flow comes from systematic and model-driven allocators, not retail.
