ETF Flow Tracker

US Spot BTC ETF daily net flows + AUM by fund

What is the ETF Flow Tracker?

Daily net flows into spot Bitcoin ETFs have been among the most important institutional-demand signals since 2024 — sustained inflows mean traditional capital is accumulating through regulated rails. No free public API exists for this data, so this page explains the metric and links the authoritative live trackers (SoSoValue, Farside).

How do I use the ETF Flow Tracker?

Watch streaks, not single days: a week-plus of consistent flows is the signal, alongside share shifts among leaders like IBIT. Divergence — price falling while inflows persist — has historically marked accumulation.

What should I watch out for?

Flow data publishes T+1, never intraday; and inflows can reflect basis trades (long ETF, short futures) rather than pure directional demand — check the futures basis when interpreting.
