What is spot Bitcoin ETF flow?
When a spot ETF sees net inflows, its issuer must acquire Bitcoin to back new shares; net outflows work in reverse. Flow is the net of these creations and redemptions, expressed as a value per period — a direct read on demand through the ETF channel.
How it is calculated
The page follows aggregate net flow across tracked spot ETFs as a series. Because it nets creations against redemptions, it can be positive or negative on any given day.
How to read it
Sustained net inflows indicate persistent demand entering through regulated funds, which must be backed by real Bitcoin purchases. Sustained outflows indicate the reverse. Single days are noisy; the multi-day trend is the signal, and it is best read beside price and stablecoin supply.
What it does not tell you
ETF flow captures one demand channel, not all demand, and reporting can lag or be revised. It is context, not a complete picture. Live values are in the authenticated app.
