Frequently asked questions
What are Bitcoin ETF flows?
They are the net money entering or leaving the US spot Bitcoin ETFs each day through share creations and redemptions. A net inflow forces the fund to buy spot Bitcoin; a net outflow forces it to sell. That makes them the most direct gauge of institutional BTC demand.
What were the latest Bitcoin ETF flows?
On August 21, 2026, the 12 US spot ETFs recorded an aggregate net flow of +$20.0M. Month to date they total +$2.00B, and year to date −$3.93B.
How often is this data updated?
Daily. An automated process collects the flows published by Farside Investors after the US market close and refreshes this page. The most recent day may be revised as the last issuers report.
Why do ETF flows matter for the Bitcoin price?
Because they translate into real purchases or sales in the spot market: the ETFs custody over 1.2 million BTC and their daily flows move hundreds of millions of dollars. Sustained streaks of inflows or outflows have historically coincided with rallies or corrections.
