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.

How the ETF Flow Tracker works

Explains how to read daily net flows of US spot Bitcoin ETFs as a signal of institutional demand. The page does not host flow data, because no free public API exists; it links to SoSoValue, Farside Investors and CoinGlass for live per-fund figures.

What you enter

  • None; the page is a guide with links to external live data providers.

What it shows

  • Links to SoSoValue (daily net flow and holdings by fund), Farside Investors (full daily flow history) and CoinGlass (holdings and net-flow charts)
  • Guidance for reading flow streaks, share shifts between funds and price-flow divergences

How to use it

  1. Open the SoSoValue link to see today's net flow by fund and total holdings.
  2. Open Farside Investors for the daily history table of every fund.
  3. Add up net flows over the last 5–10 trading days to judge whether a streak is forming.
  4. Compare the flow streak with the BTC price trend over the same days.
  5. Check whether a single fund dominates the total before drawing conclusions.

Formula

Daily net flow = sum across all funds of (creations − redemptions) in USD; multi-day streak = sum of daily net flows.

Worked example

A hypothetical week of total net flows in USD millions: +300, +150, −100, +200, +250. Weekly sum = 300 + 150 − 100 + 200 + 250 = +800 million USD, a week of net inflows despite one outflow day.

How to read the result

  • Multi-day streaks matter more than any single day's print.
  • Persistent inflows while price falls have historically been read as accumulation; outflows into rallies as distribution.
  • Watch share shifts among the largest funds, not only the total.

Limits and cautions

  • Flow data is published with a T+1 lag and cannot be confirmed intraday.
  • Some inflows may come from basis trades (long the ETF, short futures) rather than directional demand.
  • Figures differ slightly between providers because of timing and methodology.

Common questions

Where can I see Bitcoin ETF flows today?

Use the linked trackers: SoSoValue and Farside Investors publish daily net flows by fund, and CoinGlass charts holdings and net flows. Data usually appears after the US market close, with a one-day settlement lag.

Do ETF inflows mean the price will rise?

No. Inflows show demand through regulated funds, but part of it can be hedged basis trading and price depends on many other flows. Treat flows as one input, not a forecast.

Why doesn't this page show the flows directly?

There is no free public API for spot ETF flows, so the page links to the reference providers instead of copying or estimating their data.
