Per-fund flows (2026-09-18)

A fund's flow for a day is the change in the coins it holds, from the issuer's own daily holdings file, valued at that day's price. Funds whose issuer publishes no machine-readable file (most of them) show no new flows since 11 September 2026; the daily total is shown only for days with full coverage.

What this data is

Spot ETF flows

A spot ETF holds the coin. When investors buy more shares than they sell, the issuer creates new shares and buys coin to back them; when they sell, the issuer redeems shares and sells coin. Those creations and redemptions are the flows, and they are the most direct measure of how much traditional money is entering or leaving bitcoin and ether on a given day.

Each fund reports its own figure after the US close. The daily total across funds is the number markets quote. A single fund's flow is mostly about that fund's distribution; the total is about the asset.

The table shows every fund's flow for each trading day and the daily total. Holdings and assets under management are shown where the issuer publishes them.

Data checks. Every dataset is checked against its source once a day. The last run, 18 Sep 05:40 UTC, raised a warning on this dataset. The rows in question are under review.

How to read it

  • Use the total, and use it over a week. One day's flow is noise; five days of the same sign is a trend.
  • Redemptions from the highest-fee fund while the rest see inflows is fee migration, not selling.
  • Flows lag price by a day: today's print reflects orders placed on yesterday's move.

Analysis of what the data shows, not advice. XOOMAR does not recommend buying, selling or holding anything.

Frequently Asked Questions

Where do the flow numbers come from?
From the issuers' own daily holdings files: a fund's flow for a day is the change in the coins it holds, valued at that day's price. Funds whose issuer publishes no holdings file show no new flows since 11 September 2026; figures before that date were compiled from issuer reports by a third party and are kept as history.
Which funds have current flows?
The ones whose issuers publish a daily holdings file we can read: IBIT and ETHA (iShares), BITB and ETHW (Bitwise), ARKB (ARK 21Shares). Others are added as their issuers publish files. Through 11 September 2026 the table also carried figures compiled from issuer reports by a third party; those rows are kept as history.
How far back does the history go?
To the first trading day: 11 January 2024 for the bitcoin funds and 23 July 2024 for the ether funds.
When does data update?
Three times a day: after the US close, at 12:30 UTC and at 16:30 UTC, as issuers post the previous day's holdings file (iShares posts in the US morning).
