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 issuer publishes its fund's holdings every business day, and a fund's flow is the day's change in those holdings, in dollars. A single fund's flow is mostly about that fund's distribution; the total across funds is about the asset.

The table shows each fund's latest reported day: the flow and the coins it holds. The funds are IBIT and ETHA from iShares, BITB and ETHW from Bitwise, and ARKB from ARK 21Shares, and the totals cover these five, not every spot ETF.

How to read it

  • Read the total over a week, not a day. 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.
