Glassnode
US spot Bitcoin ETFs logged a net outflow of $101.48 million in the most recent reporting window, according to Glassnode's US Spot ETF Net Flows tracker, with the 7-day moving average still pinned in negative territory.
The print extends a run of net outflows on nearly every trading session since May 7, a pattern the source channel flagged as a persistent institutional sell signal now stretching past two weeks. The cohort covered by the metric spans the eleven US-listed spot Bitcoin ETFs — BlackRock's IBIT, Grayscale's GBTC and BTC Mini Trust, Fidelity's FBTC, Ark/21Shares' ARKB, Bitwise's BITB, VanEck's HODL, Valkyrie's BRRR, Invesco/Galaxy's BTCO, Franklin Templeton's EZBC, and WisdomTree's BTCW — with daily balances pulled directly from issuer disclosures and converted to USD at the 16:00 New York fixing.
Why it matters
A single-day net outflow inside a $100M range is routine noise for a product complex that has moved tens of billions cumulatively since launch. The streak is the story. Two straight weeks of net selling on a cohort this large points to a structural supply drip rather than a one-off rebalance, and it shows up directly in the 7-day moving average staying below zero — a clean enough read for any allocator watching the flow tape.
Market impact
The mechanical read is straightforward: ETF-authorised Bitcoin is hitting the market on a near-daily basis without an offsetting bid from the same wrapper. The $101M print is small relative to total AUM, but the persistence of the flow is what the source channel is calling out — supply keeps expanding into a tape that has not yet found a clear demand counterweight. Watch the 7-day SMA for a turn back above zero; that is the cleanest signal that the institutional bid has re-engaged.
