Glassnode
US spot Bitcoin ETF flows, measured as the 7-day moving average of aggregated net inflows across the full US-listed slate, have failed to print a single positive day since mid-May, according to Glassnode's institutional flows chart. The data covers every major US spot BTC product, including BlackRock's IBIT, Fidelity's FBTC, the Grayscale GBTC and Mini Trust, Ark/21Shares' ARKB, Bitwise's BITB, Franklin Templeton's EZBC, and the newer Morgan Stanley MSBT, with values denominated in USD and sourced directly from ETF issuers.
Why it matters
The absence of a net positive day on the smoothed series for roughly five weeks is a meaningful shift in the post-launch trajectory of US spot BTC ETFs. The 2024 launch period was defined by a relentless institutional bid that drove several funds to tens of billions in cumulative assets; a flat-to-negative smoothed flow line suggests that bid has paused rather than reversed outright, since individual products such as ARKB and MSBT continue to register small positive prints on quiet sessions.
Market impact
The read is one of demand-side cooling rather than wholesale redemption. TradFi allocators appear to be sitting on the sidelines at current price levels rather than distributing, and the 7-day smoothing means a single strong session would not yet flip the series positive. Watch the IBIT, FBTC, and the newer MSBT prints alongside any re-emergence of GBTC outflows: a return to net positive smoothed flows is the cleanest signal that the institutional cohort has re-engaged.

Frequently asked questions
-
What does the Glassnode US spot BTC ETF flows chart measure?
It tracks the daily net flow of funds in the leading US spot Bitcoin ETFs, including IBIT, FBTC, GBTC, ARKB, BITB, and others, denominated in USD and sourced directly from the ETF issuers, with a 7-day moving average applied.
-
How long have US spot Bitcoin ETF flows been flat or negative?
According to Glassnode, the 7-day moving average of aggregated US spot BTC ETF flows has not recorded a single net positive day since mid-May 2026, a stretch of roughly five weeks.
-
Is the slowdown in ETF flows a sign of large redemptions?
Not necessarily. Individual products such as ARKB and MSBT still print small positive numbers on quiet sessions, suggesting the pattern reflects demand-side cooling and TradFi allocators staying on the sidelines rather than active distribution.
-
Which ETFs are included in the Glassnode aggregate?
The full US spot BTC slate: BlackRock's IBIT, Fidelity's FBTC, Grayscale's GBTC and Mini Trust, Ark/21Shares' ARKB, Bitwise's BITB, VanEck's HODL, Franklin Templeton's EZBC, Invesco/Galaxy's BTCO, WisdomTree's BTCW, and Morgan Stanley's MSBT.
-
What would signal a return of institutional demand for US spot BTC ETFs?
A flip of the 7-day moving average back to net positive is the cleanest leading indicator, ideally confirmed by sustained inflows into the largest funds (IBIT, FBTC) and the absence of fresh GBTC outflows.
