Bitcoin ETFs just had their best three-week run of the year. A total of $3.8 billion poured into these products over the past three weeks, and the momentum isn’t slowing down much.
The most recent week — ending September 4 — brought in $986.9 million on its own. That’s up nearly 7% from the prior week’s $924 million, which itself followed a massive $1.92 billion opening week to this recovery stretch. Three weeks, three positive prints, each one building on the last. And yet, even with all that, Bitcoin ETFs are still sitting on a roughly billion-dollar net outflow since January 1. The math is close, but it’s not there yet.
Per data from SoSoValue, the deficit has shrunk fast — but it hasn’t disappeared.
BlackRock and Fidelity Running the Show
On September 4 alone, Bitcoin ETFs pulled $174.6 million. Not the biggest day — the session before had clocked $730.8 million — but it was enough for a second straight positive close. BlackRock’s IBIT grabbed $117.4 million of that, basically 67% of the entire day’s intake by itself. Fidelity’s FBTC added $57.2 million. Every other fund? Flat. Zero net movement across the board.
That’s pretty much been the pattern lately. When you zoom out to cumulative figures, IBIT has now pulled over $64 billion in total inflows since it launched. Fidelity’s FBTC sits at nearly $10.3 billion. Two funds. Two names. The rest of the field barely registers on days when sentiment gets choppy.
That kind of concentration matters. It means the daily ETF number is essentially a BlackRock-and-Fidelity story, and when either one has a slow session, the whole category feels it.
Bitcoin’s Price Dip Didn’t Stop the Buying
Here’s the part that’s interesting. Bitcoin’s price slid during this same stretch — from around $81,200 down to below $79,000 before steadying near $79,700. Prices fell. Inflows kept coming. That’s not nothing.
It probably means some buyers saw the dip as an entry point rather than a warning sign. Whether that’s right or wrong is unclear — a price drop doesn’t guarantee a bounce, and inflows alone don’t push Bitcoin back up. But the behavior is worth noting. Institutional money didn’t run when the price softened.
The effect on total assets under management was still painful, though. Between Thursday and Friday of that same week, the total valuation of assets held across Bitcoin ETFs dropped from $103.3 billion to $101.3 billion. That happened even as $174.6 million in fresh capital came in. Bitcoin’s price move just swamped the inflow math. That’s how volatile this asset class can be — new money arrives and valuations still fall because the underlying price is moving faster than the capital.
Ethereum and XRP ETFs Hit a Wall
While Bitcoin ETFs were pulling in nearly a billion dollars a week, Ethereum and XRP products hit a wall. Hard.
Ethereum ETFs brought in $218.4 million for the week. Sounds okay until you see the week before: $824.4 million. That’s a 74% drop in a single week. XRP ETFs went from $110.5 million to $19 million — an 83% collapse in weekly inflows. Both categories are still positive for the year, with Ethereum products at $863 million year-to-date and XRP-focused funds at $515 million. But the direction of travel shifted sharply.
So where did that capital go? Probably Bitcoin. The divergence is too clean to ignore. As Ethereum and XRP inflows cratered, Bitcoin ETFs were posting their best three-week run of 2026. Capital rotation is the obvious read, though it’s not confirmed.
The broader crypto ETF picture is messy. Bitcoin’s doing well. Everything else is kind of stalling. And the gap between IBIT’s $64 billion in cumulative inflows and the next-largest fund tells you everything about where institutional conviction is actually sitting right now.
For Bitcoin ETFs to call this a real recovery, the weekly inflows need to hold — and the roughly $1 billion year-to-date deficit needs to flip positive. The three-week streak got them close. Not there yet, but close.
IBIT’s September 4 single-day haul: $117.4 million.
