US Bitcoin ETFs Record $3.8B Three-Week Surge, Marking 2026's Strongest Period
Weekly Bitcoin ETF inflows climbed approximately 7% compared to the prior week, pushing the three-week total to a 2026 peak of $3.8 billion, even as Ether and XRP ETF inflows experienced significant declines.
Exchange-traded funds tracking spot Bitcoin prices in the United States have posted their most robust three-week period of capital inflows in 2026 while Bitcoin has been trading in the vicinity of $80,000.
These investment vehicles pulled in $986.9 million during the week that concluded on Friday, pushing the combined net inflows for the previous three weeks to $3.8 billion, based on data from SoSoValue.
The aggregate net assets held by these funds reached $101.3 billion on Friday following a brief climb to $103.3 billion the previous day, with cumulative net inflows hitting $55.6 billion.
The surge in ETF demand represents a dramatic reversal from substantial outflows seen earlier in 2026, although the year-to-date net flows still sit at approximately $1 billion in the negative.
Friday's Bitcoin ETF inflows moderate following Thursday's spike
Spot Bitcoin ETFs in the United States pulled in $174.6 million in net inflows on Friday, representing a significant decrease from the nearly $731 million that flowed in the day before.
The iShares Bitcoin Trust (IBIT) from BlackRock, which holds the position as the largest spot Bitcoin ETF measured by assets, captured $117.4 million on Friday, representing approximately 67% of the day's aggregate net inflows, based on data from Farside Investors.
The Wise Origin Bitcoin Fund (FBTC) from Fidelity stood as the sole other fund to post net inflows, pulling in $57.2 million, while the remaining US spot Bitcoin ETFs registered zero net flows for the day.
The deceleration occurred as Bitcoin dropped from approximately $81,200 to momentarily trade below $79,000 on Friday. At the time of publication, Bitcoin was trading at $79,716, representing an increase of roughly 2.6% across the past seven days, based on CoinGecko data.
Bitcoin ETF momentum builds while Ether and XRP flows weaken
When compared to the week before, Bitcoin ETF inflows rose by roughly 7%, whereas inflows to US spot Ether and XRP ETFs dropped by approximately 74% and 83%, respectively.
Inflows to spot Ether ETFs fell to $218.4 million from $824.4 million, while XRP ETF inflows slid to $19 million from $110.5 million, based on SoSoValue data.
In spite of the reduced inflows, both Ether and XRP ETFs continue to show positive performance for the year. Spot Ether ETFs in the US have accumulated approximately $863 million in net inflows since the start of the year, while XRP ETFs have drawn in roughly $515 million.
