American spot bitcoin ETFs absorbed $2.4 billion over the past week, successfully driving their 2026 net flows into positive territory, while ether vehicles bounced back from the previous week’s $140 million exit by gathering $690 million in net subscriptions.
United States spot bitcoin ETFs attracted more capital last week than during any single week since October 2025, which proved sufficient to push their annual 2026 net tracking into the green just two months after suffering a deficit close to $6 billion. Ethereum funds similarly changed direction, posting substantial net deposits following a prior week defined by redemptions.
Market participants injected $2.4 billion into these bitcoin instruments during the seven-day period ending September 25, according to metric evaluations compiled by The Block utilizing SoSoValue data. The most recent preceding week with higher collections concluded on October 10, 2025, when the assets accumulated $2.7 billion as bitcoin climbed toward a then-unprecedented valuation of $126,296.
The previous week’s inflows placed bitcoin ETFs roughly $934.1 million ahead for the calendar year, with year-to-date figures crossing into positive metrics on Tuesday. These same vehicles experienced an annual drawdown around $5.8 billion as recently as July 13, spanning slightly more than two months ago.
Spot ether investment products brought in $689.9 million across that exact timeframe, recovering from approximately $140.0 million in departures recorded during the prior week, thereby counterbalancing earlier withdrawals.
Monday drove most of the week’s inflows
The bitcoin funds had accumulated merely $6.2 million in deposits the preceding week, supported entirely by a $433.0 million surge on Friday. Throughout the subsequent week, the vast majority of capital arrived on the opening day, building on Friday’s momentum.
The 12 exchange-traded Bitcoin funds monitored by SoSoValue captured $999.0 million on Monday, marking their highest single-day intake since October 6, 2025, and representing the ninth-largest daily volume since these offerings debuted in January 2024.
Nonetheless, daily inflows experienced a consecutive decline during every succeeding trading session. The funds secured $714.7 million on Tuesday, $347.0 million on Wednesday, $190.6 million on Thursday, and $134.5 million on Friday. Friday signified the seventh continuous session of positive intake for the funds, generating a seven-day sequence valued at $3.0 billion originating on September 17.
BlackRock’s IBIT maintained its position as the market leader regarding assets under management (AUM), pacing the sector with $1.2 billion in net new capital based on the reporting data. This represented IBIT’s second-highest weekly capture following October 2025, trailing only the $1.3 billion gathered during the week closing on August 21.
Fidelity’s FBTC, holding the secondary spot for AUM and volume market share, acquired $701.7 million, marking its strongest weekly performance since the week beginning September 8, 2025. Ark and 21Shares’ ARKB secured $294.7 million, with nearly the entirety arriving on Monday.
Morgan Stanley’s MSBT generated $203.3 million, logging its most successful week since its introduction in April. The vehicle’s prior weekly peak reached $71.1 million, established in the middle of April.
Analysts point to Treasury buybacks
Aggregate net deposits since inception presently stand at $57.6 billion, alongside cumulative net assets valued at $108.4 billion as of Friday.
Bloomberg exchange-traded fund specialist Eric Balchunas highlighted the reversal through a Wednesday publication on X. He associated the “$4.6b tsunami of cash” directly with the Treasury Department’s strategy to expand repurchases of long-maturity government bonds.
Nate Geraci, who serves as president at NovaDius Wealth Management, commented in a Saturday statement that these funds have attracted an aggregate $5.3 billion since the Treasury initially unveiled the repurchase program. Geraci noted, “Monday’s $1bil inflow was 9th largest ever.”
Trading turnover registered at $15.0 billion throughout the week, sliding from $16.2 billion during the preceding weekly period, according to metrics compiled by The Block.
Ether funds likewise rebound
Spot Ethereum exchange-traded funds brought in $270.0 million on Monday, marking their highest daily intake since October 7, 2025, thereby mirroring the robust activity seen in Bitcoin counterparts. The 11 publicly listed funds subsequently added figures ranging between $66.0 million and $162.3 million across each of the subsequent four sessions.
BlackRock’s ETHA secured the top position with $326.2 million for the week, trailed by Fidelity’s FETH at $174.0 million and Grayscale’s Ethereum Mini Trust at $100.3 million. BlackRock’s ETHB accumulated $47.5 million, which featured $31.9 million captured on Friday.
Last week’s aggregate represented the highest performance for Ethereum vehicles since the week ending August 28, during which they collected $824.4 million. These products currently show a year-to-date gain near $1.6 billion, backed by $17.8 billion in net assets and $13.9 billion in total lifetime deposits since launch.
Ethereum ETF trading turnover declined to $4.8 billion from $6.9 billion recorded during the prior week, based on data provided by The Block.
Solana funds set a daily record

Solana vehicles gathered $188.2 million across the week, placing second behind only their launch week total of $199.2 million.
