U.S. spot Bitcoin ETFs are having a very good month. They took in $2.95 billion over the past 30 days, according to SoSoValue, and extended their inflow streak to eight straight trading days on Monday.
Two days after Bitcoin funds lost $450.4 million when the Clarity Act failed a Senate vote, the streak started on Sept. 17. That single-day outflow was the largest since June 24, and it happened on Sept. 15, the day the Senate voted 49-50 against advancing the bill, which needed 60 votes to pass.
The Numbers Behind the Streak
The eight-day run has been driven by strong days mixed with quieter ones. Monday itself was relatively quiet: $31.07 million in net inflows, the weakest day of the streak. BlackRock’s IBIT fund took in $54.84 million, but Grayscale’s GBTC lost $23.19 million and Fidelity’s FBTC shed $10.90 million.
Before the streak began, the week was difficult. On Sept. 15, Bitcoin ETFs lost $450.4 million, while Ethereum ETFs lost an additional $142.3 million on the same day. For the entire week, the total inflow amounted to just $6.2 million, marking the smallest weekly inflow in 141 weeks.
The funds drew buyers back quickly. On Sept. 21, they took in nearly $1 billion, the strongest single day for the funds since October 2025. A further $715 million arrived on Sept. 22. From there, the rate slowed down, dropping to $347 million on Sept. 23, $191 million on Sept. 24, and $134 million on Sept. 25, adding up to roughly $2.4 billion for the week. That weekly figure marks the largest since October 2025.
On Monday, Bitcoin climbed past the average cost basis of an ETF holder, which sits at $81,722. That brought the typical fund investor back into profit for the first time since January. The coin itself was trading above $84,000 at the time.
What the Other Coins Are Doing
Other digital assets aren’t being left behind when it comes to these investment vehicles either. Ethereum ETFs pulled in $982.5 million over 30 days and added $17.1 million on Monday, according to SoSoValue. Solana funds drew in $278.2 million over the month, while XRP funds brought in $127.05 million.
| Coin | 30-Day Inflows |
|---|---|
| Bitcoin | $2.95 billion |
| Ethereum | $982.5 million |
| Solana | $278.2 million |
| XRP | $127.05 million |
A Ninth Straight Day Would Match August
Nine straight days of inflows would equal the August stretch. The nine-day run ended on Aug. 28, when the funds lost $201.9 million after Federal Reserve Chair Kevin Warsh spoke at Jackson Hole. Investors were guessing what the Fed would do next with interest rates.
The streak remains intact through the quiet Monday, even as the daily numbers have cooled since the Sept. 21 peak.
What This Means for Investors
The string of days shows that investors keep putting money back into Bitcoin ETFs despite recent weeks of price swings. Even though the daily inflows have cooled since the Sept. 21 peak, the $2.95 billion added over 30 days stands as a mark of faith in these funds.
It’s worth remembering how the August stretch compared. That nine-day run came to an end on Aug. 28, when $201.9 million left the funds following Kevin Warsh’s remarks at Jackson Hole. The present streak has managed to avoid that particular conclusion so far.
A broader look shows the ETF market for crypto has turned into a major route for investors. Bitcoin ETFs have already gathered $2.95 billion over 30 days, while the funds tied to Ethereum, Solana, and XRP have each brought in hundreds of millions.
Whether the streak continues depends on the coming days.
