U.S. spot Bitcoin exchange-traded funds absorbed $2.95 billion in net inflows over the past 30 days, according to flow data from SoSoValue, extending a run of positive days to eight consecutive trading sessions as of Monday.

Monday itself was the quietest session of the streak. Funds took in a net $31.07 million. BlackRock's iShares Bitcoin Trust (IBIT) accounted for $54.84 million of gross demand, but the day's total was dragged down by outflows from two of the largest products: Grayscale's GBTC shed $23.19 million and Fidelity's FBTC lost $10.90 million.

The current streak began on Sept. 17, two days after the segment's roughest session in months. On Sept. 15, Bitcoin ETFs bled $450.4 million — the largest single-day outflow since June 24 — coinciding with the U.S. Senate's 49-50 vote against advancing the Clarity Act, the market-structure bill that failed to reach the 60-vote threshold needed for cloture. Ethereum ETFs lost a further $142.3 million the same day.

That week was the weakest in years for the category. Bitcoin funds netted just $6.2 million in total, the smallest weekly inflow in 141 weeks, per SoSoValue.

Buyers returned abruptly. Sept. 21 brought nearly $1 billion into the funds, the best single day since October 2025, followed by another $715 million on Sept. 22. The pace then cooled steadily: $347 million on Sept. 23, $191 million on Sept. 24 and $134 million on Sept. 25. The week closed with roughly $2.4 billion in net inflows — the largest weekly haul since October 2025.

The rebound has operational significance for ETF issuers beyond flow headlines. Bitcoin's price moved back above the average ETF holder's cost basis of $81,722, placing the typical fund investor in profit for the first time since January. Bitcoin traded above $84,000 on Monday.

The eight-day streak is long, but not the longest of the summer. A nine-day run ended on Aug. 28, when the funds recorded $201.9 million in outflows after Federal Reserve Chair Kevin Warsh spoke at Jackson Hole, a reminder that macro policy signals remain the primary circuit breaker for crypto fund flows as traders position around the Fed's next rate decision.

Bitcoin is not the only asset drawing capital through the ETF wrapper. Ethereum funds added $982.5 million over the trailing 30 days, including $17.1 million on Monday. Solana ETFs took in $278.2 million over the month, and XRP funds brought in $127.05 million, per SoSoValue.

A ninth consecutive day of net inflows would match the August run. Whether the streak survives depends largely on the next leg of Federal Reserve communication and on whether Congress revisits the Clarity Act, whose failed cloture vote triggered the segment's worst outflow day in nearly three months.
