Bitcoin ETFs Extend Inflow Streak to Eight Days with $2.95 Billion Monthly Gain

Bitcoin ETFs are having a very good month, all things considered. U.S. funds pulled in $2.95 billion over the past 30 days, according to SoSoValue, and extended their inflow streak to eight straight trading days on Monday.

Monday itself was relatively quiet: $31.07 million in net inflows, the weakest day of the streak. BlackRock once again pulled its weight, with its IBIT fund taking in $54.84 million, but Grayscale's GBTC lost $23.19 million and Fidelity's FBTC shed $10.90 million.

The current run of green days for Bitcoin ETFs started on Sept. 17, right after the ugliest stretch in months. On Sept. 15, Bitcoin ETFs lost $450.4 million, their biggest one-day outflow since June 24, coinciding with the US Senate voting 49-50 against advancing the Clarity Act. It needed 60 votes, and it didn’t get there. Etherum ETFs lost another $142.3 million that day.

That whole week was ugly. Bitcoin ETFs netted just $6.2 million, their smallest weekly inflow in 141 weeks.

Then buyers came back fast. Sept. 21 brought in nearly $1 billion, the best day for the funds since October 2025. Another $715 million followed on Sept. 22.

Then the pace cooled. Flows fell to $347 million on Sept. 23, $191 million on Sept. 24, and $134 million on Sept. 25, for a weekly total of about $2.4 billion. That is the biggest weekly haul since October 2025.

The rally also lifted Bitcoin above the average ETF holder's cost basis of $81,722, putting the typical fund investor back in profit for the first time since January. Bitcoin was back above $84,000 on Monday.

The streak is long, but not a record for the summer. A nine-day run ended on Aug. 28, when the funds saw $201.9 million in outflows after Federal Reserve Chair Kevin Warsh spoke at Jackson Hole, moving the market as traders attempt to guess at what the Fed does next with interest rates.

Bitcoin isn't the only one getting money via these investment vehicles either. Ethereum ETFs added $982.5 million over 30 days and $17.1 million on Monday, per SoSoValue. Solana funds took in $278.2 million over the month and XRP funds brought in $127.05 million.

A ninth straight day of inflows would match the August run.
