Bitcoin ETFs Notch Seven-Day Winning Streak as 2026 Flows Turn Green

Less than two weeks ago, Bitcoin ETF investors were heading for the exits. Now they’re piling back in.

U.S. spot Bitcoin ETFs took in $134.5 million on Friday, extending their inflow streak to seven straight trading days, according to Decrypt’s Bitcoin ETF tracker. The run, which began Sept. 17, has pulled in about $2.98 billion.

That’s a sharp reversal from mid-September. The funds shed $450.4 million on Sept. 15, their worst day since June, after the Senate’s failed cloture vote on the Clarity Act. They lost another $295.9 million the next day.

Then the tide turned. Inflows since have outpaced those back-to-back losses roughly fourfold.

Bitcoin ETFs are exchange-traded funds that hold actual Bitcoin, letting investors gain exposure through a regular brokerage account, circumventing crypto exchanges, wallets, and seed phrases altogether. Their daily flows have become a closely watched barometer of institutional appetite.

The biggest boost came Sept. 21, when the funds took in nearly $1 billion, their best day since October 2025. As Decrypt reported Tuesday, that surge helped lift Bitcoin above the average ETF holder’s cost basis of $81,722, a figure estimated by Bloomberg analyst James Seyffart. That put the typical fund investor back in profit for the first time since January.

The streak has also rewritten the year’s scorecard. Through Thursday, the funds had taken in a net $886.8 million in 2026, according to Farside Investors data. That’s a roughly $6.6 billion swing from July 13, when they sat $5.69 billion in the red. Friday’s inflow would push the total past $1 billion, though tallies vary by tracker. Bloomberg put year-to-date flows at about $320 million earlier this week.

Cumulative net inflows since the funds launched now stand at $58.0 billion, according to Decrypt’s tracker. Total net assets sit at $108.42 billion, with Bitcoin trading at around $84,020.

There’s still ground to cover. Last year, the funds drew $21.35 billion, per Farside. Matching that would take roughly $300 million a day through December, a pace this streak has comfortably topped on average.
