U.S. spot Bitcoin ETFs took in $134.5 million on Friday, extending their inflow streak to seven consecutive trading days and pushing year-to-date flows back into positive territory, according to Decrypt's Bitcoin ETF tracker. The run, which began Sept. 17, has pulled in about $2.98 billion.

The streak marks a sharp reversal from mid-September, when the funds were bleeding cash. They shed $450.4 million on Sept. 15 — their worst single day since June — after the Senate's failed cloture vote on the Clarity Act, a market-structure bill that would divide oversight of digital assets between the Securities and Exchange Commission and the Commodity Futures Trading Commission. Cloture, which requires 60 votes, is the Senate's mechanism for cutting off debate and moving a bill forward. The funds then lost another $295.9 million the following day, for combined outflows of $746.3 million across the two sessions. Inflows since then have outpaced those back-to-back losses roughly fourfold.

Bitcoin ETFs are exchange-traded funds that hold actual Bitcoin, allowing investors to gain exposure through a regular brokerage account and circumvent crypto exchanges, wallets, and seed phrases altogether. Their daily flows have become a closely watched barometer of institutional appetite, with net creations and redemptions tracked each trading session.

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 — the average price at which coins held through the funds were acquired — 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 — a swing of roughly $6.6 billion from July 13, when they sat $5.69 billion the red. Friday's inflow would push the year-to-date total past $1 billion, though tallies vary by tracker depending on methodology; Bloomberg put 2026 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 is still ground to cover. The funds drew $21.35 billion last year, per Farside, and matching that total would take roughly $300 million a day through December. The current streak has averaged roughly $425 million a day, comfortably topping that pace.
