Bitcoin ETFs extend seven-day inflow streak as 2026 flows turn positive

U.S. spot Bitcoin ETFs took in $134.5 million on Friday and extended their inflow streak to seven straight trading days. The streak began on Sept. 17. The funds have brought in about $2.98 billion during the streak. Farside Investors data showed net inflows of $886.8 million in 2026 through Thursday. The funds had a $5.69 billion deficit in July. Friday's inflow would push the 2026 total past $1 billion, although tallies vary by tracker. Bloomberg estimated 2026 flows at about $320 million earlier this week. The funds lost $450.4 million on Sept. 15 after the Senate's failed cloture vote on the Clarity Act. They lost another $295.9 million the next day. Inflows since then have exceeded those two losses by about four times. The funds took in nearly $1 billion on Sept. 21. That was their best day since October 2025. The surge lifted Bitcoin above the average ETF holder's estimated cost basis of $81,722, according to Bloomberg analyst James Seyffart. The typical fund investor returned to profit for the first time since January. Cumulative net inflows since the funds launched stand at $58.0 billion. Total net assets stand at $108.42 billion. Bitcoin is trading at around $84,020. The funds took in $21.35 billion last year, according to Farside. Matching that amount would require roughly $300 million a day through December.
