U.S. spot Bitcoin ETFs attracted $134.5 million on Friday, continuing a seven-day inflow streak that has accumulated approximately $2.98 billion since Sept. 17. This surge follows significant outflows of $746.3 million on Sept. 15 and 16, which occurred after the Senate failed to pass the Clarity Act. The recent momentum has turned year-to-date flows positive at $886.8 million through Thursday, according to Farside Investors, marking a substantial recovery from a $5.69 billion deficit recorded in July.
The strongest single day of this period was Sept. 21, when funds took in nearly $1 billion, their best performance since October 2025. This influx helped lift Bitcoin’s price above the average ETF holder’s cost basis of $81,722, estimated by Bloomberg analyst James Seyffart, returning typical investors to profit for the first time since January. Cumulative net inflows since the products launched now stand at $58.0 billion, with total net assets reaching $108.42 billion while Bitcoin trades around $84,020. To match last year’s $21.35 billion in inflows, funds would need to average roughly $300 million daily through December.
The reversal from post-legislative failure outflows to a sustained inflow streak demonstrates the resilience of institutional demand for regulated crypto exposure despite regulatory uncertainty. The rapid accumulation of $2.98 billion in just one week suggests that market participants are prioritizing asset allocation over short-term legislative setbacks, viewing the ETF structure as a stable vehicle for Bitcoin access regardless of immediate policy outcomes. This behavior indicates that the initial shock of the Clarity Act’s failure has been absorbed, replaced by a focus on price appreciation and portfolio rebalancing.
However, the gap between current year-to-date totals and last year’s $21.35 billion highlights the volatility inherent in these flows. While the recent streak is impressive, sustaining the pace required to match previous annual records demands consistent daily volumes that may be difficult to maintain without further catalysts. Market observers should monitor whether this inflow pattern persists or if it represents a temporary rebound driven by technical factors, such as the return to profitability for average holders, rather than long-term structural adoption.
