Bitcoin ETFs record seven-day winning streak with nearly $3B in inflows, reversing 2026 year-to-date losses.
Macro & Markets ·
U.S. spot Bitcoin ETFs experienced a sustained rally, drawing approximately $2.98 billion across seven consecutive trading sessions beginning September 17. This inflow reversal came after the funds recorded substantial outflows totaling $746.3 million on September 15 and 16 following a failed Senate cloture vote on the Clarity Act. The recovery swiftly eclipsed those losses, with the streak's most robust performance occurring September 21, when the funds attracted nearly $1 billion in a single session.
The seven-day run fundamentally shifted 2026's cumulative flow picture. Year-to-date inflows flipped to positive $886.8 million through Thursday, representing a sharp departure from July's $5.69 billion deficit. Daily inflows during the streak averaged roughly $425 million, substantially surpassing the typical pace needed to match 2025's annual total of $21.35 billion. Bitcoin's movement above the estimated cost basis of typical ETF holders during this period restored profitability to positions held since January.
The mechanics underlying daily ETF flows remain contested across data providers, with tracker variations producing different year-to-date totals. Total net assets in these funds currently stand at $108.42 billion, while cumulative net inflows since inception reached $58.0 billion. Whether this momentum sustains depends on institutional appetite over the remainder of the year.
