Summary
US spot Bitcoin exchange-traded funds have attracted their strongest three-week inflow period of 2026, drawing $3.8 billion in cumulative net inflows. The week ending Friday saw inflows of $986.9 million, according to SoSoValue data, marking a significant recovery from sustained outflow periods earlier in the year. This rebound reflects renewed institutional interest in Bitcoin exposure through regulated fund vehicles, with total net assets across spot Bitcoin ETFs now standing at $101.3 billion as of Friday, having briefly peaked at $103.3 billion the previous trading day.
The rally comes amid Bitcoin trading near $80,000, though price momentum moderated through the week. Daily inflows slowed considerably on Friday, with only $174.6 million in net inflows recorded compared to $731 million on Thursday, as Bitcoin declined from approximately $81,200 to below $79,000 before settling at $79,716. This price pullback coincided with a notable deceleration in ETF purchasing activity, suggesting price-sensitive institutional flows.
BlackRock's iShares Bitcoin Trust (IBIT), the market's largest spot Bitcoin ETF by assets, dominated inflow activity by capturing $117.4 million on Friday alone, representing approximately 67% of total daily net inflows. Fidelity's Wise Origin Bitcoin Fund (FBTC) was the only other fund to record meaningful inflows at $57.2 million, while all remaining US spot Bitcoin ETFs recorded flat flows. This concentration underscores the continued dominance of the largest, most liquid Bitcoin fund products among institutional allocators.
The three-week inflow streak represents a dramatic reversal from conditions that prevailed earlier in 2026, when spot Bitcoin ETFs experienced five consecutive weeks of outflows totaling approximately $3.8 billion. Despite this recent recovery, year-to-date net flows remain roughly $1 billion negative, indicating that cumulative 2026 flows have not yet turned positive. Notably, Bitcoin ETF strength is occurring in isolation within the crypto ETF complex—while Bitcoin ETF inflows increased 7% week-over-week, inflows into US spot Ether ETFs declined 74% to $218.4 million and XRP ETF inflows dropped 83% to $19 million, signaling a flight-to-quality dynamic favoring the largest cryptocurrency asset.
