Bitcoin ETF Daily Inflows Sink 80%, Yet Weekly Total Hits Largest Since October

A seven-day winning streak pushed 2026 cumulative flows into positive territory even as single-day demand cooled sharply.

Spot Bitcoin exchange-traded funds logged a seven-day streak of net inflows this week, according to data cited by Decrypt and The Block. The run culminated in a weekly total of $2.4 billion, the largest since October, The Block reported.

That weekly figure carries added significance because it flipped cumulative Bitcoin ETF flows for 2026 from negative to positive, Decrypt reported. Investors had pulled more money from these funds than they had added earlier in the year, making the turnaround a notable shift in sentiment among ETF allocators.

At the same time, Cointribune reported that daily inflows into the funds plunged roughly 80% compared with the prior session. The two data points are not necessarily in conflict. A steep single-day pullback can still sit inside a strong multi-day run if earlier sessions in the same week carried outsized buying. Weekly totals smooth over daily volatility that can swing sharply based on macro news, trading hours, or individual fund flows.

Spot Bitcoin ETFs have become one of the primary channels through which institutional and retail investors gain regulated exposure to Bitcoin without directly holding the asset. Since their launch, cumulative flows into these products have served as a widely watched gauge of demand, alongside metrics like assets under management and daily trading volume.
