U.S. Spot Bitcoin ETFs Record Largest Monthly Inflow in 13 Months

U.S. spot Bitcoin exchange-traded funds (ETFs) recorded $3.54 billion in net inflows during August, marking the largest monthly intake since July 2024, according to data shared by Galaxy Digital’s head of research, Alex Thorn. The rebound signals renewed institutional interest in the asset class, although the products still face a net outflow position for the year to date.

August Inflows Highlight Shift in Investor Sentiment

The August figure represents a significant turnaround from earlier months, when spot Bitcoin ETFs experienced persistent outflows. According to Galaxy Research, cumulative net inflows for the year stand at $21.3 billion, but after accounting for prior-year flows, the year-to-date net figure is negative $1.7 billion. This means that despite the strong August performance, the products have not fully recovered from earlier withdrawals.

For context, annual net inflows reached $35.2 billion in 2024, the first year of trading for these funds. The 2025 figure, while still substantial, trails that pace. Analysts attribute the recent surge to a mix of macroeconomic factors, including expectations of interest rate cuts and a stabilizing regulatory environment for digital assets.
