Bitcoin ETFs' $6.3B Q3 Surge Masks $5.4B First-Half Outflow

Bitcoin exchange-traded funds (ETFs) experienced a substantial inflow of $6.3 billion in the third quarter of 2026, according to SoSoValue. However, this influx masks a significant outflow of $5.4 billion from these funds in the first half of the year.

The combined net assets of these funds now stand at $109.3 billion, down 14.6% from their peak of $128 billion in mid-January. Bitcoin's price also played a role in the decline, trading about 5% below its starting point for 2026.

The funds experienced a seven-week period of inflows in the spring, but selling outside that timeframe was more substantial. The most significant selling took place early in the year, with a net outflow of $818 million in late January, shortly after the assets peaked.

The $6.3 billion inflow in the third quarter, mainly from August and September, helped refill most of the gap left by the first-half outflows. The year-to-date total of $985 million includes this influx, but the first half ended with around $5.4 billion in net outflows.
