US-listed spot Bitcoin exchange-traded funds (ETFs) experienced a record $4.5 billion in net outflows during June, marking their worst month since their launch. This figure significantly surpasses previous monthly withdrawal records.
BlackRock's iShares Bitcoin Trust (IBIT), the largest fund by assets, accounted for approximately $3.55 billion of these outflows. This trend contributed to a decrease in total assets managed by these ETFs, which fell to about $71 billion from $83 billion at the beginning of the month.
Analysts suggest that events such as the SpaceX IPO and Federal Reserve comments indicating potential rate hikes may have prompted institutions to reduce exposure to volatile assets like Bitcoin. These outflows follow $2.43 billion in net redemptions in May, bringing the total for the two-month period to nearly $6.5 billion.
On a year-to-date basis, net outflows for the first half of 2026 have reached approximately $5.5 billion. This reduced institutional demand has coincided with a roughly 30% decline in Bitcoin's price during the first half of the year.
