US-listed Bitcoin ETFs face worst month of withdrawals since launch

Two years ago, the arrival of spot Bitcoin ETFs on US exchanges was supposed to herald a new era of steady institutional demand. June 2026 is telling a very different story.

US-listed spot Bitcoin ETFs have recorded approximately $4.06 billion in net outflows this month, according to data from SoSoValue. That makes June the worst month for withdrawals since the funds first began trading in January 2024, eclipsing the previous record of $3.56 billion set in February 2025.

The numbers behind the exodus

From May 15 through June 3, Bitcoin ETFs posted 13 consecutive days of net outflows, the longest such streak on record. During that stretch alone, investors pulled roughly $4.4 billion from the funds.

The weekly pace has been punishing. For the week ending June 6, net outflows hit $1.72 billion, the largest single-week figure since February 2025. Over the preceding four weeks, cumulative withdrawals reached $5.4 billion. Stretch that to six weeks and the total climbs to $5.94 billion.

No fund has been immune, but BlackRock’s iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets, took the hardest hit. IBIT saw approximately $860 million exit in a single reported week.

What’s driving the selling

Bitcoin’s price during this period has hovered between $58,000 and $60,000. The combined assets under management across all US spot Bitcoin ETFs have fallen from around $104 billion, a decline driven by both the outflows themselves and the shrinking value of the remaining Bitcoin holdings.

Why this matters beyond Bitcoin

Spot Bitcoin ETFs fundamentally changed Bitcoin’s market structure when they launched. They became the primary channel through which new capital, especially institutional capital, entered the Bitcoin market. During periods of strong inflows in 2024 and early 2025, these funds were absorbing more Bitcoin daily than miners could produce.

The February 2025 outflow episode provides a useful comparison point. Back then, $3.56 billion left the funds over the course of a month. June’s $4.06 billion figure is 14% larger, and it arrived after an extended multi-week selling streak that started before the month even began.

The AUM decline from $104 billion also raises practical questions about fee revenue for issuers and whether smaller funds in the space can remain economically viable if the trend persists. BlackRock and Fidelity can weather a few rough months. Some of the smaller entrants with thinner margins and lower asset bases may not have that luxury.
