The US spot Bitcoin ETF market has experienced a significant downturn, marking June 2026 as its worst month on record with net outflows reaching $4.06 billion. This new low eclipses the previous record of $3.56 billion in outflows set in February 2025. Notably, the month included a troubling period of seven consecutive days with net redemptions, culminating in a single-day peak outflow of $696.3 million.
The largest of the US Bitcoin ETFs, BlackRock’s IBIT, was particularly affected, bearing approximately $1.3 billion in withdrawals over just five days. By the end of June, the total assets under management across all US spot Bitcoin ETFs settled at $72.82 billion, a stark reflection of the panic that rippled through the market.
Daily outflows persisted throughout the final week of June, with June 29 alone recording net redemptions of $231 million. This negative sentiment coincided with a steep decline in Bitcoin’s price, which dropped below the $60,000 mark, hitting a year-to-date low of $58,190. This represents nearly a 30% decrease from Bitcoin’s price at the start of 2026.
The challenges faced in June did not arise suddenly. A prior streak of outflows, starting from mid-May and extending into early June, had already totaled around $4.4 billion before the month began. Alarmingly, 2026 has also marked the first calendar year in which net flows for US spot Bitcoin ETFs have turned negative overall, following their launch in January 2024.
Despite the staggering dollar outflows, Bitcoin holdings within ETF vehicles remained near historical highs when assessed in BTC terms. This indicates that while redemptions are occurring, the underlying asset values retained within the ETFs are still substantial. Additionally, corporate treasury buyers have been acquiring Bitcoin during this dip, providing a form of counterbalancing demand that is not reflected in the ETF flow data.
Though the outflows have been significant, BlackRock’s IBIT maintains its position as the leading product by assets, highlighting that the concentration of redemptions over that five-day period is largely a result of its market size. The persistence of adverse flows raises questions about investor confidence in the space, as stakeholders assess the broader implications for the future of Bitcoin ETFs.
