The US spot Bitcoin ETF market just had its worst month on record. June 2026 closed with $4.06 billion in net outflows, surpassing the previous monthly low of $3.56 billion set in February 2025.
The month featured seven consecutive days of net redemptions at one point, with a single-day peak outflow of $696.3 million.
BlackRock’s IBIT absorbed roughly $1.3 billion in withdrawals across just five days.
By the close of June, total assets under management across US spot Bitcoin ETFs sat at $72.82 billion.
Daily outflows continued through the final week of the month. June 29 alone saw $231 million in net redemptions.
Bitcoin’s price dropped below $60,000 during June, hitting a year-to-date low of $58,190. That represents a decline of nearly 30% from where Bitcoin started 2026.
June did not happen in a vacuum. A 12-to-13 day outflow streak that began in mid-May and stretched into early June had already totaled around $4.4 billion before the calendar officially flipped.
2026 also marked the first calendar year in which net flows for US spot Bitcoin ETFs have turned negative overall. These products launched in January 2024.
Even with the dollar outflows at record levels, Bitcoin holdings within ETF vehicles remained close to historical peaks when measured in BTC terms.
Corporate treasury buyers continued purchasing Bitcoin during the June dip, which provides some counterbalancing demand that does not show up in ETF flow data.
BlackRock’s IBIT remains the dominant product by assets despite the outflows. The concentration of redemptions in IBIT over that five-day stretch is partly a function of its size.
