US spot Bitcoin ETFs have hemorrhaged $4.06 billion in net outflows this month, making June 2026 the single worst month for the products since they debuted in January 2024.
The numbers tell a brutal story
The outflow wave included seven consecutive days of net withdrawals, with single-day figures hitting $696.3 million and $445 million at their peaks.
BlackRock’s iShares Bitcoin Trust, better known by its ticker IBIT, bore a disproportionate share of the pain. The world’s largest asset manager saw roughly $1.3 billion leave IBIT in just one concentrated five-day stretch.
Total assets across all US spot Bitcoin ETFs have now declined to approximately $72.82 billion.
