BlackRock's iShares Bitcoin Trust (IBIT) experienced a sharp reversal in flows during late October through mid-November 2026, recording net outflows of approximately $2.1 billion to $2.35 billion over that period. Despite the redemptions, the fund remained in positive territory for the year with approximately $2.45 billion in net inflows as of mid-November.
The outflow window included an 11-day consecutive streak of redemptions that ended around November 13. During this period, Bitcoin traded below the $68,000 to $70,000 range.
Broader ETF Market Weakness
US spot Bitcoin ETFs as a group recorded around $1.42 billion in net outflows for 2026 through mid-November, with IBIT accounting for the majority of those redemptions. The disparity indicates that smaller issuers in the category experienced more significant capital outflows than the largest fund.
Scale Since Launch
US spot Bitcoin ETFs launched in January 2024, providing institutional and retail investors with exchange-traded access to Bitcoin without requiring direct use of crypto exchanges or hardware wallets. Cumulative net inflows into the category since launch exceeded roughly $54.7 billion, with IBIT responsible for most of that total.
IBIT's assets under management stood between approximately $53 billion and $56 billion as of mid-November 2026.
Flow Volatility and Market Context
Weekly and monthly flow swings across spot Bitcoin ETFs have frequently exceeded $1 billion. Investors may want to treat single-week flow data with caution given the frequency and magnitude of such movements. An extended streak of consecutive outflow days similar to the 11-day run would signal more durable caution in the market.
