The BlackRock iShares Bitcoin Trust (IBIT) recorded $2.43Bn in net outflows over nine consecutive sessions in May 2026, culminating in a $1.26Bn dark-pool block sale on May 26, marking the largest single-day redemption event in the fund’s history since its January 2024 launch.
On-chain data simultaneously confirmed the transfer of approximately 6,005 BTC, equivalent to roughly $403M at prevailing prices, from IBIT-linked custody wallets to Coinbase Prime, providing direct on-chain confirmation of the redemption mechanics underlying the headline outflow figure.
The nine-session streak erases a substantial portion of the roughly $3Bn IBIT absorbed in April alone, when spot Bitcoin ETF inflows hit one of their strongest consecutive streaks since October 2025.
That reversal, combined with the scale of the BTC transfer to an exchange custody platform, pushed Bitcoin into a risk-off pricing regime and added measurable sell-side liquidity to spot market order books during an already-pressured macro window.

The BlackRock IBIT fund had approximately 660,000 to 670,000 BTC during the recent outflow period, translating to an AUM of $44Bn to $46Bn at mid-2026 prices.
The $2.43Bn outflow from Bitcoin ETFs represents about 5% to 5.5% of fund assets, indicating a macro signal rather than just routine redemptions.
The previous record for a single-session outflow was $649M in January, making the May 26 block sale nearly double that figure.
Cross-fund data from CoinGlass shows that the outflow pressure affected not just IBIT, but also Fidelity’s FBTC, ARK Invest’s ARKB, and Grayscale’s GBTC, indicating a broader institutional de-risking rather than issues with specific funds.
Year-to-date, US spot Bitcoin ETFs still saw net positive flows of nearly $2Bn entering June, with cumulative inflows around $58Bn to $59Bn.
Although May’s outflows impacted that figure, they didn’t reverse the overall structural long position established by institutional crypto allocators in 2024 and 2025.
SOURCE: CoinGlassA nine-session outflow streak occurred amid high US Treasury yields and a Fed stance perceived as constraining for risk assets, causing Bitcoin’s price to drop below previous consolidation levels.
Institutional investors reduced exposure to high-volatility assets, including Bitcoin ETFs, resulting in $1.67Bn in outflows from European crypto exchange-traded products from May 25 to May 29.
This trend indicates a global institutional repositioning beyond BlackRock and the other US ETFs. Meanwhile, newly launched XRP spot ETFs saw $132M in net inflows with no outflow days, suggesting a shift within the crypto space rather than an overall exit.
Bitcoin’s price has hovered just above $63,000, a critical support level that distinguishes between consolidation and a deeper downturn.
A drop below this level could trigger more selling, potentially testing $60,000, where long-term buyers typically step in. The bearish scenario involves ongoing institutional outflows, rising real yields, and a lack of support at $65,000.
Conversely, the bullish outlook hinges on a reversal after prolonged outflows, perhaps sparked by favorable CPI data or dovish Fed signals, especially as Bitcoin ETF assets remain strong.
The likely near-term scenario is sideways trading between $62,000 and $65,000, with market direction awaiting clarification from macroeconomic indicators.
