Summary
BlackRock's iShares Bitcoin Trust (IBIT) recorded net outflows in every session between November 2 and 6, 2026, totaling $1.21 billion, according to Farside Investors' daily flow table checked on November 7. Over the same period, the rest of the U.S. spot Bitcoin ETF market combined recorded a net outflow of $72.2 million, leaving the sector at $1.28 billion negative for the week. IBIT therefore accounted for 94.4% of the net weekly figure. Based on iShares data, IBIT held $60.7 billion in net assets on November 6, making the weekly outflow about 2% of the fund. The streak began on October 30, with Friday marking IBIT's sixth consecutive session of net outflows.
The week's flows were uneven. Monday and Tuesday saw IBIT lose $500.3 million combined, while other funds moved by no more than $20.6 million on either day. Wednesday was the only day of net sector inflow, at $74.6 million positive, as Fidelity's FBTC took in $236.7 million even as IBIT lost $201.2 million. On Thursday, Fidelity's FBTC posted a $199.9 million outflow, the largest of any fund that session, while Grayscale's GBTC lost $49.9 million. Non-IBIT withdrawals reached $325.2 million, and the sector's $430.2 million outflow was the week's largest. Friday returned to the pattern of IBIT dominance, with IBIT losing $403 million, or 98% of the sector's $411.9 million outflow.
Thursday's sector exit coincided with a sharp Bitcoin price decline. Fortune's price check placed BTC at about $76,024 on Friday morning, 5.2% below the prior day's $80,221. Farside's flow data records timing but not cause, so it cannot establish whether price declines drove redemptions or the reverse.
In Ethereum funds, Farside data showed $93.3 million leaving U.S. Ether ETFs on Friday, with $90.8 million from BlackRock's ETHA. Per the report, IBIT is a passive trust that tracks Bitcoin's price, and the outflows reflect shareholder decisions rather than a bearish call by BlackRock. Redemptions moved through authorized participants in baskets of 22.64 BTC, worth about $1.71 million each on November 6 according to iShares. The publication notes that the flow data does not show whether redeemed bitcoin was sold or held, and that the trust's share price closed Thursday within 0.02% of its net asset value.
