Bitcoin medallion beside a concentrated institutional flow channel

BlackRock’s IBIT Drove 94% of a $1.28 Billion Bitcoin ETF Exit

One fund did almost all the damage in the latest Bitcoin ETF selloff.

U.S. spot Bitcoin ETFs lost about $1.28 billion during the completed November 2-6 trading week. Roughly $1.21 billion of that total came from BlackRock’s iShares Bitcoin Trust, better known as IBIT.

That means IBIT accounted for approximately 94% of the category’s net withdrawals.

The concentration matters. A billion-dollar headline can look like the entire institutional market is rushing for the exit.

The fund-by-fund numbers tell a narrower story: the pressure was severe, but it was heavily concentrated in the largest product.

CryptoSlate reports that the 12 U.S. funds tracked by Farside Investors recorded $1.282 billion in net outflows for the week. IBIT lost about $1.2095 billion, while Fidelity’s FBTC managed to finish the same period with a positive net flow.

The rest of the complex was not healthy enough to erase IBIT’s impact. Excluding BlackRock’s fund, the remaining products were still negative as a group.

But the scale was radically different, and Fidelity’s positive week showed that the selling was not uniform across every major issuer.

That is the key distinction for investors watching the next round of data. A broad institutional retreat and a concentrated redemption wave can produce the same ugly weekly total, but they do not carry the same signal.

Farside Investors shows that Friday alone ended with $411.9 million in net withdrawals. IBIT lost $403 million that day, while Fidelity’s fund took in $42.8 million.

Bitwise’s BITB, ARK and 21Shares’ ARKB, and Grayscale’s GBTC also posted smaller outflows.

The weekly damage was spread across four losing sessions. Wednesday was the only positive day, and its inflow was not large enough to offset the exits surrounding it.

Bitcoin was trading near $75,700 as the week closed, while the broader risk backdrop remained uneasy.

The positioning data adds another layer of caution.

Glassnode says large traders on Hyperliquid recently turned net short after seven months of net-long positioning. Their short exposure has now reached its highest level since October 2025.

ETF redemptions and leveraged futures positioning are different markets. They should not be treated as one trade or one coordinated bet.

Together, however, they show that large pools of capital are approaching Bitcoin more defensively than they were a few weeks ago.

The Block described the $1.28 billion loss as the category’s worst week since late June. Its analysis also found that the latest exits pushed the group’s 2026 net flow back below zero.

None of this proves that Bitcoin is headed lower. ETF creations and redemptions can reverse quickly, and a single large product can distort the weekly picture in either direction.

The cleaner test is what happens next.

If IBIT’s withdrawals slow and demand returns across several funds, this week may look like a concentrated reset. If BlackRock keeps bleeding while the rest of the complex remains weak, the institutional demand problem will be harder to dismiss.

For now, the decisive fact is that $1.28 billion left Bitcoin ETFs.

It is that one enormous fund supplied nearly all of the exit pressure—and the rest of the market still could not absorb it.
