BlackRock's IBIT Bleeds $403M in a Day as Outflow Streak Tops $1B

Investors in BlackRock's iShares Bitcoin Trust (IBIT) pulled roughly $403 million worth of Bitcoin out of the fund in a single day on November 2, 2026, according to fund flow data. The precise tally depends on the provider: estimates of client-driven selling land between $403 million and $405 million, with fund flow trackers recording a net outflow of $405.3 million.

That figure marks the largest one-day redemption for IBIT since June 26 of this year. It also extended a five-session outflow streak in which cumulative withdrawals from the fund exceeded $1 billion — meaning IBIT clients liquidated on the order of $200 million per session over that stretch.

Who actually sold the Bitcoin?

The mechanics matter here. BlackRock did not decide to dump Bitcoin. Its clients redeemed their ETF shares, and the fund had to release the matching amount of Bitcoin to settle those positions.

Those released coins mostly went to Coinbase Prime, the institutional brokerage arm of Coinbase, where they were sold. So the Bitcoin did end up hitting the market — but it arrived there because of investor decisions, not a call from BlackRock's trading desk.

This distinction carries operational weight for practitioners. An ETF redemption is a client-initiated unwind, and the fund's authorized participants handle settlement through the custody chain, in this case ending at Coinbase Prime. The market impact is real, but the seller of record is the redeeming investor cohort, not the asset manager.

How much of the market's selling was IBIT?

Essentially all of it. Across the full lineup of US spot Bitcoin ETFs, net outflows came to about $398.6 million on November 2.

One fund bucked the trend. Fidelity's Wise Origin Bitcoin Fund (FBTC) recorded a modest inflow of $6.7 million. IBIT's $405.3 million in outflows, offset by FBTC's $6.7 million in inflows, lands almost exactly on the sector-wide total — meaning BlackRock's fund accounted for essentially the entire day's net selling pressure among US spot Bitcoin ETFs.

Is this a one-off or a pattern?

It is a streak, not an isolated bad afternoon. The November 2 redemption extended IBIT's five-session outflow run, with cumulative withdrawals over that stretch exceeding $1 billion.

The streak ran into early November alongside a selloff in tech stocks led by the Nasdaq. Bitcoin itself has traded in a fairly tight band between $76,000 and $80,000.

For all the red ink, IBIT remains the largest US spot Bitcoin ETF. It leads the category both by assets under management and by total historical net inflows.

What does this change for holders?

The most direct effect is on supply. Every redemption that ends with coins being sold through Coinbase Prime adds Bitcoin to the open market. With cumulative IBIT redemptions topping $1 billion in just five sessions, that additional supply could weigh on prices if demand from other buyers does not keep pace.

The concentration of selling in one fund, while Fidelity's FBTC managed a small inflow, suggests investors may be reshuffling which products they hold — or a particular set of IBIT holders deciding to step back — rather than a uniform exit from the asset class.

The comparison point to keep in mind is June 26, the last time IBIT saw a single-day redemption this large. Whether the current streak extends past that precedent's aftermath, or reverses as it did over the summer, will be the number institutional desks watch when the next flow print lands.
