Investors in BlackRock's iShares Bitcoin Trust (IBIT) pulled roughly $403 million worth of Bitcoin out of the fund in a single day, extending a five-session outflow streak that has now surpassed $1 billion in cumulative withdrawals.

Fund flow data for November 2, 2026 put IBIT's net outflow at $405.3 million, the largest one-day redemption for the fund since June 26. Estimates of the client-driven selling range between $403 million and $405 million, with the precise figure depending on which tally is used.

Redemption mechanics, not a BlackRock decision

Understanding the move requires separating BlackRock's role from that of its clients. The asset manager itself did not decide to sell Bitcoin. Its clients redeemed their ETF shares, and the fund was required to release the corresponding amount of Bitcoin to settle those positions.

The released coins were sent predominantly to Coinbase Prime, the institutional brokerage arm of Coinbase, where they were sold. The Bitcoin therefore did end up hitting the open market — but as a consequence of investor decisions, not a directive from BlackRock's trading desk. In that sense, the episode reflects client behavior rather than any strategic move by the issuer.

One fund drove nearly all of the sector's outflows

Across the full lineup of US spot Bitcoin ETFs, net outflows came to roughly $398.6 million on the day. Fidelity's Wise Origin Bitcoin Fund (FBTC) bucked the trend, recording a modest inflow of $6.7 million.

IBIT's $405.3 million in outflows, offset by FBTC's $6.7 million in inflows, adds up almost exactly to the sector-wide total. In effect, BlackRock's fund accounted for essentially all of the day's net selling pressure among US spot Bitcoin ETFs, underscoring how concentrated the session's flows were.

A streak, not a one-off

The November 2 redemption was not an isolated event. It came as part of a longer run of withdrawals that stretched into early November, a period that coincided with a selloff in technology stocks led by the Nasdaq.

Bitcoin itself, meanwhile, has been confined to a relatively tight trading band over the same period, holding between $76,000 and $80,000. Because these flows are tallied and published daily, the sessions ahead will show plainly whether the streak extends further or comes to an end.

Still the largest fund in its category

For all of the recent outflows, IBIT remains the biggest US spot Bitcoin ETF, leading the category both by assets under management and by cumulative net inflows since its launch.

What it means for Bitcoin and ETF investors

The most direct effect concerns supply. Every redemption that ends with coins being sold through Coinbase Prime adds Bitcoin to the market, illustrating how ETF redemptions translate into spot-market selling through the fund's settlement process. With cumulative IBIT redemptions topping $1 billion in just five sessions, that extra supply could weigh on prices if demand from other buyers does not keep pace.

The heavy concentration of selling in a single fund — while Fidelity's FBTC managed a small inflow — may point to investors reshuffling which products they hold, or to a particular set of IBIT holders deciding to step back from that specific fund, rather than signaling a uniform exit from the asset class as a whole. The next several daily flow reports will be worth reading for two things in particular: whether IBIT's redemptions continue, and whether offsetting inflows elsewhere in the category keep absorbing part of the pressure.

June 26 stands as the key comparison point: the last time IBIT clients redeemed at anything close to this scale in a single session.
