BlackRock’s iShares Bitcoin Trust (IBIT) posted a net outflow of $405.3 million on November 2, prompting social‑media speculation that the asset manager was selling Bitcoin (BTC). The outflow represents client redemptions, not a change in BlackRock’s own holdings.
Client redemptions drive the outflow
Spot Bitcoin exchange‑traded funds (ETFs) hold BTC directly. When investors redeem shares, the fund must deliver a proportional amount of Bitcoin to the market, reducing its asset base. The $405.3 million outflow therefore reflects investors withdrawing cash, which in turn forces the fund to sell the corresponding BTC.
Impact on IBIT and the broader ETF market
The outflow was the largest single‑day net withdrawal from IBIT since June 26, according to data from Farside Investors. It erased nearly a week’s worth of inflows, as the fund had attracted $410.6 million over four sessions from October 26 to October 29. Combined with a $233.7 million outflow on the preceding Friday, IBIT shed $639 million in two days.
Across all U.S. spot Bitcoin ETFs, total net flows were negative $398.6 million on the same day, with Fidelity’s FBTC being the only fund to record an inflow of $6.7 million.
Contextual factors
The withdrawals occurred after a major security breach at Binance, where $6.36 billion worth of crypto was stolen in what analysts described as the largest crypto hack on record. The incident, attributed to a North Korean hacking group, involved the loss of 18,270 BTC from a Binance hot wallet.
Additional market pressures included caution ahead of the U.S. midterm elections on November 3 and a broader sell‑off in technology stocks.
Long‑term perspective
Despite the recent outflows, IBIT’s cumulative net inflows since its launch in January 2024 total $65.9 billion, indicating a substantial overall inflow base. Ongoing redemption activity will be closely watched, as spot Bitcoin ETFs serve as a primary conduit for institutional sentiment toward BTC’s price.
