BlackRock's iShares Bitcoin Trust (IBIT) was the largest single contributor to the Bitcoin outflow. It accounted for approximately $234 million of the total.

CryptoBriefing 2026-10-31 05:46

What would settle it: BlackRock's own fund flow disclosure or Farside Investors' updated table showing IBIT's October 30 line.

What to make of it

Treat Fidelity's roughly $201 million FBTC outflow and the end of the four-day inflow streak as established; the overall size of the October 30 outflow and IBIT's role in it remain unsettled until Farside Investors or BlackRock publish a reconciled figure.
