US spot bitcoin ETFs posted net outflows of about $636 million, ending a three-day inflow streak, according to The Block and Cointelegraph. The Block reported BlackRock's IBIT led the withdrawals at $254.1 million, with four other funds also seeing redemptions. Cointelegraph put the October net outflow at $175 million.

Evidence strength Multiple publishers

2 independent publishers report it (copies of the same text count once); they may still rely on one underlying source. An official source would raise it.

Claims and open questions

What sources claim

  • The Block reported that BlackRock's IBIT led Thursday's net outflows with $254.1 million, while four other funds also saw withdrawals.
  • Cointelegraph reported that Thursday's withdrawals ended a three-day inflow streak and left US spot bitcoin ETFs with $175 million in net outflows for October.
  • The Block reported the day's total net outflows at about $636 million, erasing the previous day's inflows.

Still unresolved

  • Whether the outflow figures reflect a single trading day's final tallies or preliminary data that issuers or fund trackers may revise.
  • What share of the redemptions came from a single large holder versus broad-based selling across IBIT and the other four funds.
