BlackRock Says Bitcoin Is Decoupling as IBIT Drives Large ETF Inflows

BlackRock says the shift could justify small institutional allocations by positioning Bitcoin as a low‑correlation portfolio diversifier.

Overview

  • BlackRock’s head of digital assets, Robert Mitchnick, said sentiment has turned noticeably and that Bitcoin is meaningfully decoupling from traditional equity markets following his televised interview on Monday.
  • U.S. spot Bitcoin ETFs posted about $853.5 million in net inflows for the week, with BlackRock’s iShares Bitcoin Trust (IBIT) capturing roughly $693.7 million, or about 80% of the total.
  • IBIT remains the largest U.S. spot Bitcoin ETF with roughly $48.5 billion in net assets, and ETF creation and redemption mechanics mean the dominant issuer and its trading partners can force large spot purchases or sales that amplify price moves.
  • Reported IBIT redemptions have been tiny—about 0.2% during volatility—suggesting sticky holders, but recent episodes such as the October 2025 flash crash and a late‑July two‑day inflow‑then‑outflow swing show concentrated flows can quickly widen losses or gains.
  • Analysts have noted a possible link between the recent Coldcard cold‑storage theft and stronger ETF demand, and the near‑term outlook depends on whether inflows remain concentrated in IBIT and how capital rotates between crypto and hot equity themes like AI.
