BlackRock Drives Monday’s Large Bitcoin ETF Inflow

A single $665.2 million IBIT subscription left bitcoin near $81k while rebuilt futures leverage plus heavy put buying raise the chance of forced selling before the Fed meeting.

Overview

  • BlackRock’s iShares Bitcoin Trust took in $665.2 million on Monday, which more than offset withdrawals from rivals and produced a $526.6 million net inflow for U.S. spot bitcoin ETFs.
  • Fidelity’s FBTC and Grayscale’s GBTC recorded sizable outflows that made the day’s positive total heavily concentrated in one product rather than broad buying across funds.
  • Bitcoin’s price stayed weak near $81,000–$82,000 despite the ETF inflows, showing the purchases were absorbed by selling pressure and exchange order books.
  • Derivatives data show rebuilt leveraged exposure and a bearish options skew, with futures open interest rising and puts outtrading calls while the Oct. 30 $80,000 put was notably active.
  • Analysts warn that a break below roughly $79,800 would likely trigger forced selling into an accumulation band near $77,600–$80,400, and the Fed meeting and inflation data are key near‑term catalysts to watch.
