BlackRock’s IBIT Drives Biggest Bitcoin‑ETF Inflow in Weeks

A single $665.2 million purchase shows concentrated ETF flows can force spot buying that alters market liquidity.

Overview

  • BlackRock’s iShares Bitcoin Trust took in $665.2 million on Monday, a single‑fund move that produced roughly $526.6–$526.7 million of net inflows for U.S. spot Bitcoin ETFs that day.
  • Other major Bitcoin funds lost cash on the same session, with Fidelity’s FBTC down about $83.6 million and Grayscale’s GBTC down about $54.9 million, highlighting a shift into one dominant product.
  • Spot ether ETFs continued a multi‑day redemption streak, posting $103.3 million of outflows on Monday while Solana spot products also recorded withdrawals.
  • Because spot ETFs hold the actual tokens, creations and redemptions require real market trades, so concentrated flows into or out of a few large funds can push prices and strain short‑term liquidity.
  • Since January 2024 the Bitcoin spot ETF complex has gathered tens of billions in net inflows and now holds roughly $105.46 billion in assets, a scale that makes single‑day concentration by flagship funds market‑moving.
