Overview
- US spot Bitcoin ETFs recorded about $2.4 billion in net inflows for the week ending Sept. 25, with BlackRock’s IBIT taking roughly $1.2 billion and lifting its assets to near $67 billion.
- On‑chain data shows centralized exchanges shed roughly 31,700–35,800 BTC the same week as ETF buys placed coins into custody, removing a significant portion of the freely tradable supply.
- Fund flows have been episodic and front‑loaded, with one large Monday inflow that then tapered through the week and combined US spot crypto ETF flows dropping about 80% to roughly $65 million on Sept. 28–29.
- Institutional demand is broadening beyond Bitcoin into Ether, Solana and XRP ETFs, with Solana products offering staking passthrough for yield and XRP demand rising after the SEC‑Ripple legal clarity.
- Since launch, US spot Bitcoin ETFs have taken in about $57.6 billion and now hold nearly $108 billion in assets, a scale that can amplify short‑term price moves and reshape liquidity dynamics in crypto markets.
