Bitcoin Spot ETF Withdrawals Top $3.666 Billion—BlackRock, Fidelity, Grayscale Exit Surge

COINOTAG News, October 18 – the U.S. Bitcoin spot ETF market registered a reverse‑flow of assets, with a net outflow of $3.666 billion today. The bulk of the sell‑off came from leading providers: BlackRock IBIT shed $2.686 billion, while Fidelity FBTC dropped $67.4 million, Valkyrie BRRR withdrew $5.6 million, and Grayscale GBTC exited $25 million. Market analysts suggest the exodus reflects heightened volatility in the underlying Bitcoin price and a reassessment of risk exposure by institutional holders. Investors monitoring dollar‑close ETF flows should note the potential for a rebound as trading conditions normalize, but remain vigilant for further shifts in sentiment.
