BlackRock's IBIT ETF recorded a $40.8 million net outflow on October 31, 2025, contributing to a total $291 million withdrawal from major Bitcoin and Ethereum ETFs. This significant outflow followed the release of U.S. inflation data, which heightened investor caution and uncertainty, leading to a broader impact on the cryptocurrency market. Ethereum's price fell by 4.5%, while Bitcoin also experienced notable declines, affecting other cryptocurrencies as well. The outflows also impacted major players such as Fidelity and ARK, although no official comments have been made by industry leaders. The market's reaction underscores the sensitivity of crypto assets to macroeconomic indicators like inflation, which continue to influence investor sentiment and market dynamics.
