On October 10th, 2025, Ethereum spot ETFs experienced a notable outflow of $175 million across nine funds. This marks a reversal after eight consecutive days of inflows totaling nearly $2 billion, reflecting changing investor behavior and impacting the market dynamics for Ethereum. BlackRock led outflows with a substantial withdrawal of $80.19 million, followed by Grayscale with $30.57 million. The sudden outflow coincided with a dip in Ethereum’s price to around $4,300, potentially hitting technical support levels. Meanwhile, Bitcoin spot ETFs saw inflows totaling nearly $198 million, suggesting capital shifting from ETH to BTC, as seen in the robust trading volume of $40.4 billion and an increase in ETH futures trading by 21.5%. Analysts anticipate a normal rotation cycle following past accumulation streaks of both assets. The evolving landscape for ETFs requires close monitoring and adaptation from financial institutions like BlackRock. While regulatory changes and technological advancements remain key drivers, historical trends suggest continued shifts between Ethereum and Bitcoin as the underlying technologies continue to evolve.
