Ether ETFs in 2025 experienced significant volatility, marked by rapid growth and sharp drawdowns. The year began with substantial inflows and outflows, transitioning into a summer accumulation phase where weekly inflows peaked at $2.85 billion. However, from September to November, the market saw heavy outflows, reducing net assets from $22 billion to under $17 billion. Despite the asset decline, high trading volumes indicate active management rather than investor retreat. Looking ahead, future fund flows may depend on Ethereum's network growth, staking economics, and investor sentiment as measured by the fear and greed index.
