Shock of Ethereum Spot ETF's record outflows at the end of the year

On December 31, 2025, the digital asset market witnessed a remarkable phenomenon. A total net outflow of $72,058,600 was recorded from multiple Ethereum spot ETFs on that day alone. According to data platform SoSoValue, none of the nine Ethereum spot ETFs recorded net inflows on this day, highlighting the overall cautious stance of the market.

Grayscale-led outflows accelerate, posting a deficit of over $30 million

Leading the outflows is the Grayscale Ethereum Mini Trust ETF (ticker: ETH). This ETF recorded the largest daily net outflow of $31,983,800, becoming the focus of market attention. Nevertheless, the fund’s total net inflow over time still reaches $1.488 billion, demonstrating solid performance throughout the year.

BlackRock-related funds also experience capital outflows, increasing pressure on the overall market

The second-largest outflow occurred from the BlackRock ETF (ticker: ETHA). This ETF posted a net outflow of $21,508,200 in one day, following Grayscale’s outflows. This approximately $28 million outflow reflects year-end portfolio adjustments by institutional investors. However, ETHA’s total cumulative net inflow still amounts to $12.56 billion, maintaining its position as a major player in the market.

Overall ETF market sees over $12.3 billion in cumulative inflows, indicating market maturity

As of the time of writing, the total net assets of the Ethereum spot ETF market have reached $17.94 billion. The ETF market capitalization accounts for 5% of Ethereum’s total market cap, leaving room for further growth. Notably, the cumulative net inflow has reached $12.328 billion, a key indicator that institutional interest in Ethereum continues to grow. Despite the temporary outflows at year-end, the long-term trend indicates ongoing market maturation and expansion of the ETF sector.
