Bloomberg analyst James Seyffart analyzed the fund flow trends of Bitcoin and Ethereum ETFs over the past year. Although crypto ETFs experienced a difficult period at the end of 2025, they still showed relative resilience and saw a significant rebound in funds at the beginning of 2026.
Bitcoin ETFs demonstrate strong resilience, with significant inflows on the first day of the year.
Although US Bitcoin spot ETFs saw outflows exceeding $6 billion between November and December 2025, drawing market attention, according to Bloomberg analyst James Seyffart, this outflow amount represents less than 10% of the peak inflows ($62 billion) in October of the same year. This indicates that most investors still choose to hold for the long term, and the year-end outflows are more likely for tax adjustments than a trend reversal, reflecting the market resilience of this asset class.
On the first day of 2026 (January 2nd), Bitcoin ETFs recorded inflows of $471 million, with BlackRock's IBIT alone receiving nearly $290 million. This was the largest net inflow in 35 trading days since November 11th, when 11 US ETFs saw a total inflow of $524 million in a single day.
Preliminary data from January 5 also showed continued capital inflows, indicating that investors are restarting their asset allocation plans as the new year begins.
Ethereum ETFs experienced high outflows due to the weakening price of ETH.
Compared to Bitcoin's stability, the liquidity of the US Ethereum spot ETF is relatively high, currently with an outflow rate of approximately 18%. Since reaching a peak of $15 billion in October 2025, it has seen a cumulative outflow of about $2.8 billion. Nevertheless, Seyffart believes that this outflow rate is still within a reasonable range when considered in relation to the price volatility of Ethereum (ETH) itself.
On the first day of 2026 (January 2nd), the Ethereum ETF recorded an inflow of $175 million, the largest single-day inflow in 15 trading days, with Grayscale's ETHE receiving the largest inflow. Although the data for January 5th is not fully released, it appears there has been a continuous influx of funds.
