Bitcoin and Ethereum ETFs have seen a surge in investor interest, pulling in $1.1 billion in net inflows on January 6, 2025, following a slower start to the year. This marks a strong rebound after the funds had a shaky beginning in 2025, with Bitcoin ETFs seeing a $320 million dip. However, the latest data shows that Bitcoin and Ethereum ETFs have collectively attracted $1.75 billion in the first two trading days of January, according to CoinGlass data. This follows a successful year in 2024 when these ETFs garnered a total of $38 billion, providing easier access to the top cryptocurrencies through traditional brokerage accounts in the U.S.

Bitcoin ETFs alone accounted for $987 million of the total, with the biggest contributors being Fidelity’s FBTC, which pulled in $370.2 million, and BlackRock’s IBIT, which generated $209.1 million. Other funds such as ARKB from Ark Invest, Grayscale’s GBTC, and Bitwise’s BITB also contributed to the total influx. The two-day streak of positive inflows into Bitcoin ETFs follows a period of outflows in December 2024 and early January 2025.

On the Ethereum side, the ETFs saw $128.7 million in net inflows on Jan 6. BlackRock’s iShares Ethereum Trust (ETHA) led the charge with $124.1 million, pushing its assets to $4.11 billion. Fidelity’s Ethereum Fund (FETH) brought in $4.6 million. Ethereum ETFs have now accumulated $2.8 billion in net inflows since their launch in mid-2024.

As of now, U.S. spot Bitcoin ETFs hold $116.67 billion in assets, or 5.77% of Bitcoin’s market cap, while Ethereum ETFs hold $13.47 billion, or 3.01% of Ethereum’s market cap. Bitcoin ETFs have proven more popular, with the funds outpacing Bitcoin miner production in December 2024. Among the smaller Bitcoin ETFs, Grayscale’s Bitcoin Mini Trust and the VanEck Bitcoin ETF have also recorded significant inflows.
