Bitcoin ETFs Gain $1.59B in a Week as Ethereum Funds Face Outflows

• Bitcoin ETFs added over 25,000 BTC in a week, signaling strong institutional demand.
• Ethereum ETFs saw net outflows of 15,456 ETH, led by large withdrawals from ETHA and ETHE.
• Institutional investors favored Bitcoin ETFs over Ethereum, highlighting shifting capital allocation.

Bitcoin exchange-traded funds (ETFs) attracted large capital inflows this past week, with nearly all major products recording gains, according to blockchain analytics data tracked through April 23, 2025. Ethereum ETFs, by contrast, experienced widespread investor withdrawals, signaling a clear divergence in institutional demand for the top two digital assets.

On April 24 alone, the ten active Bitcoin ETFs collectively registered net inflows totaling 10,611 BTC, equivalent to approximately $983.85 million at current market valuations. The iShares Bitcoin Trust (IBIT), managed by BlackRock, contributed the largest portion of that daily figure, adding 6,886 BTC, worth an estimated $638.49 million. This brought IBIT’s total holdings to 582,664 BTC, valued at approximately $54.03 billion, cementing its lead among institutional-grade Bitcoin investment vehicles.

Weekly Data Shows Bitcoin ETF Net Inflows Surpass 25,000 BTC

In the broader context of the week ending April 23, Bitcoin ETFs saw cumulative net inflows of 25,431 BTC. Based on the average market price, these inflows were valued at around $1.59 billion and were spread across nearly all major funds.

Fidelity’s Wise Origin Bitcoin Fund (FBTC) reported a 7-day net inflow of 5,432 BTC, while ARK 21Shares Bitcoin ETF (ARKB) closely followed with 5,428 BTC. The newly launched Grayscale Bitcoin Mini Trust also showed activity, adding 641 BTC to its holdings.

Nine active Bitcoin ETFs posted net positive flows during the week, raising the total amount of BTC held across all listed U.S.-based ETFs to 1,185,964 BTC. The increase reflects sustained institutional engagement through regulated financial products.

Ethereum ETFs See Net Outflows Despite Minor Inflows in Select Funds

In contrast to Bitcoin, Ethereum-related ETFs struggled to attract new capital. Nine tracked funds recorded a combined net outflow of 15,456 ETH over the same seven-day period. The largest single outflow occurred in the iShares Ethereum Trust (ETHA), which lost 16,954 ETH during the week. This equates to approximately $29.69 million in capital removed from the fund.

The Grayscale Ethereum Trust (ETHE) also recorded significant investor withdrawals, with 21,826 ETH exiting the fund during the week. While smaller inflows were reported by Fidelity’s Ethereum fund (FETH), Bitwise’s ETHW, and VanEck’s ETHV, they were insufficient to offset the broader decline across the sector. As of April 23, total holdings across all Ethereum ETFs stood at 3,134,940 ETH, despite the recent outflows.

Institutional Allocation Strategies Show Divergence

The latest figures of ETF reveals disparity in how institutional investors are warming up to Bitcoin and Ethereum differently. This means that even as the buying pressure in Bitcoin ETFs persists signaling that there is demand for BTC through regulated products, Ethereum funds were experiencing outflows.

The data does not explain why investors behave this way, but the difference between these trends points to short-term Bitcoin trading among the participants in the ETF market. This kind of movement helps the tracking analysts categorize the ETF as the best tool to identify institutional positioning within the crypto space.
