Bitcoin ETF Flows Surge While Ethereum ETFs Struggle to Stay Afloat
BlackRock’s iShares Bitcoin Trust (IBIT) remains the leading Bitcoin exchange-traded fund (ETF), holding $48.73 billion in assets under management (AUM) as of March 19, 2025.
Despite a recent one-day outflow of $332.6 million on March 1 and weekly outflows of nearly $393 million, IBIT’s year-to-date inflows have exceeded $37 billion.

This proof of dominance is supported by a 3-month net flow of $4.23 billion and a 1-year net flow of $28.69 billion.
Bitcoin’s price climbing above $108,000 in December 2024 has supported IBIT’s position as a leading regulated investment option for crypto exposure.
Bitcoin Pulls Ahead as Ether Struggles to Keep Pace
On the other hand, Ether-based ETFs are struggling, with total AUM at $7.31 billion and a net outflow of $11.7 million being recorded on March 19, 2025.

Since their launch on July 23, 2024, these funds have struggled to attract capital, with cumulative inflows just exceeding $1 billion.
Industry giants like Grayscale’s ETHE, holding $3.46 billion in AUM, have seen outflows of $4,170.8 million since inception, while BlackRock’s ETHA manages $2.33 billion.
Even record-breaking inflow days, such as the $428.5 million recorded on Dec. 6, 2024, have been unable to reverse the overall decline, indicating diminishing investor interest in Ethereum-focused ETFs.
Market Dynamics Show Diverging Trends
As of March 20, 2025, the performance gap between BTC and ETH ETFs speaks to differing investor priorities. IBIT benefits from Bitcoin’s established market presence and BlackRock’s infrastructure, including Coinbase Prime technology for liquidity.Â

Ether ETFs, however, contend with higher fees—such as ETHE’s 2.5% expense ratio—and regulatory uncertainty surrounding Ethereum, limiting their appeal. Recent data shows IBIT with $1.59 billion in outflows over the past month, yet Ether funds’ smaller scale amplifies their $11.7 million daily loss.
Bitcoin’s store-of-value narrative resonates more than Ethereum’s global ecosystem, a trend that will continue unless regulatory or market factors improve Ether’s prospects.
