According to Farside Investors data, US investors put close to $32 billion into US crypto exchange-traded funds in 2025 even as markets lost steam late in the year.
Blackrock Dominates FlowsBlackRock’s iShares Bitcoin Trust ETF, IBIT, accounted for most of the activity. Reports show IBIT took in about $24.7 billion. That makes its inflows roughly five times larger than the nearest rival, Fidelity’s FBTC.
Market watchers noted IBIT ranked near the top among all ETF flows, placing behind only a few broad index funds and a big treasury bond fund.
If IBIT’s number is removed, the wider spot Bitcoin ETF group actually finished the year with about $3 billion in combined outflows.
Ethereum Interest Strong But CoolingBased on reports, interest in Ethereum ETFs was real, but the momentum looks uneven. BlackRock’s iShares Ethereum Trust, ETHA, sits at nearly $12.6 billion in inflows. Fidelity’s FETH follows at $2.6 billion, while Grayscale’s Ethereum Mini Trust ETF holds about $1.5 billion.
Still, public on-chain data showed little renewed demand for spot Bitcoin and Ether ETFs in the last month of the year, suggesting flows may slow into 2026.
Spot Ether ETFs, which only became widely tradable after their July 2024 launch, gathered $9.6 billion in their first full year. Spot Solana ETFs, launched in late October, added $765 million through year end.
Altcoin ETFs Show Curiosity, Not FrenzyLitecoin and XRP ETFs also began trading in the latter half of the year, giving investors more choices for regulated altcoin exposure.
The sums are small compared with Bitcoin and Ether. Solana’s $765 million is an example of early interest that has not yet turned into a large, steady stream of assets. These products are being tested by the market.
Global Flows Tell A Different StoryRegulators and exchanges moved faster this year under new SEC leadership that was more open to approvals, which in turn helped institutional adoption in the US.
