U.S.-listed spot bitcoin ETFs posted their biggest single-day inflow of 2025, attracting $1.2 billion as bitcoin climbed to a new all-time high. The surge in ETF demand came alongside strong momentum in spot crypto markets and was reinforced by another solid session for ether ETFs, which brought in $383.10 million. Together, bitcoin and ether ETF products absorbed nearly $1.6 billion in one day, highlighting the strength of institutional participation in regulated crypto investment vehicles.
Bitcoin ETFs Set a New 2025 Daily Inflow Record
The largest share of bitcoin ETF inflows went to BlackRock’s IBIT, which drew $448.49 million. Fidelity’s FBTC followed with $324.34 million, while Ark 21Shares’ ARKB added $268.70 million. Other funds that contributed to the strong day included Grayscale’s Bitcoin Mini Trust with $81.87 million, Bitwise’s BITB with $77.15 million, VanEck’s HODL with $15.24 million, and Valkyrie’s BRRR with $3.21 million.
Only one bitcoin fund reported net outflows on the day: Grayscale’s GBTC, which saw $40.17 million leave the product. Even so, that outflow was small relative to the scale of inflows across the broader ETF complex. Market activity was also robust, with total bitcoin ETF trading volume reaching $6.31 billion. Net assets across bitcoin ETFs climbed to a record $143.86 billion, and the segment now represents 6.37% of bitcoin’s total market capitalization.
Ether ETFs Extend Their Positive Streak
The rally in crypto ETF demand was not limited to bitcoin. Spot ether ETFs continued their own streak of positive net flows, bringing in $383.10 million for the day. BlackRock’s ETHA led the group with $300.93 million in inflows, indicating that investor appetite remains concentrated in the largest and most liquid products. Fidelity’s FETH added $37.28 million, while Grayscale’s Ether Mini Trust and ETHE recorded $20.70 million and $18.89 million, respectively.
Smaller but still positive contributions came from Bitwise’s ETHW, which attracted $3.23 million, and VanEck’s ETHV, which added $2.06 million. Total trading volume across ether ETFs reached $1.23 billion, and net assets increased to $12.50 billion. The continued accumulation suggests that institutional interest is broadening beyond bitcoin and extending into ether exposure through regulated exchange-traded products.
Institutional Demand Remains the Key Market Driver
The latest flow data points to a market environment where price momentum and ETF demand are reinforcing each other. Bitcoin’s rise to a fresh all-time high coincided with the strongest single-day bitcoin ETF inflow of the year, a combination that is likely to keep attention focused on the role of institutional capital in the current cycle. The figures also show that ETF demand is not purely a headline phenomenon: it is visible in inflows, in trading activity, and in the steady expansion of assets under management.
For bitcoin, the milestone is especially significant because ETF assets now account for a meaningful share of the asset’s total market capitalization. That level of penetration signals the growing importance of U.S.-listed spot ETFs as a channel for capital formation and price exposure. For ether, the continued inflow streak suggests that investors are becoming increasingly comfortable using ETF structures to gain access to major crypto assets beyond bitcoin.
While one-day data does not by itself define a long-term trend, the scale of the latest inflows stands out. The fact that seven bitcoin ETFs posted gains on the same day, with only GBTC seeing net redemptions, reflects the breadth of demand across issuers. Similarly, the concentration of ether inflows in leading products such as ETHA and FETH points to a market where investors continue to prefer large, recognizable fund brands when building crypto exposure.
Overall, the latest session marks a notable moment for the U.S. crypto ETF market. Bitcoin ETFs shattered their prior 2025 daily inflow record at the same time BTC made a new price high, while ether ETFs maintained strong positive momentum. With assets, volumes, and net subscriptions all climbing together, the data suggests that institutional demand for listed crypto products remains firm and shows few signs of slowing.
