BTC ETH ETFs draw $1.4B weekly inflows

TLDR

Spot Bitcoin (BTC) and Ethereum (ETH) ETFs just had their strongest week of inflows since January, with roughly $1.4 billion of new capital coming in.

1. Bitcoin and Ethereum ETFs took in about $1.4 billion combined last week, led by spot BTC funds with over $1.1 billion of inflows.
2. The rebound follows a weak Q1, as easing geopolitical risk and improving sentiment push money from cash-like vehicles back into risk assets, including crypto ETFs.
3. Sustained inflows could keep adding a structural bid for BTC and ETH, but flows remain sensitive to macro headlines and could reverse quickly.

Deep Dive

1. How Big The Inflows Were

CoinShares data, summarized in a recent market note, shows crypto ETFs pulled in about $1.4 billion over the past week, the largest weekly haul since January, with BTC and ETH funds dominating the flows. One report highlights that Bitcoin ETFs attracted around $1.12 billion, while Ethereum ETFs drew about $328 million in the same period, and both have now seen three consecutive weeks of net inflows.Crypto ETFs See Biggest Weekly Inflow Since January

Other trackers describe similar magnitudes. SoSoValue data cited in another piece places weekly spot BTC inflows at $996.38 million and ETH at $275.83 million, for a combined $1.27 billion, within rounding distance of the $1.4 billion headline.Crypto ETFs Haul $1.37 Billion

On the stock of assets, aggregate BTC ETF AUM is now about $102.86 billion and ETH ETF AUM about $14.19 billion, both up materially over the last week as tracked in ETF-asset metrics.

2. Why Flows Have Rebounded

The inflow burst follows a choppy first quarter where BTC and ETH ETF assets fell sharply from their mid?January peaks before stabilizing and then recovering.Crypto ETFs Haul $1.37 Billion

Macro and cross?asset flows are part of the story. Money market funds just saw a record weekly outflow of $172.2 billion, while equity, bond, gold and crypto funds all recorded net inflows, suggesting investors are rotating out of cash-like instruments into risk and alternative assets instead of de?risking entirely.Money market funds weekly outflow and crypto inflows

3. Implications And What To Watch

BTC ETF assets now account for roughly mid?single?digit percentages of Bitcoins market cap, and ETH ETFs for a smaller but growing slice, according to flow and AUM estimates in several ETF flow reports. Some analyses put BTC spot ETF assets at around 6 to 7 percent of BTCs market value, and ETH ETFs near 5 percent.Tokenpost ETF flow and market cap shares

Within the broader market, total crypto capitalization has risen only modestly over the past week, and BTC dominance has ticked up slightly, which fits a pattern where institutional flows first favor BTC and ETH before broader altcoin participation.

Going forward, key signals to monitor are:

1. whether BTC and ETH ETF inflows stay positive for multiple weeks,
2. how quickly ETF AUM grows relative to their underlying market caps, and
3. whether flows start to broaden or remain concentrated in a few low?fee, large issuers.

Conclusion

Bitcoin and Ethereum ETFs just logged their strongest weekly inflows since early in the year, signaling renewed institutional demand after a soft Q1. The combination of easing geopolitical risk, record outflows from money market funds, and still?growing ETF lineups has pulled fresh capital into regulated BTC and ETH products. The key question now is whether this is the start of a sustained inflow regime or a short-lived rotation that could reverse with the next macro or policy shock.
