Bitcoin ETFs have kicked off the week with remarkable momentum, recording $667 million in net inflows — the fourth consecutive day of gains. Industry giants BlackRock (IBIT), Fidelity (FBTC), and ARK 21Shares (ARKB) are fueling this surge, signaling renewed institutional confidence in digital assets.
Meanwhile, Ethereum ETFs are also quietly gaining traction, led exclusively by BlackRock’s ETHA, which brought in $13.66 million in net inflows without a single outflow reported across any Ether ETF.
Bitcoin ETF Momentum: What’s Fueling the Rally?
According to CoinDesk, the breakdown of Monday’s $667 million inflows is as follows:
- BlackRock’s IBIT: $305.92 million
- Fidelity’s FBTC: $188.08 million
- ARK 21Shares’ ARKB: $155.25 million
- Bitwise’s BITB: $16.02 million
- VanEck’s HODL: $7.44 million
- Invesco’s BTCO: Only ETF to report an outflow of $5.27 million
Cumulative Impact
- Total traded value: $3.63 billion
- Total net assets in Bitcoin ETFs: $124.97 billion
Larry Fink, CEO of BlackRock, recently remarked in a Bloomberg interview that “Bitcoin is emerging as a permanent asset class in diversified institutional portfolios.” This is echoed by the inflows into IBIT, which has consistently led the pack among spot Bitcoin ETFs since their historic approval by the SEC in January 2024.
Ethereum ETFs: A Quiet Rise
Though smaller in scope, Ethereum ETFs also showed positive signals. BlackRock’s ETHA ETF alone accounted for $13.66 million in inflows on Monday. No outflows were recorded across the nine Ether ETFs, suggesting that traders are cautiously optimistic about Ethereum’s position in the crypto ecosystem.
- Total volume traded: $468.73 million
- Net assets across ETH ETFs: $8.72 billion
According to James Butterfill, Head of Research at CoinShares, “Ethereum’s narrative as a foundational layer for DeFi and smart contracts continues to attract long-term investors, especially post-Dencun upgrade in March 2025.”
Institutional Appetite: A Return to Risk-On?
The surge in ETF inflows aligns with broader macroeconomic cues. With the Federal Reserve signaling a potential rate cut in June, risk assets like Bitcoin are becoming attractive again. As inflation eases and market uncertainty declines, institutions are rebalancing toward crypto exposure.
ARK Invest CEO Cathie Wood commented during a recent webcast:
“We believe Bitcoin has firmly established itself as a hedge against both inflation and monetary policy volatility. The flows we’re seeing now are just the beginning.“
What Comes Next?
With Bitcoin ETF net assets now nearing $125 billion and Ether ETFs stabilizing, the question is whether this trend will continue. Market watchers are keeping an eye on:
- SEC decisions on upcoming Ether spot ETFs beyond BlackRock
- Federal Reserve policy shifts and macroeconomic trends
- Bitcoin halving momentum and its lagging effect on price movement
Final Thoughts
The latest ETF flows confirm that institutional players are not just experimenting with crypto — they are doubling down. While retail sentiment remains cautiously optimistic, the scale and pace of inflows into products from BlackRock, Fidelity, and ARK Invest point to a deepening mainstream adoption of digital assets.
As crypto ETFs become a permanent fixture in traditional portfolios, the gap between Wall Street and the blockchain world continues to narrow.
