Institutional Investors Flock to Crypto ETFs, Driving Bullish Momentum

The crypto community is abuzz with the recent bullish moves made by Bitcoin Exchange-Traded Funds (ETFs), which have seen massive inflows over the past month, according to a report from Bitwise CIO Matt Hougan.

Despite high price volatility in crypto markets, institutional demand continues to surge, with spot Bitcoin ETFs recording multiple consecutive days of inflows. The inflows in May alone surpassed an impressive $5.86 billion, signaling strong bullish sentiment among institutional investors.

Unusual Outflow on May 30, but Overall Impressive Gains

Data from Sosovalue shows Bitcoin ETFs experienced an unusual outflow of $616.22 million on May 30, breaking the month's impressive rally. However, the multiple streaks of significant inflows throughout May brought cumulative net inflows to $44.37 billion by month's end.

Despite the late-month outflow, Bitcoin ETFs still attracted $5.86 billion from institutional investors in May alone, demonstrating sustained confidence in crypto-backed financial products.

Ethereum ETFs Lag Behind, but Maintain Positive Momentum

• Ethereum ETFs maintained positive momentum with $564 million in net inflows
• Performance still trails Bitcoin ETFs by several billion dollars
• May marked the best-performing month for Ethereum ETFs in 2025 so far

This surge positions May as one of the top-performing months for both Bitcoin and Ethereum ETFs, reflecting growing institutional interest in cryptocurrency investment vehicles.
