Bitcoin ETFs Break Records in May, But End the Month with a Shocking Outflow

Bitcoin ETFs Break Records in May: But Can the Momentum Last?

According to a recent post by Bitwise CIO Matt Hougan, the cryptocurrency world is once again in awe of the bullish move made by Bitcoin ETFs, which follows significant inflows over the past month. Spot Bitcoin ETFs saw inflows for several days in a row, indicating that institutional demand has continued to rise despite the extreme price volatility over the previous month. The total amount of money invested in Bitcoin ETFs in May exceeded $5.86 billion. This extraordinary increase suggests that institutional investors are feeling bullish.

Surge Then Slump: Bitcoin ETFs End May With $616M Pullback

The huge gain that Bitcoin ETFs saw throughout May didn’t last until the end of the month, per data from Sosovalue. On May 30, there was an outflow that was unusual for the ecosystem.

According to the data, on May 30, Bitcoin ETFs reported a net outflow of $616.22 million. However, as of May 30, the ETFs’ cumulative total net inflows reached an incredible $44.37 billion due to many streaks of high inflows during the month. Bitcoin ETFs attracted $5.86 billion from institutional investors in May alone, despite the significant withdrawal on May 30.

May Becomes 2025’s Best Month Yet for Ethereum ETFs with $564M in Inflows

According to the Sosovalue graphic, BTC ETFs have a whopping $5.23 billion in monthly net inflows in May, over twice as much as the $2.97 billion in April. Remarkably, the $4.6 billion in outflows that occurred in February and March have been balanced by this inflow, thereby recouping losses from both months.

With a net inflow of $564 million, Ethereum ETFs have also maintained a positive pace, but they are still several billion dollars behind their Bitcoin equivalents. This large net inflow makes May the best-performing month for Ethereum ETFs in 2025 thus far, notwithstanding a few noteworthy outflows during the month. This significant increase places May among the best-performing months for Ethereum and Bitcoin ETFs, indicating heightened institutional trust and interest in financial instruments backed by cryptocurrencies.
