- Bitcoin ETFs in the U.S. saw a record $25 billion in trading volume last week.
- Net inflows hit $2.75 billion, the second-highest since launch in early 2024.
- BlackRock’s IBIT now holds over 3.3% of the global Bitcoin supply.
The week ending May 24 marked the highest trading activity for U.S. spot bitcoin ETFs in 2025. These funds saw $25 billion in turnover, setting a new weekly record. The sharp rise in activity followed Bitcoin’s climb to an all-time high of nearly $109,000.
Investor appetite drove $2.75 billion in net inflows over the span. That was the second-largest week in inflows since spot bitcoin ETFs launched at the start of 2024. Trading volume also exceeded December 2024 levels, a sign of fresh vigor in the market.
Bitcoin declined slightly by Friday, yet this didn’t hinder the pace of inflows. The investors continued to actively participate with funds, reflecting increased faith in authorized cryptocurrency investment products.
BlackRock’s Bitcoin ETF Gains Institutional Traction
BlackRock’s IBIT fund had a 30-day streak without any outflows. One day reported net-zero while rest had ongoing buying. IBIT now holds close to 3.3% of the supply. Its net asset value exceeded $71 billion.
That sum is more than three times Fidelity’s FBTC, which is the second-largest spot bitcoin ETF. Its consistent inflows are reflective of strong institutional, as well as retail investor demand. The size and consistency of this fund are creating new benchmarks in ETFs.
Its popularity confirms how major asset managers are turning into core participants in exposure to Bitcoin. This trend continues to move crypto into mainstream investment portfolios.
Ethereum ETFs Gain Despite Lower Volume
Ethereum-focused ETFs also experienced significant movement. The net inflows came close to $250 million for the week. That level was highest since the beginning of February, even though trading quantity was slightly less. The inflows indicate improving investor appetite for Ethereum.
Now, capital is starting to flow into ETH products after months of inaction. The new demand comes in response to Bitcoin’s robust performance and may be a case of trend following from Ethereum. Action remains lagging behind BTC funds, but increasing flow signals increasing vigor.
