- BlackRock’s iShares Bitcoin Trust leads US ETF inflows.
- IBIT outperformed Vanguard’s VOO in daily flows.
- Bitcoin reached a new all-time high of $110,000.

BlackRock’s iShares Bitcoin Trust (IBIT) led all US-based ETFs in inflows following Bitcoin’s rally to a record high in May 2025.
BlackRock’s IBIT dominance in ETF inflows underscores the growing institutional interest in cryptocurrency investments amid Bitcoin’s price surge.
BlackRock’s iShares Bitcoin Trust (IBIT) recently recorded significant inflows, achieving a single-day inflow of $877.18 million. Bitcoin’s upward trend bolstered IBIT’s performance, propelling it to outshine established market players.
The ETF market witnessed strong movement with IBIT accumulating $8 billion over five weeks. This trend reflects an increased institutional interest in Bitcoin investments. Eric Balchunas, a Bloomberg ETF Analyst, confirmed IBIT’s dominance over traditional heavyweights:
“IBIT attracted $877.18 million in inflows that day, outpacing traditional heavyweights like Vanguard’s VOO, which tracks the S&P 500.”
Bitcoin ETFs have seen heightened trading volumes, indicating sustained investor interest. Traditional ETFs like Vanguard’s VOO received relatively lower inflows, highlighting the shift toward crypto investments.
Bitcoin’s ascent to over $110,000 has mirrored a broader trend towards cryptocurrency and away from traditional assets like gold. Regulatory frameworks continue to evolve, impacting institutional adoption.
The surge in IBIT inflows suggests potential long-term shifts in investor sentiment. Data indicate a movement from safe-haven assets to digital currencies, hinting at prolonged momentum for Bitcoin as an asset class.
