A tidal wave of investment has surged into U.S. spot Bitcoin ETFs, with a staggering $2.75 billion flowing in during the week ending May 23, 2025.
This marks a dramatic 4.5-fold increase compared to the previous week’s more modest $608 million inflow, signaling renewed institutional appetite for digital asset exposure.
The recent performance caps an impressive five-week streak of positive inflows, helping erase the $7 billion outflow dip experienced during the February-March correction period.
Bitcoin ETFs post five consecutive weeks of positive inflows, rebounding from earlier $7 billion correction-driven outflows.
Year-to-date inflows have now reached approximately $7.5 billion, surpassing February’s previous peak of $7.2 billion.
BlackRock’s iShares Bitcoin Trust (IBIT) has dominated the competition like a crypto Goliath among Davids.
With net assets exceeding $71 billion, IBIT now holds roughly 3.3% of all circulating Bitcoin—more than triple the holdings of its nearest competitor, Fidelity’s FBTC.
These trends showcase the impressive growth of the crypto ETF space, which has expanded to include 304 products globally with offerings across 65 different providers.
However, even giants stumble occasionally.
IBIT recently ended its impressive 31-day inflow streak with a record $430.8 million outflow on May 30.
Trading activity has reached fever pitch alongside these inflows.
The same week witnessed $25 billion in spot Bitcoin ETF trading volume—the largest weekly exchange in 2025—coinciding with Bitcoin smashing through the $108,000 barrier to establish new all-time highs.
Ethereum ETFs have also enjoyed the rising tide, attracting $250 million in their strongest showing since February.
The broader crypto ETF market led April’s thematic ETF surge with a $3.7 billion asset increase, bringing total thematic ETF assets to $317.4 billion—just shy of January’s record.
Geographically, the investment enthusiasm remains primarily American, with U.S. funds contributing the lion’s share of inflows.
Germany and Hong Kong followed with notable positive contributions, while Sweden, Canada, and Brazil registered the largest outflows, swimming against the global current.
Despite occasional volatility spikes during outflow days, the overall trend remains decisively positive, with ETF inflows helping maintain Bitcoin’s price stability above key resistance levels.
The transparent daily holdings reporting of these Bitcoin ETFs has contributed significantly to investor confidence in the digital asset market.
The total net asset value of these funds reached an all-time high on Thursday before experiencing a slight decline on Friday as Bitcoin’s price stabilized around $108,900.
