Spot Bitcoin ETFs traded in the US reached a new record of $40.3 billion in lifetime flows as of May 8, 2025, a milestone reflecting renewed investor confidence and surging institutional interest. BlackRock’s iShares Bitcoin Trust (IBIT) dominated the landscape, capturing nearly 92% of net inflows during the latest surge.
This new high aligns with Bitcoin’s (BTC) recovery above $100,000, following a dip to its year-to-date low in early April. Data shows that between April 7 and May 8, net flows into spot BTC ETFs increased by almost $4.8 billion. IBIT alone accounted for $4.4 billion of those flows, far outpacing competitors like Fidelity’s FBTC.
Industry analysts, including Bloomberg’s Eric Balchunas, highlighted the significance of robust ETF flows in reflecting real investor sentiment. The record-setting inflows, achieved soon after recent market turbulence, signal resilient confidence in digital assets, particularly among institutional investors. Spot Bitcoin ETFs are becoming increasingly important as channels for traditional finance to allocate to cryptocurrencies, reinforcing Bitcoin’s role as a mainstream portfolio asset.
Analysts expect further inflows to spot Bitcoin ETFs, driven by favorable historical trends and anticipated regulatory developments, cementing Bitcoin’s presence within the broader financial ecosystem.
