U.S. spot Bitcoin ETFs experienced their highest daily inflow in more than four months on May 23, 2025, indicating a growing confidence from institutional investors as Bitcoin soared past $111,000. This surge in investment was led by the iShares Bitcoin Trust (IBIT) from BlackRock, which attracted $876.65 million, along with other ETFs like Fidelity’s FBTC and ARK 21Shares Bitcoin ETF (ARKB).
Over the past five trading days, U.S. spot Bitcoin ETFs have accumulated nearly $2.8 billion in inflows, coinciding with Bitcoin’s recent price rally that saw it reach a new all-time high of $111,888. This positive momentum reflects a shift in sentiment towards Bitcoin among institutional investors.
In contrast, Ethereum ETFs saw a much smaller net inflow of $12.3 million on May 22. The recent surge in ETF investments comes amidst various bullish developments in the crypto market, including JPMorgan Chase’s decision to offer clients access to Bitcoin and a wave of short liquidations that triggered a short squeeze, further boosting Bitcoin’s price.
While external events like the Cetus Protocol hack on the SUI blockchain have introduced some uncertainty in the market, the sustained inflows into Bitcoin ETFs show that institutional investors are increasingly seeing Bitcoin as a reliable store of value. As ETFs continue to accumulate Bitcoin, it could lead to a tightening of supply and potentially drive prices higher, solidifying Bitcoin’s position as a mainstream financial asset.
