Bitcoin (BTC) Spot ETFs Record Their Highest Daily Inflow in Over Four Months

On May 23, 2025, U.S. spot Bitcoin ETFs recorded their highest daily inflow in over four months, reflecting growing institutional confidence as Bitcoin continues its upward trajectory past $111,000.

May 22 saw U.S. spot Bitcoin exchange-traded funds (ETFs) receive a combined net inflow of $934.21 million, the largest daily total in more than four months, as the cryptocurrency rose past $111,000, largely driven by a major bank offering clients access to BTC.

According to data from Farside Investors, the bulk of the ETF money went to iShares Bitcoin Trust (IBIT) with $876.65 million in net flows. Meanwhile, Fidelity’s FBTC saw $48.66 million enter the product.

Among other ETFs, ARKB, by ARK and 21Shares, had a modest $8.90 million flowing in, while Bitwise’s BITB saw no net flows for the day.

The measure is part of a broader trend, with the U.S. spot Bitcoin ETFs having seen nearly $2.8 billion in inflows over the past five trading days. The momentum aligns with Bitcoin’s recent price rally, which saw the cryptocurrency hit a new all-time high of $111,888 on Thursday, up 7.3% from a low of $104,200 the previous day.

The crypto market rose 2.5%, putting its capitalization at $3.48 trillion—its highest since February.

This strong performance follows a period of turbulence in the crypto derivatives market, which saw a wave of short liquidations, amounting to $265 million across the crypto market—including $45.2 million in short BTC positions—trigger a powerful short squeeze, largely driving Bitcoin’s price up.

However, the market remains sensitive to external factors. The Cetus Protocol hack on the SUI blockchain, resulting in losses exceeding $223 million, has brought some turbulence, especially for tokens linked to the SUI ecosystem.

Although this event did not directly impact Bitcoin’s price, it serves as a reminder of the broader risks in the decentralized finance (DeFi) domain, which could influence investor behavior in the coming days. Despite this, the sustained inflows into Bitcoin ETFs suggest that institutional investors are increasingly viewing Bitcoin as a reliable store of value, even amidst such challenges.

Looking ahead, the continued accumulation by ETFs could further tighten Bitcoin’s supply, potentially pushing prices higher. U.S. spot Bitcoin ETFs now hold over 1.2 million BTC, 6.35% of the total supply.

If this trend persists, Bitcoin’s role as a mainstream financial asset may become even more pronounced, especially as more traditional institutions decide to join the crypto sphere.
