U.S. Spot Bitcoin ETFs Face $359 Million Outflow

Bitcoin ETF Net Flow Shift on May 29, 2025

U.S. spot Bitcoin ETFs witnessed a significant outflow of approximately $359 million on May 29, 2025, marking the end of a 10-day streak of inflows and the largest single-day exit since March.

The event highlights a drastic shift in institutional investor sentiment, impacting Bitcoin market dynamics and signaling potential increased short-term market volatility.

During the outflow event, Fidelity led with a -$166.3 million outflow, while Grayscale showed -$107.5 million and Ark 21Shares experienced -$89.2 million. Additionally, BlackRock’s IBIT recorded rare positive inflows of $125 million.

Institutional redemptions reversed a 10-day period that added $4.26 billion in net inflows. This led to reduced ETF cumulative inflows, decreasing from $45.34 billion to $44.99 billion. The lack of official statements from key ETF providers underscores the prevailing uncertainty.

The substantial net outflow underscores increased investor caution and is likely to amplify short-term Bitcoin price volatility. While no on-chain data was immediately available, these redemptions generally lead to BTC exiting custodial wallets.

Furthermore, these large reversals are reminiscent of past trends where substantial inflows are quickly followed by redemptions. This pattern of fluctuating investor confidence could exert additional pressure on BTC and adjacent markets.

Market participants interpret these results as signals of a potential shift in institutional outlook. Without regulatory input or further industry comments, the event highlights ongoing market sentiment vulnerabilities.

Farside Investors, “Bitcoin ETF net flows for May 29, 2025 recorded a significant outflow of $346.8 million, with major redemptions from FBTC (-$166.3M), GBTC (-$107.5M), and ARKB (-$89.2M), while IBIT was the only ETF with notable inflows (+$125.1M). This substantial net outflow signals increased investor caution and could exert downward pressure on Bitcoin price action in the short term, highlighting immediate market sentiment shifts.” Source
