United States spot Bitcoin exchange-traded funds (ETFs) have recorded their largest monthly outflow since the products began trading in January 2024. The development marked a significant shift in institutional sentiment toward the crypto market.
According to Galaxy Research, spot Bitcoin ETFs posted net outflows of $6.35 billion over the past 30 days, making it the worst 30-day period among 582 rolling windows tracked by the firm. The record outflow comes as Bitcoin faces a mix of market uncertainty, profit-taking, and shifting investor priorities.
Record Withdrawals Signal Institutional Caution
Recent data from Galaxy Research indicates that the pressure on Bitcoin ETFs has not resulted from a single day of selling but rather from a sustained trend of withdrawals. Before reaching the recent record outflow of $6.35 billion over 30 days, U.S. spot Bitcoin ETFs experienced 13 consecutive trading days of net outflows between May 15 and June 3.
During this period, investors withdrew approximately $4.33 billion, which is equivalent to more than 59,000 BTC, from these funds. Galaxy Research also highlighted that rolling outflow windows of 7, 10, and 20 days all reached record levels before setting the latest 30-day record.
This represents a significant shift from earlier this year when, in April, spot Bitcoin ETFs attracted about $1.97 billion in net inflows, demonstrating strong institutional confidence in the asset class. However, sentiment changed as bitcoin struggled to sustain upward momentum amid increasing uncertainty in broader financial markets.
Bitcoin Faces Growing Market Headwinds
The ongoing trend of ETF withdrawals is occurring at a challenging time for bitcoin. While the leading crypto is still well above the levels seen before the approval of spot ETFs, it has struggled to regain the momentum that previously pushed prices to record highs.
Galaxy Research noted that Bitcoin was trading near $64,000 when the latest outflow record was recorded. However, as of this report, its price has dropped to approximately $63,953, according to CoinGecko data. This indicates that investor caution has persisted, despite some relative price stability.
Despite these record outflows, Bitcoin ETFs rank among the most successful ETF launches in U.S. history, continuing to hold tens of billions of dollars in assets. Meanwhile, whether the trend continues or reverses will likely play a major role in shaping Bitcoin’s next market direction.
