US Bitcoin Spot ETFs suffered substantial investor withdrawals last week, with net outflows totaling $1.26 billion. This marks the largest net loss in three months and highlights ongoing pressure on the Bitcoin ETF market amid falling cryptocurrency prices.

Monday accounted for the most significant daily outflow, with investors pulling nearly $649 million—the highest single-day withdrawal since late January. Subsequent days continued this trend with consistent, though smaller, daily net outflows, resulting in six consecutive days of negative fund flows. Overall, 80% of the past ten trading days saw net redemptions from Bitcoin Spot ETFs.

Among individual funds, BlackRock’s Bitcoin Trust (IBIT) experienced the largest net withdrawals, with investor outflows surpassing inflows by $1.01 billion. Despite this, IBIT remains the dominant player, managing net assets worth over $61 billion—roughly six times larger than its closest rival. Other major Bitcoin ETFs like Fidelity’s FBTC and Ark/21Shares’ ARKB also faced notable outflows of around $111 million and $107 million, respectively.

Smaller Bitcoin ETFs including Bitwise BITB, VanEck HODL, Valkyrie BRRR, Invesco BTCO, and Franklin Templeton EZBC recorded outflows ranging between $3 million and $10 million. Morgan Stanley’s MSBT, a recent market entrant, was the only fund to post net inflows last week, attracting around $1.11 million from investors. Several funds such as Grayscale’s GBTC and BTC trusts, Hashdex DEFI, and Bitwise BTCW showed no net activity during this period.

Year-to-date, Bitcoin Spot ETFs have now recorded cumulative net outflows approaching $1 billion in May, though total inflows since launch remain high at over $57 billion. The market currently holds nearly $99 billion in net assets.

Ethereum Spot ETFs have faced similar selling pressure, logging $215 million in net withdrawals last week alone. This continues a 10-day streak of daily net outflows totaling $471 million. Ethereum ETFs’ total cumulative inflows stand at $11.6 billion, with net assets valued at $11.8 billion, representing approximately 4.7% of Ethereum’s market capitalization.

At the time of reporting, Bitcoin traded near $76,700 while Ethereum held around $2,100, both showing modest daily gains despite fund outflows.
