Spot Bitcoin ETFs Record $208M Outflows on May 18 as ARKB Leads Withdrawals

According to ETF flow data from Bitbo and market trackers, U.S. spot Bitcoin exchange-traded funds posted $208.1 million in net outflows on May 18, with Bitcoin trading near $76,000 following a sharp multi-day correction. Ark 21Shares' ARKB recorded the largest single-day withdrawal at approximately $110.1 million, followed by Grayscale's GBTC with $43.5 million in redemptions and Fidelity's FBTC with $38.5 million in outflows.

The latest withdrawals extended a difficult week for digital asset ETFs, which experienced approximately $1 billion in cumulative outflows over the prior seven days, ending a six-week inflow streak. Bitcoin briefly fell below $76,700 during the session, marking its lowest level in roughly two weeks before stabilizing modestly higher.
