U.S. spot Bitcoin ETFs recorded total net outflows of $649 million on May 18, according to SoSoValue, indicating a broad pullback in investor demand for listed Bitcoin funds. U.S. spot Ethereum ETFs also saw net outflows, losing $86.31 million on the same day and extending their run of withdrawals to six consecutive trading sessions. Spot crypto ETFs give investors regulated exchange-traded exposure to digital assets without directly holding the tokens, so sustained outflows are commonly watched as a signal of weakening near-term sentiment or portfolio rebalancing.
