U.S. spot crypto ETF flows diverged in the week ending May 15. U.S. spot Bitcoin ETFs recorded $1.039 billion in net outflows during May 11-15, while spot Ethereum ETFs saw $255 million in net outflows. Over the same period, XRP-related spot ETF flows posted $60 million in net inflows and Solana-related spot ETF flows added $58 million, indicating selective demand for alternative crypto exposure even as capital left the two largest cryptocurrencies. On May 15 alone, U.S. spot Bitcoin ETFs recorded $290 million in net outflows and U.S. spot Ethereum ETFs saw $65 million leave. The Bitcoin ETF pullback ended a six-week inflow streak; ARKB led weekly withdrawals with $324 million, followed by BlackRock’s IBIT at $317 million. Despite the reversal, total net assets for U.S. spot Bitcoin ETFs stood at $104.29 billion and cumulative net inflows reached $58.34 billion. The outflows were also linked to inflation concerns that weighed on risk appetite.
