Crypto ETF Flows Diverge: SOL and XRP Post Inflows as BTC and ETH Face Significant Outflows on May 18

On May 18, the cryptocurrency exchange-traded fund (ETF) market exhibited divergent performance across major digital assets. According to market data, spot Bitcoin (BTC) and Ethereum (ETH) ETFs experienced significant selling pressure, recording net outflows of $648.64 million and $86.31 million, respectively. In contrast, alternative asset products showed resilience; spot Solana (SOL) ETFs posted net inflows of $2.06 million, while spot Ripple (XRP) ETFs saw a modest gain of $750,440. This shift suggests a temporary cooling period for the two largest cryptocurrencies by market capitalization, even as investor interest in specific altcoin-based spot products remains positive. The data highlights a complex day for institutional crypto investment vehicles, characterized by heavy exits from primary assets and selective entries into secondary ones.
