Bitcoin spot ETFs stayed in positive territory
According to SoSoValue, Bitcoin spot ETFs recorded a combined $154 million in net inflows between April 27 and May 1. The largest contribution came from BlackRock's IBIT, which brought in $136 million during the period, making it the main driver of the week's positive flow data.
The figures suggest that market demand for regulated Bitcoin investment products remained relatively resilient over the reporting window. While the source material does not provide a full breakdown for every fund, IBIT's dominant share of the inflows highlights the continued importance of large asset managers in shaping ETF flow trends.
Ethereum ETFs moved in the opposite direction
In contrast, Ethereum spot ETFs posted $82.47 million in net outflows over the same period. BlackRock's ETHA accounted for $71.44 million of that total, representing the bulk of the withdrawals. The divergence points to weaker short-term demand for Ethereum-based spot ETF products compared with Bitcoin.
With Bitcoin ETFs attracting fresh capital while Ethereum ETFs lost funds, the data reflects a clear split in investor positioning across major crypto asset classes during the week.
SOL spot ETF also posted a small outflow
Outside of BTC and ETH, SOL spot ETFs saw $1.24 million in net outflows. Although that amount was far smaller than the Ethereum figure, it still indicates mild fund withdrawals in the Solana-related ETF segment. Taken together, the weekly data shows a pattern of capital moving into Bitcoin products while flowing out of Ethereum and, to a lesser extent, SOL funds. ETF flow data is often watched as a proxy for institutional sentiment, though it should be evaluated alongside broader market conditions.
