Bitcoin and Ethereum ETFs See Single-Day Outflows on May 8 While Weekly Totals Stay Positive

Daily ETF flow data for May 8 shows net outflows from both Bitcoin and Ethereum products, even as the seven-day picture remains firmly positive. Bitcoin ETFs recorded a one-day net outflow of 2,022 BTC ($161.53M), while the weekly tally held at +18,496 BTC (+$1.48B). Ethereum ETFs saw a steeper single-day drain of 34,349 ETH ($78.35M), though the seven-day net remains constructive at +73,153 ETH (+$166.86M).

Solana ETFs bucked the daily trend, posting a one-day inflow of 76,912 SOL (+$6.85M) and a seven-day total of +368,912 SOL (+$32.83M) — a comparatively small dollar figure but consistent directional momentum for the youngest of the three ETF products.

The divergence between daily and weekly readings is the key context here: single-day outflows against a positive weekly baseline are a routine pattern in ETF flow data and do not, on their own, signal a structural shift in demand.
