Spot Bitcoin ETFs recorded a single-day net outflow of 3,361 BTC ($256.91M) on May 18, with the seven-day cumulative drain reaching 12,478 BTC ($957.71M) — a sustained withdrawal pace that signals institutional repositioning rather than a one-off redemption spike.
Ethereum ETFs fared no better: 26,151 ETH ($55.23M) left on the day, and the weekly tally stands at 113,035 ETH ($238.73M) in net outflows. Together, BTC and ETH vehicles have shed close to $1.2 billion in a single week, a meaningful headwind for spot price support.
The lone bright spot is Solana. SOL ETFs pulled in 3,425 SOL ($288K) on the day and 605,484 SOL ($50.86M) over the past seven days — a divergence that suggests early-stage institutional appetite for SOL exposure is still building even as the two largest crypto ETF categories face redemption pressure.
