Bitcoin and Ethereum ETFs Bleed $1.5B in a Week as Solana Bucks the Trend

Spot ETF flow data for May 22 paints a stark picture for the two largest crypto assets. Bitcoin ETFs logged a single-day net outflow of 1,312 BTC ($101M) and a seven-day net outflow of 18,989 BTC ($1.46B), signalling sustained institutional de-risking rather than a one-off redemption spike. Ethereum ETFs fared no better, shedding 16,794 ETH ($35.62M) on the day and 129,315 ETH ($274.28M) over the trailing week.

The outlier in today's data is Solana. SOL-based ETF products recorded a daily inflow of 45,673 SOL ($3.97M) and a seven-day inflow of 123,743 SOL ($10.77M) — a modest but directionally meaningful contrast to the broad outflow trend hitting BTC and ETH vehicles.
