Spot Bitcoin ETFs shed 3,685 BTC (roughly $298.89M) on May 11, while spot Ethereum ETFs lost 6,492 ETH (about $15.1M) on the day. Solana spot ETFs moved the other way, adding 70,721 SOL worth roughly $6.76M.
Why it matters
The one-day prints are modest, but the contrast is the story: BTC and ETH products bled on Monday while SOL ETFs kept printing green. The weekly numbers still favor the majors — spot Bitcoin ETFs are net positive 7,287 BTC ($591.04M) over seven days and spot Ethereum ETFs are up 24,921 ETH ($57.97M) — so Monday's red bar is a wobble inside an otherwise constructive tape rather than a regime change.
Market impact
Solana spot ETFs are the outlier. Weekly net inflows of 451,400 SOL (around $43.15M) are running ahead of both BTC and ETH products on a percentage basis, and Monday's print suggests demand for SOL exposure is not waiting on Bitcoin's lead. Watch whether Tuesday's BTC and ETH flows resume positive — a second consecutive outflow day would be the first read on whether Monday was rotation into SOL or the start of a broader risk-off inside the ETF wrapper.
