Spot Bitcoin ETFs absorbed +7,524 BTC ($603.14M) on May 4, the largest single-day net inflow of the cycle, with 7-day flow back in the green at +1,487 BTC ($119.21M).
Ethereum ETFs flipped positive on the day with +41,739 ETH ($98.92M) in net inflows, breaking a six-day streak of red that had pulled 7-day flow to -57,584 ETH (-$136.47M).
Why it matters
The BTC print is the headline — $603M in a single day is a top-quartile flow event for the product cohort and resets the conversation after weeks of muted demand. But the ETH swing is the structural read: $98.92M back into the books in one session after a week of persistent outflows is the kind of reversal that typically signals rebalancing has run its course, not capitulation.
Market impact
Solana ETFs stayed in the red across both windows — -11,767 SOL (-$1M) on the day and -22,498 SOL (-$1.91M) over the week — but the dollar magnitudes are small enough that the divergence reads as BTC and ETH consolidating institutional mindshare rather than SOL losing ground outright. Watch tomorrow's ETH print: a second consecutive green day would confirm the rebalance thesis, while a return to red would frame Monday as a one-off.
