Digital-asset exchange-traded funds kicked off the week with a split picture: XRP and Solana products pulled in tens of millions of dollars on regulatory optimism, while Bitcoin funds eked out a modest gain and Ether funds kept sliding. Combined inflows across the four largest crypto ETF categories reached about $53 million Monday, with XRP ETFs alone accounting for $26 million of that total.
XRP ETFs ride the Clarity Act wave
The strongest demand hit XRP-linked ETFs, which brought in $26 million. Traders and allocators are betting that the Clarity Act — the pending U.S. legislation that would define when a token is a security — will finally give Ripple's native asset a clear legal lane. The bill has been winding through Congress since last year and is expected to reach a floor vote this summer. For now, the mere prospect of regulatory certainty appears to be enough to pull sidelined capital off the bench.
Solana funds see renewed appetite
Solana ETFs also posted strong inflows, though the facts don't specify a precise number. The flows reflect what one might call a rotation: with Bitcoin's price action relatively flat and Ether bleeding, investors are hunting for alternative exposure. Solana's ecosystem has been adding developer activity and DeFi volume this spring, and the ETF flows suggest that institutional money is starting to follow.
Bitcoin ETFs: modest but positive
Bitcoin ETFs recorded $27 million in net inflows — hardly a blockbuster Monday, but enough to keep the streak of positive weeks alive. The market's attention this week is on the Fed's upcoming minutes and any commentary from the SEC's enforcement division, so the modest number might reflect a wait-and-see posture among BTC-focused allocators.
Ether ETFs keep sliding
Ether ETFs continued to see capital outflows, extending a run that has now lasted several weeks. The reasons are familiar: persistent uncertainty about how Ethereum's staking yield will be treated under U.S. securities law, plus competition from faster layer-1 blockchains like Solana. Until the SEC or Congress offers a clear answer on whether staked ETH counts as a security, the outflows may keep weighing on Ether ETF flows.
The next real catalyst for ETF flows is the Clarity Act markup scheduled for May 20. If it passes committee with strong bipartisan support, the XRP and Solana flows could accelerate. If it stalls, expect the current rotation — into XRP and Solana, out of Ether — to persist.
