XRP and Solana spot ETFs recorded steady inflows in May, while Bitcoin funds recovered and Ethereum ETFs saw significant outflows amid shifting market
Institutional investors have shown a distinct preference for specific cryptocurrency spot ETFs throughout May, with XRP and Solana funds recording consistent inflows while Ethereum products faced a period of decline [1]. While Bitcoin ETFs experienced a volatile mid-month stretch, they managed to secure $131 million in inflows on May 14 following the passage of the CLARITY Act by the Senate Banking Committee [2].
Key takeaways
The divergence in ETF performance appears linked to specific events surrounding each asset. For XRP, the primary driver is the CLARITY Act, which seeks to codify the token as a digital commodity under federal law [2]. Following the bill's passage through the Senate Banking Committee on May 14, XRP ETFs saw significant activity, contributing to a cumulative inflow total that has now crossed $1.37 billion [1]. Standard Chartered projects that these inflows could reach between $4 billion and $8 billion by year-end if the legislation clears the full Senate before August [2].
Solana’s performance has been similarly supported by technical developments. The network’s Alpenglow upgrade, which aims to reduce block finality to 150 milliseconds, went live on the community testnet on May 11, coinciding with a $26.57 million inflow for Solana ETFs that same day [1]. Additionally, institutional interest was highlighted on May 14 when Dartmouth College’s endowment disclosed a $3.3 million position in the Bitwise Solana Staking ETF [1]. Unlike Bitcoin or Ethereum funds, the Bitwise Solana fund offers staking yields, providing investors with an additional incentive beyond price exposure [1].
In contrast to the growth seen in XRP and Solana, Ethereum ETFs have struggled, recording $189.46 million in outflows over a four-day period ending May 14 [1]. Analysts suggest that because Ethereum currently lacks a specific, positive catalyst on the calendar, it remains more vulnerable to broader macroeconomic pressures, such as rising interest rate expectations and inflation data [1]. While Bitcoin ETFs also faced pressure—losing $635 million on May 13—they demonstrated a capacity to rebound once positive regulatory news emerged [2].

Analysts suggest that rising inflation and higher interest rates have increased the opportunity cost of holding non-yielding assets, prompting investors to rotate capital into more competitive yield-bearing assets or other sectors like AI.
Despite the record-setting streak, the $2.8 billion to $3.45 billion in outflows represents less than 8% of the over $36 billion in net inflows accumulated since the ETFs launched.
Yes, Ethereum spot ETFs also faced a ten-day streak of outflows, totaling approximately $216 million, indicating that the trend was not limited to Bitcoin.
The current flow pattern suggests that institutional capital is increasingly sensitive to specific project milestones and regulatory clarity rather than general market conditions [1]. As the Senate prepares for a potential floor vote on the CLARITY Act in June, XRP remains positioned for further institutional scrutiny [2]. Meanwhile, Solana’s development trajectory, including the eventual mainnet rollout of Alpenglow, continues to attract interest [1]. For Ethereum, the lack of a near-term event leaves the asset in a difficult position, with analysts noting that the token may remain flat until a new catalyst emerges to anchor investor sentiment [1].
