According to Eric Balchunas, the first-ever staked Ether and spot Solana ETFs could be launching soon, as the REX ETF filing has gone effective, indicating a likely near-term market debut. This development would mark the first spot Solana ETF, as currently only futures-based Solana products exist. The use of the '40 Act provides a faster path to market, although it requires additional regulatory steps. Traders should monitor these ETF launches closely, as their introduction could significantly increase institutional and retail access to both ETH and SOL, potentially boosting liquidity and impacting price action in the broader crypto market (Source: Eric Balchunas via Twitter, May 30, 2025).
