币界网报道：Canary Capital has filed for the "Pengu ETF," a Solana-based exchange-traded fund, with the U.S. Securities and Exchange Commission (SEC). The proposed fund aims to track Solana's spot price, similar to existing Bitcoin and Ethereum ETFs. This move comes as Invesco and Galaxy Digital also seek SEC approval for their own Solana ETF, signaling growing institutional interest in SOL. The SEC has historically been cautious about crypto ETFs, only approving Bitcoin futures ETFs in 2021 and spot Bitcoin ETFs earlier this year. Analysts suggest Solana's strong performance and developer activity make it a prime candidate for ETF approval, though regulatory clarity remains a hurdle. The filing highlights increasing demand for diversified crypto investment products beyond Bitcoin and Ethereum.
