Invesco Galaxy has filed an S-1 form with the U.S. Securities and Exchange Commission (SEC) to launch a Solana exchange-traded fund (ETF). This move highlights the increasing interest in cryptocurrency ETFs, following recent approvals and filings for Bitcoin and Ethereum ETFs. The proposed Solana ETF aims to provide investors with exposure to the Solana blockchain's native cryptocurrency, SOL, as institutional interest in diverse crypto assets continues to grow. In related developments, the CBOE has submitted a 19b-4 filing for the CANARY PENGU ETF, positioning $PENGU as the second memecoin, after $DOGE, to undergo SEC review. This filing is part of a broader trend of expanding crypto ETF offerings, which now include major cryptocurrencies like Bitcoin, Solana, and XRP. These filings reflect the evolving landscape of crypto investments as traditional financial institutions increasingly engage with digital assets.
